Backup, factory reset, start clean. If still an issue the first thing youll be asked for is a Better Battery Stats log.

The vast majority of people end up solving lots of problems by factory resetting. And ill remind you that you came to us for help, but since you are unwilling to consider my advice I will just have to wish you luck and let you solve it on your own since you already seem to know what all works and what doesn't.
(Quick tip: even if you disagree with what they say, if someone else does decide to try and help you, a little politeness and appreciation for their time will take you much further than you got with me)
