My Battery drain is not as bad as OP but my brand new series 10 watch is definitely battery draining noticeably faster than before I updated from 18.5.

It doesn’t work for me either. I have tried everything but nothing ever comes out my earbuds. It’s kind of annoying because I have to keep testing by it by starting workouts after I change a setting. I’m on a 16 max, series 10 with beats earbuds. Workout buddy never works.
