Latest Apple Watch update draining battery faster

I just upgraded to an iPhone 15 from XS. Watch 7 used to end day at 40-45% at 10 PM. Now it’s depleted by 4 PM. What gives Apple?

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. 🤷

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.

Did you ever find a solution? I just got the 15 Pro Max and updated my watch… having the same battery issues you were!

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.

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.....

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.

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.

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:

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.)

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

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.

Ditto. Same thing.

mine too. it drains so quickly!!! doesn't seem right ...

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

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!
