Updating absolutely destroyed my battery life.
Prior to update, I could leave the brightness on full blast, wifi on all day, location on all day, play youtube during my commute, check all my notifications and such at work, play a game or two during downtime, and make it all the way back home ten hours later with a good 30% left.
I updated on Wednesday night, fiddled with it, decided I liked the new look, and left it charging overnight per usual. Thursday morning I woke up with it powered off and with about 50% battery. Turned off wifi, location, and allowed adaptive brightness, and it still died while I was at work.
Borrowed a charger and basically tricked the phone into charging so I could at least get back home. Left it off, charged it up to ~85%, then turned it back on (still plugged in). Between when I went to sleep at 1:30 and woke up at 10, it was again dead and re-charged up to about 30%.
This is still with basically all peripheral functions turned off! (Actually, I think I turned wifi back on last night, hmm...)
I would love to love Lollipop. I've got the 22.21.11 patch (I think; I can't confirm right now because it's dead again); wasn't that supposed to fix some of these issues? Maybe keeping the wifi off for a bit will let me halfass through until a proper fix?
