Still having issues..... My iphone 5, which is running the latest update, will only charge to 86%. If I unplug the cable and then plug it back in, it will go to 87%. I thought that this could just be a display issue, but the battery is not lasting as long as it should (or even close). Things I have tried - Reset the phone using itunes. Let the battery drain and calibrate it. Charging for a long time, etc... I had the battery replaced and the issue did not change at all I have tried multiple cables, etc... but all charge my wife's phone fully. Any ideas? I was sure replacing the battery would solve the problem, but it didn't change anything. I am lost.
