Hi,
I have been on CM since January. The battery drains like hell, I tried the different solutions I've read on the forum (cache wiping, dalvik cache wiping, force closing before uninstalling.. etc), I even wiped my phone completely (as new, no data at all) but with always the same result
Sometimes I have less than 1h of screen usage with no wifi and no GPS and it dies after 17h. Always the same guys comming "Android OS" and "Android System". Google+ upload is wifi-only, latitude was disabled few minutes after installing gapps. No Facebook, Twitter, nothing!
I've attached a batterystat log. That day (two days ago) I was even runing the phone in 2G mode just to see if it will change anything.
I'm running CM10.1-20130627-Nightly-i9300 with a baseband i9300XXEMA5
Thank you in advance for you rtime

Hi again,
since my last post (http://forum.xda-developers.com/showthread.php?t=2048671) in the general Android section did not lead to any solution I ask you for help in this section again.
First of all, I spent hours, and really some hours, looking for solutions in this forum, other forums, etc. and did not find any solution for my problem.
Whatever I do about my I9300 I'm loosing about 2-3% per hour in total standby. What I did already:
- Changed the ROM from Stock to CM10
- Changed the kernel from Stock to Franco
- Did several Factory resets
- Disabled all possible funktions (GPS, Network Location Services, Autosync, etc...)
So now I have my I9300 in front of me, just did a factory reset, Wifi and 3G on, no apps installed, no widgets, franco kernel installed and it's loosing 3% battery per hour. In the android battery stats, it's Andoird OS what is consuming 75% of power. The 3G signal is not perfect but not bad neither.
Betterbatterystats is not installed yet but I had that before I did the factory resets and there was always nothing really eye-catching besides the NetworkLocationLocator wich had a lot of partial wakelocks. Judging by what the android battery stat says, I have no problem with the system staying awake after the factory reset...
Any ideas what could be the problem ?
Thanks a lot,
Mika
So I've had cm7.2 on my phone for a couple of months and it's driving me crazy with some of the issues it's been having. The first one is battery life. Back when I had stock blur, I could go all day on my phone and still have 70-80% by the end of the day with moderate usage. With cm7, I'm getting around 50% just from it being idle. One of the reasons I installed a custom rom in the first place was to get better battery life out of my phone. The next issue has to do with wifi and data. A lot of the times I turn on my phone from sleep, it'll take a minute or two to connect to the wifi. Sometimes it won't even do that which is a little frustrating since the phone will try to use a data signal and nothing will happen because it's still trying to connect to wifi. So that ends up in me burning through data with nothing happening. The last thing that's been occuring and is really annoying are the random reboots. My phone usually does it once every two days or sometimes like today, a couple times a day.
Are there any fixes for these? So far I'm finding that stock blur has been way more stable than the roms I've tried out so far. Don't know if it's a issue specific to the atrix or if it's pretty much like that with other phones as well.
wifi issue can be remedied by going to wireless networks>wifi>advanced>and tick the 'always on' box, that should sort you out.
Have you installed the 'bluesleep' fix? it's a zip file so you can install it via clockwordmod (it puts your phone into deep sleep when not being used and should help you with battery usage). You'll also need to install cpu spy which helps with the bluesleep fix.
Random reboots can be caused by lots of things (apps,unstable roms ect). I would reinstall CM7.2 again (without a data wipe so you wont lose anything) and see if that helps. I would however wipe dalvik cache. If it carries on I would do a full system wipe and reinstall the rom of choice again.
How do I get the bluesleep fix? I remember that being a problem on cm10, but I never knew it was an issue for cm7.2
Alright and what does the dalvik cache store exactly?
I've put the bluesleep zip I use on here for you (i'm on 7.2) . Also, a link for CPU Spy https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en
Dalvik cache... 'dalvik cache is a program cache area for the program dalvik. Dalvik is a java based virtual machine that is the bases for running your programs (the ones that have the .apk extension). In order to make access times faster (because there's not JIT (just in time) compiler installed by default), the dalvik-cache is the result of dalvik doing a optimization of the running program. Sounds confusing. It's similar to the prefetch files in Windows.'
I would wipe dalvik and see if it helps the reboot issues you are having.:good:
Gotcha. I'll try it out and let you know how it works out.
So I've been using the phone for a couple weeks with the fix and for the first week or two the battery life improved and then for some reason over the past week or so became bad again. I checked my battery stats and it may be because of the wi-fi, but I'm not sure.

Is bluesleep still working? Sometimes you just need to re-flash it. Also, have a look around on here for wifi issues - there's been a few questions about disabling/deleting wifi so you might find some help. And!! try wiping Dalvik (again!) And!! think about reflashing rom ect as sometimes a clean install will help.:good:
Hi,
I can’t say I’m impressed at all with the SGS2 battery life running CM11 M7 (KitKat 4.4.2). Quite often the battery won’t last through the day (luckily I can charge it at work, otherwise it wouldn’t even be bearable as a phone).
My crappy Sony Xperia J (JB) I had for a couple of weeks as a replacement could easily reach the end of the day with 70% charge still left when I plugged it in at night.
Android battery stats always show Android System and Android OS as the main offenders (around 20% - 25% each), above Screen usage, Voice calls, Mobile standby...
BetterBatteryStats tells me the phone is in the Deep Sleep most of the time, but also that it is awake (mostly at 200 MHz) quite a lot of time as well.
Here’s what I have already tried:
Disabled location services
Disabled Google Now
Disabled Google+ Auto-backup
Opt out of interest-based ads
Disabled back up data to Google servers
Disabled “Android Device Manager” as Device Administrator
Uninstalled all updates to Google Play Services
Disabled automatic updates from the Play Store
Disabled Mobile Data Limit
Disabled Automatic Date/Time updating
Uninstalled Lookout Antivirus
Uninstalled Viber
Uninstalled Skype
Rebooting the phone before connecting the charger
Rebooting the phone immediately after disconnecting the charger
I really don’t want to perform a factory reset specially since I have read some other comments by Galaxy S5 and Nexus 5 owners (KitKat 4.4.2) saying it didn’t work…
So what exactly is going on here?
Thanks!
Sorry

Sorry I cannot help you, however, I am also contemplating installing cm11 on my sgs2 i9100.
I wanted to ask you if you phone came with android version 2 installed on it? (maybe in that case the problem is incapable hardware)
Mine came with 2.3.4 and i do not want to face the same problem as you are now (sorry).
Thanks
It is normal, that non-stock-based roms consume more power because Samsung haven't open-sourced all drivers. And Kitkat drains more than Jellybean. Try Slimsaber Reborn. It has a decent battery life, an very acitve developer, and is nicely customizable.
Any luck?

Hi MegaShark!
I have almost the same issue you have, my device never go to deep sleep... (by "never" I mean 1 minute deep sleep and 1 hour 200MHz)
After months trying, getting help from Better Battery Status thread, flashing, freezing, going crazy, I commited suicide (flashed stock ROM), but it is driving me mad.
The last try I did was with SlimSaber Reborn (Android 4.3.1), but no luck also.
Installed "Unbounce", prevented nlp wakelock, prevented safe alarms and nothing, it only gets worse...
All I get is my device always warm (always running at minimum of 200MHz) and more than 10% battery drain per hour.
Have you found out what is the problem with our S2 on custom ROMs?
Thank you!
First of all, I would advise you to update your rom. CM11 M7 is old now and is filled with bugs (along with versions around that). Update to CM11 M11 Snapshot which will most likely fix many of the problems you are facing but you will need to do a full wipe (factory reset, wipe dalvik and cache partitions). So sorry, the only way to fix is to wipe your data and update.
Will try!

I remember to have hope until CM11 M9... But I'll give M11 a try and report back here!
Drain NOT related to any of the CM version
I have been facing battery draining problem in my sgs2 (i9100) just after installing CM 11.
Then I tried NeatROM without any Luck!
Every time i cleaned data, cache and dalvik to be sure...
at the end I moved back to Stock ROM - everything fine there...
but again then I decided to have just root and custom recovery installed... which required me to Flash Jeboo Kernel v1.2a (which comes with CWM based recovery 6.0.2.7 preloaded)
then it started same problems again... overheating - battery draining ...
It clearly look like ... the battery draining/overheating problem is because of .... Kernel AND/OR CWM 6.XXX
I think, if one want to install CM 11 in sgs2, after installing ROM, he/she need to flash it with some other kernel.
If anybody have tried some other kernel, which doesn't cause battery draining/overheating problem, then pls post here so that other can also try...
Confused

pankhawala, I installed the last available SlimSaber Reborn (4.3) (here: http://forum.xda-developers.com/gal...rivatives/rom-slimsaber-reborn-i9100-t2811657) because o lots of positive feedback on this ROM.
It is really a very nice ROM, but my battery drain problem persisted, I was losing more than 10%/hour in idle.
I just tried to "live with it" and after some weeks it mysteriously gone away.
I was happy for a few days and it went back again.
Now, it has been since this Sunday that it is gone again.
I'm being able to have a very acceptable battery life, very good deep sleep times and less than 4%/h when idle (screen off).
I didn't changed anything and it just got better by itself.
I'm sure it will start to drain again, just don't know when or what is triggering it.
My last hope is that when new Lollipop ROMs start coming out for our S2, some holy developer figure out this problem or that the problem is simply gone.
Hello everyone!!
A couple months ago I decided to install CM11 on my phone because its performance with the stock ROM was absolute garbage. When I did, everything was exceptional until a couple weeks ago when I started having severe battery draining issues and today was just THE worst day of all.
I charged my phone overnight and I disconnected it from the charger at exactly 6am (when I woke up to go work) only to find out that at 2pm (when I finished my shift) the battery was at 0%. Since I was at work my phone usage was pretty much 0%, including only a couple of texts and that is it.
Now, some time ago I was diggin' around some forums and apparently this happened because Google Play Services were draining 60-80% of my battery overtime. A user in another forum (Calkulin, XDA Developers) posted some modded Google Play Services that would fix the issue, it worked perfectly until Google was updated again and the problem came back. That same user posted an updated version of his modded G.P.S. but unfortunately this time it didn't fix the problem.
I also found an app that would stop acquiring the wakelock causing the issue called Wakelock Terminator but it didn't work either and I am currently using it since I don't know what else to do. I'm really desperate to solve this issue because I depend on my phone to do all sorts of things.
Can I please get some help regarding this issue? This is very very urgent to me.
Best regards,
Carlos M.
First download latest cm11 KitKat gapps package and flash it. Delete your Gmail account, wipe cache and dalvik in recovery, wipe cache of Google Framework and Google Play services. Set your Gmail account, launch Play Store, minimize it by pressing home button and wait minute or two. Restart your phone.
If wakeloks persist launch privacy settings and from advanced menu of system apps disable events in those services which causing most wakeloks.
You can also disable wifi scanning from wifi advanced settings when your wireless connection is off.

I just got this phone about a week ago and right away I noticed that battery life was very low. I tried doing some charge cycles and I even got a brand new Anker battery but nothing changed. I looked at the battery usage and the graph is just steadily dropping with very minimal screen usage. I have turned off background syncing on everything and I disabled notifications on most of my apps (all but Facebook and Instagram) and still the battery goes dead in under one day of standby. Looking at battery usage I noticed that Android OS,Android system, and Google play services are pretty high on the percentage (I do have auto updates disabled though). I know the battery shouldn't be dropping from one day of standby. I've also checked some other posts where people say to turn off auto brightness and notifications and I've tried all of that to no avail. Also on the battery graph the scene time is of most of the time, but the puzzling part is that the awake time is only dotted a few times, no large bars that might be huge background processes. And speaking of background processes, most of my running apps say they've been on since the time my phone had turned on (not sure why). Please help me out on how I can fix this, I can post screen shots if needed
Wipe it and flash latest firmware with Odin, disable all the bloat.

Thanks! I'm trying that right now, I'll tell you if it worked
It did not work Could this be a faulty device? Here is a screenshot of one hour of usage after factory reseting. As you can see on the running apps (my phone was on for about 8 mins in the picture) there are a few processes that stay running from startup and never stop.
p.s. I also went disabled all running apps that were possible and that didn't look important (clock widgets, SNS, Stock Daemon, etc.)
