Hey guys, I tried both cm9 nightly and rc2 prefinal but both are giving me lot of wakelocks and phone drains about 25 % in 6 hrs standby, better battery status showed 5 hrs partial wakelock by google event log service, I came from cm7 and did a full wipe before ICS, please help me, tell me if I need to change any setting or is this problem faced by you people also ?
Did you tested battery calibration? I make it every rom change and by now it become always better. But indeed I notified also that ICS is more battery-expensive.
Ics will drain battery .. else try djnoxd ics kernel , its having better battery life than stock kernel
Regarding wake locks, I am not having any problems.. check with your installed apps.
battery calibration is useless, the truth is that you don't need to do it unless you get wrong battery readings

Hi all,
Since I started using Lite'ning ROM v2.1 I noticed that my battery was draining very fast.
I went to my battery use and I saw that "Android system"was using 44% of my battery. Wake time is almost 6 hours...
Is this a known bug or is there a solution to this?
Battery drain start with the Better Battery Stats app and thread .

If the rom you are using is not yet a fully stable rom then it could have battery drain problems, although battery drain is usally how you use your phone. Look what apps are running when you notice your battery running down fast, as it could be one of those.
When im at work i actually only use whatsapp, and sometimes facebook while im on break. But my WiFi is off all the time then, only whatsapp and battery monitor were active. With 2.3.4 this wasn't a problem and my battery would be 60% when i came home...
Either google wakelocks and how to pin-point them, or wipe and install NO apps afterwards, run it for a day and if the same problem go to another rom till it's more stable .
What works fine in 2.3.4 has no garuntee's that it will work an experimental ICS build of any sort.
i have similar problem. my galaxy is on wanamlite 9.6, which base on LP7. after 5 hours of not intensive using, i have 65% battery left, android OS use 68% of this battery, most of time my wi-fi is off. when is on, drain battery very fast, over night even up to 20%. when i was on ginger bread it took around 6% - 8% with data and wi-fi on.

Do you have many widgets?
Especially Beautiful Widgets and Fancy Widget (moreover if you activate the meteo forecast) will constantly drain your batter in search for your position. Wifi uses less juice than 3G connections.
Happened to me back at GB 2.3.4. Battery went down to 60% in 3 hours (at the office I'm on G...so even worse cuz the battery compensates for the lack of coverage). After I removed Fancy Widgets from the screen everything went back to normal.
Don't have any widgets as far as I know, only the clock and twitter...
Today battery is know at 26% after 11 hours on battery. Process stil at 39% battery use.
I searched the web and found that there are a lot of users having this problem, especially with the Google Nexus.

For me is same. After 15 h, I have 26% left and 78% of android os
Sent from my GT-I9100 using XDA

Battery drainage for cm7 fxp115
I installed it yesterday and fully charged it
by morning it was at 39% :-\
im postiong the screen shots or bettery battery stats..
Well the battery drainage depends on a lot of things like services running on the background or sync services enabled etc. But you can also try this kernel and see how it goes http://forum.xda-developers.com/showthread.php?t=1549221
I have been testing the 2.7 kernel since yesterday
And sync is off
As You can see ...the battery usage is from Gps location service
and the graph shows that the phone was awake always :-\
Well then shuting down the GPS when it's not needed should lower the battery usage of the rom
Settings>location&security>use gps---off
i already tried it
cant figure out what it is using
Well once again I recommend you to try with the kernel I posted before and well report the issue on the roms original thread as it may be a bug the developer can fix on the next release.
so as im a new user and i can't post in half of the forum, but i've still got this urgent question/ point to ask, here's my question:
i recently moved on the new 1.9.1 ressurection remix rom from the 1.3, and aswell changed my kernel to siyah, now lately my battery drains preety quick (yes i did burn it down to 0% and charged it over to 100% few times), but here's the thing, when once i had issues with screen burning 30%-45% of my battery, now it's lying low on 10%-20% while the real issue now is the "Android OS" which goes as high as 60%-70% of my battery, i've been trying to calibrate the battery and reset battery stats and discharge and recharge couple of times, but this just keeps going on... any way to solve this?

OK! I've read your situation. This is the only thing that I can recommend. Try installing a Gingerbread rom and see if the issue persists. If it does then some of your application could be the culprit behind the battery draining issue. But again, thats just a guess...And if it is one of your applications that is causing the drain then you should install bettebatterystats from this thread:
http://forum.xda-developers.com/showthread.php?t=1179809
Then charge your battery to 100% and try a new calibration method, maybe you haven't heard of it. But if you charge till 100% then take out the battery for exactly 3 minutes and put it back in and power up your phone and use your phone normally as you do and then at 20% or lower go and check betterbatterystats and see what is causing the most of the battery drain.
Have a great day and good luck with the battery drain, hope this helps!!
Did you check the ROM FAQ about battery draining?
Please check it out. There is also an example of making some changes using extweaks which comes installed by default with ICS Resurrection 1.9.1.
Here is the link to FAQ.

i did read about the new method today, but havent had the chance to try it yet.
im not sure if it's a certain application that causes it, but in the battery stats it points out "Android OS", i've seen many galaxy nexus users complain about the same problem, even with stock kernel/roms, and galaxy S2 users that moved from gingerbread to ICS. it's logical that ICS will take more battery because of the control over multiple cpus and all this kind of stuff but im not sure how much it is about that "Android OS".
anyway ill try to have this battery calibration new method once my battery will drain out, and im probably not going to go down to gingerbread again because i already know its not gonna persist because i remmember how my phone behaved on GB and that those 2 systems work completely different and i want to solve the drain per ICS and not solve the issue by downgrading back down to gingerbread.
thank you for your time and help anyway

thanks for the link, i haven't noticed too much i havent done yet, they poiny siyah kernel as one of the 3 good 1s that work well with the rom for better battery, and i am testing different governors, clocks and voltages but there's many options so i can't do it all in an instant so it takes time...
thanks for your help
Well recently I bought the Beast S3.
Now I installed this first Kernel - CF-Root-SGS3-v6.4
And CM9 rom, was working great though there's one problem the damn battery drain is like being raped evey 5-10 mins if not less I loose 1-2% battery.
Now I though it might be the Kernel so I switched to Siyah-s3-v1.5.3-CWM, no go still the same result.
I changed my Rom to CM10, same result.
Here's a Screenie of my device (In Attachments)
Could you help out a little? I've checked and not sure where is the issue, and I understand that super huge screen consumes allot of power but even if I set brightness to 0-25% I get the same result...
Most battery issues are caused by installed user apps. Install Cpu Spy for cpu deep sleep issues and Better Battery Statts for locating apps that show unusual activity`s and drain the battery.

This battery drain percentage looks normal to me.
Sometimes I lose 5% without doing anything, even if I have a perfectly cleaned rom.

My battery seems to drain really quickly on data and last really long with data off.
I had my screen on the lowest brightness for the full day and had data off for most (75%) of the day.
Same Battery draining issue
Hello,
I am having the same issue of battery draining after installing Epinter's CM 10. I am very thankful to Epinter for detail guide and all the links for download of JB 4.1. I love using JB but only one major issue of battery draining. Even after overnight recharging of the battery, it only charges to 78% and not 100%. I am also learning all the settings of JB 4.1 I am looking for task manager to autostop background apps which are consuming battery and preventing my phone to go to sleep.
Members' guidance will be much appreciated.
Thanks.

Try this method. This resets stats and after that it should keep charging to 100%
