Watch Series 4 - Since upgrading to WatchOS 10, my battery life went from ~16 hours down to 3...

As the title says, I have an Apple Watch Series 4 (40 mm) no LTE, and up until last week when I upgraded to WatchOS 10, I was getting upwards of 15-16 hours per charge on the watch. I upgraded to WatchOS 10 last week and ever since my watch has been going from 100% to 0% in 3 hours without any heavy activity. I have turned off handwashing, sound notifications, background updates & meditation reminders but the issue persists…. My watch is basically useless with the current time it stays alive.

Is there any way to downgrade back to OS9? Am I the only one with this issue on series 4?? I have seen others report issues with degraded battery life on newer models, but nowhere close to the 3 hours I am getting.

I have reset, rebooted, repaired and nothing is working.

Apple Watch Series 4, watchOS 10

Don't worry. All Apple Watches usually take a few hours to a few days to index through the new files and settings post-update. As an apple watch owner myself, giving it a few days and then shutting it down and rebooting it restored original battery behavior. And as far as my knowledge goes, it is not possible to downgrade to WatchOS 9.

Btw, is the update the Beta update or the official public release? If it is beta, update to the official release and follow the steps above.

Have a great day!

So I think I may have fixed the issue…

it looks like podcasts was causing the battery drain. I changed the podcast setting for ‘up next’ from 10 to off and now my battery seems to be almost back to normal

I did some researching, and I found that Wiping your watch completely (don't worry, data is saved on iPhone automatically), and then repairing it brings it back to normal behavior. Please try this and let me know if it works.

Have a great day!

Hello, it’s the official release. Also, it’s been like this for 5-6 days now — is there any way to check on the indexing or status?

Not that I know of, but try placing the watch into Battery Saver Mode and then Reboot it. Oddly enough, it worked with my Father's Watch, so I do hope it works with yours.

Have a great day!
