iPhone 8 keeps shutting down
My iPhone 8 keeps shutting down on a full battery unless it’s plugged into the charger. When it’s unplugged it’ll last all of 10 minutes before turning off.
it won’t turn back on either unless I plug it in. And at some points it will say that it’s got a low battery when I turn it back on even though it was fully charged 5 minutes ago. I’ve been told by a phone repair shop that it needs a new battery but I’m unsure if that’s the case?
