I guess I could try the temp restore and see if that helps.
Here is a screenshot of my phone yesterday. After about an hour and a half it's already down to 65%. The phone is almost always warm to the touch. There's also a screenshot from BatteryDetective. Shows a lot of drain and battery temp. That's with nothing running in the background.

edit - I know that the true battery capacity was higher before all this started and it is going down alarmingly. I think that whatever is draining the battery is wearing it out faster as well. FML.
