I have updated the iPadOS to 15.2, but my iPad Pro (9.7”, 2016) battery drain is the same as previous version.
I’m very disappointed!
Have anyone the same problem?
Are you able to share your battery history graph with apps reporting usage? I believe others have stated such issues but I have not seen any other reports yet on the final bits.
From many previous updates - you really need to wait a day or two to determine battery life. You may certainly be having a problem but systems seem to do a lot of "indexing" after an update
