[Galaxy S II General] TehAndrewRyan:
Have had massive battery/heat issues lately, can't remember when I started getting these (quite some time ago I think, a couple of months) but I'm currently on CM 10.1.3 Stable and on stock kernel.

Basically my battery would drain as much as 1% per minute without me doing anything more than turning the screen on/off to reveal the launcher (this being done with the screen brightness on minimum). While testing this I've made sure that all recent apps are cleared. This sometimes also works even with airplane mode enabled.

The native battery usage app tells me that the screen is using the most battery, followed by Android OS, something that might indicate that there's a bug in my installation that's causing a battery drain (?). Using the stock battery I was able to get a mere hour of screen on time before the battery pretty much was completly dead. During this discharge cycle I also only listened to music with the screen off very slightly and checked social medias on a few occasions, making sure they closed afterwards. Whenever I didn't need internet, I turned airplane mode on. Both CPU Spy and BBS told me I had few wakelocks (deep sleep being the most used CPU step) although Android OS still showed up as the 2nd most battery consuming part of the phone.

I bought the 2000 mAh replacement battery for my S2 yesterday, but wasn't really able to get a lot more out of it than the stock battery, approximately 1.5-2 hours of screen on time, once again with the screen brightness on minimum and very light use. I felt that this was a massive bummer as I assumed my battery was just getting old and that a new battery would solve my problem, but apparently I was wrong about that.

Apart from the battery draining quickly when just turning the screen on/off, on the few occasions where I played a game or similar demanding task, the top of the phone (camera area) would get REALLY hot, almost to the point where it would hurt to touch it. This is an issue I've had for quite some time now and I've reinstalled CM quite a few times. Even when just browing the web (viewing articles basically just consisting of text) it would get this hot.

What I've done:

* Wiped data/cache (system restore in CWM-Recovery)

* Wiped /system

* Reinstalled CM 10.1.3 + GApps (a couple of times)

* Attempted to clean USB port with a toothbrush in case there would be dirt in there (still can't determine whether I got everything out or not, could a dirty USB port potentially cause a small short circuit or something that could cause the battery drain issue I have?)

* Made sure I don't have wakelocks using battery when the screen is off

* Toggled airplane mode to turn off radios when not needed

I would very much like getting help solving the battery issue, and if possible, the heat issue. I really like CM (can't stand Samsung's stock TouchWiz) but I feel like I should be able to use my phone for at least the majority of the day without having to charge while using the phone very lightly on minimum screen brightness, especially with the 2000 mAh battery that I just bought. If I haven't provided enough information, please tell me what else I should include.
