Hi guys, I've been running iOS 7 with only a few bugs so far. I received a MOTA iPhone 5 battery case today and it charged up fine, but when I try to charge the phone from the external battery it shows it's charging for about 20 seconds then stops. Does anyone else have this problem? Do you think it's a battery case issue or an iOS 7 bug? Are any other external cases having this issue? Thanks!
