When I was on 2.1 I would have a full day of heavy usage our of the phone and still come home with 70-80% battery. Today I used it the same way and came home with 40%, then after the gym it was at 5%! FIVE...I've never seen the battery that low. I've used Advanced Task Killer multiple times today, still was low. It's now been charging for nearly 3 hours and only at 40%. Anyone know why the battery is so much worse?
