Iphone 5 doesn't show battery level correctly and restarts randomly while charging
Hi!
I've got an iPhone 5 with iOS 7.1.1. It has a problem related with the battery. It doesn't show the battery level correctly, sometimes it's like frozen the % and it doesn't change though you charge it. Onle rebooting the iPhone shows the true level of the battery. When this happens and I've rebooted previously the phone, while is charging the phone is constantly rebooting radomly, maybe every 5 minutes the phone reboots.
I don´t know what to do, all that comes to my mind is going to an Applestore but it's difficult to reproduce the problem.
Regards.
