EDIT: 2% lasted 27 hours, most of the time in standby. If only every 2% lasted that long then the iPhone 5s would have 56 days of standby! --- Does anyone else's battery percentage drop a bit too quickly and then get stuck at 1-2% for hours? (right now my phones been at 1 & 2 % for 18 hours) I've done 3 full drain/charge cycles to calibrate the min/max voltage and drain curve, but so far it hasn't helped at all. I really don't want a refurb, so please guys tell me this is a problem with iOS 7 .
