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

Hi @all,
since i switched from samsung stock rom to CM 10.1 (M3) there is a high battery drain when the phone is running on standby.
To be sure i'm getting nearly "comparable" results, i flashed both roms completly clean without any additional apps. Google services/syncs switched off, mobile data disabled.
With the samsung stock rom the battery lasts for about 3,5 days in standby. With CM10 the battery is drained after 1,5 days. 12 hours after charging BetteryBatteryStats shows a high number (~20000) of kernel wakelocks for the type "wlan_ctrl_wake" (NOT wlan_rx_wake). As far as i can see, there is no connection to any app keeping the phone from entering deepsleep. However, i only have a deepsleep rate of about 70%. Nothing suspicious in partial wakelocks.
Regarding the battery drain topic, there are many hints on google now, latitude, Gtalk and so on. Already tried those. There's no need to change the wifi settings, because on samsung stock rom everything works fine using the same settings (just about 40 wlan_ctrl_wakes within 12 hours). I'm using Fritzbox 7170 as wifi ap. Some people mentioned multicast/broadcast packages may be a reason for high wifi wakelocks. I traced the network, but nothing of the sort occurs.
Any ideas?
Thank you
Wakelock detector will link the wakelocks to the specific apps
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
Greetings,
I had been using my Xperia Neo V with Cyanogenmod 10 (10-20130519-NIGHTLY-haida) for the last 2 months. It was all ponies and rainbows for me for the first 6-7 weeks.
Issue:
Now I'm facing with a random and ridiculous overnight battery drain issue since a week ago. Ridiculousness here is being referred to the amount of the drain (almost 60% overnight) and to the fact that there's no particular change of use of the phone by me,comparing with the days before. As you can see in the screenshots, the main actor here is "Operating System". I don't really know what this drain is related to, so I was not able to do comparisons of use.
Facts:
-Mobile Data was active but only at 2G
-Location services were off
-Bluetooth and all other possible signals were off
-No active apps, all were hibernated with Greenify
What might be the reason of this problem and what would you advice me to try?
Thanks in advance.
what kernel are you using? overclocked?
maybe you can try re-flash the rom
60% overnight is way high battery drain
You should try to see a pattern. Does it happen after specific usage "ritual" or just purely random?
It may be kernel bug/core system bug. Try dumping dmesg and logcat when it happen next.
I would start by trying to flash other kernel.
Install BetterBatteryStats (ther's an SDA thread); It will give you better info of what is draining your battery. In addition to that, you can post your logs in the thread (BBS thread) and they will provide better help.
Good luck
Edit: here's the link http://forum.xda-developers.com/showthread.php?t=1179809
Install wakelock detector app uninstall those... Try greenify too
Firstly we have to know what kernel are you using...
2.6.32.9 or 3.x.x version?
Hi there all, thank you for replies, and here are some extra info;
Fresh facts:
- Kernel: 2.6.32.9-FXP [email protected] #1
- Not overclocked
New observations:
So far I don't see any pattern as to what could possibly be the reason for this issue.
The last time I faced with this, the phone was fully charged and on 2G mode I left it on my desk (my wi-fi router was located next to it, keep it in mind so that it might be a clue coinciding with the BetterBattery logs I will reveal next) and after 3 hours, when I went to check if there were any calls, nearly 30% was drained. Comparing with the initial drain issue (which is a 60'ish% drain overnight) I can say it's the same issue within a proportionate period.
Well takin' a quick look at the BetterBatteryStatus report, drain was mainly caused by some wake thingy called "rx_wake". I don't really know much about all these wake calls in Android system but I googled it and reached to a brief conclusion that it's somehow related with Wi-fi connection. So I'm suspicious that maybe my Android system is perpetually sending wake calls related to a Wi-fi signal even when the Wi-fi mode is off on my phone (only relation I could make here is that I left the phone next to my wi-fi router)
I attach the screenshot and BetterBatteryStatus logs to this post, thanks in advance for your further comments.
Further comments, anyone?
Post the logs in BBS thread. There people has more knowledge and they can help you.
Issue Solved on Galaxy S - Will fit all I assume
Hi
I face the same issue from the day I install the ROM (CM 10.1.2)
I browse the Internet and found the issue
The issue is Wi-Fi and mobile network location
When it is on in this version it turn on the Wi-Fi not only on GPS request and No GPS status
You need to shout it down and issue solved
To change this setting:
System Settings -> Location access and disable the "Wi-Fi mobile network location"

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.
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?
