Same here. Apple Watch 3. Before update I got from fully charged 1,5 day with sleep tracking 2 nights and 1 PT session. Now I am down to under 50% from just one night (8 h sleep). Absolute disaster!!!

How are you guys doing after 7.3.2 update?

Latest iOS update (14.4.1) seem to have sorted out the problem for me.

Worked fine a few days. Now back to same problem again. Hoping 14.4.2 will work it out.
