iPhone 11 is hot and battery is dying fast (exited all Apps)

[ghsDUDE]

I noticed my phone is getting hot on the back right side (middle back right side) and the battery is dying fast.

It started happening right before iOS 14 and it seems worse with iOS 14.

It’s a new iPhone 11 and I did notice that Health and No Cell Coverage seem to be the two contributing factors.

I’m connected to WiFi in my house...any idea why this is happening?

How's the cell coverage?

The cellular radio is constantly searching for a signal. Huge contributor to rapid battery drain.

The same thing happened on my iPhone se 2020.

Running very hot and very fast battery drain.

Is there anything we can do?

I’ve never had good cell coverage in my house, but I use TMobile WiFi and that always worked.

Something in iOS14 is causing it to run all the time.

Did you try turning it off and then on again? This seems to happen to me every once in a while and a restart usually fixes it. It's like some rouge process starts running and the only way to kill it is a restart.

Edit: I guess it would've restarted during the iOS 14 upgrade process, but have you restarted it again since?

I did and no luck. I reverted back to 13.7 and did a fresh system restore.
