Hi,
I have been using the iOS7 betas from beta 1 to GM, and have noticed quite a lot of battery drain in idle (99%-70%) over a period of about 7 hours with little to no use. I have also noticed that the iPhone shuts off around 7% battery and will then back on after a few seconds of charging. Is there a way to recalibrate my battery?
