iPhone turns off by itself
I am using IPhone 6 I don’t what is happening but it is suddenly just going off by itself. When it goes off, I can’t turn it on by power button I have to connect it to the charger that’s when it will turn on but the battery percentage won’t charge. If it went off at 70% even after turning it off the percentage will still be 70% please help me.
