The Xiaomi 15 gets pretty hot...
Was filming in 4K 60fps and the phone got insanely hot even without a case on and on a tripod. We are going through a UK heatwave at the moment (about 30 degrees outside), so that might be a contributor, but I thought to upload this as its worth mentioning to anyone interested in the phone. I might upload a full review to the main channel at some point - if I do I'll put it in this description.
