I've noticed my iPhone get hot the most while using the camera. Especially while taking video, but after a few photos it gets hot as well. I was on vacations last week in a tropical country and took a lot of photos with my 16 Pro and it gets so hot after just a few photos that it starts lagging A LOT due to the throttling.
I'm sure this is handy for LLM usage, but this was a problem before those were a thing I'd say.
I have the same case, iPhone 16 pro is getting really hot when taking photos and videos it’s unbearable. I will change my phone for that reason, the battery melts right away …
I noticed something though, when taking a picture with the x5 camera if I cover the main lens the brightness changes. So I think the iPhone now merges the two stream to enhance quality. That wasn’t the case before and that might be why the phone is getting hot
