Same issue on my iPhone XR. It’s very frustrating!

I’m trying to reply to the comment just below on how hot my iPhone XR is after the 14.0.1 update on 10/2020. I just sat on my bed and my mattress was very warm from my phone!!! What the heck is going on here? Aren’t these software updates tested???? This is the first time I’m considering not upgrading to an iPhone when I’m ready to change my plan. Why release a untested upgrade? And my battery keeps draining. Such a cluster F.
