I also have battery drain problem. It went bad after upgrading to 6.0.0 now is even worse with 6.0.1. My battery lasts just one day and a half. I easily used my phone for 4-5-6 days with Stamina before so now is disaster. I did factory reset just to make sure something didn't upgraded wrong but same s**t... Solutions in the pointed thread didn't help.
