Apple Watch 8 not Tracking Sleep & Sleep Stages

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?

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?

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.

This is very frustrating having my Apple Watch Series 8 intermittently tracking my sleep stages and other times not at all and sometimes just a flood bar of green. When is this going to be corrected? This should be addressed in an update to the OS should fix his issue.

I have done all the recommended steps. Sometimes it works for a day or two. Sometimes it doesn’t. It’s really annoying having to do this every night and not know when I wake up if I’ll have the data that I need for all my health apps. I have MS and other ailments and having my sleep stages recorded is very important to me and my doctors

Sleep tracking not working. Have series 8 Hermes, iPhone 13, latest software. Set up sleep in health app on phone. There is no sleep app icon on watch. There is no health app on phone. there is health app in settings, but nothing about sleep.

Apple support (Applecare) is great for run of the mill problems or questions. They are not qualified like the genius bar people and even then--you need to ask for the top guy in the store. Applecare people listen to your problem, then they look it up and read articles on how to fix it. If it's out of the realm of a typical problem, you can't rely on them-- plus their job is to fix the problem there and NOT have you go to the genius bar. Get off AppleCare, they are just trouble shooters not like the geniuses in the store.

Sleep not tracking. I just brought my iwatch 6 and traded it for the iwatch 9. I thought the update for the 6 stopped sleep tracking but the iwatch 9 doesn’t track sleep either.

I see a lot of people are having the same problem. Iphone 13. Iwatch 9. Sleep is set up. Hello!

This explains exactly what I’m experiencing with my brand new version 10.3 just got it at Christmas! I believe my updates are scheduled automatic.

very frustrated! Way too much money for a product not doing what is intended!

Impacts me too :-/ so frustrating. Stops recording sleep or hrv, until I delete all the existing data. Two most important metrics for me. Really makes it pointless to have the watch. iPhone 13 Pro Max plus Apple Watch series 9, both updated software to newest.

I had the same problem. I soon realized that it was the band i was wearing. with the sport one it tracks everything perfectly otherwise with the metallic milanese one it does not stay fit enough to the wrist. hope this helps

The problem is with the software or watch. As with many others, my reports of sleep stopped abruptly, with an occasional partial reading. The fact that Apple has not corrected/addressed this issue in a timely public manner is concerning

SOLVED! Was having same issue too and couldn’t seem to figure it out. Was bothered that I had to set up a sleep schedule and not be able to just nap and have it tracked. Use the right button under the dial and select the moon symbol which was previously the dedicated Do Not Disturb button. Now it gives you two options. Select the Sleep option and it will track and give you stats for when you sleep! You can access the app the see different levels of sleep. Good general info. But if you want more in depth graphs and information, I paid a one time $5.99 (instead of all the monthly subscription based apps) for AutoSleep. Great app. A lot of detailed information. Hope this helped!

Have you tried tightening your Apple Watch band? It could be your watch band is too loose and the Apple Watch thinks you are awake

I just bought the Ultra 2 but going to return it for same issues you have been having. I could not get accurate sleep tracking.
