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.

Ok, this has gone past creepy
I got myself I9300, did all the necessary:
Root, ODIN > Philz, wipe, install rom
I installed PA for i9300, which was nice but battery drain was immediate problem so I just thought it was a bad/unfinished ROM. I then installed Resurrection remix which seemed like really neat and complete ROM only to experience the SAME problem - standby battery drain.
I then started searching for the problem cause. BetterBatteryStats says:
partial wakelocks -
SystemUpdateService on par with Awake. it is ALWAYS on
googled it, here is the problem:
People reporting it on 4.3, making constant wakelock, disallowing the phone to go in deep sleep once it is locked. And it was actually fixed in 4.4 CM and CM based roms (resurrection is one of them) but mine is running still.
I then started searching for the solutions, even though my OS version shouldnt do that. One of them says -
You should disable the service via apps "service diasble" or "Autorun Manager" from Play store in order to stop it. So I download both and the service is actually unticked. Shouldnt run at all. but it is still there destroying my battery. Next thing I found on CM forums says:
"wakelock is disabled by devs so that users wont experience constant OTA updates, and while it is disabled, it still runs (nice logic over here) and enabling it stops the wakelocks"
I then tick it to "enable" via those mentioned apps, but the wakelocks are STILL there, phone wont go to Deep Sleep
Extremely annoyed, I went to Settings>Apps>All and disabled the whole "Google services framework" which containts "SystemUpdateService" and there you go -
it still runs, wakelock on par with awake time ....
Is this God-mode service, is this some magic ? What the F is going on, and why do I even experience this when the problem was solved in 4.4 .. ? Please help me.
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.)
Hi,
I am very new to this and I created this account in the hope that someone will be able to help me. Please be gentle with me and explain things like I'm five.
I recently installed CM13 on to my Galaxy S2 and the battery drain is ridiculous. For example, it was fully charged fifty minutes ago but it is now at 89% - and for a majority of that time it has been in aeroplane mode. I am using Wi-Fi only when not in aeroplane mode and while this hastens the battery drain, it's not by a huge percentage.
My phones stats are:
Android version: 6.0.1
CyanogenMod version: 13.0-20160404-NIGHTLY-i9100
Kernel version: 3.0.101-CM-g3419d27 [email protected] #1
GAPPS: BaNkS-Dynamic-GApps-6.x.x-10-20-15
TWRP: IsoRec_TWRP_3.0.0-0_i9100
Things I have tried:
Using privacy guard to stop Google Play Store and various other apps from starting on boot and staying awake.
Setting the screen brightness level to the absolute minimum.
Setting the screen to go to sleep after 15 seconds inactivity.
Turning off Wi-Fi scanning.
Setting my e-mail pushes to one hour instead of instantly (which I especially hate).
Turning off voice recognition.
Setting location mode to battery saving.
Installing Advanced Task Killer, Greenify and/or DU Battery Saver.
Recalibrating the (new) battery - manually and with the battery calibration app.
Resetting network settings.
And various other things that I can't recall right now.
I recently installed GSam Battery Monitor, but it's not telling me much at the moment - just that the screen uses 64% and apps use 36%, and the average battery life per complete charge is at 7h 13m (3h 20min active).
If I go to settings > battery, it's telling me even less - the screen has used 4%, CyanogenMod System uses 2%.
I've read on other forums that installing a different kernel will improve it, but others have said it won't make any difference. Either way, I have no idea where to get the kernel from. I'm starting to think I must have installed something very wrong when the battery life on my phone won't even last eight hours. I have spent the past couple of days browsing to try and find out what I can do, and I think I'm about to go cross eyed.
Can anyone please help? Please remember that I am a complete newcomer to this so I may be asking some really stupid questions.
Thank you in advance for any help offered. I really don't want to go back to my 3GS now.
Hey,
I'm also on CM13 and also have battery drain, since Android 6 is really heavy, but definitely not as bad as you.
One thing you else could try is the app "BetterBatteryStats" which is available for free on XDA - just search. In my opinion it's the best available app for battery statistics. You can check out which app is keeping your device awake at standby.
But in your case, as you already tried a lot, I recommend to simply do a clean install of CM again. Really looks like there were little errors while flashing, or the Rom's zip file got somehow corrupted at the download. So download ROM and Gapps again, go to recovery, wipe /system, /data, /cache and reflash ROM and Gapps. Perhaps use another Gapps package than you used before. Also consider choosing the littlest available one. Maybe the issue will be gone then. Really hope this helps somehow.
Was I gentle enough?
Hello forum,
background info:
I have a rare Pansonic Android 5.0.2 phone (DMC-CM1) with an excellent camera, what is the reason why I want to keep this device.
There are NO custom roms available and no info about key combinations on how to get into stock recovery mode. I can go there with adb of course.
I found a key combination to get into fastboot, but Wiping cache/data to reset the device apparently did nothing, even if wating for hours. It seems as well as if Panasonic tampered with the stock bootloader :/ This is why I had to send it to service (adb was not enabled before).
They reflashed the device with 4.4.4 and I installed the updates to 5.0.2 OTA. Everything seemed fine until...
present problem:
...now I have a strange battery drain. Bevor I sent it it, I had about 2-3 days usage time with average usage, a little messageing, a few fotos. I do not use the phone much.
Now I get a maximum of around 16-20 hours out of it while it is just resting on the table. It also gets warm.
what have I done so far:
- I rooted the device and installed better battery stats from the forum here. It shows around 8-10% usage per hour. Before the problem showed, I had 1-2% usage.
- I uninstalled EVERY own installed app and even booted into safe mode -> same problem
- I disabled all google app packages -> same problem, but improved it a little
When I check the battery via android settings, it is telling me that "android-system" is using >20% of the battery. In active apps I can see this app is running the fast dormancy service. When I kill this service and force the complete app to stop, it gets _a little_ better, around 5-6% usage.
I recently killed forced stop on all services that where not qualcom or seemed essential to me and disables wifi and bluetooth and over night usage dropped to <1%/h, which seemed the problem could lie somewhere with services.
However using adb shell and pulling "top" info, I dont see a process using much CPU.
What else have I noticed, which might be unrelated:
-After charging I see a 100% wakelock from qpnp-charger, that disappears only after rebooting. Might indicate that something with qualcom is "wrong".
-I set wifi to be _never_ be running in sleep mode. Better battery stats is telling me, that wifi is 100% of the time running, even if I can see the symbol for wifi is not showing and comes up a few seconds after I wake the phone
You can see, I might need help on how to identify the problem here.
Any hints, tips, advice?
Please excuse my "messy" english, it is not my native language.
regards
Stefan
