Iphone 5 keeps turning itself off
Hi
Ive had iphone 5 since it came out, and recently this year, its been turning itself off with plenty of battery life and wont allow me to turn it back on until I have plugged it into wall charger to 'charge' it back up. When its plugged in, it returns to the battery level it was originaly at....30%, 50% for example.
Has anyone else experienced this issue? Im going to do a iCloud and computer back up and restore firmware see if that helps?
