Massive battery drain after WatchOS 5.2 update

See what it is like after 24 hours. Seems I've read of some people that experienced a quick battery drain within the first part of a day after the update, but things were back to normal after 24 hours. The reset that julieda provided can help with that 24 hour period. Come back if you experience continued issues.

You can do one of the following (probably in this order)

• restart the watch
• uninstall all apps you’ve put on
• Unpair and repair with you phone
• erase Apple Watch settings and content and set up as a new watch (do not restore a backup)
• take it into Apple Genius Bar

I’ve done everything but take it into Apple as I still have issues. All I know for sure is that my issues started when I updated to watchOS 5.2.1

I need some other alternatives, after upgrade to 5.2, after noon(aprox) Iwatch series 2 it appears drains totally its battery , but when I try to charged it again it seems has a good battery life. I try to follow all recos to reset it , but I can not be able unpair it with my iphone. Any recommendation? KR.

I've seen this on a Series 2 watch as well. The weird thing is that I powered down my watch and phone for 5 minutes and then powered back up and all was fine afterwards. Then, a few days later, the power drain restarted again. I updated my watch over two weeks ago.

I've had the same problem for about week. Series 2 watch upgraded to OS 5.2 and suddenly the batter drains completely within 14 hours. I have tried all the tips... Reset, unpaired and re paired. I even turned off all features and set to airplane mode today with the same result. Any help would be appreciated. This is very aggravating.

This happened to me but was worser- after the update the watch died on 2 hours. Strangely the previous day before the update it happened to give me 19 hours backup and still at 20% usage with all the functions used in the watch - calls , workouts and music.

Enter 5.2 and poof it’s gone - came down to 2 hours. I even gave up and said junk the watch - as a last resort went to the apple service center and they restored the watch os. The issue was a corrupted download which somehow got installed and made the watch get stuck in power reserve mode at 75% charge left in it.

Now after the is restore - and 15 hours later with a full workout done for one hour and notifications flashing all day and all the features enabled I’m still at 36%.

However one strange thing is as soon as I wear it in the morning it drains fast for the first few minutes - my observation is that it drained out 10% in the first 25 mins of wearing but settled down later.

Please goto the apple service center and let them restore the watch OS and try again. This issue is not resolvable by resetting or re-pairing the watch - I’ve gone thru that cycle half a dozen times before I went to the service center.

Hope this helps

Dear community Let me share my last attempt : Please asurre any link with your watch is ereased do this in any Apple that you have with the same Apple id, after this perform the reset in both iPhone and Iwatch (please in this case you need to select and push to confirm the reset, yes!! It is a “botton” not only text!!) It seems it works again KR

Exactly the same, watch used to last all day and night and could finish a day starting at 8am and finishing at 4am, still with 30-40%. Now I’m barely getting to 6pm and I’m down to 10% battery. Have tried hard reset on phone and watch, unpairing and rest with no improvement.

Series 3.. was fine until 5.2, i feel very bad for updating. my watch battery used to last at least for 2 days. now its draining out in less than 24 hrs. i thought 5.2.1 will fix it.. but no use. i tried "Aeroplane" mode when not on my wrist, even then the battery drains.. @Apple please do something about it soon.

I am wondering if it is something to do with the bluetooth power. It seems my phone does not seem to last as long now either.

Maybe the low power bluetooth (LTE?) is disabled some how? I am sure my phone used to display low power or lte on the bluetooth connection to the watch

I agree with ChrisJ4203

Give the Watch 24-48 hours, similar with the iPhone after an update there may be some processing the background that will use your battery. The WatchOS may need time to re-index and sort itself.

After 48 hours has passed, if you find your Watch battery life is still significantly lower than the previous Watch OS, you can contact Apple Support and let them know.

- Keep bluetooth turned on, on the paired iPhone as having it turned off increases the battery drain on the Watch

- View Watch usage from the Watch App on iPhone > General > Usage

Already did that several times. Apple support say it's just the way it is. I think their model is you wear is during the day and charge overnight. That model does not work for me. I need more battery life. I had more life (2+days) before the update and now have less than 24 hrs. I use all apple products but this is challenging my loyalty.

I'm having the same issues with my AW Series 2. Unusual battery drain and charging issues; I started checking that my watch was actually at 100% at the start of the day after charging all night and this morning I found it was at 78% whilst still on the charger after 9 hours. This appears to be intermittent and has only started since the update.

I have the exact same issue after the update. Have tried unpairing and repairing from back up, setting up as new watch etc. Nothing seems to make any difference. In addition, messages in the dock move up and down when trying to read.

I believe this may be actually an issue with iOS 12.3 because when streaming music with my iphoneX, the volume oscillates up-and-down. No problems before updates. Telling my family and friends to hold off on the updates until a bug fix is issued.

I updated my series 3 with 5.2.1 and now my battery that use to last two days only last 12 hours now. I also did the reset, unpair and setup as a new watch. Apple looked at my diag and said to mail it in or take it to the Apple store to see if I have to pay to fix it. It seems like Apple can put whatever in there update so that it cost me. I so wish I could go back to the previous update but there is no way to do that, so Apple says. If I get it fixed and working, I will not update if there is no way back.
