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?

I just registered, so I can't ask this directly to the developer, but hopefully someone can help me out. I flashed the ICS *Passion* 9.2 beta after reading up on it and seeing all the rave reviews about it. It has been a couple days with a few charge cycles completed and my battery life is still in the hole. Does anybody have any idea why my battery life is so bad? I hardly use it, just to text a bit and browse the internet occasionally. I saw quite a few posts in it with people achieving 12-17 hours battery life with moderate use, and yet I can only manage 6 with light use. The battery menu shows the screen using quite a bit of battery, which is strange, because I have the screen off with the exception of a quick text. Help?

I have similar battery use issues. I believe you have to have it fully charged then wipe your battery stats in the Clockwork Rom Manager menu under advanced. Fully charge again and repeat the process several times. You are probably aware but if dataswitch or wi-fi is running while not using, it will drain bigtime.

Wrong about last part.
I run wifi 24/7 and get 20+ hours light use of course.
I'll give you some of my settings I did to make it like this when I get to a computer I don't like typing long things on phone.
Sent from my SGH-T959 using xda premium
There are some apps and explanations for download in my Battery Guide, post 3, that may help with this too.
Listen to Rider though. He's been on ICS since the beginning. Send some if those settings my way and ill put them in the guide if you want/don't mind.
HNY buddy.
Ok, i will list a few things I ALWAYS do on ICS right after flashing.
Settings> Display > Brightness to lowest ( i don't like the high brightness it hurts my eyes if i need it i turn it up) My Screen display time is set to 2 minutes (i don't think it matters unless if you just turn your screen on and leave it there)
Accounts and Sync > Sync everything right after flash and then disable syncing of Google Photos and Calendar (unless if absolutely necessary)
Also if you sync things like Gmail and what not, try to set the sync time 1 hour + mines set at a hour.
I also use Titanium Backup PRO to freeze DRM protect- , Email, and email exchange ( i only use GMAIL so i don't need another app taking any space) if you don't use gmail, freeze it.
I don't like using GPS because I know the places I go to. I know the roads near me etc. GPS shouldn't be THAT big of a problem if you remember to turn it off after using.
Settings> Location> all of mine are unchecked, if you do use GPS frequently then check the ones necessary. I don't like Google knowing where I live, it does no good just wastes a little bit more battery.
I use SETCPU(paid) you can use Voltage Control (free) and change your frequencies to minimum: 100 max: 1000 and then menu > set on boot or something similar. If you don't set it on boot, right after a reboot its going to change.
Thats basically all the things i do at a fresh rom flash. I might update this post if I miss something.
I love Android.
I think the customization is great, and since v4 it's smoother and feels more responsive.
There are LOTS of apps and it's better than iOS.
But i'm sick of the battery issues.
I've always loved trying new features, ROMs, apps, hacks and whatever.
I now have SGS3 and it's my third android device, and i've installed ROMs dozens of times, even on my friends' devices.
One thing that always kept me alert is the battery life - the maximum I can get from my battery is around 30 hours with my usage - 1/5-2 hours of screen, ~45 minutes talk, lots of standby.
But every now and then, my girlfriend, my dad, my aunt or my friend ask me 'why does my battery drain so fast?'
Sometimes its google maps.
Sometimes its mediaserver/media scanner
Sometimes - and only I can see it cause they are not familiar with tools like BBS, it's gsf (Google Services Framework).
The point is, when you have an Android device, you need to check the battery stats every now and then to make sure nothing is unusually heavy on the battery.
I am currently experimenting with ParanoidAndroid and AOKP, which are faster and more responsive than omega/stock.
Yesterday i went to sleep (6 hours) with 25% battery (after it lasted 15 hours) and I turned off the data connection and the wireless connection.
I woke up after 6 hours (lucky..) and I saw my phone if off. after I connected it to the charger and turned it on I saw mediaserver decided to wake up in the middle of the night, after It almost did nothing during the day, and worked for 5.5 hours until the battery died!
Today I unplugged my phone and in 1 hour of standby 10% of the battery were gone, I checked what happened using BBS and saw gsf again (that GTALK_SYNC whatever wakelock) was draining battery, after I thought I fixed it yesterday when I disabled app data and browser sync in the google account sync options). I rebooted and now it seems ok again, the phone is back to ~70-80-% sleep.
I want to emphasize that I don't like all the stupid battery tips that tell me to castrate my phone:
turn off wifi when it's not needed, turn down the brightness, lower the screen timeout, disable sync (wtf? but its a smart phone, I WANT push notifications!) and that sort of things.
I KNOW I can get >24hours of battery without disabling the basic features of my phone.
And the draining battery processes that I mentioned earlier can suddenly appear even in a stock ROM, so I don't think it's PA or AOKP's fault.
What I want is that google will finally build a supervisor entity that will check what causes an unusual battery drain, check if it makes sense, and disable that cause!
It's absurd that google maps application comes with default 'enable location reporting' that constantly drains your battery and for what?? google maps doesn't run in the foreground, why the hell will I want that background location reporting draining my battery? and if so, why do you put this option enabled BY DEFAULT? The average user doesn't know this sort of stuff, and get only 10 hours of battery out of a device that should ideally provide ~30 hours!!!
Just wanted to let it out of my system...
And to get useful battery tips if any...
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.
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

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.)
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
