I've had this issue too. My iPad pro is generally within 4 foot of an airtag which is attached to my keys. During the day I don't see any real battery drain however during the night it seems to be draining the battery at an accelerated rate.

I'd wake up and check it within the battery info section to see Find My using 90%+ of the battery over the last 24hrs.

I now have a shortcut setup to disable bluetooth on the iPad from midnight > 7am. Find my usage drops all the way down to <2% and battery drain is very minimal - if I leave bluetooth on overnight it jumps all the way back up and drains approx 40-60% of the battery overnight.
