Iphone 11 heating problem after 15.4.1 upgrade

I have iphone 11 and its been 2 weeks i upgraded to 15.4.1 version. Since then, as soon as I use any application, my phone starts heating up. It also happens while charging the phone. When it starts heating the battery starts to drain very fast. Sometimes I had to reboot it multiple times in a day to cool it down.

any solution?
