I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Get the original samsung 2000mah extended battery kit.
ahh the battery life talk again
brings back memories of the first days of the SGS2
never thought of reading one again

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

there are other tweaks with custom roms that aren't found in the stock rom (which provides better functionality).
btw, i also suggest u use setcpu to underclock your device to save more batt.

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

Beware using anything that isnt ondemand on samsung phones, can cause stuttering, that's what I found anyway.
As far as undervolting -25 to -50mv is a safe first bet.

That is wrong. I used to have a UGKG2 ROM and since I upgraded to XXKH3, the battery is MUCH better while the GPS pinpoints in less than 3 seconds with a 5meters accuracy.
Hi.. my first experience with S2 has not been great battery wise. I've found the battery life to be horrible. Even with all the battery saving features i.e. static background, widgets off, etc. etc., I have to charge the device twice a day. Its practically useless. I was thinking maybe there's some 3rd party ROM out there which would improve the battery life? I'm currently running stock 2.3.4. Any suggestions would be welcome..
try mikimod"s rom its really good for battery, and also sicopat<s rom< and modaco i find they are the best for longer battery
I've used VillianROM, Cognition, and CyanogenMod. I find that CyanogenMod gives the best battery, but your mileage may (or will, most likely) vary.

And you STILL do not know where to post? You have got to be kidding me. This belongs in GENERAL. Because I do not see how this is related to DEVELOPMENT.
Now that I have bashed your face in. I get 40-50 hours out of my phone. Try GREEN POWER from the market. It turns your data off when the screen are off. Also See my sig for what I run.
Hyperandoid1.3.2 with speedmodk2-1 gave me a battery life of over 2 days.

You will get mixed answers. People run different roms with different kernels. Some do a full discharge/charge before judging these kind of things, some don't. In the end the most important factor will be apps and usage.
Try what works best for you. And post in q/a section next time.

Best Rom So Fare.........
( SensatioN Rom 1.8 )
( Based on 2.3.5 XXK13 )
this is none wipe Rom.
Excellent review..
Try It..
Hope you'll Sensation Rom.
Before trying other roms/kernels check to see which apps are draining your battery so much, as for dual core phones the GS2 battery is really good, so in normal situations you shouldn't have to charge the battery twice a day.
I'm in Wanam 5.1 + siyah kernels and as many other users i get +2 days of battery.
@antiochasylum I've hardly had the need to post. In any case, any moderator can feel free to move this thread to General. @Sesshou about 57% is display. Rest of the entries are all negligible. Yet the batter evaporates..
Why no one mentioned MIUI ROMs..?
Are they not good in terms of battery life..?

so you are facing problems only after factory reset??

TouchWiz gives high battery drain compared to custom ROM's, probably due to the bloatware.
I will never use TouchWiz on an android/galaxy phone, I will always use custom ROMS

Incorrect.
ONE complete battery cycle will re calibrate the fuel gauge chip. Once when i cycled my battery it stuck on 1% for over 4 hours. It does NOT give you longer battery life, rather it re calibrates the battery indicator.
OP if you want better battery life try this:
Use a custom rom, or a frankenrom if you like the stock feel, or a rom modded for better battery life
Look into what services are running and remove the ones that are running when not expected
remove the facebook app,
use less widgets (since they use more battery),
choose a darker background (AMOLED screens use the most power for white),
turn down the brightness,
have GPS, WiFi, and Bluetooth off when not needed,
turn off auto updates,
anything that automatically checks for stuff, turn that off or increase the delay,
Use a kernel that supports under-volting and under-clocking. You have a powerful phone which rarely needs to use all the power. Under-volting and under-clocking can help you get even several hours longer out of your device without a noticeable impact
Turn off those damn task killers. Its more efficient to not have a task running than to close it every 5 minutes and have it auto start up again. task killers were great for android 1.3, not so great for 4.0
In my class there is one other guy with an S2 and every day i hear his battery beep at him that its dying. I can go about 2 days of similar usage with no battery problems. Why? Because i spent time and effort to learn why my battery was draining and how to make my device run as smooth as i can.
TLR Do some research. If you want everything given to you buy an iPhone.

Battery life on ICS is worse than gb but I can get 3 hour screen time and the phone lasts for over a day which is more than fine

quick tip
kernel settings or rom settings and quick qovernor setting switch it to ondemand
Hi guys.. ive been flashing all kinds of rom and kernel. In the end i find stock Ics with stock kernel gives me both the performance and battery life i need after removing useless start up and freezing unwanted apps.
Had been using the default touchwiz and suprising theres no lag or redraw or whatever issues. Only set back is i cant customize my stock rom.
Battery life wise i can get up to 6 hrs screen time or maybe more. Will post screenshot after i drain my battery.
On jellybean, batt drain is more noticeable regardless using stock or any other jb roms / kernels. Personally i dont like OCing or undervolting so pls dont mention abt those here.
I am wondering who else here share the same experience with both ICS and JB. Would u still stay on ics or jb?

I've recently returned to stock rom and kernel after trying warnamlite, miui and a few others. Stock is deco the next for battery. I'm getting nowhere near 6 hours screen time though. How are you stopping apps from starting up? Is this by freezing or have you used another method?

You got 6 hours of screentime with data/wifi on with ICS?
Personally I've been getting better battery life with MIUI on Jellybean, but I've also been using Siyah since the first day I flashed my ROM so that might also have something to do with it. I've had experience with stock ICS and MIUI ICS as well, and the battery drain was essentially the same. I'm running a heavily customized JDUltimate though. If you don't want to undervolt or flash another ROM/kernel then JD is a great alternative. I was using stock GB on my S2 with nothing but Juice Defender and I got pretty decent battery stats, though I can't remember them right now.

Hi .. yes approx 6hrs screen time. With only 3g. But i setted my display to around 20% brightness as im indoor most of the time. I usually use the same setup to test among roms and phones as ive got 2x S3 to play with. One of it is my gfs phone. She plays lots of games so i also hear her feedback regarding the roms and kernels i flashed for her.
I find using auto brightness actually drains the battery more with continus use. I also make sure i got only essential tasks ans apps running in backgrd. Btw i have whatsapp in backgrd all the time.

Yeah I have my brightness at the lowest setting most of the time as well, as the only time that I'm going to be in bright daylight is when I'm walking around, and I'm not going to be looking at my phone while I'm crossing the street and whatnot I figured that all of those "auto" settings actually drain more battery because of their constant turning off and on and adjusting and etc...it seems like it would consume unnecessary CPU power.
How do you manage which apps run in the background?

1. Root the phone
2. Install all the apps / games
3. Use ES task manager to remove unwanted startup
4. Use tit backup to freeze unwanted apps.
System apps like mapservice, secphone, samsung pushservice etc that runs in the background are frozen with tit backup and startup removed by ES task manager.
Result : No useless bloat running in your phones background. Better batt life and performance. I can achieve 300mb ram after a fresh reboot. Stays aroumd 400 to 500 range of ram after a day. Will observe ram a day more as i just flashed stock 3days ago.
But so far so good. Quad benchmark scores are a minimum 5.4k too! Will post screenshots on weekend.

Here are my ram usage after a days use. Task manager screenshot is proof of what i had been doing with my phone without any restart.
Cant post batt life yet cos my phone is still at 75% lol.

I went back to ICS cos of battery life I need phone that is stable first! and then battery that can last 12 hrs min with 4-5 screen time, unfortunatly ICS from my experience is just fine.Shame I want JB as well but need to be at least stable as ICS

Yeah fully agreed. Cos i need my phone for woek. Only draw back on an odexed stock rom is it cant be themed. But then again.. doesnt really matter to me lol.

I do care if I can change system stuff in the rom but Stability FIRST I just hope SAMSUNG will do it right this time and will provide Stable 4.1 Sammy I belive if you could do ICS stable then 4.1 will be grater for battery as well.Hope the wait for Btu is worth waiting

An Aussie? Smutty humour? Never!
(I also had a juvenile chuckle earlier when someone said tit backup!)
So far my experience is in ICS's favour.
Ok. JB is latest. FIne.
BUT TELL ME SOMETHING WE CAN DO IN JB AND NOT IN ICS?
I didnt see even a single sort of such think except some added settings in settings app.
Even looks are same.
We can easily mod the ICS rom to make it look better.
For looks and functions of JB, we can use launchers ofcourse!
And personally, in JB, my ram normal usage was 500+MB.
In ICS, with same apps, its 200-300 MB. How and Why? Both stock kernels.
Also, i am used to playing games while charging. In JB, the battery only declined, even while charging when i played game. But in ics, there is charging instead of discharging even when i play games.
Therefore, jb is mess for me! So unstable with lesser battery....

Yeah, I typed out several replies, not sure what would get me banned but I am sure a couple of them would've been close.
Users want update because its an update not because its better other wise noobs would not have flashed leaked test roms or Polish firmware .

Hey friends I am currently running the OMEGA v28 4.1.1 JB ROM on my international GS3 i9300 and it is also rooted of course and I don't think I'm being paranoid but my battery life has took a massive drop since rooting my device. I am not overclocking mu CPU and I have tried out some rooted apps like battery saver for example and I actually think it made it worse. I have all the usual setting disabled to allow for optimal battery life like brightness right down, auto sync off, wi-fi off when the phone is locked I also only use the wi-fi manually if and when I need it and all that good stuff like smart stay and vibration off. I am wondering if anyone knows of something I'm not trying???
Had it charged to 100% this morning at 9PM and by 1PM I'm down to 79% already and I haven't made any calls and only used it to check my email and facebook for around 10 mins!!! is this normal for everyone else???
:crying::crying::crying:
Cheers
Gary
Sound normal for Sammy JB rom.
Some said Facebook is also causing the battery drains.
Sent from my GT-I9300 using xda app-developers app
Did you reset your battery stats? Charge to 100%, reset battery stats from CWM or delete batterystats.bin -file, let the battery run out.
You might want to use currentwidget to log your battery usage.
I noticed big battery drop between 4.0.4 and 4.1.1 used to get 24 hours one charge 4 hours screen time. Now I get only about 12 hours.
Might just be me :/

I'm using also omega rom v28, have it installed recently. I cannot say how good is the battery with this rom, but so far I have like 56% in 20h, with 2h screen, sopcast 30min, voice cals 37mins....etc (also using wifi manually when needed)
Try out different roms and find out what works for you.
You can also use an app like BetterBatteryStats to check what's draining your battery. Its just to check whats use power.
Don't use batterysaving apps most of the time they are making it worse
I'm running Omega ROM V27.2 and yes it's normal to have a difference about battery life between ICS & JB.
To improve my battery life I installed the phenomenal extreme kernel, and now I'm totally happy with it. You should take a look to its topic in the GS3 Android Development forum. The dev developed 3 versions of his kernel to fit to most of the phone.
Also as others told you, you should get BBS app to point out the wakelocks & define which app is your problem.
Personally, I'm at 45% charged, and already used it during 21h 10m including more than 2 hours screen on. My auto-sync is always on and my WiFi only when I enable it. I'm using a live wallpaper and a lot Twitter.
When I do nothing I can reach more than 2 days.

Hallo,
I have the OMEGA v28 4.1.1 JB ROM flashed on Thuersday and i´m testing the ROM at a long time.
I use the Phenomenal4.0Medium Kernel and i must say the BatteryLife is very good. I`m working over 15 ours with him and i have 58 % on it.
My WIFI is every time on and Autosync when i use my calender and planners. For me a good app handdling battery life is "GREENPower" in Market Place.
But it´s my idea.
Here is the Link for the phenomenal kernel in xda android Galaxy S3 Deverlopment:

Thanks guys for the info
I will give all this a try and see how I get on. Cheers for all your input.

Thanks for the help I have installed the phenomenal kernal, hope it helps a little.

As he recommends ...identifying and reducing your wakelocks should be your primary concern. Been reading loads from developers that the insecure jb kernels themselves should already provide good battery management.

Start with a rom and minimum apps and test that .

that is exactly why i reverted back to ICS.........JB is nice and smooth but "eats" battery quickly.........now,battery life problem on my i9300,solved
Hey guys, if you are going to use custom ROM's you should be prepared for bad battery. The developers are adding so many different features and hacking certain apps to make them work in their ROM's without a lot of investigation into what the reprecussions to battery are. I used to always use custom ROM's but haven't installed one in about 6 months and haven't any problems with battery life. I have the latest JB on my 9300 and battery life is very good. I use GSAM to watch apps that want to go rouge and start sucking battery life. Media Player Service is a big offender as is Facebook. Also stock widgets that get placed by these JB ROM's are always pinging for new data and kill battery quickly. Get rid of them! If you have a stock ROM and are getting bad battery, 99% of the time it will be bad apps, your job is to determine which ones they are and apps like betterbatterystats and GSAM work great to help diagnose the issue.
can anybody else confirm the above post? because i am not sure about the custom roms.

I will soon have an S3 so I cannot speak specifically about this device / ROM(s).
What I know from using a lot of Android devices and testing original ROMs vs. custom ROMs:
- original ROMs have too much garbage built-in apps and are slower
- original ROMs have everything working
- custom ROMs are much cleaner and faster
- custom ROMs have (too) much problems, something always not working 100%
- custom ROMs usually have stability & battery issues
My personal advice:
- install latest ORIGINAL ROM.
- root it
- install the free app "App Backup & Restore" from Google Play
- search unuseful apps from Samsung (& others) and block the autorun of these apps (note: do not block basic android or samsung apps, as phone, contacts, etc)
I use this method for 1.5 years and this way my Android is clean (you can save over 100-150Mb RAM), FAST and much better battery. Try it.
In the end, if original ROMs have too many original apps, custom ROMs have to many tweeks that in the end, for my taste, the original ROMs + App Backup & Restore win hands down.

I have always had custom roms on all my android devices but at the moment I am running stock ics in my s3.
I don't think the S3 needs it.
To be honest I find a lot of the stock based roms full of changes I don't really need, ARHD was a great Rom but recently has started to lag really badly for me (and some other users) so I went back to stock just to see and so far I can't complain. Smooth, fast and the battery is as good if not better than the custom roms.
If the camera didn't suck so bad on AOSP I would be there in a instant
