Hey guys, my iPhone's battery seems to be getting worse. When I first got it I'd charge it once per day. Yesterday it was fully charged at 12pm. After making two calls, sending a couple emails and uploading a pic to Facebook it was dead by 7:30 pm. Lately I'm finding I need to keep it docked during the day and then charge overnight to keep it from dying. Is it worth getting a genius to check it out, or is this just typical usage time?
