iPhone 14 gets to hot while charging?

Howdy! Charging produces heat, this is normal. Some phones get hotter than others as a result of multiple factors, some of which could be thermals, the build of the phone, how fast it's charging, battery health, what you're doing on the phone while it's charging, etc.

I have seen multiple people complain of the 14 models getting hotter than others while charging, so I think it's normal. I would not worry unless it's extremely hot, in which case I would take it to be checked out by a professional. Hope this helps!
