The watchOS 10 battery life thread [MERGED]

My series 7 has been fine all week on WatchOS 10 but this morning, it has really taken a turn. 3 hours off my charger and I’m currently at 63% battery left. Haven’t changed any routines either. Just rebooted the watch to see if it helps.
 
I updated my Series 5 to release version of WatchOS 10 on Tuesday and didn't really notice any significant battery difference, but today it has taken a beating, down to 16% by 4 pm. Previously would get to 8 pm easily with 30%+ to spare.

Hopefully it is some kind of temporary glitch

My S4's battery will not even get me through the morning after updated to WatchOS 10. My routine hasn't changed. A watch that used to get me through all day with multiple workouts now is at 10% before Noon....make it make sense!

I'm really hoping it's some sort of bug...

I have also sent a feedback.
We have to complain at Apple, not only on this forum if we want them fix this.
Does someone have called apple support for that ?

I have an Apple Watch 4. Battery health status 84%. This update has halved my battery life. I wrote to Twitter support: after the usual diagnostic procedures suggest waiting a couple of days to see if there are any background operations they need to complete. if the battery remains like this, they told me to contact them again

My S4 right now, battery health is 82%:
Took it off the charger at 100%: yesterday, 7:29PM (haven't charged since then).
Today, 6:45 AM: 80%
Now, 7:18 PM: 43%
No sleep tracking.
To me, this seems completely normal.

Hopefully, it'll get better for you all after a few days or after another WatchOS 10 update.
Edit: WatchOS 10.0.1 is out.

Thé bug can be in watchOS… or iOS …
I am afraid these urgent releases are »only « security fixes
but, let’s hope
 
I have just put my Series 8 on its charger (as required) for the latest 10.0.1 update. And the first thing it said was a warning about the "broken ring" indicating optimised (not 100%) charging. First time I've noticed that. But I left it and didn't change the settings.

I'd actually failed to charge it this morning, as I usually do. Watch was still OK at least at 17:00 today from charge yesterday morning.
 
My S4 again today died at lunchtime. Have just done the 10.0.1 update and will report back 👍

EDIT: I am also having issues with complications loading, no idea why but they sometimes take upwards of 10 minutes to show on the watch face after taking it off charge. Surely this is part of the drain issue? In fact after doing this 10.0.1 update the weather and UV index complications won't load at all!

EDIT 2: Battery drain issue hasn't been fixed. Just gone from 50% to 41% in literally 5 minutes

Apple what on earth are you doing

EDIT 3: So the weather complications aren't loading data in and neither is the weather widget anymore! This update has seemingly made this worse! Watch is feeling warm on my wrist and battery now down to 30%

EDIT 4: On live chat to Apple about the issue, they ran diagnostics on my watch and guess what the verdict was? Yep. YOU NEED A NEW BATTERY. I explained multiple times that the issue only occurred after updating but no sense to be had. Incidentally I also asked if they could guide me in how to downgrade to watchOS9 but surprise surprise that isn't possible..

I have a Gen 1 Ultra. Was getting through 36-48 hours easy on one charge prior to updating to watchOS 10. Today was at 100 charge at 6am. 14 percent 9 hours later. Not getting a full 12 hours out of it and nothing has changed other than the update. Massive drop off. That’s a 66-75% reduction in battery life.
 
AW6 updated to WatchOS 10 from 9. Battery now runs out by mid evening, whereas before update about 20% left at 10:30pm so a serious loss of battery life solely due to WatchOS update. I hope a further fix update forthcoming soon or I won’t be able to sell the watch once Ultra2 arrives!
 
Checking in here again. While I did see massive drain the first day with watchOS 10, its back to being normal. I haven't updated to 10.0.1 yet though.

Ended last night at midnight with 51% ish, charged over night, now sitting at 80 after almost 7 hours. Only thing I've done was reboot it after the 10 update once but I'm not convinced that helped since that was still the day it was dropping like 15% every hour.

I have turned off Optimized Charging for the time being.

(Series 8 larger sized one)

Put on my S7 at 6am, took a 35 min walk while playing music on the watch, and haven't done much else with the watch all day, other than check the time or a notification every now and then. 11 hours later, the battery is at 56%. Battery life has definitely taken a hit. Also slept in my S8 for sleep tracking, and when I woke up, the battery was 86%, which prior to OS 10, it was usually at 91 or better.
 
Charged my Series 4 twice today. Got up at 4am and was at 11% at 7am. Got it to 96% before work and got home at 4pm to 8%. This stinks.
 
Add me to the list of people who have a severely degraded battery after Watch OS 10. Using a Series 5 with 84% battery health. I could usually finish the day (between 10pm and 11pm) with 30-40%. After the update, under 15%, and that's without using any apps on the watch. I've had to refrain from doing so because the battery drains so quickly.
 
Series 4 watchOS 10.0, battery draining around 6-7% per hour.
Had battery indicator error too yesterday, suddenly my battery "dropped" from ~80% to 10% but stays there for 9 hours before it started dropping again to 9% (around 6-7% battery consumption per hour)

This is so badddddd....
 
Installed 10.0.1 this afternoon and battery is noticeably much better, about 4% per hour. Prior it was 6% or more. This is more inline with what I experienced on OS9. Hopefully it will improve a bit more after it settles in.
 
My Series 7 still is getting horrible battery life and I updated the first day WatchOS10 was available. So not happy. I have to charge it twice a day with my usage.
 
My series 5 has been off the charge for 5 hours now and it’s just over 50%. Usually it takes about 12 hours to get to that level. Also for the first time yesterday my watch turned itself off due to low battery.

I guess this is part of Apple‘s upgrade strategy.
 
Doesn’t this happen with pretty much every x.0 release? I just don’t think those versions are worth risking. And I think Apple should find a way to incentivize beta testers for reporting bugs. No point in letting people upload the beta if they’re not going to bother reporting bugs. I could of course be wrong but I bet that the majority don’t bother reporting any bugs and don’t bother using the OS outside of the most basic use cases. Apple provides incentives for security flaws; I think they should for beta bugs too. Obviously at nowhere near the same rate.

A lot of beta users have complain about battery life. Each time a beta user complains, we say him he hasn't to complain because it's the risk of using a beta version ...
Apple has not put the battery complaints on top of their priorities, it's their choice.

You’re right, 100%. I wasn’t clear, but I meant that the totality of the bugs, including and beyond battery life, seems to have enlarged on x.0 releases. It’s not just battery life, that IS to be expected on beta releases, but it’s the other bugs too. I think it’s a larger procedural change that needs to occur with regards to how Apple does pre-release testing and incorporates beta feedback.
 
I updated to 10.0.1 last night. Fully recharged at 22.30pm

This morning at 7.30am after a run for 40min. "no app" I am on 52% now. Normally is will be around 60-65%

I don't think this update from last night has any affects on the battery drain.
