Apple Watch 8 not Tracking Sleep & Sleep Stages

Hello all,


I have an Apple Watch 8, running 9.5 (at the time of writing). This is paired with an iPhone 14 Pro running 16.5


When I first got the watch, an upgrade from Series 5, the sleep data appeared perfectly, showing stages and tracking correctly. This was working in tandem with AutoSleep which I was previously using. No issues for the first couple of weeks, then suddenly, the Apple Sleep was just showing the block of time my phone & watch were in 'Sleep' Focus, with no information on the stages. Some nights NO DATA is recorded at all. The sleep graph in Health.app is absolutely empty. Other nights I see only the green bar showing time asleep and time awake, but no stages. And that data is absolutely wrong. For example, tracking starts 3h after I have gone to bed. I regurarly sleep 7-8h and the Sleep in Health reports 1-2h of sleep.


Every once in a while everything is tracked perfectly....like every 9-10 days. Last night's sleep was tracked correctly. The night before the graph was absolutely empty. Today the graph is a mess with wrong data, a green bar only, and no stages.


I have tried:


  • Verified all tracking metrics are on and allowed under privacy;
  • Ensured wrist detection is turned on;
  • Kept watch charged (always 100% at bedtime);
  • Made sure Sleep Monitoring is turned on on Apple Watch;
  • Deleted current sleep schedule, turned phone & watch off and on again, then set up a new schedule;
  • Deleting Autosleep from both phone & watch;
  • Turned off 'Track time in bed' on iPhone;
  • Made sure Apple Watch 8 is first in the 'Data Sources' for sleep;
  • Reset the watch entirely to factory defaults, then paired it up again;
  • Turned OFF "Share Across Devices" in Focus (off on ALL devices).


Sometimes it will randomly track again for a couple of nights & then go back to tracking nothing or tracking wrongly.


This is super frustrating as it links into my fitness apps, which all think I am now not getting enough sleep so they adjust metrics accordingly (wrongly).


Any other solutions people have found other than those already tried above?


I'm in touch with Apple Support over the phone for 2 weeks now. Support is super kind and helpful, but they also can't figure it out. The issue has been escalated. Support has done Screen Sharing, checking settings, and adjusting things. I test Sleep for a few nights and then I call back (the same person via a special link) for further troubleshooting. So far, no good.


Any feedback and suggestions are very welcome.


Thank you!

Greetings Kostadin,


It sounds like Sleep tracking on your Apple Watch isn’t working correctly. We know how important having a working Apple Watch is for you, and you’re in the right place for answers. Please make sure you verify your settings and schedule:


Verify Settings

  • "Sleep Schedule" needs to be turned On, in:
    • iPhone > Health app > Sleep > Full Schedule & Options
    • Apple Watch > Sleep app > Full Schedule
  • iOS Health > Summary > Sleep: check if the option to "Set Up" is shown.
    • If so, complete the Sleep setup process.
    • If this fails, open the Sleep app on the Watch and complete the setup process there.
  • iOS Watch app > Settings > Sleep > "Track Sleep with Apple Watch" should be turned On.
    • For "in bed" tracking, "Track Time in Bed with iPhone" should be turned On under Health App > Sleep > Full Schedule & Options
  • The Apple Watch should have a sufficient battery charge. If their Apple Watch runs out of battery overnight in their sleep, it is expected that Sleep Tracking may fail.
  • If you have multiple Watches, please ensure Auto-Switch is enabled in the iOS Watch app > All Watches.


Verify Schedule

And one of the following

  • Sleep Schedule set up, and "Use Schedule for Sleep Focus" enabled in Health app > Sleep > Full Schedule & Options
  • Watch Sleep Focus turned on manually for 4 or more consecutive hours


Note: Sleep results ("In Bed" and Sleep Stages data) may take several minutes to come up after disabling Focus > Sleep.

Hello, Mike_P1!


Thank you very much for the detailed reply and for the support tips.


I verified all settings, step by step, as per your suggestions. Everything is OK. Nevertheless, sleep tracking is not OK. Sometimes it's OK (like every few days. For example, yesterday it was EXCELLENT. Spot-on! Then, nothing changed /settings-wise/ and last night Sleep only started tracking after 2:30 am and I went to bed at 23:25h. Sleep focus/schedule is 23:00-7:00). It's all so very RANDOM :( But for many years Sleep was recorded perfectly well. I also used AutoSleep and it worked PERFECTLY well in tandem with Apple Watch. Now it is also totally out of sync. I have now uninstalled it as part of the troubleshooting. I upgraded from Apple Watch 5 to 8 and from iPhone X to 14 pro (almost at the same time, more than a month ago), and for the first 2 weeks everything (sleep-wise) was OK. Then suddenly, overnight (no software OS updates, no settings changed)…all went bananas :(


I'm in touch with Apple Support over the phone for more than 2 weeks now. I have a ticket and a link to always get back to the original support person. The case is ongoing. The issue has been escalated. Support even logs in remotely (screen sharing) to troubleshoot. No success so far.


Thank you and regards,

Kosta

Hi all,


I need to share that I am experiencing the same issue here. I bought a new Apple Watch Series 9 two weeks ago, and sleep tracking also has issues. It worked the very first night after unboxing, and then from the second night, it started to miss the sleep tracking randomly. I am synced with an iPhone 13 pro, but it seems that others have the same problems with sleep tracking regardless of the phone model.

Devices are :

  • Apple watch series 9 (41) with the latest software - 10.0.2. (21R371)
  • Iphone 13 pro with the latest software - IOS 17.0.3

I've tried so far:

  • Sleep Schedules (alone)
  • Sleep Schedules with Focus Mode
  • Sleep Focus shared across devices
  • Sleep Focus NOT shared across devices
  • Changing Sleep Schedules
  • Bluetooth and Wi-Fi OFF/ON (on Apple Watch)
  • Synced with iPhone (Bluetooth and Wi-Fi on)
  • Not-Synced with iPhone (Wi-Fi only)
  • Updating to the latest software (phone and watch)
  • Always have more than 50% on Apple watch before bedtime
  • Aeroplane mode ON/OFF
  • Wearing the Apple Watch slightly above the wrist(not on the wrist knuckle)
  • Also checked multiple comments/threads and videos online about it, however, my readings are still missing from random nights
  • I've also tried pretty much all of the advice steps from the previous few threads on this page, but sleep tracking does not track some nights.

Thank you for your time and consideration.


Regards Kosta Y.


P.S.

What are the odds, my name is also Kosta

Hi SF-,


I'm sorry to hear that you are having the same issues in 2024 with a Series 9  Watch. But don't worry, and do not lose faith. Mine is now working fine like a charm, spot on, correct, and absolutely great. I spent a lot of time with  Support; the issue was escalated several times ("stairs") with no result. I gave up. But apparently, the problem wasn't with the  Watch/Health app at the time. Maybe, maybe a software update fixed things, but if you are having issues a year after my issues, probably it was not a hardware/software thing. I guess the problem was with my HEART. Later that year I had a yearly heart exam with my cardiologist and he said I had a "somewhat" irregular heart rhithm. A few weeks later, I had a full-blown AFIB (which  Watch detected immediately) and stayed this way for a few months (during that time, sleep tracking was not working). But then I got hospitalised, and the doctors performed Cardio Versio on me (a kind of electroshock under anaesthesia) to bring back the normal sinus rhythm - and they did succeed :) After that day,  Watch has been tracking perfectly sleep and everything health-related. So maybe check with your cardiologist if everything is OK with your heart. Good luck and success.

Also I have heard that wrist tattoos (if you have any) can disrupt the collection of data. I literally have the exact same problem. Talked to Apple, they sent me to Best Buy to try and fix it but they couldn’t, Best Buy gave me all these numbers and codes to tell Apple I need an express replacement (because I have AppleCare +) but it costs twice as much as I paid for this watch to make the deposit. They want $399. I might as well get the 9. And THAT is what this is all about. I honestly think this problem has something to do with the fact they’re not selling these watches like they used too. I love mine. And I was very excited to get this. It’s just a Shame…

I have had the same issue. I think I noticed it started a few nights ago when I started listening to YouTube videos with insomnia meditations while I sleep. I’m taking a drug temporarily that gives me some insomnia. I just so happened to notice in my activity tracker that it’s listing the time I was asleep as “Entertainment”. So I wonder if because my phone is registering that I’m in “entertainment” mode that it’s not recording sleep stats perhaps?

Oct 24, 2023 9:05 AM in response to hscottgilbert

Unfortunately, I guess I've learned that you MUST set up an unwanted sleep schedule for it to work. I don't have a set time I need to wake up, but for sleep stages to work, you have to set up a schedule. I listen to podcasts when/if I awake in the night, and that doesn't interfere, I don't think (unless it records the podcast as awake time--even though it puts me right back to sleep).

set up a sleep schedule, and it should start recording again.

I have the same exact issue!

I have Apple Watch 9 with WatchOS 10.1 paired with iPhone 12 iOS 17.1.


It is a new watch, and the sleep tracking for the first 2 nights after unboxing. But, afterwards, there is zero data available.


I have made sure sleep tracking is on (both watch and health app) , and Sleep Mode automatically goes on. My watch is always charged, and I make sure to fit it at my wrist properly.


I sometimes watch a video before sleep and i might fall asleep before it ends, not sure if that would affect anything.


Is this a bug, or am I doing something wrong?

This newest apple update has changed everything. I am so disappointed. I would recommend that if you didn’t update it yet, DO NOT UPDATE.

How can I get my watch back to how it’s been for the last several years? I liked to be able to FIND MY IPHONE without going through multiple stages. I liked seeing the ECG on my iPhone and now it’s hidden. Why does Apple always try to change things and in the process ruins a good thing and what we’re used to. I am quickly losing faith in Apple after the latest update on my watch and the latest update on my IPhone 14 Pro. It may be time to try an Android. Goodbye Apple. It’s your own fault for messing up a good thing. It’s

Apple Watch 8 and iPhone 14 pro, bought at the same time last year. Worked fine collected data every night just fine until a month or so ago I noticed some nights it just says “in bed”. So I’m thinking my health app pulled data from my phone over my watch and that’s why. I turned off collect data from phone while sleeping as in hopes the phone will only pull watch data for my sleep. I’ll try to remember to update if it works.
