iOS 14.4.2 Rapid Battery Drain

I updated my iOS to version 14.4.2 last evening. Today I charged my device to 87% (from 50) and removed it off the charger. Within a two hour span my battery drained to 51% while using OneNote. Additionally, my phone gave off quite a bit of heat during this time. So much so that I had to put my phone down out of concern and discomfort. I know this can’t be normal. Are there any recommendations for fixing this issue? My mind immediately goes to downgrading the software, however 14.4.2 is a security patch, so I’m reluctant to attempt installing 14.4.1.

Agree. Apple and their software is crap.

That is a joke. It’s Clearly a software issue with Apple and Apple chooses not to fix

To add to the above: I took out AppleCare - it expires October 2021. How do I access this?

I have just reset my fingerprint. It stopped working after the update but is working again now. So just the battery drain to sort out!

Was anyone able to figure this out?

I've since updated to 14.5.1 and am still having the same issues...

Sounds like apple doesn’t want to fix it. Or they can’t.
