[Galaxy S II Q&A, Help & Troubleshooting] Lavin_A:
It's because of the memory management issues in lollipop. It is likely to be fixed in Android 5.1

Battery Draining fast while using 3G data or WiFi

Hi,

I am very much new and not very much familiar with Android development. I use a galaxy s2 i9100 phone. Recently i have been trying CM12 . One small problem for me is the battery stays fine if i am not using 3G data or wifi, but when i start using any one of these it is draining drastically 1% every minute. What could be the cause and how to rectify the issue. Kindly help.

BTW your work is awesome, since we are not getting updates for Galaxy S2 since 4.1.2 version of firmware.

Some FAQ I've been seeing:

Q: What's the best kernel?

A: Honestly it depends. You have to experiment your choices (Apolo/Stock [emoji6] ) to see which suits your needs (BLN? Battery life?) If Apolo doesn't work for you just come back to stock kernel by doing a dirty flash of the zip file.

Q: How to upgrade to CM12 from stock firmware?

A: FIND a CWM kitkat kernel to install over. I don't know if it still boots stock FW, so once it's installed reboot to recovery (power off > boot to recovery) and perform standard installation procedure (also wipe /preload before installing). This method works for me, anyway.

Q: Extraordinary problems!

A: Before posting a question on xda, have you tried the following:

a. Did a clean reinstall of the ROM (wipe /system /data /cache /Dalvik /preload)

b. Did a clean reinstall of the firmware (Odin to stock FW and restarting everything again)

c. Find relevant answers by using the search tool in the threads (very important)

If all steps are done and you still face the problem, ask, but also provide:

Device model/variant (depending on country)

Your steps to installing CM12

How you reproduced the problem (or a logcat)

Use clear English and don't rage, everyone can help, if you can't help yourself.

Hi guys.. accidentally posted in dev thread and not Q&A :o so here I am now in right place :)

looking to switch from Slimkat 4.4.2 rom on my S2 9100 original Optus Australia phone to this 5.02 CM 12 ROM and read the instructions in first post. However, Slimkat doesn't use CWM and I want to change the pit size to 4GB too but not entirely sure of the order and process of things with these factors

official install instructions

Coming from 4.4- ROMS

Download cm-12-XXXXXXXX-UNOFFICIAL-i9100.zip to your sdcard

Make sure you're using a CWM Kitkat Compatible

Boot into Recovery

Wipe all your data

Flash cm-12-XXXXXXXX-UNOFFICIAL-i9100.zip from sdcard

(Optional)Flash Google Apps.zip from sdcard

Reboot

so for me would be

Use Odin3 3.0.9 to flash a new 4GB pit size and but which kernel should I use ? stock s2 jellybean for my Optus Australia ? seems most downloads are .zip and not .tar does that matter ? edit: okay have to extract zip to get .tar.md5 file

Download cm-12-XXXXXXXX-UNOFFICIAL-i9100.zip to your sdcard

Make sure you're using a CWM Kitkat Compatible - here I still need to flash via Odin3 a CWM like instructed at http://www.theandroidsoul.com/clock...xy-s2-gt-i9100-android-4-4-kitkat-compatible/ ? the CWM Kitkat compatible one is .zip file and not .tar does it matter ?

Boot into CWM Recovery

Wipe all your data - meaning mount and reformat as extfat the sdcard0 + wipe data/factory reset + wipe cache and wipe dalvik cache

Flash cm-12-XXXXXXXX-UNOFFICIAL-i9100.zip from sdcard

(Optional)Flash Google Apps.zip from sdcard (i used nano package from http://xdaforums.com/paranoid-android/general/gapps-official-to-date-pa-google-apps-t2943900)

Reboot

any help is appreciated particularly with steps 1 and 3 of my process and where in the process I should be flashing a new pit file ? :)

did I miss anything ?

cheers

Hey,

I've tried n tested till beta 10 and things worked perfectly for me.

I shifted to other roms and now it has so happened that when i flash cm12[any version] with just any gapps (kk , modular pack, 5.0 pack, cm12 gapps) whatever, it doesnt get flashed properly or i dont know why it's like this that i dont get gapps setup when phone start and there's no google play in app drawer. Google play services isn't there and no gapps work. I tried flashing other kitkat rom, then flashing the cm12. but cm12 works fine but no gapps is working with it . FYI: the gapps used to work earlier for me. But now the gapps problem persists.

I am new to such problem, so tell me what i should try.

Thanks in advance!
