It's literally the app complaining about it: https://a.dropoverapp.com/cloud/download/b191e7b8-8dad-4fed-...
It will dim the screen soon, so much that it's unusable outdoors. I wasn't able to capture a photo outdoors yesterday using this app because of this. The first photo slowly finished processing but the app crashed, lost the photo. Then the device was overheating, the screen dimmed to unusable and the FPS dropped, the app become unresponsive and the music went away, the AirPods re-connected. Couldn't even try to capture a second one.
It wasn't even that hot, just 28C.
I’d be shocked if this is an actual limitation of the hardware. Modern iPhones have plenty of horsepower for computational photography.
I bet this a software bug of some sort - like they’re using the cpu where it should be using Metal or something. Hopefully they can sort it out.
iPhone have less ram though, compared to Pixels and androids in general.
I have the same phone and no overheating errors here.
Do you mean the phone got slightly warm? That’s not overheating, it’s just what happens when you use an app that leverage the CPU for anything non-trivial. It’s not overheating.
EDIT: The screenshot below clarifies that the heat warning is a message in the app, not the actual iOS overheating protection as ( https://support.apple.com/en-us/118431 ). Regardless, I still can’t trigger the in-app temperature warning on my phone.
