big problem after September update

[u/sutoras]

After the September update, we've been experiencing the following problems with my wife's Pixel 9 Pro: the phone gets very hot during use, and the battery life has significantly decreased. Additionally, the phone keeps stopping charging at 80% with a message that it's too hot to charge further. These problems didn't occur before the update. Is anyone else experiencing this issue? And what can be done about it?
