I have Samsung Galaxy S2 with ICS 4.0.3.
From many days, Android OS is causing too much battery drain.
Nothing is running and even then battery is discharging rapidly.
Before that, I used to enjoy 40-48 hours of battery at normal use(only calls & sms).
The screenshot is attatched as a proof...
Please somebody help..
And please forgive me if a thread on this topic already exists, coz I've short time and I m really worried about it.

Download BetterBatteryStats from here (there is a thread), and charge your phone fully, choose kernel wakelocks and when phone is unplugged. When the phone has filly discharged, look at what is causing wakelocks (preventing phone from going into deep sleep). Look up wakelocks on Google and solve problems.

first of all, i dont think that this i anyhow abnormal - since you are using sammy rom, 15% for almost 8 hours gives you 48 hours time between charging.
in settings/battery you should tap the field with uptime, and you will get info about battery discharging - if there are blue bars showing that device is awake, but screen is off, you are probably experiencing wakelocks; then you should either uninstall recently installed app which could wake your phone, or install betterbatterystats and check what is causing wakelocks.

I've installed Betterbatterystats and it shows...
What does it mean?
Sent from my GT-I9100 using xda app-developers app
that means that you had only 1 kernel wakelock, and it didnt last even 1 second.
go to settings, battery, tap uptime and take a screenshot and post it.

yeah, thats the one. compare "awake" and "screen on" blue vertical lines, every time there is line at awake but screen is off, you have a wakelock (event that wakes up device from deepsleep and causes battery drain).
as i can see there are 5-6 short wakelocks which arent too important. you would have best battery life if you choose not to use sammy roms, but its a different story.

there is no easy solutions... but if you want to get deeper into system tweaking, you must read a lot, root your phone and use different kernels to see which one suits your needs best. i could suggest you resurrection remix rom v2.6.1 as one of the most developed ics roms, since jelly bean roms are still in pre-release stage. also a dorimanx kernel, because its most supported. using above combo, i have great deepsleep with almost 0 wakelocks, and about 5 hours of screen time with heavy usage (opera browser almost all the time, and opera is very cpu intensive browser). battery drain while screen is off is almost obsolete.

It's the stock Samsung rom you should do some reading in the original development section if your interested in rooting and flashing.

Sonetimes while playing games phone was 58 to 60% charged n phone switchd off due to low battery within 10 mins
After i turned it on it showed 1 % n was prgrssvly increasing n reach 27% after 5 hours
If i fully charge the fone it just takes 6 to7 hrz for battery to becone 20 or 30 with no use at all

Wait for his reply before jumping all these premature conclusions. Simple
I already know what is causing his problems, but he has to first post his ROM & kennel details before i can proffer any solution for him.

Battery calibration apps don't work. The s2 calibrates its own battery. You can try to reset fuel gauge chip through extweaks if you are using siyah kernel, but I have not seen a difference when I do that

Hi,
I am using Omega v34 ROM and battery very, very bad. On stock rom I had, at least one full day of usage, but now it is a figt to go through working day (7-9h).
I wiped battery stats following a procedure, but that didn't help at all.
And one more thing TouchWizz is crashing at least 5 times a day.
Sent from my GT-I9300 using xda app-developers app
You would need to provide more information.
Have you check what's draining your battery? (you can find a general list in settings--> battery)
You should also try to use better battery stats and ask on the BBS thread/forum for help there to see what the culprit is.
I have between 8hrs to almost 2 days depending on usage.
It seems like screen is using allmost 40% of battery.
Sent from my GT-I9300 using xda app-developers app
set it to automatic brightness. Also use better battery stats and do a full day or night log and ask for help in their forum to see what might be draining your phone.
Sent from my GT-I9300 using xda app-developers app
As mentioned above, sounds like you might have a wakelock somewhere. You can identify any rogue apps with better battery stats and then uninstall or freeze them. Try using power saving mode, you shouldn't really notice any decrease in performance but your battery life will improve. You should be able to get screen on time off about 3 - 4 hours.

Stop using those apps. They use more battery than they save.

"battery saving" apps are really bad for your phone to begin with. remove that junk first. It's probably one ofnthe culprits keeping your phone awake.
then do the BBS thing I mentioned earlier.

Issues connecting to unsecured wifi hotspots
Using Omega v34 and love it! but when I try to connect to my unsecure wifi at work it won't connect. Please help
There seems to have been quite a lot of discussion regarding issues with battery life on Omega 34, in the Omega thread. Because of battery issues that some people are experiencing, Chris_84 has a suggestion in his FAQ (question 27).
You could try a different kernel. Apparently the Yank kernel is pretty good for battery life (I use Siyah version 1.8.4 with Omega 34 and get brilliant results, but then I don't use my phone that heavily. The Siyah kernel allows you to tweak some settings that help with battery).
Also, a lot of comments in the Omega thread talk about installing BBS (Better Battery Stats, as per the comments by mputtr) and posting the log file into the BBS thread (or even in the Omega thread).

There are lots of ways of saving battery such as disabling sync from Google, Facebook and others, adjust the brightness to your needs instead of using Auto and hold down the home button and delete the apps that you're not using
Also if you root your phone, you can install custom ROMs with bloatware removed and custom kernel

Hello, I do hope this hasn't been answered elsewhere and if it has, please point me in the right direction, that would be much appreciated, I have a samsung galaxy s3 i9300, I have ran various different roms, cm10, pacman, and now ultima rom 12.1 with Persues and Siyah kernel, anyway the issue is. I have tried with both these kernels that I would change the default profile with an app to change the settings. The settings have been changed and set on boot. But the battery change wouldn't change, or it would but after a reboot it would drain just as fast as if settings weren't applied. Or it comes and goes. Any help would be greatly appreciated. (I once got 2 days with Siyah) but never again. I don't sync.. Or have high brightness.

It is abnormal when battery drainage changes when I'm not doing or after a reboot. And battery is high or normal as if no settings are applied. However I'll get the following screenshots and report back tomorrow
