Battery Draining After WatchOS 9.3 Update

I upgraded my Apple Watch Series 7 Cellular to watchOS 9.3 yesterday and noticed a lot worse battery life. The battery goes from 100% to 0% in just 6 hours and is connected to Wi-Fi rather than Cellular. I have already reset it to factory settings and performed a hard reset, and the issue persists. I hope Apple did not do this on purpose. Is anyone else noticing the same?

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.

Incredibile poco dopo aver effettuato l’update il mio Apple Watch serie 6 ha avuto un crollo improvviso della batteria. Ricaricato un altra volta, utilizzato poco e a mezza mattinata avevo già l’orologio scarico. Incredibile! Ma perché tutte le volte qualcosa va storto? Che sta succedendo alla vecchia e cara Apple super affidabile e super competitiva? Suvvia *** risolviamo in qualche giorno e non tra qualche settimana per favore. Grazie!

My battery only lasts 6 house since I updated my watch. Beyond ridiculous. Especially since it's clear these comments are from weeks ago. So why did Apple prompt me to update my watch last week? They must have known there were issues. Really disgusting. I've tried all the fixes recommended here and none of them work.


Do I have to waste my time going to the Genius Bar? Do I have to buy a new watch?


Seriously Apple, vile, vile behaviour on your part.

My battery used to last from the time I got up 4:30 am until I go to bed at 9 pm. At this point I can’t get my stand rings closed before my battery dies. This is terrible. I know Apple would like me to go spend hundreds on a new watch, but do they not realize the times we are in? The administration that has choked us dry of money? Can’t afford food anymore, how will I afford a watch? I was so happy to get this one a few years ago. Now I might as well throw it in the garbage.

In other words, start at the beginning of the thread and read the other three pages of posts. There are suggestions, some of which might be useful to you.

My watch is updated to the most recent version


it went from having no battery issues to loosing all battery halfway through the day


nothing else has changed


it used to be at 30% remaining when I went to bed


now it’s dead at 1pm (I wake up at 7:30am)


definitely a software issue


apple fix this please

I’m not upgrading if that’s what you’re trying to force through this “bug”


watch is only 2-years old

not cool….
