If OP uses the iPad plugged in all the time (which definitely isn’t recommended, but nevermind), then the main issue with all of these updates on the 1st and 2nd-gen iPad Pros is not all too noticeable, but battery life on the 10.5-inch iPad Pro has been utterly abhorrent since, at least, iPadOS 16. Earlier it was poor of course, at least since iPadOS 13, but iPadOS 16 pushed too far. iPadOS 17 probably pushes that further, but like I said, not totally relevant for the OP, even if using it plugged in all the time will destroy the battery sooner rather than later.
As far as the iPhone 11 goes, if screen-on time is 0 minutes, 100 to 17% in 8 days of pure standby is mediocre to say the least.
