iOS devices overheating after 1.16.20 update

I played Minecraft that morning on an older version and my phone was just fine but as soon as i update it, my phone would get incredibly hot to the point where it's unplayable. i play on an iPhone XR ( which is only a year old). I also play with bluetooth headphones and controller. The gameplay is fine, i don't lose fps, but my phone itself just heats up to unsettling temperatures.
