Does anyone else have this issue of the indicator jumping percentage by a significant amount when charging or discharging? Happens to me both ways like yesterday when I had it drop from 23% to under 10 percent in a few minutes of playing Infinity Blade 3. (I was trying to run it down to see if the problem is a calibration issue). Happens since upgrading to iOS 9.0.1. I was in the Apple store to test the battery and the genius said my battery us normal (iPhone 6 bought last November). I wonder if it has something to do with this low power toggle (had it off)? Any ideas?
