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.
Same usage. Half the battery life.
Not sure what to do.
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
