I upgraded my Series 9 to WatchOS 10.2 last night, and just got a low battery warning (at 10%). The watch was on the charger last night, and it's 7hours since it was removed.
Is anybody else seeing dismal battery life? Hopefully this is a fluke, but if it persists, then we have a real problem here.
If the battery drains too fast after an update, see all the replies to:

FWIW, in some cases, unpairing the watch, completely erasing it, then pairing and restoring the backup will resolve the battery draining issue after an update. (Simply unpairing and pairing again may not work.)

Also, some people have found that simply waiting a few days after an update resolves the battery draining problem.

I have apple watch series 8. I have updated to watchOS 10.2 since last week. Now, Batery drain so fast. Pls tell me to resolve it!
To be clear this was for an Apple Watch Series 7, barely 2 years old.
WatchOS 10.2 drains battery in ~6 hours?
