I got this iPhone in Dec. 2012, about 5 months later I was having trouble keeping the battery charged throughout a whole day. Lately it's been draining fast and then dying at about 34%. I've tried every software fix I could find including updating, restoring, and resetting all settings. Nothing has helped. This morning I was answering emails and just doing some normal browsing and I noticed this: 66% after 40 minutes of usage and only an hour of standby? That can't be normal. At that rate my phone would die almost every hour. This was after I plugged it in, too. It was at 63% and 38 minutes of usage before plugging it in. Does anyone know of a software fix that maybe I missed, or should I just bite the bullet and get a new battery?
