My brand new AWU2 seems ridiculously buggy

Hi, so I just upgraded to the Apple Watch Ultra 2 after having the Apple Watch Series 7 for a few years, I never had any issues with my previous watch.

Firstly, the biggest problem for me is the battery life, I’m losing 1% every 10 minutes or so whilst not even really using the watch, the display is off and it’s just sat on my wrist yet the battery is draining fast anyway, I’ve tried resetting the watch and unpairing it but nothing helped.

Another problem is the brightness toggle, it rarely ever works, when I try to change the brightness nothing happens, it’s just stuck at the lowers brightness, I have auto brightness turned off.

Also, my metrics are all messed up, I have everything set to miles but my watch is hell bent on displaying everything is meters and kilometres during workouts despite me changing everything over the miles.

Another thing is sleep focus, my watch thinks it’s turned on when it isn’t.

So far, the watch seems so buggy for me, I didn’t have any of these problems with my Series 7, and despite owning that watch for almost three years, the battery life was still better then what I am getting right now with the AWU2.

I don’t really know what to do, did I just get really unlucky with this watch or something?
