IPhone X here. I experienced the same issue. Was considering to downgrade but somewhere I read this battery drainage was due to some background indexing of the contents of the phone and that it should last for 2 or 3 days. I decided to wait and now, 3 days after the upgrade my battery fife is back to normal. Hope this helps!
