Omg, now I know I’m not crazy. I’ve been having the same issues with my IPhone 13 Pro. I do a lot of driving (with use of phone) for my job, therefore, I am exposed to the elements quite a bit. It could be warm or cold outside and my phone still manages to overheat. Doesn’t matter whether it’s plugged into the car charger, home charger, or no charger at all. It’s quite irritating, because it got so hot, that one time my phone was sitting on my bare skin in the car… and had I left it on longer, I’m sure I would’ve gotten burned. Unfortunately, my phone is out of the 1 year warranty… just shy of a few days and after months of procrastinating to get it fixed, it is imperative to do so at this point. This phone is a big investment and is used every day, but I shouldn’t have to fear it blowing up on me at any given moment or malfunctioning when I need it most. When it over heats, it glitches and freezes too! So, I guess it’s already malfunctioned quite a few times. I only use Apple USB-C charging chords. The original chord that came with the phone and a chord I purchased from the Apple store. So I’m not sure why it’s overheating like this. It’s effecting my sense of safety and money at this point. No Bueno.
