I have been using my Galaxy Watch 4 Classic since last year so I'm familiar with it and my usage patterns to know what to expect. I usually get 2 full days on a charge.
Switched to the S22 Ultra recently and got a really good deal on the Samsung Wireless Duo Charger. Started using that for both the phone and watch at night. I've noticed a dramatic drop in battery life since then. It was fully charged this morning and now I only have 26% left.
AOD is not on and I don't use the Watch much aside from checking notifications. Not using GPS either.
That's easy you tend to forget your phone is on a wireless charger more often they needed that charges twice as fast then a charger with the USB cord and when you leave anything on a battery fully charging more times needed eventually it will drain the battery itself
