I received my Apple Watch Series 10 on September 20 2024. Worked perfectly for one week then on September 29, it suddenly went from 80% at noon to 20% at 5 pm. I am tracking the time now but I can see that it is significantly losing power every hour. I rebooted, but it is still losing significant power. Unless I can come up with a solution, this watch is going back!

Apple Watch Series 10, watchOS 11
I took mine off charge at 5am today and by 12:30pm the battery was dead. Haven’t done any workouts. Infact I’ve hardly used it at all in that time. Up to now my series 7 that was at 81% battery health was lasting longer between charges than my series 10 watch is. The battery life was the main reason for me getting a new one too.

Haven’t changed anything after the last update, which was watch os 11 on the 20th of September and first of all I was positively surprised that watch lasts around 30-36hrs. Two days ago it went from 100 to nil in 18 hours and today died after 14 ish. Definitely something going on in the background, like I said i didn’t change anything and the way I use the watch.
Watch face! If you using one of the new ones, that’s the problem. I did change it to one of the old ones and boom, watch is back to it’s normal.
Did you try to unpair it, set it up as a new device and disable the Live Activities as well?
DO NOT run the Apple Watch battery to zero just to see how long it will last. That is the fastest way to destroy a Li-Ion battery.
You should either charge it overnight while you sleep, or if you are doing sleep monitoring, put it on the charger while you are getting ready for bed, and put it back on the charger when you get up in the morning and are getting ready for your day.
Even if you have an Ultra, you should not push the battery to its limits. The Ultra has a longer battery life so you can be away from power sources for a longer period of time (or participating in a marathon, or ultra-marathon), but you should still charge it daily when you are home.
When I got my Series 10, I power cycled it 24 hours after getting it, then I power cycled it 48 hours after getting it. It has been holding its charge very well after 10 days. I do sleep monitoring, so I do the getting ready for read, getting ready for my day charging I mentioned above.
You're welcome, glad your battery life improved 🙂
Maybe also let Apple know about the issue by using the Feedback link:
Is your work iPhone a managed device? Which iPhone do you use?
Did you report your findings directly to Apple by using the Feedback link?
This is the only way to make them aware of watchOS issues.
Good Luck!
Unpairing worked for me and brought back the battery life again on my Ultra 2
Yeah, I changed my watch face a couple of days ago and it seems to have sorted my issue. Battery’s gone from lasting 7 hours to doing 16 hours and still having 30% left at the end of the day.
Not seeing that watchOS 1.0.1 has improved situation. On my Series 7it is worse.
Just sitting at my desk, it has gone from 100% to 28% in 6 hr!
yes, I was thinking of that too in case it recurs or there’s a problem with the watch. I’m sure they know about it already but I’ll inform them today. So far it seems to be holding the charge after I did what you sugfested. Thanks for the link and your assistance. Much appreciated!
On my appleWatch 8, the battery just started draining only just last week. My battery went from 100 to <5% in 6-7 hours. I tried the update, but it didn't help at all. I am now trying the unpairing and re-pairing. I hope it works. until this started, the battery previously would last for over 30 hours, and now it is dead only 6-7 hours into my day.
I also got mine on day one. It worked fine for weeks - then out of the blue it just drains. Charging time has gone from 30 mins or so to many many hours. I sent mine back and received a replacement. It does exactly the same thing. I setup as new, and restored from backup - it just keeps draining and then takes forever to charge.
I have tracked down the problem and it's not acceptable. It is my Iphone that is causing the problem. Both watch and phone on latest software release.
If I power off my phone (it's my work phone so this is not an option) then the battery suddenly stops draining.
I have removed most apps from my watch but it still does not help.
Watch has gone from 100% to 80% in less than 45 minutes. I have turned off my phone and the watch is still at 80%. So, there is definitely something going on between the phone and the watch.

Tried one more thing - turned off bluetooth on watch - powered on the phone - 79% after 30 seconds, then no more battery drain for 5 minutes. Turned back on Bluetooth on the watch, before 1 minute, 78%, 2 minutes in, 77%, 3 minutes in, 76% - Turned bluetooth off on the watch - dropped 2% rapidly then within 4 mins, down to 71% so I can only attribute this to communication somehow between the phone and the watch because when I turn off the phone, the watch stops losing power.
Why is my Apple Watch 10 battery suddenly draining so fast?
