Experiencing battery drain on Apple Watch after update

So, this week Apple rolled out watchOS 7.3.2. Before I never had any battery drain issues. But since updating from watchOS 7.3.1 watchOS 7.3.2 I experience a battery drain. Is there a solution for this?

After any IOS or OS update I find that a few forced restarts both your iPhone and your watch are needed.


First try force restarting your iPhone by whatever method your version calls for.  As soon as you see the Apple logo force restart your watch by holding in the crown and side button for 10 seconds till you see the Apple logo then release.  Log into your iPhone and wait for your watch to boot, then log into it.


Failing that I'd try unpairing the watch from your iPhone then pairing it back setting it up as new.

Thanks Randy-12, after doing a hard reset of both my iPhone and Apple Watch and unpairing and then re-pairing the watch, the battery drain problem has been fixed (only lost 6% battery capacity in over 2 hours, whereas prior to fix I was losing 40% in battery capacity in matter of hours).


My iPhone is an Apple X and watch is Series 3 with cellular (running on watchOS 7.3.2). When I unpaired and then repaired the watch I re-instated it from backup rather than set up as new watch.
