My series 5 seems to be running out of power very quickly. Anyone have similar issues or know how to fix?

If the battery drains too fast after an update, see all the replies to:

Battery Drain since watchos 7.4 - Apple Community

WatchOS 7.5 battery drain - Apple Community

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.

Im having the same issue and its making me quite upset I pay $500 for this, it was completely fine until I updated my watch the 10.1 this is absolutely ridiculous what can I do to fix

did you find a solution to this? I just bought mine today and it’s having the same issue.

Have you found anything I have a series 5 and it was at 70% when I woke up (5am) and now it’s at 24% 12pm on my lunch break. It came in literally yesterday.
