iPhone 13 battery charging very slow
So recently I’ve had this problem of my iPhone 13’s battery slowly charging, especially overnight. When I woke up this morning it hadn’t even made it to 100% which made me upset. I’ve tried different cords and blocks but nothing seems to work. I’ve also tried restarting the phone and deleting apps, photos, and changing setting for background app refresh, bluetooth, etc. But nothing seems to be working. Although I have been using FaceTime a lot through this pandemic, could that be the problem or should I look into it more?
