My fast charge capacity stopped and a week later my battery started not wanting to charge sometimes. If I press hard on the phone or smack it slightly I can get it to charge sometimes. Is this a loose cable or battery all together?
Hi, Pressing hard on the phone sounds like a loose connection somewhere. You may have to open the phone and check. Here’s the ifixit OnePlus 8T Battery Replacement guide, that will help.
