First one is common, some system apps misbehave and cause battery drain. Install an app called "usage timelines free" to check which system processes are consuming your battery. Usually DRM-Protected Content Storage (may be deleted or disabled with no side effects, if you don't use anything DRMed on your phone) and Download Manager (can't be disabled or deleted, only solution is to kill it when it appears) are the causes. The first seem to have hight prority, since it consumes CPU usage heavily even when there are other apps needing CPU time, causing, along with low battery life, general choppiness and lag on the system. The latter seem to have low priority, because it only has a high usage when system is idle, so it'll **** your battery life, but won't trouble your performance.View attachment 1696935View attachment 1696936
Having some issues with battery. First 'Android os' is consuming about half of the battery. How can that be corrected. Just point me in the right direction. That's all. Second there are drops and phone just runs in 1%battery for long time.
I did full data wipe and installed this ROM and gapp minimal. I'm not satisfied. It has some glitches other than the battery issues too. It gets very slow sometimes. Runs smoothly otherwise. Some prob with display and ringtones sometimes. But as I sed works perfect otherwise. But I need to rectify the android os consumption importantly. Please someone tell me what's going on . Ne1 else had such an issue.

The second also happened to me for a long time when on CM9 and some time on CM10 (and on some mods, like MIUI, too), than disappeared. It happened again a couple weeks ago, but quickly vanished. I have absolutely no knowledge of its cause or how to solve it, though. It seems to just come and go.
