My 15 Pro Max heats up considerably without even taking a single picture. The other night I opened the camera app, sat it down on my desk and walked away for about 10 minutes and when I came back the entire backside and side rails were really warm. Not burn danger warm but warm enough to be of concern. It may be worth noting that I’m running iOS 17.1 and my device wasn’t in a case at the time. I closed the camera app and it cooled back down. I force quit all background apps, restarted the phone, opened the camera app and again, major heat up within 5 minutes. I wiped the phone and did a clean restore which didn’t help, the phone continues to heat up every time the camera app is open and at one point it got warm enough that my brother said the room smelled like burnt electronics when he walked in.
I don’t know what to think at this point, these phones aren’t cheap and the main reason I chose the Pro Max was for the camera system. I’ve owned a lot of iPhones over the years and never had this problem. It’s weird that it only happens with the camera app, I’m on my phone a lot, sometimes hours at a time consuming media, playing games, etc and the phone feels as cool as it would if it was powered off. The Apple Store is not close and based on past experiences at the “Genius Bar” I would hate to make the trek and jump through the hoops just to be told it’s normal and send me on my way without any resolution.
That happened to me with the 15 PRO. When I opened the camera, even if I didn't take photos, in 2 or 3 minutes it was already hot. It didn't happen to me with the other Apps. In my case I returned it
