Apple Watch 8 not Tracking Sleep & Sleep Stages

My watch stopped tracking sleep stages mid January. It now tracks “sleep “ periodically I’ve tried multiple ways to get it functioning, but nothing has work. Apple is growing out of the garden of Eden if it doesn’t figure what’s gone so wrong for so many

Did you get a resolution. I’ve had several watches and several phones but I’ve never had the actual sleep stages show up. It’s always been light blue. So I have no idea what I’m doing wrong. I followed the instructions one response had but my settings were already correct.

Hi Kostadin,

Just seeing your remarks about Apple Watch 8 and checking in to see if your sleep tracking has ever been resolved/fixed?

Would love to know if you found a solution, as I've been experiencing the same thing. Sleep stages randomly show up once every 1-2 wks. Otherwise just seeing a green bar broken up with lots of black space interspersed, not too accurately tracking sleep timing either.

I bought the watch primarily for sleep tracking as I can't wear an Oura ring unfortunately (my knuckles are too large!). But watch seems almost useless.

Thank you!

The only thing that worked for me is to unpair and then repair my Apple Watch. it deletes all corrupt files that you may have.

A backup is made automatically when it up unpair for easy setup when you pair again. Unpair and erase your Apple Watch - Apple Support

You may find this helpful. I use the Sleep app on my watch to track my sleep. It has worked consistently well over several watch versions. To get it:

• Open the Watch app on your iPhone.
• Scroll down to Available apps.
• Tap Sleep to install.

When you wake in the morning, tap AutoSleep on your iPhone to see your sleep data such as what you see in the photo below ... and more. My doctors and I find this very helpful.

I have the same issue. I have an Apple Watch Ultra 2 and I set up sleep tracking last night at about 3am.

It only shows “In Bed”.

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…

As per many comments the Apple Watch stopped tracking my sleep, first stages, now reports s few minutes each night. None of the suggestions on this sight have helped. If anything from Apple is following what is on this site, which they should be to continue to have sales, please correct the issue. If it was from an update, I assume it was not universal, so understanding the etiology and correction may be difficult. But loosing a helpful function is unacceptable

came here with the exact same issue using an Ultra 2 and an iPhone 15 Pro Max

solid sleep bar, no other data

turned off “Track Time in Bed With iPhone” and it now seems to read correctly with REM data etc showing straight after

The two things we care about most: STEPS and SLEEP TRACKING are the most difficult display (for steps, can't keep it on the watch face) and track (functions intermittently for sleep).

If you aren't on a precise schedule, and set a wider 'sleep schedule', it shows you are 'in bed' for the whole range of the schedule. Could deal with that if only the sleep tracking would work consistently.

IT logic is that the app needs to know when to start tracking?

There are few directions anywhere on the apple site. Aside from setting a sleep schedule, can the Bluetooth be off over night? Will the phone store the data until it is again synched with the phone? Should work.

Many thousands of users are having this issue, yet no dedicated and detailed instructions. I keep the bare minimum of apps on the watch to allow focus on the priorities, but still not functional. Would be great if apple could post a reference to any relevant content.

My iPhone stopped going into sleep mode which now requires that I charge 2xs a day

Yea mine worked out of the box then started intermittently tracking sleep! I just want to return it because that’s the only reason I bought it! Very frustrating for the price Apple charges

My Apple keeps stopping from tracking sleep. I have to turn sleep off and back on every night. It is a pain. I’ve had surgery and need to track my sleep. Thinking of going back to wearing my Fitbit

same issue as you all. I have been unable to get it to work. I recently reset my watch to factory defaults and still doesn’t work.
