iPhone 14 keeps restarting and draining battery rapidly
I have an iphone 14 and it has been all good up until a day ago. It has started to randomly power off, once i have turned it on almost all my battery is gone. it always is at 10% however i am charging it. After it has turned off and on a few times the battery returns to normal. then it is okay for about half an hour and then the process repeats itself. i have looked up it up online but havent found anything. What do I do? i dont want to have to clear my phone. one frequent answer i found was the phone is overheating so i put it in the fridge or could it be some off my apps? how can i check. i have also checked my overall battery life and it is at 87%. my phone is fully up to date aswell. please help me fix this it is so fustrating and i have no idea what to do!
