iOS 14.4 on iPhone X Severe Battery Drain

I upgraded my IPhoneX a few days ago to iOS 14.4. Now the battery drains nearly in front of my eyes. I’ve shut off listen for Siri, Bluetooth and checked the battery for unusual battery consumption and found nothing unusual. When I charge it, I put the phone in airplane mode to speed up the charging. I’ve never seen anything like this. It’s very frustrating to say the least.

I am having the same issue since it was auto installed. I’m using the Apple charger and power block and since last night I can’t even get my charge over 40%. It sounds like it’s charging but then not charging at the same time. It’s drain 5% just while I’m typing this short message 😒

Charge the device when not in use.

What is your battery health?
