Watch Battery Draining Fast

I installed iOS 13 public beta on my iPhone XS Max (watch is still on OS 5) and haven’t really had any issues. However, about 3 hours ago I noticed my Apple Watch battery draining abnormally fast. It would go down 1% every 1 or 2 minutes. It eventually died after an hour. I wasn’t doing anything on the watch, yet it still died. In fact, I used the watch for a 45 minute run earlier in the day and it only drained about 2%. Any ideas?

The watch seems to be working as normal today, so not sure what caused the rapid battery drop.

I am seeing this on a Series 6 Watch, no more beta. Watch was fine until I did the 7.0.2 upgrade. Now it drains very fast, a percent every minute or two, and must be charged 3 times a day, and doesn't make it through the night.
