IOS 15.3.1 drain my iPhone 8 battery

Updated my iPhone 8 to IOS 15.3.1 yesterday and this morning found out the iphone battery was drained and shutdown. When I put it on charger and turned it on, the iphone show 10% of battery.

Then I charged the iphone battery to 100% and use it for couple of minutes, the iphone shut down again as if it is running out of battery. When I turned it back on again it show my battery from 100% to 10% and it's repeating the same thing every time. This mean I can't even use my iphone as it keep shutting down due to drained battery.

Is there any solution or I've to wait until the next ios update.

Presumably the changes in iOS 15 are to avoid possible negative experiences for the user:

You’re gonna have to get your battery serviced at a Genius Bar.

I have 2 iPhone 8’s both 256gb unlocked. One is running on 14.7.1 and works FLAWLESSLY with any replacement battery. The 2nd iPhone 8 running on 15.3.1 will not even show a battery percentage on ANYTHING other than an OEM battery stripped from an original iPhone 8. Currently trying to restore a backup of 14.7.1
