iPhone 7 powering off randomly.
I have the jet black iPhone 7 running IOS 11.1.1 atm and recently when it gets to around 10-20% battery it randomly turns off and shows it needs to be plugged in.
Then i power it up and its on for a second you try to open an app then turns off again.
Seems like its a software problem since its only happened with IOS11. But im not 100% sure.
Any suggestions?
