I was on iOS 9.0.2 and my battery life was fine. I recently updated to 9.1 and my phone would get super hot, but battery was only a little worse. I reset all settings in hoping that would fix everything but it made it worse. My phone is constantly warm and the battery life is now worse than before. I can barely get a day with use out of it, whereas before I could get a whole day and then some. Any fixes?
