Okay let's get some facts out there, as it seems some of our regular contributors here are not aware of the battery drain issues on iOS/iPadOS 13.4.1 on both iPads AND iPhones.
There is a serious battery drain issue with the latest iOS/iPadOS 13.4.1.
There is also a serious issue with a possible iPad persistent boot loop issue with some iPad models that upgraded to iPadOS 13.4.1.
Some iPads that upgraded to iPadOS 13.4.1 have encountered a never ending boot/re-boot loop that their iPad models cannot recover from.
Apple has no solution and is only offering in-warranty/out-of-warranty iPad replacements for this issue.
MANY IRATE iPad users concerning this constant and perpetual boot loop bug/dilemma.
There is NO fix forthcoming with the boot loop issue or battery drain issues, currently.
Another possible iPad issue is with the Safari Web browser crashing issues with some Websites that started with iPadOS 13.4.
I recommend you just sit tight with your iPad still running with iOS 12, until Apple releases the very final version of iPadOS 13
OR
Just wait it out until Fall 2020 for iPadOS 14 as iPadOS 14 is going to be a complete features fix/bugs fix release of iPadOS.
Best of Luck to You!
