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.

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.

My Tab won't stay asleep. It randomly wakes up for a few seconds (5-10) then goes back to sleep. I can't seem to pin down a rhyme or reason as it doesn't always happen, but it does happen often. My main concern is battery drain. I'm running Task 14 with a boosted theme and stock kernel. I've reflashed the Rom but the issue still exists. Does anybody have any suggestions on what I can try?
Your Not Alone!!
I would like to know also, as I have spotted mine do this too on occasions, anyone got any ideas out there please?
BTW, I am also running a Boosted themed Task14 with Pershoots kernel
I am not sure in this case, but I guess it could be an app you have installed. You should monitor with task manager which tasks are running and switch them off temporary to find out which app cause the problem.

I put both cpu spy and b.b.s. along with watchdog on, and can't seem to spot anything weird. Nothing is hogging a lot of juice, and it has plenty of deep sleep time. When it does a random wake up and I use the TouchWiz task manager it shows no active apps and Watchdog only shows minor things in the background, I'm not familiar with b.b.s. or cpu spy, is there something I should be looking for I am missing? Thanks for trying to help me figure this out.

Thanks for the tip. Yeah I use b00sted's ICS theme. I noticed the other person in this thread with the same problem is also using one of his themes which points in that direction except that I believe they are pretty widely used and tested themes. However I will probably remove it when I get around to reflashing the ROM as I think that's the only way to remove it to see if that solves the issue.
In case anyone was wondering, I think I got the problem figured out. I use the honeybar app to bide my task bar. When I disable it, I no longer see the problem. (it's been a couple of days and I haven't caught it lighting up yet.)

Over the past week since I got the S3 I've been Turing off all the stuff that eats the battery power.... syncs etc.
I noticed that when I leave wifi on overnight that theres alot a wakelocks still showing up in the graph. BBS shows connectivityService and activitymanager as top two wakelocks of about 15 mins each.
I can't find out what is causing these wakelocks.
When I turn wifi off, the drain goes down to about 1.2% per hour according to battery monitor widget.
Can anyone once and for all help me get rid of all these wakelocks so that the phone is in deep sleep when it's meant to be? I even turn wifi off during sleep policy.
Thanks.

Just needed the first page of your wakelocks. Kernel wakelock can be found from the drop down menu when you hit partial wakelocks. Also use cpu spy to check whether your phone is properly going into deep sleep.
Normal procedure for me when trying to fix a wakelock:
1. Identify wakelocks with the highest up time
2. google the wakelock names because someone else has probably come across the same problem.
You can rule out rom issues because you're running stock with cf root kernel
Also I noticed AudioOut_1- a fix for that wakelock is usually turning off button sounds(not volume!) and in some cases the haptic feedback as well
If you don't mind me asking, what's that frog icon in your status bar?

I take it I can use titanium pro to back up and then restore all my apps after wipe? How do I go about restoring on the data from selective apps?
I've been using autostarts since last night and I find it excellent.
One question regarding it....how come when I've stuff like Google+ and Game hub frozen in titanium, it keeps showing up in autostarts(and set to start up at certain event changes...even though its frozen)??
thanks for help so far.
No problem. I don't know why the frozen apps show up in the other lists. I usually just limit the apps in the 'after startup' list and leave the rest alone. I normally use titanium to remove them completely.
As for individual data restoration, you can click individual apps in titanium and restore their data. Also check out your Samsung battery stats and see if cell standby is eating up your battery(it's a problem for me but yours might be more serious)

Well I don't think cell standby is a problem for me. I did a little experiment this morning.
Battery was 100% charged, so I unplugged it, turned off wifi and mobile data and let it rest for 3 hours.
Came back and saw that zero drain had occurred and that the battery was still at 99%(which it goes to straight away when you take off charge as you know).
I also had zero wakelocks as the phone was in a true deep sleep.
So I'm still in the position of trying to locate the cause of my wakelocks when either wifi or mobile data is on!
Could these wakelocks be from the wifi/mobile data just searching for a signal? I've tried to weed out any possible apps causing wakelocks when the internet is on but still cannot find the problem.
Well if you you've narrowed it down to your wifi/data problem, try flashing a different modem(possibly one of the newer ones)

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.

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.

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

It seems that Android OS is killing some of your battery life, this usually only happens when you flash a custom ROM, Id suggest finding out what is killing your battery, download an app called wakelock detector, itll show whats using what
Also, the Greenify app is amazing, it wont let any app you chose to run unless you click it.
You could try turning on your power saving setting, itll slow the phone right down ( thats why i hate touchwiz ) but itll give you an extra 30 minutes of screen on time
Theres always custom Roms and kernels too, Ive got the Illusion Rom which ate up the battery for a day ( every new ROM does this ) and then applied the Googy Max kernel, Im running on 800 mhz with undervolting and still silky smooth
Also, try disabling Google services/ sync and disable Google now, for some reasons they seem to be the issue in most cases
