I’ve been doing a lot of individual experimenting.
The more apps I turn off BAR, the better the situation seems to be, but overall the 15 Pro does seem to be warmer on average than my 14 Pro. I’m going to attribute that to the titanium frame (mostly use my phone caseless) and probably those rumored internal changes.
That being said, I don’t describe it as “overheating”, or even an abnormal problem. It is overall a bit warmer, but still within my expectations.
So far, the only scenarios I’ve found where my phone gets hotter than expected (when compared to my 14 Pro):
- despite better battery life, certain games like Pokémon Go are getting warmer than expected
- Certain websites
- YouTube video playback in the YouTube app
The only scenario where my phone genuinely got too hot to touch was when attempting to record ProRes. It got much hotter much faster than my 14 Pro.
