watchOS 9 battery drain?

I got a new SE and have been struggling with battery life from day1. Had it 2/3 weeks now and it’s never improved. For example fully charged last night before bed at 9pm, up this morning at 5am it was at 76%, went for a 5k run, come 8am I was at 55%, by 6pm I was low had to put it back on charger.

Ive reset, restarted hasn’t made any difference. The biggest drain seems to be sleep tracking at night, if I don’t track sleep at just start day at 100% it’s fairly okay.
