I had just replaced my iphone battery and screen at the mall today and after i went home it worked perfectly it was a little hot . Then i left it alone for 5 min and come back to it and it wouldn’t turn on . i let it charge for a while but it still wouldn’t turn on . what could it be and how can i fix it ?
If you had your screen and battery replaced at a shop, then go back to the shop so that they can take a look at it. Chances are it is a bad replacement part and they should replace it free of charge. If they did any other damage, they should take responsibility for that as well.
