Similar for my partner & I.
Happening on 2 iPhone SE3’s. 
Straight after the update today. Battery drains really fast & phone overheats so fast that it’s too hot to hold. 
My partners phone battery actually swelled up & we had to turn her phone off as we were scared it was going catch fire. 
This update has damaged her phone battery & Im going to need to get her battery replaced. To say we are unhappy would be an understatement.

Going to cost over $150 Australian. 😡
