Galaxy watch ultra.

Since last update my battery is poor. I'm losing about 50% and sometimes more within 24hrs. Never drained this quickly before.

I've wiped cache partition, turned watch and phone on and off but made no difference. 

Anyone else having issues or know of a fix

Mine was charged up yesterday evening and over 24 hrs later it's on 82%
I don't use always on display.
But it sounds like you have something running all the time
Maybe a third party watchmaker or something else.

Case of trying different things
Maybe try turning off always on display and just use raise to wake. See if that makes s difference
If not it's a case of trying different settings etc and see

Tha ks for the reply. Yea I've now changed the watch face back to a standard one.
Raise to wake has always been off. Only ever use tap to wake. AOD has always been off. Was all good until the last update.
Checked battery in app and nothing looks out of place.

I'll have a mess about and see if I can find anything else that looks out of place

Bluetooth sync errors can cause battery drain.

I once forgot to turn off Bluetooth and left the watch at home and it drained my phone battery considerably trying to reach the watch.
