[Q] Bad battery life

[Vitor_Hugo]

Hello, 3 days ago I've installed CM10.1 nightly build from 2013-07-25 on my friend's Galaxy S III (international), now his battery life is really bad and he's complaining on me, any way I can improve the battery life?

Here goes a screenshot (as you can see, he wasn't even using the phone when the battery just dropped 50%):

Cyanogen mod roms are known to drain battery much faster than touchwiz.so you cant really expect the battery life to be the same as on stock or stock based roms. you may improve the battery life by using an app called Greenify. it hibernates apps so that they will not run in the backround. this can help considerably. also make sure to turn off gps , bluetooth, wifi. and mobile data when not in use.

well first tell your "friend" that thats how things are in AOSPs. Secondly use differrent kernels and proper setting to get max battery (tutorials are available) plus greenify apps you do not use. And the usual killers as GPS/WiFi/NFC/3G use only when needed or turn them off..

Something is extremely wrong there. Get a normal usage BBS dump and post it here. Also take screenshots of the BBS pages.
Also post a screenshot of your battery stats page (one that shows which apps drain battery).
