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:

Battery Drain since watchos 7.4 - Apple Community

WatchOS 7.5 battery drain - Apple Community

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.)

Unpair and erase your Apple Watch - Apple Support

Also, some people have found that simply waiting a few days after an update resolves the battery draining problem.

With update 9.4 it improved a little bit, but is still nowhere close to 9.2. When I do not drive, I make it through the day now (which is worse than my previous Series 3 watch). When I drive, it drains quickly and I may hit 10 % in the late afternoon.


In the meantime my warranty expired as well. Now I am stuck with this ******** OS update and hope that something better will come along.


I was so happy with my Series 7 up to 9.2. Would love to go back and stay there forever. 9.3 and 9.4 are crap.

But even if a solution works somehowe, which was in my case a complete 'painful' reset of both devices (watch and phone). I'm afraid you'll never get back what the software 9.2 gave us. Then I had a working time of 48 hours on my watch 7 and still didn't really have to worry.

That is beyond remarkable on a device, which is rated at 18 hours. Even Apple Watch Ultra, which as the longest lasting battery in any Apple Watch is rated to 36 hours.

Software has dependencies. Software updates on devices may no longer be comptible with third party software on your phone or watch. Security updates in particular can have conflicts with third party security software (none of which is necessary but gets pushed to gullible users)

Third party app developers bear the responsibility for beta testing including power drain and conflicts, not Apple.

That is why I wrote the ultimate test/remedy is Apple Watch battery drain - the ultimate … - Apple Community in order to completely rule out conflicts and corruptions. This has been linked to in other links.

I am no longer following this thread as the "the update broke my device" mentality becomes boring and depressing after 10 year or so.

I have the 8 and the update that was just about a month or less ago has caused my battery to drain overnight.

Now while sleeping it goes from 80% to around 40% or less from around Midnight to 5 or 6 AM. I cannot figure out what is draining it overnight. During the day it is normal depletion. I might have to go to Apple, which I do not want to do.

There are a lot of suggestions in this 4 page thread. But you only replied to the original poster, so I might guess you haven't read the suggestions. Read the posts and try some of the very good suggestions, which just might help you.

I have an Iwatch series 4. OS system updated to 9.5.2 a few weeks ago and my watch battery started draining fast after the update. Apple support had me unpair and re-pair the watch to the iphone and the issue is still there. They claim it is my watch battery but they checked the battery and it is still within acceptable limits. When I asked tech support if other people were having a battery issue after the update they said no. This is not what I expect from apple tech support when many other people are having the same issue as clearly stated here.

I normally wear the watch 16 hours a day and charge it overnight when I'm sleeping for 8 hours. If I don't take the watch off at night, the battery would last over 24 hours. That was before the recent update.

Now when I use it for exercise (tennis, bike riding, elliptical, etc.), stand notifications, closing rings, the battery dies much faster, like 10 hours. It used to last much longer prior to the update. It seems I was directed to reset and not restore the phone and watch and see if it runs properly, well that is the very inconvenient time issue. I was hoping an update would not interfere so much with older apple products. But I suppose I am griping too much.

I am having a cycling issue. It charges for a few minutes then stops then starts again. I have done a hard reset, unpaired and set up as new and tried 3 different chargers. This only started happening after the iOS 9.3 update on the SE watch. I just finished the new set up and it's on the charger. It was cycling but now it seems to be steady charging. I will update if that situation changes. It seems that Apple is aware of the issue but why haven't they patched it yet? I wish there was a way to roll back updates.

EDIT: Just as I finished typing this it started cycling again; charging/not charging

EDIT2: Now it's continually charging this is so weird.

Watch 9.3.1 didn't solve my battery problems, but it didn't improve them either.

Used to be about 24 hours of battery life with 9.2, after the 9.3 update the battery status suddenly dropped from 100% to 98%.


Fully charged the watch at 07:00 am yesterday, empty battery at 07:30 am this morning.

Now I need to recharge twice a day to get through the night.


Read many solutions here, none of which really helped and only limit the watch in it's possibilities, I guess I'll have to wait patiently for the next major update to fix my/all issues.
