iPhone 12 heating up while charging
Hello, i’ve bought the iPhone 12 last week and tried several different options for charging since then. First I charged it with my old iPhone 8 charger, but it was charging the phone for too long, then I tried it with the usb-c charger that comes with the iPhone 12 through my computer, but my laptop battery dropped quickly while charging, so I decided to buy an adapter for the charger, but when I charge it like that, the phone gets very warm during the first 3 minutes. Is it normal or not? If not, could the adapter be wrong or “too strong”? Thanks a lot for advice.
iPhone 12, iOS 14
