I think this might help.
Before this thread I really didn't notice any excessive battery draw, but since my post above I took notice of when I was actually charging and for how long it lasted etc.
It appeared I had about 25% faster discharge than what I remember having (usually I could go almost 2 full days without having to throttle my usage).
I observed needing to charge about 5 hours sooner.
Yesterday I rec'd my new iPhone so I migrated from the old and the watch did its thing, which I think is a reset?
Today it appears it is back to "normal" about 25-30% drain per 12 hour period. AOD on, cellular, 3 daily walks, audiobooks, etc.
Yeah gonna have to try. Did you do a clean install with your phone - meaning no back up, set up as new. Part of me wonders if the iPhone is having some kind of weird draw.
My watch isn’t on cellular and has Siri turned off and I’m having more draw than you.
