That's not the case.
I was using my iPhone 15 Pro Max(on 17.0.3) in direct sunlight with ambient around 90F(32 Deg C). Direct sunlight pushed the brightness to max and screen started getting warm. Checked some emails and sent a couple of text messages, brightness started to reduce (screen & side frames got hot). Finally, I took 5-6 snaps using native Camera App (even back got very hot). All this under 5 mins of screen time. At this point, the phone got so hot that the brightness reduced significantly, refresh rate went down heavily and scroll became jittery and lagging (Pro-Motion became Slow-Motion); and Battery drained like an open tap. I could feel the heat ooze out even from Spigen Clear Case.
GUESS WHAT! NO OVERHEATING POP UP WAS THERE.
So, stop hypothesizing that Apple knows everything and they have highly sensitive circuitry to detect heating and they won't cut corners to maximize profits. I repeated several scenarios side by side with my iPhone 14 Pro Max, every time iPhone 15 Pro Max ended up getting significantly hotter.
I have been buying iPhones(Plus/Pro Maxes) for past 7 years now, all on launch day. Something is not right, this time.
Taking it to Genius Bar/Service Centre will be useless as it is unlikely that I will be given an instant replacement. Will wait for 17.1 and stock situation to ease out and approach Apple for replacement.
Really disappointed.
Then guess what? Your iPhone DIDN'T overheat. By your own admission, you used in in conditions which would cause it to get HOT. But it didn't overheat. And your iPhone was doing EXACTLY what it was designed to do, which is reduce the brightness of the screen to avoid overheating to a level it would need to shut down. No "hypothesizing" required. Your phone was operating as it was designed. Note that when you use your iPhone outdoors in bright sun, it goes to its peak brightness of 2400 nits. That causes the battery to heat more than using the phone indoors, where it is cooler.
Sure, take it to the Genius Bar and then report back. They'll likely tell you after running diagnostics, there is nothing wrong with your phone.
Here is a link you can read about why or when your iPhone may get hot --> If your iPhone or iPad gets too hot or too cold - Apple Support
Note the statement about using it in direct sunlight. See, no "hypothesizing" at all.........
