[Q] ICS Passion 9.2 battery life - Vibrant Q&A, Help & Troubleshooting

I just registered, so I can't ask this directly to the developer, but hopefully someone can help me out. I flashed the ICS *Passion* 9.2 beta after reading up on it and seeing all the rave reviews about it. It has been a couple days with a few charge cycles completed and my battery life is still in the hole. Does anybody have any idea why my battery life is so bad? I hardly use it, just to text a bit and browse the internet occasionally. I saw quite a few posts in it with people achieving 12-17 hours battery life with moderate use, and yet I can only manage 6 with light use. The battery menu shows the screen using quite a bit of battery, which is strange, because I have the screen off with the exception of a quick text. Help?

I have similar battery use issues. I believe you have to have it fully charged then wipe your battery stats in the Clockwork Rom Manager menu under advanced. Fully charge again and repeat the process several times. You are probably aware but if dataswitch or wi-fi is running while not using, it will drain bigtime.

Wrong about last part.
I run wifi 24/7 and get 20+ hours light use of course.
I'll give you some of my settings I did to make it like this when I get to a computer I don't like typing long things on phone.

There are some apps and explanations for download in my Battery Guide, post 3, that may help with this too.
Listen to Rider though. He's been on ICS since the beginning. Send some if those settings my way and ill put them in the guide if you want/don't mind.
HNY buddy.

Ok, i will list a few things I ALWAYS do on ICS right after flashing.
Settings> Display > Brightness to lowest ( i don't like the high brightness it hurts my eyes if i need it i turn it up) My Screen display time is set to 2 minutes (i don't think it matters unless if you just turn your screen on and leave it there)
Accounts and Sync > Sync everything right after flash and then disable syncing of Google Photos and Calendar (unless if absolutely necessary)
Also if you sync things like Gmail and what not, try to set the sync time 1 hour + mines set at a hour.
I also use Titanium Backup PRO to freeze DRM protect- , Email, and email exchange ( i only use GMAIL so i don't need another app taking any space) if you don't use gmail, freeze it.
I don't like using GPS because I know the places I go to. I know the roads near me etc. GPS shouldn't be THAT big of a problem if you remember to turn it off after using.
Settings> Location> all of mine are unchecked, if you do use GPS frequently then check the ones necessary. I don't like Google knowing where I live, it does no good just wastes a little bit more battery.
I use SETCPU(paid) you can use Voltage Control (free) and change your frequencies to minimum: 100 max: 1000 and then menu > set on boot or something similar. If you don't set it on boot, right after a reboot its going to change.
Thats basically all the things i do at a fresh rom flash. I might update this post if I miss something.

[Q] About Android....

Guys, don't ask me to search again... i really did... and didn't found any answer....
i am new on android.... and it's regarding the battery's life time...
i hope someone give me an answer here....
there're a lot android user saying about advanced task manager, juicedefender, v6 supercharger, cell standby, phone idle.... anyway... i got no answer at all....
few people using ATaskMan and improve their battery life, but few people said it just drain my battery... anyway...i don't see any improvement using that....
i used juice defender to keep the connectivity.... better than keep it all the time...
didn't see any improvement also....
i used setCpu too... keep it low at night.... i don't really know if it works....
all i want is keeping the data on as long as possible.... even on sleep.... to keep apps like viber, whatsapp, im+ and sometime to sync the apps like weather, facebook, twitter and email...
weather, facebook, twitter and email... these apps were set to manual... not automatic....
i don't call and messaging a lot.... just stay on in internet...
i don't play games a lot... maybe few minutes....
so my questions here...
1. did the apps on background really drain up the battery? because they are, who using v6 supercharger didn't have a problem with battery.... and it's not like ATaskMan... it's didn't kill the apps at all.... just manage the background apps...
2. did the widget also drain the battery? some people said so....
3. keep the data on all the time? i read in this forum... they keep their data on.... but, still having their phone more than a day... moveover... some guys get it over 2 till 4 days...
if it's about ROM, it should be same with other, who uses the same ROM...
and if it's about hardware... it should be from the first time i bought this phone....
i just want keep my phone as long as possible with data on.....
anyway.... i still keep tracking what drain my battery the most....
hope someone come with answer for this....
and sorry for my english.....
1. That depends on which apps are running in the background, but when your device is in standby it should go to "sleep", but if you've set some apps to update every 15 minutes, the phone will wake up (without turning the screen on of course) to update them. This will naturally use some battery. And remember that Android can handle all processes itself. You don't need to kill them yourself. That will actually decrease batterylife since the phone has to start the apps again everytime you kill them. A task manager is nice to have if an app is going rogue.
2. Widgets do use battery, and the widgets who are set to automatically update itself uses more battery (Facebook, Twitter, Weather etc.)
3. "This tip is one that seems counter-intuitive, but you can save a lot of wear and tear on your Android phone's battery if you tell it to keep the Wifi radio turned on and connected while the phone is sleeping. Your phone needs a lot of juice to keep pinging those cell towers, and even more to transmit data to and from them. Wifi radios use much less power because of their design, and they don't have to keep searching for a better access point. It's the way cellular data communication was designed, and it's a necessary evil.
But what if you're spending all day (or all evening) in one place, connected to Wifi? If you tell your phone to shut off Wifi when idle, it bounces back to cellular data (be it 2G, 3G, or 4G) and starts sucking down the electrons again when the screen shuts off. That's no good, and easy to fix:
Open the advanced Wifi settings by pressing the menu button, then Settings, Wireless & networks, Wi-Fi settings, and tapping the menu button again. You'll have a choice to either Scan, or go Advanced -- go Advanced.
Tap the Wi-Fi sleep policy entry, and you'll get a pop up dialog with the choices you see in the picture above. Choose Never.
Now even when your phone goes into standby mode, you'll stay connected to Wifi and be able to get mail and messages without turning the cell radio back on and trouncing your battery life. And for the times when you're not in an area with a Wifi connection, just shut Wifi off, either through the menu or with a handy toggle widget. Your battery will thank you for it."

The android OS has a built in task manger so using ATK or ATM is actually worse than if you don't.
But honestly rooting has made all of the difference. If you have time for it READ about what it means to root and the how-to's, youtube instrutional videos, etc.... just get your feet wet a lil bit. When/if you feel like it is something that you might be interested in, go ahead and do it. You wont regret it and you will diffidently be able to improve battery life with titanium backup which allows you to freeze apps that you dont need running.
Warning 1) you might become addicted to flashing ROMS... and 2) if you screw up your phone you can't blame anyone but yourself.

at least for my phone: regarding setcpu, you can raise the minimum frequency, increasing performance while hardly affecting battery life (at stock i had 245/600; now i have 480/600). turns out that if you set the minimum frequency low, it will take some juice to ramp the cpu back up
just a little tip
Just wanted to add: besides titanium backup, I'd also recommend gemini app manager and better battery stats. You can use gemini to edit an app's autorun permissions (ie, automatically starting at boot) for those apps you don't, can't or shouldn't uninstall/freeze. If you're having issues with your phone not sleeping better battery stats will help you identify what's keeping your phone awake.
Lastly, there is only so much you can do to optimize your battery life. In the end you're going to have to sacrifice some functionality for better battery life or vice versa. You just need to find the right balance you can live with.
What is the longest running time did you had on your phone? I reckon batteries are getting thinner and thinner and will not last long.
Apps are there to help you avoid manual work. If you switch of automation on all the apps then you will have to spent time and do it all manually and on the other hand how much life will you save lets say %15. Not worth it!
Best solution is to stick your handset to the charger while you are going to sleep!

i set it 300/300 at night... it's from 00.00 til 06.00 which i don't touch it.... i don't know, if it is a good idea.... i guess, background apps wouldn't using cpu so badly.... would it?

[Q] What apps are the biggest battery killers?

What app (not just category but actual app) do you find is the biggest drain on your battery?
I get about 12 hours on a full charge and see about a 1% drain every 5-7 minutes!
I am about to put a new ROM on my Note and since I tend to run it loaded with apps that I collect, I was wondering if anyone has a list of biggest amp-drainers.
Some apps have settings that let you modify their behavior (K9 Mail comes to mind) but settings can be a bit confusing when it comes to balancing utility to power drain.
So...that being said...
Give me a list of apps that you run that you know kill your battery anyway some that are so stingy they get the Android Scrooge Award for battery use.
Also...
what are some of your best general power-saving tips for power-users?
Use a black background.
Turn off all your radios if you're not using them.
Leave your GPS off and just use WiFi for locations if you need to. If you don't use locations, turn them off.
Anything with a light background will drain your battery quicker on an AMOLED. Always use black wherever you can.
Never let your battery go below 20% charge.
Don't use a task killer - it was necessary for the older versions of Android, it's not now.
Set your Facebook/Twitter/Weather/Stocks etc. to sync every 3, 6 or 12 hours, as opposed to instantly (I still sync mail instantly).
These are a few of my runtime-prolonging tips. As for apps, anything that pulls data, displays a lot of white or moving pictures, uses a radio/GPS, and runs constantly will be the biggest drain. Things like turning off notifications in Tapatalk/XDA etc. can save you a lot of juice.
If you want to know exactly what is going on with your battery, you can look in the settings to see what exactly is draining the battery (sorry, I cant remember exactly offhand where it is).
Personally, I use an app called Battery Widget Pro by 3c that gives me more information than I ever wanted to know about exactly what is going on with my battery (just look at the screenshots on the market).
For me, the biggest drainer is the screen and phone calls but I only have a few apps installed.
All of those are good, and I want to add that under advanced in Wifi, there is an option to turn off Wifi during sleep mode.
Usually it is three choices, Always on, On when charging only, and off.
Make sure to turn it off during sleep if you don't need it. That can be a battery drainer as well.

Do keep in mind tho that rogue apps or those that are scheduled to perform network activities will fall back to cellular data if wifi is off.
BeyondPod is one such app, I have it on a schedule to download new podcasts at certain times of the day and if wifi is off, it will use cellular data if available. However, BeyondPod does have an option to only download on Wifi, but not all apps offer this.

[Q] Transformer Prime Battery Issues

Sorry if this has done the rounds, but im new to forumn and none of the posts seem to have all my symtpoms.
I bought a few weeks ago a tf201. everything is great, bar two points.
1) - battery life is emmense when docked on the keyboard and in use, and undocked. BUT when i leave it docked it just seems to refuse to go to sleep and manages to chew up just about all the battery overnight. from the battery monitor in settings the wifi and screen stay on overnight so it loose 5-10% or so an hour.. not great
2) not sure if this is related to the above, but again only happens when docked. if it does go to sleep (i think). when i come to wake it, nothing happens. in the end i have to press the power and volume buttons to reset it, then it wakes back up again. interestingly when its dones this it doesnt appear to have lost much battery charge.
So it seems that either it doesnt want to sleep, or if it sleeps, it sleeps a little too much.
im running the latest OTA ICS update as of last week and havent got that much installed widget wise etc. Ive been pouring over the forums for people with similar issues and the nearest i can find is people recomending using flight mode apps to keep the tablet from completely sleeping. this sort of works but the batteries then need charging every 2-3 days, which is better than daily but not great.
any pearls of wisdom as this for me is ruining an otherwise great device...

Email Accounts set to "push"
Email clients connecting to Exchange usually have a "push" option that continuously syncs with the mail server. Some of them (like Touch down which is what I use) allow you to set off work times when it won't be polling the server so I set it not to poll between 10:00 PM and 6:00 AM.
Also, look at the accounts and sync area in the settings and see what other stuff is being synced. I had no idea until I looked just now how much stuff is getting synced under my gmail account. It's not just mail and calendars like I thought but also a long list of other things.
Then, looking under "Backup and Restore" in the settings, I'm seeing that it's doing a "backup app data, wifi passwords, and other data to google servers". I'm assuming that means all my mail etc. When I first set up the tablet a couple of days ago I noticed that all the wifi connections from my Droid 3 showed up so that was the first time I realized that my phone must be doing this too...
That's a security issue in that by my employer's rules, sensitive company data isn't supposed to be stored on other people's servers so my exchange data really should not be backed up to google. And it doesn't make any sense to do that anyway. If one of my devices dies and gets replaced, when I configure the account on the new device, all the data will sync from the mail server anyway.
The point being that I'm discovering that there is a huge amount of stuff being synced from my android devices that I didn't even realize. That could be bogging down the network (particularly if on a connection that's slow to begin with) and also causing battery drain.
I'm experimenting with turning a lot of stuff off that I don't figure I need - both for the phone and the tablet - to see what difference it makes.

The exchange DATA, meaning your actual mail does not get backed up explicitly anywhere with vanilla Asus/Google ICS Firmware. What it backs up is account settings, and the options you select. Backing up all your mail would be awesome (under the right circumstances, such as when you need that backed up, and some apps will do so, but generally for a fee.
OP, for battery concerns, make sure that in settings, Asus Customized setting that "Mobile Dock Battery Saving and "Disconnect network during sleep are both selected. The latter option stops most or all synching when sleeping.
It sounds like you are experiencing SOD (Sleep of Death) not quite as horrible as it sounds, but if you have to push power button and or/ Power + Volume for 8-10 seconds to get it bac, does it then vibrate and reboot, or just come back to the Homescreen imediately? If it's the first one, look up SOD. I have had only ONE event since .28 rolled, and before that perhaps a dozen on .21, and NONE before that so it's due to SOME recent changes to firmware, at least in my case. Interestingly, I was able to stop it on .21 by disabling the same option we have been discussing. The two battery savers in Asus customized, and WiFi, Advanced: "Keep WiFi on during sleep" (You have to hit the "three dot" menu and choose advanced from WiFi Settings.
Anyway keep us posted, and let me know if you have SOD, or just a deep sleep - if you REALLY want to know how often and how long your tablet spends in deep sleep get CPU Spy (no root require, I believe) and after several hours, it will let you know what the CPU has been doing, for what percent of that time. it is an AWESOME way to determine how much deep sleep you are experiencing with the device.

10% in one hour of using?? so 10 hours???
I guess you should be more than satisfied........:good:
possible win
Many thanks for the suggestions.
I think i was get the dreaded sleep of death as when it slept to 'wake' it i had to reboot it.
Ive run through all the suggestions here + a few suggestions from the forumns, setting wifi to never, adjusting the dock battery usage, checking my sync options. In sheer frustration i removed all widgets and removed a shed load of apps (both pre-installed and ones that i had installed) installed cpu spy and tested. interesting that it appears to be ok now. charged the dock and transformer up on firday night and its still got juice today, all be it that dock is nearly dead and the transformer has 80%+ thats with 2-3hrs use every day and obviously sleeping...
one thing i did note. when it was docked before and 'sleeping' in the transformer battery was low it would charge for long period when it was sleeping? it doesnt seem to do that now. if the transformer battery is low and i sleep it. the power \ charge light stays on for 10-15 mnutes then goes off.. so def looks like something was keepign it awake.
go to settings/asus customized settings and scroll down to battery saving and check the two power saving settings :good:

Problem with S3 Battery

When i fall asleep i just place my phone nearby the bed and its on airplane mode,wifi closed,data closed and generally no apps running(i think so).The battery is level (ex)50% and when i wake up,about 7 hours later its always about 15-20%.why this happen?
I checked the battery manager just after i waked up and the first was screen(56%) and after that adobe reader(10%)

Better battery stats does not work.dont know why.and i made my own post cause i cannot find the solution of the problem on other posts.try to be more polite to your answers
have you tried downloading the xda version of the better battery stats? if not here it is
http://forum.xda-developers.com/showthread.php?t=1179809
Is your phone rooted? Like others said, try to install the xda-forum version of BBS but it's weird because I did install the one from GPlay.
One of the first lead is the WiFi? Is it always turned on? There's a bug with it. Go into the advanced WiFi settings and set it to 'only if activated' (I don't know the exact spell in English but it's something like that).
But you better have to dl BBS & check the wakelocks.

what?
Underclock when you're not using your phone.
That will save battery.
If ur using stock TW. Put on power saving mode
PM Me if u want to know more.
Try using an app called easy battery saver and only use the cable and plug that came with your galaxy s3 it works for me, today I had eight hours after charge and using internet with 3g nearly continuously.
You would get much more by leaving it on standby.
Also restrict your background data, turn off your automatic updates at play store andturn off WiFi while screen is asleep.
Follow all these for better battery.
Use any battery investigation apk/widget (I'd recommend battery monitor widget) and look what is causing the drain...
may I guess: cell standby or gpsd?
guys i remember you that the cell phone is on flight mode with wifi,gps and data turned off
and, if you have a soft which contains a bug - you'll have such processes running.
It is up to you to install any apk which will contain more detailed statistics what actually is consuming so much juice.
If you do not want - no one would force you.

I checked the battery manager just after i waked up and the first was screen(56%) and after that adobe reader(10%)

I have the exactly same problem,30% drain overnight.That happens after updating to 4.1.1 JellyBean.With ICS never happened.
Go into the battery page, click on the graph and then post a screenshot of the detailed graph here. It is usually an app or process not letting the phone go into standby. Happened to me when I had my phone on ICS out of the box. I fixed that all up through the individual app settings and all was sweet. Then when I went from ICS to JB, the issue came up again and I had to go through the apps again to change the settings back. It seems that by updating from ICS to JB, certain settings get set back to default, which then does not allow the phone to go into standby.
Culprits that I have found are:
Facebook - set to manual refresh interval
Weather (or any weather widget) - manual refresh interval
Google play store - Turn off Google AdMob Ads
Any form of newsreader (I was using Pulse) - Turn off notification when there are new stories
Wifi advanced settings - Set Keep Wifi on during sleep to "Always"
Samsung account - Turn off sync
Samsung app store - Turn off Update Notification, turn off push notification, turn off ad preferences.

Maybe some apps running in background if you are using *viber* delete it
It makes proximity sensor always on.
Try delete apps like that

Guys please keep in mind that keeping the stock os without any custom kernel might be not as effective than using an adequate custom rom...
In addition remember, cooler temperatures cause ur battery to lose its charge faster...
So if ur phone is placed on the window shelf and its getting cold during the night it might cause ur battery to drop fast..
I made this observation with my sgs plus....
Hope i helped.

My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.

My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.
I’ve been having this same problem sense I got my phone about 2 months ago but now I’m finally just tired of it! My phone is rooted, using the stock ROM.
What I do to help battery life:
- Every morning I hold the home button and kill multitasking and kill all running aps in the background then I open autokill which automatically kills running apps in the background that are not needed.
- I have power saving enabled
- Easy Battery Saver running
After 7 hours of use I’m already at 15% and through out the day I barley use my phone. Its like this just about everyday. I use my phone about an hour of the entire day of web surfing and Facebook usage etc. The rest of the day I’m only texting and maybe taking 3 or 4 phone calls that last 10 mins. How much battery could that possibly take? A flip phone can do that and last 3 days..
I used my iPhone 4S much more during the day then I do the galaxy S3 because the S3 has terrible battery life.
On my iPhone I would have about 22% after everyday of using it for 11 hours down time = sleep and 4 hours of usage = texting, , phone calls, web surfing, games etc.
I don’t play games or watch movies on my S3. Only texting, instagram, facebook, websurfing which is about an hour a day usage. Also a couple minutes of GPS usage on some days.
What can I do to fix this? I don’t want a bigger battery that will make my phone any thicker.
I have pictures below showing usage through out the day and usage under battery.
Please help!
Thanks!
You screen is using most of your battery. Check the brightness levels. Are they on max or close to it? Switch it to auto

Oh thats easy.
You're phone is always "Awake". It doesn't go into Deep sleep like everyone elses. If you take a look at the first picture you linked with the graph, it shows that the phone is always AWAKE.
For comparison, I have attached mine as a reference but something is DEFINITELY keeping your phone awake.

Can't really see anything that stands out per say...
If you see anything on that thread or any apps on your phone that you think could be keeping it awake, just uninstall them. I would suggest trying to remove them a few at a time just to narrow down which ones are keeping the phone awake.
Also, apparently this app helps a lot (https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy) and Better Battery stats should give you a better idea of which apps use the CPU while your phone is trying to sleep.
Oh and remove any task managers you have installed.. Those tend to be the worst offenders.
One last thing, found this on another forum:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
Are you on the 3G network a lot or weak signal areas? Is your phone hot around the bottom? If yes to both, most likely it's because of the system attempting to find a better signal. When I was swapping out my SIMs, in various countries, I only have 3G network and my battery fully drains in 7hrs at idle. The only way i can go a whole day is to place my phone into airplane mode or wifi only to conserve the battery.
my battery runs at-most 13 hrs........................

Welcome to smartphones. The calls alone will drain the battery. Seven hours isn't horrible for all that. It isn't a flip phone.
why your phone is always awaking?

maybe you have to flash a new rom
If you want, you could try to flash a custom ROM. I had the same problem that you have, and I flashed Revolutionary S5, and now my phone lasts minimum two days with the same usage, maybe a bit more.
Too bad Tony Stark hasn't gotten involved

Titanium Backup will assist a little bit. When you do a backup of an apk it will tell you if the application is running. You can find all kinds of sneaky apps this way. Many of them were ones I didn't use and didn't really want. That will probably yield minimal results, though. Keeping a black background helps on my S3. Colors, widgets, and live backgrounds will drain the battery. Turn off the menu and back key lights. You know the buttons are there. Turn off all haptic feedback and key press sounds. Of course, try to lower the screen brightness. Leaving my data and sync on hasn't caused me any problems, but you will save some battery by turning them off when not in use. I also read a post about hidden menu options that ran even when they weren't meant to. That was an issue that destroyed battery life. Some ROMs also have settings for data connection type. You'll save power by telling your phone to not worry about gaining signals like 4g, 3g, etc. As other people have said, try out some ROMs that make battery life a big priority.
it CAN get better
if you want to have a good battery life, use custom rom and kernel (or a modified stock like omega rom), watch out for wakelocks + apply these settings:
