Rendering dragon causes serious problems

I found that in the mobile version with the Render Dragon, my device started to get unusually hot and stuck. This problem becomes particularly apparent in 1.20.
In 1.20.81, I only played minecraft bedrock edition for 2 hours
The result was a pop-up message on my phone that minecraft caused the device to overheat and drain power too quickly.
I hope mojang fixes this issue soon, because I can't play minecraft properly on my Android phone at this point
