Does anyone know why the iPad Pro Heats up so easily doing mild work?

So I am a drone operator, who utilizes the iPad Pro as a screen for my drone work. While using it, I do tend to work outside a lot, thus the summer temps are partially the reason to the iPad heating up but sitting in an air-conditioned car is pretty strange. I want to know if heating up is fairly common or just an issue of my device. I am just using the DJI Fly app. I find it reasonable that the M1 could just be that hot of a chip, but the entire iPad overheats and locks-up quite often it feels like. I don't feel the heat is good for the battery either.
