Same-my usage on my AW4 GPS has been consistent (with the exception of enabling sleep tracking on WatchOS 7). Prior to upgrading, I would fully charge each morning and have 40-50% charge the following morning when I would recharge with my light usage. Overnight, after upgrading to WatchOS7, my battery goes from fully charged in the morning to ~25% at bedtime, which my watch reports is inadequate for sleep tracking. I’m now having to charge TWICE per day. Frustrating.
