Latest Apple Watch update draining battery faster

I noticed that I was suddenly losing power by mid morning after an update. When I went to investigate, I found nearly all possible notifications had been turned on in the watch. I turned them back off except the two or three I usually use. The battery power is now lasting like normal.

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.

Check your Bluetooth.

I had the new 15plus and the new iwatch 9. I had turned off Bluetooth for a different reason and it wasn’t until three days of nearly drained iwatch that I reconnected. Problem solved. At least with the iwatch 9, I suspect it was hunting GPS for location or cell towers for signal.

Check how many notification got turned on in your phone and watch if you have one. Updates seem to reset them and they suck power.

Settings > General > Reset > Erase all content and settings.

After that, just pair my watch to my iPhone.

That fixed it for me

reformatted like how? I turned off my mobile and watch, after speaking to Apple Support. Overnight battery drained quickly still. I put it on charge this morning and used it. Appears to be good so far. He did say, takes 24 hours... seems to be right and working ok now.....

Same with me. Watch 7 series and a 15 pro max. Seems worse with the 10.1.1 update. 50% drain in 3 hours. Just unpaired and restored from backup. Hope that works.

I reformatted my apple watch asked its working fine now with the latest os update.

I’m having the same issue. I have the 44mm Apple Watch Series 6 (that I’ve had since the 6 came out). I Just got my preordered iPhone 15 Pro Max and paired my watch two nights ago. There also was an update for the watch- so I completed that. My watch will go from 100% to dead in about two hours. Always On display is off- and I’ve gone through since then and turned off so many things to try and stop the battery drain issues. I really hope this is an update issue and not an issue with the 15 Pro Max and watch together. I just switched from the 13 Pro max (and previously had the XS Max when I got the watch), and have never had an issue with the battery draining after any update or phone it’s been paired with. This is super frustrating.

I did the latest update and surprised it worked. Night and day on battery life. Might try checking overall battery heath. If it is below 80% then might involve battery replacement. Did you also do latest update on phone? It’s frustrating I know and trust me, if the update did not solve issue I’d be on line with Apple support today as it is under warranty. Good luck!

I got a 15 pro max a month ago and revived an old series 4 (2018) iWatch from family. It worked great! It would last up until bedtime, then I'd put it on a charger (so I'd get say 16 hours out of it). It was a few iOS/watchOS versions behind so it installed one, and it seemed ok, then THIS LAST ONE KILLED IT. I lose about 1% a minute. I have (sorry, to your point) Erased it several times. Unpaired and re-paired. Erased again. Repaired again. Then I just didn't even pair it. I just left it on. It still drained fast. I don't have any apps on it. I didn't change the default face. The OS update has killed the battery life. I'm livid. Its a perfectly good watch, and was just a few weeks ago! ugh.

Has anybody found a solution for this, other than erasing content/repairing? Those don't work for me, I have tried 10x, but any watch I am pairing to my iphone drains drastically. I had faith in 17.5.1 update from yesterday, as they wrote they have fixed several important bugs, but I see no change.

Those who STILL face this issue on 21.05.2024 or afterwards, can you please check your phone's and watch's storage? Isn't the "other"/system data section very big?

I tried erasing my SE watch and repairing it with my phone. Still didn’t fix it. My watch will drain out from a 100% in about a couple of hours. Interesting fact though that I didn’t have this problem until I paired it with my IPhone 15 Pro Max. 🤷

All the above applies to me as well, did the update at the same time I bought my new iPhone 15 Pro. I talked to Apple and they told me that it was a bug fix coming. They need to hurry up.

I started having this problem on 5/21 after upgrading to a new iPhone 15 Pro. My watch died by 11am that day. My screen doesn’t even come on unless I force it to. The following day it suddenly wasn’t syncing with my phone. Today I erased my watch and restored it. Didn’t work. I’ve had to charge my watch 5 times today.

Ive been an iPhone user since 2009 and had Apple Watches since 2018 and I’m at the point where I never want to purchase another overpriced apple product again.
