Hi All,
There are a few posts already about a lack of deep sleep, but most of these are whining threads, without any attempt at trying to figure out what's happening.
So...
Recently, my phone started using battery more than usual (no change to kernel or ROM). I've checked battery stats and advanced battery stats, and it appears that the google location service is preventing my phone from sleeping.
I'm taking a punt that this is an issue with the latest update to google maps and/or latitude.
Is anyone else having this issue just in the last few days, and what investigation have you done...
Please do not post your deep sleep complaints and ask for help in this thread. Only post input to a solution...
I've just force closed maps, hoping something changes - I will update soon enough.
Seems it might be the latest update for Music Timer Widget...
Do not install this app, as it constantly tracks your location, and also prevents deep sleep... Basic malware hidden in an otherwise useful app.
same happened to me and i found out GPS turned on itself and if you are lucky (like me) a google pop up appears which asks for your location if not selected anything than it turns on problem solved for me dont know about you
Hi
Try turning off "background data" and in "my locations" turn off "use wireless networks", then reboot and turn them back on. It worked for me.
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.

Hello everyone. I am facing a problem since more than a month ago which is that if I turn on fast dormancy in my phone, the GCMService (Google Cloud Messaging service) causes a lot of multipdp kernel wakelocks and my phone cannot enter into deep sleep. This thing shouldn't be a problem but I have these ones. If I use an AOSP lollipop rom (to which I want to change) I cannot disable fast dormancy and if I disable the GCMService I cannot receive any notification message (e-mail, whatsapp, etc.), which for me are important, at least e-mail. Meanwhile I have a back-to-n00t based rom, in which fast dormancy toggle works.
I will now write a summary of the things I tried and how I realize that GCMServive was driving me crazy. First of all I used BetterBatteryStats to figure out what was going on behind Android OS battery usage and I saw a lot of multipdp wakelocks (arround 30% of total wakelocks and just 30% of deep sleep) under kernel wakelock tab. I did a search and I saw that it is related with fast dormancy. So I tried to disable with all the methods I could find on internet:
-Using Fast dormancy toggle for I9300 app (Play store link: https://play.google.com/store/apps/details?id=com.gokhanmoral.fastdormancytoggle.i9300 ). Worked on stock roms, not working either in CM11 nor CM 12.1.
-Using Fast dormancy toggle for I9100 app (xda thead: http://forum.xda-developers.com/galaxy-s2/themes-apps/fast-dormancy-toggle-app-version-1-5-t2647015 ). Not working on CM11. On CM 12.1 I couldn't connect anymore to the 3G network.
-Manually editing the "nwk_info.db" file. No luck.
-Editing build.prop with "ril.fast.dormancy.rule=0 and ro.config.hw_fast_dormancy=0". Bootloop on CM11 and it is not maintained anymore on CM 12+ roms, as I read here: http://forum.xda-developers.com/showpost.php?p=60511737&postcount=13426
-Using the code *#9900# with phone keyboard. Just available on stock based roms.
-Different modems and kernels. No succeed.
After all these trials I started to freeze apps and when I froze Google Play Services I could get a 93% of deep sleep and just 1% of multipdp kernel wakelock. So it was clear what was causing the wakelocks. Then I started to disable the services running in the app and when I disabled GCMService I got again a 90% of deep sleep and 1% of multipdp wakelock. But there were no e-mail notifications anymore. So I am blocked here.
Does anyone know how to reduce the activity of GCMService and still be able to receive e-mail notifications but no having wakelocks? If it is possible I prefer a solution not involving xposed.
Thanks a lot in advance.
And I want to acknowledge in advance all the rom developers who created the roms I used and the developers and researches who made the apps and procedures I used here.
More info:
Test environment: WiFi off, GPS off, Bluetooth and NFC off. Just 3G mobile data on with full bars signal and fast dormancy on.
Roms I used: Blekota Note 4, official Cyanogenmod 11, and ArchiDroid 3.1.3.
Edit: Greenifying all GCM apps doesn't work either.
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?
