Android Battery Life, a pretty successful website has been made in order to help android users achieve better battery life while still using many functions and apps. All of these guides are available, with screenshots, at www.androidbatterylife.com
It's my 2000th post here on xda, and I wanna make it special
PORTAL! http://www.xda-developers.com/android/battery-saving-mega-guide-celebrating-users-2000th-post/
A lot of users are thinking that everything mentioned should be applied. You don't have to apply all of them, just apply what you think works for you. This is more of an index of guides, if you will.
Yes, this is in the Android Q&A, Help & Troubleshooting because of the word "Troubleshooting"... I'm shooting your "Low battery life" trouble in the face.
So let's begin:
The guide is split into 3 parts: Easy, Medium, and Advanced.
First up is... you guessed it..
Easy
Screen / Display LINK
If you go to Settings>Battery, you’ll clearly see that “Screen” has the biggest bar of about 40-60%. The bigger the bar (and the number), the bigger the battery drain. We’ll try to lower that bar as much as we can.
Brightness
First of all, to reduce the battery drain caused by the display, click on the Screen button, then click display (it’s the same as going to Settings>Display), then click on brightness, untick Auto-Brightness if it’s ticked and lower the brightness to minimum.
Explanation: A brighter screen means the screen is emitting more light, which consumes more battery. So lowering the brightness makes the screen use less battery juice.
Wallpaper
Second thing to do to reduce the “Screen” battery consumption is having a Static Wallpaper, and not a Live Wallpaper. So go to Settings>Display and click Wallpaper, and pick any wallpaper you want except the wallpapers from the Live Wallpapers list.
Explanation: Live Wallpapers use the CPU (and possibly the GPU) to make the image move. So the phone is using the CPU to process these images, which means more battery sucking, and we don’t want that.
Sleep
Again, go to Settings>Display, and click Sleep (aka screen timeout) and set that to something less than 1 minute. I personally use 30 seconds and it’s good enough for day-to-day use.
Explanation: The more time the screen is on, the higher is the battery usage, because the screen won’t be using the battery when it’s off…
Framework Animation
Fourth thing to do is disable the Framework Animations. Framework Animations are the animations you see when you switch from an app to another app, or when you press home, or back, or recent apps buttons. To turn those off go to Settings>Developer options (if you don’t see that, then go to About Phone and press the Build Number button 8 times, then go back), scroll down to drawing section, and set Window animation scale, Transition animation scale, and Animator duration scale to “Animation off”.
Explanation: Framework Animations use the GPU (and possibly the CPU) to draw the frames of the animations, so by turning them off, you’re pulling some load off of the GPU and CPU to make the battery life better.
Widgets
Believe it or not, widgets can greatly affect battery life, it's because they update themselves regularly. This can wake up the phone a lot of times. So the best way to prevent this is to remove all the widgets on the homescreen.... and maybe keep the ones that don't update themselves much.
Remember, everything that’s shown on-screen that isn't app related is registered as “Screen” in the battery window. So to lower that, you have to compromise every little thing that’s shown on the screen.

Google Services LINK
One major issue you may face with Google Services is the location battery drain. This was born in Android 4.2.2 and can be easily fixed by just unticking a button.
Problem
The real problem is, in one word, Location.
Google Services such as Gmail, Now, Maps, and Google+ constantly polls your location using your wifi (if you're connected) or your cell network. And every time Google Services poll your location, your battery gets affected. So what's the solution to that?
Solution
Further research by Galaxo60 proved that going to Settings - Location Settings (or Location on android 4.4), and unticking WiFi & mobile network location (or setting the Mode to Device Only) prevents Google Services from polling your location, thus preventing the battery drain
So disable the WiFi & mobile network location option, and actually tick and turn on GPS satellites. (It's just like setting the Mode to Device only on KitKat)
But why do that? Why should I turn on GPS?
Picture taken using Android 4.4 KitKat
Explanation
Google Services don't use your GPS to poll your location, so your GPS actually stays offline most of the time; and the reason you should enable GPS is to "Let apps that have asked your permission use your location information".

Go Dark LINK
Some devices have AMOLED or SAMOLED (Super-AMOLED) screens, like the Samsung Galaxy SII and the Motorola Moto X. The following method is helpful for these kind of devices.
You may check what's your screen type to see if it's AMOLED or not. If it's not, this method won't help you achieve better battery life, but may help your eyes
What's AMOLED?
AMOLED is a screen type designed to get the highest contrast a screen can get to. Black pixels turn themselves off, unlike the IPS screens that always require a backlight. So AMOLED has less battery consumption than most screen types.
What to do?
Try turning everything as dark as you can. So make the wallpaper have as much black areas as possible, and use dark apps. The best way to convert most apps to dark apps is downloading Team Black Out Updater. From that app, download the apps you want to make them darker and install them. Some apps require having root because you have to flash them via recovery.
This consumes less power
This consumes more power
Explanation
By turning most things dark/black, more pixels in the AMOLED screen will turn off, thus lowering the power consumption caused by the screen.
Remember, this is only for AMOLED screens, IPS/LCD screens will still consume the same power from the battery.

Turn Off Auto-Sync LINK
Auto-Sync constantly checks the data on the phone and the data on the cloud, and adds the missing files. In other words, Auto-Sync = wasted battery.
Turn off Auto-Sync
Go to settings, scroll down to you google account, tap it and tap on your gmail. Then uncheck all the items on the list.
This is wrong. Now untick them!
Explanation
Auto-Sync consumes a lot of data and battery. By unchecking the items, Auto-Sync will turn off, and thus saving battery AND data!

Turn Off NFC LINK
NFC is wireless, and wireless consumes battery. So turning off NFC will make the battery life slightly better.
NFC off when not needed
If you don't use NFC, go to settings > more > and turn it off. Android beam will grey out because it needs NFC, we don't need that either.
Explanation
NFC consumes a lot of battery if you keep your screen on most of the time. So by turning it off, we're improving battery life while the screen is on.

NO Task managers/Hibernators LINK
Yes... I know... Weird right? Don't be misguided, and understand what's happening inside android before doing anything.
Uninstall / Disable Task Managers / Killers / Hibernators
If you have any Task killer, or Task manager apps installed, either disable them if you can, or uninstall them.
Explanation
Android learns the way you use it. It knows which apps you like best and pre-opens them and puts them in RAM so that they get opened faster. Android keeps a log of how much time you've been spending on an app.
By using a Task killer, you're breaking this log, thus preventing Android from learning how you use it. The results?
Android will be loading every app you open from scratch.
Android will get slower.
Android will be wasting battery.
So uninstall those "battery killers" and let Android do the work instead.

Use ART LINK
Yes... ART... Not art, but ART... It's an Android 4.4 KitKat specific thing...
What is ART?
ART is a runtime replacement of the Dalvik runtime. It's the way the phone handles apps. Dalvik used to install apps fast, and conserve some space after the installation, but it compiles the app as soon as you open it, and runs it on a Virtual Machine (if it's not a native app).
ART pre-compiles the app on installation, which takes up a little bit (teeny tiny) more space, but makes apps faster to open, and over all performance better.
Switch to ART
Go to settings, developer options, and tap on select runtime, then use ART and reboot. It'll take some time to finish booting the first time it's running ART, but when it's done optimizing apps it'll be worth the wait.
Explanation
ART demands less CPU power to process things over time. It pre-compiles apps just once so that when you open an app, the CPU won't work as much to compile the app just-in-time (JIT). So, less CPU work, less battery consumption, more battery juice, and more performance!

Pick the correct charger LINK
I can't put direct links to chargers, so go HERE to the relevant page and see the chargers from there.
Is a fast charger better? or is it the slow one?
Use the Right Charger
A slow charger relaxes the battery, making it last longer when it fully charges. So, for a better battery life, use a slow charger at night when you're sleeping, or when you don't need to charge it quickly.
I recommend using this charger*: it's small, looks good, and it's slow with a 1A power output... Perfect for what we want.
If you're in a hurry, and your phone's battery has little juice left, you may want to charge it pretty quickly. In this situation, you won't care about the relaxation of the battery, so you should use a fast charger.
Something like this charger* should help a lot in achieving what you need. It also has a second slot it you have to charge another device. Use the A slot to charge faster with its 2.4A power.
You can also use a car charger if your phone's battery suddenly dies while you're not home.
This car charger* is perfect because it's fast enough to revive your phone and gives you enough juice to save the day.
So be wise and use the right charger for the right situation, so that you can achieve the best battery life possible.

Have a Spare Battery / Power Bank LINK
Sometimes, your battery will die, whatever you do...
Have a Spare Battery
In that case, if you have a phone with removable battery like any current Samsung device, equipping another spare battery could be very useful. If your battery is almost dead, just turn off the phone, open it up, and put your spare battery in. Voila, insta-charge
Have a Battery Bank
One great gadget to own with your phone is a backup power bank. This portable power bank (see link of the page HERE) is awesome because it's universal, and has a 13000 mAh capacity which can charge your phone about 5 times!
So if you don't want to scratch your head to do tweaks, you can use spare batteries or power banks to save the day

Know How to Use Android LINK
It's all about how you use it...
We see a lot of users that use Android the wrong way. We see people setting their screen timeout to 30 minutes because "whenever I want to chat, the screen keeps turning off". We also see a lot of users, even devs and power users, constantly pressing the back button to go home.
Know How to Use Android
If you have the screen problem where whenever you want to interact with the screen, it turns off, don't turn the screen timeout up. Turn it down, so that the screen turns off sooner, and saves battery.
And to go home, there's a button for that for a reason! Use it! Pressing back over and over again closes the app, and clears it from your device's RAM. When you re-open the app, it will open from scratch, so your phone will be slower, and will consume more battery since it's using more CPU power.
So use the home button, try to keep as much apps in RAM as possible, stop "clearing all" apps from RAM, and save battery!
Explanation
RAM, either full or empty, consumes the same amount of electricity, unlike RAM in computers.
The CPU copies data from storage to RAM and then runs the app. If the app is already in RAM, the CPU won't reopen it, it'll directly use it.
So making the RAM full of opened apps helps the CPU. The phone becomes faster, and the need of electricity running through the CPU to open the app is now nonexistent.
Also, Android keeps a log of how you use your phone and pre-opens the apps you need. If you constantly kill and clear out apps, you're breaking that log. So when clearing apps, you're not letting Android learn the way you use it. This results in a slower experience, and more battery drain.

Deactivate Auto-Rotate LINK
Auto Rotation isn't always needed... right?
Disable Auto Rotation
Go to Settings, Display, Rotation, and turn off Auto-rotate.
Explanation
Auto-rotate uses the phone's G-Sensor to see how you're holding the phone. By turning off Auto Rotation, you're using less hardware, thus using less battery

Turn on Airplane Mode LINK
When in low signal places, it's a hassle trying to find that precious signal...
Turn on Airplane Mode
Whenever you feel that the mobile signal is getting too low, turn on airplane mode if you don't need to call someone. Go to settings, More, and check Airplane mode to turn it on.
Explanation
The phone wants you to stay connected to a cell tower whenever possible. On low signal places, the phone will try harder to find a tower to connect to, and that drain a lot of battery. So turning on Airplane Mode makes your phone rest and not search for any tower, thus saving battery.

Use a Light Theme for LCD Screens LINK
AMOLED will consume less battery on the dark theme, LCD isn't affected by that...
Use a Light Theme for LCD
Using a lighter theme with more white in it helps your eyes, because you can lower the brightness even more and still see the screen just fine.
Explanation
The lower the brightness, the better the battery life. So a lighter theme is what we want, so we can reduce the brightness and still see everything.

Charge You Battery Correctly LINK
It's called a battery cycle, not a quarter of it
Charge it correctly
Don't let your battery go down to 0%, charge it while it's about 50%.
Explanation
No matter what charger you're using (either a slow or a fast one), the battery is greatly affected by the frequency of the charges. Our phones have different batteries than past devices had, so battery life cycles are a bit different as we used to think.

Use Widgets with Manual Refresh LINK
Widgets update themselves a lot... but there's a solution for that.
Use Manual Refreshed Widgets
Check every widget you have, and see whether you can set it to refresh whenever you click on it, or do something to refresh it.
Explanation
Auto-refreshing widgets make the phone wake up a lot and do some processing which can use the battery. By making them manual, you are controlling the frequency of the refreshes, and you are forbidding the widgets to refresh while the phone is asleep.

Do Not Rely On Battery Discharge Rate LINK
Look! Left it overnight and only lost 2%! This is about 0.25%/hr!
WRONG!
The battery acts like a capacitor (not exactly like it, but very similar to it), so whenever its charge is changed, the discharge / charge rate will change with it.
So, if you leave your phone overnight at 100%, you'll get a rate of x%/hr. If you leave it at 50%, you'll get a rate of y%/hr where x and y are very different.
It's only a matter of experimenting where is the sweet spot of battery percentage that you should have when keeping it overnight.

Do Not Wipe Battery Stats LINK
Some people do that a lot... but why?
What's Battery Stats?
Battery stats is basically a file in Android that stores the battery history. The longer the battery stats is, the more accurate the battery percentage reading is.
Why not wipe it?
Wiping battery stats is like tinkering with the fuel gauge in your car: you won't get more gas if you glue the gauge's needle at Full.
The problem is that wiping battery stats will give you wrong readings. Users thought that wiping it will make the battery "hold the charge better". This is wrong because doing so will break Android's battery reading, and that's why it will show you a higher percentage for a longer time.

Do Not Buy Cheap Batteries LINK
Wow! A 2500 mAh battery for my Galaxy Ace! And the same size of the original!
The problem here is that some users order a battery with a higher mAh value for a very low price. They get their 2500 mAh battery and put it in the phone. The device would last a lot longer now before its battery dies.
Now let's not forget why they ordered such a battery. It's most probably because their old battery is just exhausted and isn't lasting much. So no matter what battery they get, they'll notice a big difference in battery life.
Usually these cheap batteries are advertised as 2500 mAh, while they're actually a lot less.
So if you want to replace your old battery, try getting an original one.

Thanks to all of you who gave me more ideas on how to achieve better battery life
Medium
Undervolt LINK
The CPU is the biggest battery consumer, and it needs voltage from the battery. If we decrease that, we'll gain some battery life.
Undervolt your CPU
Assuming you have TricksterMOD, launch it and go to the specific window. Scroll down to CPU Voltages, then click Profile, and save the Profile as Default.
Now hit the minus/plus button right above where it now says "Default". When the window pops up, hit the minus button JUST ONCE. Every time you hit the minus button you undervolt by 12500 mV, and we'll call that a "step"; so undervolt by one step.
Hit the check mark button to apply.
Explanation
Every time you undervolt by a step, the CPU will demand less and less from the battery to run. This improves the battery by just a bit. It's mainly to avoid temperature throttling, but it also improves battery.

Increasing SD card Read-Ahead Value LINK
Whether or not you have an SD card, this helps...
Increase readahead Value
Go to TricksterMOD, swipe to general, and click Read Ahead Buffer Size under the I/O Control section. Set it to 3072 (Value is in KB, so it's 3MB)
Explanation
The bigger the read-ahead buffer is, the better the SDcard can predict what command would come next. It prepares itself to do a command before it's even issued. This gives you better performance, and a potential increase of battery life because generating 3MB is nothing compared to the performance benefit.
Check out this Spreadsheet from broodplank.net for more info on the benefits of read-ahead.

Advanced
Underclocking LINK
One major battery drainer is the CPU, so if you don't really use the phone much, and you don't care about games, you should probably consider underclocking it to get that precious juice back.
Requirements
You must be rooted and have a kernel that supports overclocking. You may find out how to root by doing a little online research because every device has its own rooting method (for example, I wrote a fully detailed guide on how to root your Nexus 4).
CPU Underclocking
Warning: Underclocking the CPU too much could result in an SOD (Sleep Of Death) which makes the phone sleep and not turn on without pulling the battery.
First of all, we need a controller, or a daemon to control the CPU's clock speeds. So go ahead and download TricksterMOD from the Play store, we'll be using that to underclock the CPU.
Now enter it and grant su permissions, swipe from left to right and select the general menu, scroll down to CPU frequency control and tick frequency lock, then click on the number next to the min button, and choose the smallest number in the list.
Then, click on the number next to the max button and choose something a little less than you CPU's stock frequency... on a Nexus 4, the stock frequency is 1.5 GHz (or 1512000) so I picked 1.2 GHz (or 1242000).
Now swipe down to CPU Governor Control and click the button next to the Governor Button, and select conservative. If you don't have conservative in the list, pick ondemand. Now hit the check mark button at the top of the app to apply the settings.
Explanation
We are lowering the CPU's clock speed which makes it a little slower, but consumes much less battery. We are also changing the way the frequencies are handled: with the conservative governor, the CPU will prefer staying at lower frequencies.
MP Decision
We're not done yet, swipe again from left to right and click specific, then look for MP Decision. If it's there, turn it off, if not then it's probably already off. Hit the check mark to apply the settings.
Explanation
MP Decision sees how you use the phone, and clocks the CPU relatively (if you're just chatting, it'll underclock. If you're playing games, it'll clock it to normal). We don't want that since we want to force underclock the CPU, so we turn this off to prevent it from playing with our settings.
GPU Underclocking
On that same screen, scroll down to GPU max frequency, and lower that just one step below the default clockspeed (400 MHz being the stock frequency on the Nexus 4, so let's set that to 320 MHz). Don't forget to hit the check mark button to apply the changes you've made.
Explanation
The GPU draws almost everything you see on the screen, so it's always active. Lowering its frequency has a big positive impact on battery life, which is what we want.
So that's basically it for the underclocking part, have fun playing with different governors and frequencies to get that precious Performance/Battery life point.

Detecting Wakelocks VS Installing Battery Saving Apps LINK
The most cliche thing to do when your battery doesn't last a day is install a battery saver app. However, I don't do it myself. I prefer detecting wakelocks in order to reduce battery consumption.
What is a Wakelock?
A wakelock is the moment where you turn the screen off, but the CPU stays awake doing something. It is the phenomenon when the CPU isn't asleep when the screen is off and it shouldn't be doing anything. Wakelocks usually drain battery because the CPU is kept awake and working while it should be resting.
Detecting a Wakelock
To detect a wakelock, install Wakelock Detector. Charge your phone, then unplug it and leave it with the screen turned off for about an hour or two. Then open the app and check the list of wakelocks.
The bigger the red bar on the top, the longer the wakelocks are. The top app is the number 1 culprit, and should be removed. If the top app is Google Services, it's probably the Location issue. If it's another app, check if there are syncing issues, and try making the sync interval a little longer, or turn off its notifications.
Explanation
We're trying to minimize the wakelocks caused by some apps to prevent the phone from being awakened. By doing that, we let the phone go to deep sleep faster, and longer. So, more battery life for us!
Another way to detect wakelocks (a little more pro)
Download and install betterbatterystats. It's basically a more pro version of Wakelock Detector. It also needs root for some functionality to work, but it gives you a more in-depth info about the wakelocks, CPU states, and network usage.
msm_hsic_host is the 3G... not to worry about that
So that's it for the wakelocks! Keep testing with different app configurations to achieve the best deep sleep mode for your phone, and get the most out of your battery.

Undervolt Even More! LINK
Undervolting once is fine. Undervolting twice is better. But undervolting a million times isn't good... So let's undervolt as much as we can.
Download Stability Test, run it, and hit the Scaling Stability Test button (root will be needed). Wait about 8 to 10 minutes while it's doing the process. If it doesn't crash, stop it by pressing the back button. Your phone is stable, you can undervolt even more.
So go to TricksterMOD and undervolt another step (remember to save a profile indicating how many steps you've undervolted). Then test again using stability test....
Keep doing that until something bad happens like the app crashing, or Android itself rebooting. When it does crash, "overvolt" back one step. At this point your CPU is running good while on the lowest voltage.
Explanation
Every time we undervolt by a step, we test the stability of the CPU so it doesn't crash. When it crashes, we overvolt back to the last voltage set that was stable, so that we get the lowest voltages our CPU can handle without going crazy, and thus, getting that slight push of the battery life.

Tweak Kernel Governors / Schedulers / KSM LINK
These tweaks only apply to certain kernels, since not all kernels allow you to modify these settings.
Governor, Schedulers, and KSM Tweaks
If you have a kernel tweaking app like tricksterMOD or faux clock, you are 90% free of all trouble of tweaking kernel governors.
First, find a kernel that has a specific and optimized governor. Turn off MPDecision if the kernel has an alternative (anything like "Intelli-Plug" will do). Now let's tweak!
We cannot cover the options for every kernel and every governor in the universe since each one has its own options and settings.
I am currently using faux kernel on my device. This kernel has intellidemand as the optimized governor. The aim of the kernel dev was to replace MPDecision with something better.
The links below provide some info about that kernel. These settings include tweaking the governor, schedulers and the KSM:
http://forum.xda-developers.com/nex...ernel-ver-031-mako-kk-4-4-uv-otg-cpu-t2008222 (the second post shows the recommended settings for faux kernel)
https://plus.google.com/+PaulReioux/posts/WFcjPqMEZgJ
Have fun tweaking!

Great guide, and great usage of your 2000th post! I've featured this on the XDA Portal
Great post!
I like using Screebl to prevent screen turning off and on unnecessarily. And use One Power Guard by onexuan. It really lessens the drain over night. I use Condi to automatically disable mobile data when connected to wifi at home as well.
very great guide! Just note something for people with HTC Sense. If you use the weather clock with current sensor, setting the location to GPS only will disable the location service (even if it's seems on, the widget will say it's off since it doesn't want to use the GPS). Because of that, you loose that feature if you do that.
Um, there's a problem with this guide. Instead of underclocking, overclock the processor. The faster the processor, the faster it gets jobs done, the faster it can go to sleep. These reduces long wakelocks and in general improves battery life.
I used to think the same way, but thinking that way is false.
What about Greenify?
idk about you, but greenify is useful.
EDIT: And for the fast charge/slow charge, do you have any proof?

So you're saying that it's better not to underclock and just use default values?
Hmm kind of skeptical about the home button thing. I usually back out of an app to prevent it from running in the background and consuming battery. Can anyone comment on this?

the fact that the app opens from scratch again makes the CPU work more and thus using more battery
if it's kept in the RAM, it'll stay paused, it won't use the CPU and makes your phone faster sincr it resumes the app, thus making your battery usage less.

you have a point if the user is a heavy user. But for normal users, the CPU won't be doing much; so underclocking it won't affect time, but it greatly improves battery life.

greenify freezes the app if you're not using it, so the phone will start it from scratch... it's a good app if you use it on apps that you barely use, but don't greenify the apps that you use frequently, it will badly affect your battery life.
as for the fast/slow charge, I have no proof since this is what i usually have as a personal experience, but i find out that my battery lasts longer when i charge it slower...

ah, you see, here's where it does make the good difference, keep doing that because you won't use the apps for about 8 hours, so it's better if they're closed.
i just posted this because i see people constantly closong the apps that they always use, but if you're not using the apps much (like when sleeping) it's better to kill them

First of all thanks! battery life is a never ending issue in any smartphone using the no animations, less widgets and device only location... hope it'll prove useful
I got a question... I use go power master which has a "screen off optimization" and i noticed that my battery barely drains itself while the phone is idle... it's not what you count as a task killer right?

So i love the evo 3d its great, but.. i dont even use it much and the battery is dead half way through the day. I bought a extra 2 battery and a external charger and just charge the other battery while use one and then switch when it gets to 5%. The replacement battery actually runs cooler than original. (according to battery monitor app) replacement runs at around 80F and original 90-100F
Im really a android newb and dont even know how to calibrate the touch screen (maybe there isnt evne a place to do it) im used to windows phones. Is there some tweaks to get more use out of the battery? also the battery says 93% when it finishes charging on the external. I guess it gets to 100 then starts to drain?
Sorry for my english and ranting. Thanks in advance
Have you rooted your phone? If not, you could try juice defender. It manages different things about your phone like data and what not. If you root it, then I suggest getting netarchys kernel. I'm using empiires beta ROM with netatchys kernel and my battery has lasted 20hrs (I haven't used it too much though. Just for XDA and text messaging)

have not had the need to root yet damn im lazy ill prob do tomarro. but was thinking about mighty mike rom. is empiires beta roma bad ass? i do alot of txting light calls and few games and it seems to die fast. maybe if i root and underclock it? i really dont need 2.4ghz of cpu power on a cellphone 99% the time. i can see if i was skyping and watching hd video but ive yet to do either those things.
Yep that's exactly how I use my phone for the most part. Its pretty good for a beta. Its suppose to be as AOSP as possible and sense is almost completely removed. Only problems I've had is that you can't change the ringtone or print from the default printer. And you can't view 3d pics because he has the AOSP gallery instead of the HTC one. And you can't get to the gallery from the camera app. I'm not a big picture taker though

Also check and see how many different things you have running in Sprint Zone, more than likely you will have everything turned on in settings. You need one up though, so I normally leave help on.

General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users (everyone, for now):
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The 3D's updated Sense 3.0 allows users to access these radios and other settings from the notification pulldown menu, , under the "Quick Settings" tab. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
Menu>Settings>Display>Screen Timeout
I use 30 seconds.
6. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
7. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to Menu>Settings>About Phone>Battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
-This is done by hitting menu>settings>monitoring enabled. Then after some time has passed, ht menu>monitoring>history>change tab to top apps, and see if anything is above, say, 2-4%.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Root Tips LIVE
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 3D Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 0-2 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 2-5 of screen on
* *Heavy usage – LOTS of video watching and games, 3D pics or video, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans. 5+ hours
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

guys go under themes and mods.. plenty of mods and apks for battery and batter%
I'm not typically on the phone for long amounts of continuous time, just to text then i turn the screen off (the display is on auto brightness), and i'm getting half a days battery, and display is showing up as using about 70% of my battery at any given time. Any ideas on what could help or anything? Any help is much appreciated
I've had the same thing since day one. What I always do is turn the brightness down when ever I can. It actually helps a lot. You'll notice a difference
Sent from my double barrel Shooter. BANG!
I play HD games for like 5 hours before battery runs out .
How often you sync your emails? every 15mins?
Also try UC , UV and turn your screen brightness to as low as you can.
I hardly ever sync my emails, i have it to auto-sync but i never open it. and whats a good kernel that allows me to do that?
% means nothing... Tell us how long your screen was on

if you never change your email sync setting, it is sync every 15 minutes I believe and that sure use a lot of juice.
Really you should try UV and UC and don't use force dual core if battery life is most important to you.
do you know what kernel would allow me to do this?
I take it most of you run manual w/ the screen fairly dim. I have had it on automatic. Im curious at about what percent auto hovers at. I know it auto adjusts but it probably has a general range it stays at - just curious if its like 35% or 55%.
What Percentage do you guys keep the brightness on for the best combination of battery life and visibility?

Mine is GSM version, so probablly can't help you. I am sure it will be all over the place in CDSM section.
I will start looking, thank you very much for helping me
I thought we've been over this. A high screen on percentage doesn't mean youre screen is killing the battery. It means its using the most amount of overall power. Technically that's a good thing. It means the rest of your phone (syncing, android processes, games, etc. Etc.) Aren't running wild in the background while the phone is asleep.
I'd be more worried if your display was only using 40% of the battery!
Turn auto brightness off.... It's too simple to pull down quick settings to change it that way,
Find an app to see running processes and services,might see stuff listed you have no idea was running.... Don't force close anything or mess with anything just use it as a refrence and find out if u really need the app or not, I use titanium back up to keep apps that I use just not to often and just restore them quickly use it and delete it.... I've seen a lot of games running in the background to give notifications and stuff, could be a lot of things... Best soulution to save batttery.... Buy a spare lol

Good day.
I have following battery consumation: display eat battery capacity very quickly. In decreasing area i was veawing 3d video trailers on youtube constantly. And during this perion screen eat 78% from all processes. Is it normal? Can i change this horrible appetites of screen? Backlight in automatic.
what app can effectively track our battery drain in MA?
battery monitor widget is quite erratic, or is it really that high during idle
-50 to -150ma (screen off)
I had installed battery monitor and noticed, that when using phone in internet plussed in usb for charging - BM shows -430mA!!! Is usb port so weak? why phone consume so many power?
Hi,
For my Galaxy S2, I'm on firmware 2.3.6 (on Samsung Stock ROM). Today , I run a little bit of field test, what will happen to my battery % when using the phone as GPS and charging it at the same time using the in-car cable.
For around 20-25 minutes of GPS usage, I lost 4%-5% of battery power. If I do cross-country GPS usage, that means, every hour, I'll loose around 12% of power. That gives me only around 7 hours of navigation.
It is enough, but if I do a lot of stop ... during these stops, the phone is not charged. So , probably the amount of usage is around 5 hours of navigation.
Does anyone has a good trick to reduce this consumption?
Hello there.
The first step you should take for reducing battery usage is flashing a different ROM and kernel. I'm using VillainRom 3.0 and SiyahKernel.
Second step would be installing voltage control from the market and either changing max frequency your phone runs at, undervolt a little (-100 mV each freq works like a charm for me) and also get 2nd core from the market and choose a single core mode.
Also the display is the most hungry part of the device so avoid using auto brightness and set your own.
Hope it helps youbto squeeze a little bit more power from your device.

google maps uses alot of battery and data to run.
stand alone navigation programs also use battery power. check settings if there battery saver.

SiyahKernel and Speedmod kernel - do you have experience when it comes to battery perfomance?
I just flashed another modem. I'm going to go for another "test-ride" on it..
if that didn't improve. i'll try the Siyakernel. Thanks..

Use a lot of battery is understandable, but i hope it'll be less than the amount of power going into the phone while charging..
I tested the 2.3.6 Samsung standard Kernel and SpeedMod.
I think the Google Navigation seems to use less power. The Papago still remain power hungry.
if you have 2.3.6 you should have system power saving in the settings menu, which should disable one of the processor's cores. it may be abit slower but see how that works for battery life
I have been messing around with system tuner app for a while now and I really like the program.
I would like to hear from people who have used this app and their results with various tweaks that this app provides.
in the boot settings menu:
1. forcing both CPU's online: this should technically give you a better battery life, since it puts less strain on on cpu at a time, has anyone had a good exprience using this?
2. Boost app loading: anyone had any significant improvement with this?
My own settings:
I usually clock my phone at 1.5 (on demand governor) even though faux's kernel allows 1.7 max. I put max clock for screen off at 384 and conservative governor.
I have Undervolted before but do not see a very significant battery difference so I just left it alone.
I tried out the autokill option of system tuner, I only tried to kill the ghost apps, to refrain from the cpu from having to keep restarting the phone, but this also seems to kill battery life...In my experience any type of task killer however detailed will reduce battery and does not increase performance, unless you're running a poorly written app that just needs to be killed.
I use three other programs to monitor my phone
1. system pannel: very good at finding rogue apps that kill cpu...I highly recommend the pro version, you can get a history of what has used cpu up to a week.
2. Onavo and My data manger which basically monitor my wifi and mobile traffic, Onavo only monitors mobile network traffic and lets you restrict apps to only wifi. however it does not measure wifi use of data. My data manager monitor both wifi and network usage but does not give you any options to do anything with the apps, it basically tells you what program is using data while on wifi and mobile.
If anyone has found a good balance between performance and battery saving, please do share.
Thank you.
I read some other guy also mentioned the all cpus on thing. im not sure but isnt it the same as making both processors work at the same time which leads to phone overheating? I will give it a try though. from what you noticed, do you like it more with both cpu on or is better the way it was?

technically this is how it's supposed to work pic attatched, but I don't know if our roms or even the dual core rom that's out works in this manner, if it did we would be seeing significant battery savings

will see then. hey seansk do you notice some kind of hesitation when trying to unlock the phone? when u press the unlock button at the top. I think that boost app loading thing causes this cuz when have it enabled the unlock button you have to press it twice to work, while when disabling that boost app loading thing all works fine...

I have widget locker and havn't had that problem...I just flashed faux's latest kernel and am in the process of re calibrating my battery, it seemed to jump from 100 to 90 in about 10 minutes!!!!!! now I noticed that happening...but I havn't had time to fully replicate it...i need more time..I believe it might have something to do with fauxes kernel, he mentioned that when screen goes off he it puts the phone into a low power consumption mode, but also has something that when you turn it on, is quick to turn on!!! we'll have to wait and see.
If you've been following this thread, just wanted make a quick update...I want to give you my results with system tuner tweaking. Forcing both cores online is a bad idea. It will literally kill your battery in a matter of a couple of hours. ICS will hopefully be different and utilize the cores how they should be, saving some battery and giving the amaze longer battery life!
On the other hand reducing reducing clock frequency on screen off will help in battery life (obviously).

yes still stock rooted, I put the governor on conservative and put the frequency to 384 or around there, while screen is off.
What helps most I found out is turning off all the radios like wifi and network data, (basically putting phone on airplane mode). Instead of dropping down 15 percent in 6 hours it drops like 3 when I turn airplane on. But like I've said before it's unrealistic I'm always recieving google talk, google voice, facebook updates and I have to have both of these on which unfortunately eats a lot of battery.
I keep switching back and forth between faux's kernel and stock and I'm actually finding stock gives me better battery life for some reason. Even though I set the clock speeds on both at 1.5 ghz.

Battery Life
Major battery drain is the screen, when on eats up all the juice, dimming helps a bit
charge source: usb vs AC charge
usb charging takes quite a while, AC charge quicker (~ an hour)
Also, from my observation, usb charged battery runs out quicker than AC charge
Data Connection, Juice defender helps a lot
turn off sync you don't need, like HTC sense

well the problem is its not my screen. It's when the phone is idle, I usually lose about 15 to 20 percent over night. if I turn off the radios it drops down to about 3 to 4 percent overnight....like I said before I can't turn off the radios...I constantly use google voice, google talk, facebook. And they require both a cell connection and a data connection. I hate to pay for more apps...I've already paid for a bunch of apps to control and see my phone's usage of cpu and battery...is the app really worth it? wish they had a lite version

while you sleep, you won't be checking for emails will you? but you expect to wake and see emails received.... that is where it comes in handy. with apps like tasker, you can automate some of this activities. tasker + syncer should be a good combo for you.

For what it is worth I am running BulletProof 2.3.1 and last night I took phone off charger at 10:00 PM, alarm goes off at 3:30 snoozing every 15 min until 4:15...Battery was at 100% still. It is now 7:00 AM and battery is at 96%.
This was after flashing back to BP around 8:00 PM.
I've noticed the same type of activity when in Airplane mode. Extremely low power consumption - fantastic.
Is it possible maybe to undervolt the Wifi/BT/Mobile radios? Would that make any difference or am I off base here?

You had something setup wrong then I think.. you can change how often in syncs while the screen is off, the default setting is for it to turn on data for 1 minute every 15 minutes. Most people don't need to know things so bad that they can't work with a 14 minute delay(at worst), and of couse the internet is on while screen is on, when you're actually using it.
I thought I would need to use juice defender, but since I switched to bulletproof, my usage last me an entire day. From 8am till 1am, usually with some to spare. The only tweak I made to cpu was to enable 192mhz, it isn't like there is a performance drop, but it did make a notable difference in battery life.
If I wanted to I could use juice defender to get more than one day out of it, and I keep a spare battery on me in case I really need to use the phone.. but haven't really needed it.

For what it is worth I am running BulletProof 2.3.1 and last night I took phone off charger at 10:00 PM, alarm goes off at 3:30 snoozing every 15 min until 4:15...Battery was at 100% still. It is now 7:00 AM and battery is at 96%.
This was after flashing back to BP around 8:00 PM.

How many apps have you installed?
I hve been using my phone on power saving mode from 2 days to save battery and to hve more life out of it. I wana ask tht it is ok to use it continuously on power saving mode forever??
Any ideas??
No problem in using power mode all the time. It's a feature Samsung enables to save battery
Yep. Can't see a problem except the expected performance downgrade etc.

Personally I hated the power saving modes in every smartphone i had cause it affects performance. I will buy a spsre battery and a charger. If you are ok with the performance in power saving mode you should use it!
Enjoy your phone to its maximal potential. Don't let the battery saving issue to disturb your user experience.

My phone doesn't decrease in performance with saving mode enabled. It is always fast.

Not the case with mine, I notice a decrease in performance. It most likely under clocks the CPU...
In regards to the original question, no there is nothing wrong with leaving the phone in power saver mode. In fact you could probably argue that its better as the phone creates less heat.
Ideally I'd like to overclock mine
Well there is no such thing as saving power without sacreficing preformance. (unless you undervolt it or use more power effectient drivers)
But you should be ok running in power save mode all the time, although I do question why you bought a top of the line smartphone then. I think you would have saved more power (and money) buying a lower end phone.
It does govern the cpu. You can uncheck it. I leave mine checked.

Truely speaking i cant see diiference of even 1% in comparison to power saving and normal mode. Any one knows y battrey depleting though good but at same rate in both modes??
juice defender app does a good job for me. i use the basic settings but you can tweak it to save more battery.
Power saving appears to cap the clock speed at 1.0 GHz rather than 1.4 GHz and it may also disable cores, too. Most of the time it feels just as responsive to use. It is less snappy for some apps and benchmarks quite a bit slower, but I feel I'm splitting hairs as it still feels quicker than my last handset.
I see two days of moderate use with Power Saving on. I don't quite see two days with it off, but the difference is probably not statistically significant and the device is still new.

im using a power saving application on Xperia S ... is it okay to keep it working all the time??
thank you ....
ButterMaker: first of all, wrong forum, also battery saving apps are known to interfere with androids way to handle memory so I would say no

Yes, should not use battery/ram optimization apps. They interfere with androids core system.
I uninstalled all these apps after trying and researching. They eat more battery then they save. I only use battery stats apps to keep a log of battery drain.
Now I easily get 40+ hours on my S3 with moderate uses.
