I think I've found my issue. I switched back to Holo yesterday, so I had to rebuild my screens, etc... That took battery, so I thought I'd give it a fair shot today. It's been unplugged for about 2 hours, and I'm already at 88%.
I noticed that my screens was on super dim though from a text I got a half hour ago!
I'll be monitoring that all day now... Anyone else seeing this issue?
