I am suddenly having battery problems with my iPhone 4S.
I am suddenly having battery problems with my iPhone 4S. I purchased it back in December 2011 and have had no complaints. I was also satisfied with the battery life of the iPhone 3G before that.
However, about two weeks ago, I noticed that the phone was noticeably warm and discharging around 1% every two to three minutes. That means I can be fully charged at 8:00 AM and fully dead by noon, without placing more than one or two phone calls and running no apps beyond snapping a photo or two.
I have cleared all running apps multiple times, I have restarted the phone multiple times and it didn't help.
I decided to upgrade the software to the most current release. I was at 5.1.0 (I think) and I upgraded to 5.1.1. Problem solved! It was great, but then the problem recurred about two days later and is continuing.
I am assuming that I have some kind of rogue app that is executing in the background somehow, but I sure can't find it. I am open to ideas!
