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 blinky@cyanogenmod #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.
