Battery drain after updating to WatchOS 10

Like many of the other folks in this forum -- I have found since updating my WatchOS to 10.0.1, that the battery drain is rapid. I used to get two days out of my Watch and now after eight hours of use I am at 20% with a low battery warning.


What gives? Is there a fix on the horizon?

THANK YOU! I did take your advice and unpaired and repaired my watch to my phone, but I am not sure it really made much of a difference. In one hour I am down 10% of my battery life. It is a bit of a bummer, since before the update my watch was good for the day, probably two days...now it barely survives my work day.


I may try to do this again and see if I get better results.

No, there is no fix on the horizon. These reports surface after every single update, especially major ones like watchOS 10 and almost always resolve themselves in a few days. On MacBooks you get a notification that states “Your Mac is being optimized. Battery Life and Performance may be temporarily affected.” So it with watchOS, iOS, iPadOS.

There is a good chance the “fix” will just need a bit of patience. The software update you watched being loaded is only half the job. After your device is rebooted and you can use it again there are many other tasks running unseen to clean up the old system files and reminded the storage. This is all extra work and extra battery load until it completes.
