Since the recent up date my Apple Watch Series 7 lte had a weird battery drain issue normally after 3 1/2hrs my watch would drain about 20% which is normal because I keep the always display etc on but every since the recent update it would drop 20% on random days after 2hrs and then another random day it rapidly drained 60% in 1hr my battery health is at 85% so this shouldn’t be happening

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.
