I owned a Apple Watch S6 and the battery was “all-day” until I upgraded it to 8.5. I get up in the morning at 7am with the battery fully charged and under light use (not opening alot of apps and less than 20min workout), the watch battery got to 10percent at 6pm. I tried many settings like turning background app refresh and Wake Screen on Wrist Raise off and use as little wifi as I can ( I don’t own the cellular version).
I don’t know if everyone else have the same problem
