Iphone 5 shuting down all the time after uppdating to ios9
Hello
The last two days I have had problem with the phone chutting down all the time.
100% battery
To start it I just plug it in again and everything starts up as it should. I don't have to enter a pin code.
I have restarted the phone but it doesn't change a thing.
HELP
iPhone 5, iOS 9.0.2
