Inaccurate sleep tracking after updating Apple Watch to watchOS 26.0.2

Yes, I'm also seeing this on my Ultra 2 after the latest watchOS update. Sometimes it shows more than one hour of being awake, just because I checked the time of a a couple of seconds.

All users having the same issue should also report this to Apple directly by using the Feedback link.

Did you use the feedback already to tell Apple about it?

I'm also using the 3rd party app AutoSleep to track my sleep, since I started using the Series 5 four years ago.

This app still shows better results than the new Sleep App on the Ultra 2 in watchOS 26.

And although it uses the same data from the watch, it does not show those completely wrong awake phases.

All users having the same issue should also report this to Apple directly by using the Feedback link, to make them aware of the issue, so that they can address this in an upcoming update.

I prefer using the "Sleep Analysis" in AutoSleep, instead of the "Sleep Stages".

Sleep Analysis does not show the false being awake times that somehow showed up in the Sleep App in watchOS 26.

You can compare the settings to compare them by tapping on ->Sleep Session -> Sleep Analysis.

Then go back to the Clock View.

I did notice some issues prior, in 26.1 and 26.0X but now that 26.2 is public, I’ve had marked improvements in my indoor walk metrics, sleep tracking and scores, as well as the much needed improved battery performance. In fact a whole slew of bugs have been resolved, including some that even persisted prior to the iOS 26 release.

To all those who might have the time, consider joining us in reporting your issues at feedback.apple.com or Product Feedback - Apple this helps amplify the communities voice, and give them a better sense of how widespread the issues may be overall. This also impacts their prioritization when key features require a resolution asap.

I am also having problems with my Auto Sleep data after the 26.0.2 update. The app records me being awake every time I move. It also under records my REM and Deep Sleep. I will be looking for another sleep app if this is not resolved. I did report the problem to Apple and Auto Sleep.

My experience since the latest (October 2025) watch update has been very similar to that reported by aport5. I've used my Apple Watch 7 to track my sleep since I bought it and have been generally happy. Since the latest updates, however, it has been recording quite frequently a high (15-20 at times) number awake times when my actual number has been around 4-7 (this includes my usual 3-5 trips to the bathroom). I've done all the suggested things (makes sure watch and phone are updated, restarted both, ensured watch band is snug, etc) yet the problem continues. Most recently, it told me I slept less than 6 hours when I am sure I slept over 8--something it has done more than once recently. Very disappointed as I have come to value my sleep tracking as a tool to track my overall health.

I have an Apple Watch 7 and after the latest IOS update my sleep score shows weird metrics like less total sleep, several awake times during the night, and overall sleep patterns that are very different than before this update. I don’t know what Apple with their algorithms but it doesn’t appear to be tracking my sleep accurately. This is a problem as I wear my watch under the direction of my physician and sleep is important.

I have not had this problem with the updates. I have the series 9 Apple Watch . In fact my sleep stages have improved due to some changes I’ve made to my sleep hygiene . This is reflected in the health app and I have the data since the update as well as 6 months worth to compare since I do monitor this. My sleep stages have In fact it have improved .

In fact it was sleeping apnea alerts that led me to get a sleep study and then a cpap machine which unfortunately didn’t work for my apneas . But I’m getting to the root cause with numerous dr appointments all thx to Apple Watch whose dx of moderate to severe sleep apnea was more accurate than the sleep studies dx of mild apnea based on the cpap recordings . So I do follow this closely and was honestly shocked by the sleep apnea dx . So you all may be having more interrupted sleep than you realize . It’s not the update .

Since the latest update 26.0.2 the sleep app on my Apple Watch Series 9 is unreliable. It show much less total sleep and almost zero REM sleep even though I remember the vivid dreams I ha e jus t before waking up. The old sleep app worked well and seemed super accurate and track well with what my FitBit used to tell me. Guess I will just have to ignore it. Is there an update to fix this in progress?

This is an example of my data. My watch is a 7.
