Inaccurate sleep tracking after updating Apple Watch to watchOS 26.0.2

With the latest apple watch update 26.0.2, the sleep tracking on my series 8 watch has significantly changed. With the update, it is showing an inaccurate number of wake ups, poor rem and deep times. Total time asleep is not correct. Immediately after the update, the sleep tracking app is showing a significant number of wake ups as compared to the prior results before the update. I suspect the watch is super sensitive and recording incorrectly, wakeups and under reporting Rem and Deep. This is a major reporting change and I am wondering if others in the community have experienced problems with the accuracy and analytics with the latest update. 26.0.2

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’ve just left this on the Feedback report


Since the latest updates on iOS and watch, the sleep tracking is now way off what it used to be. It’s showing way way more awake time. The interesting thing for me is this: I wear a whoop and an Apple Watch 6 in bed and have done both for two years. My subscription with whoop ends in a few months and frankly I was not going to renew as my main target data was sleep. Until now I’d been hugely impressed how similar the data for whoop and sleep in Apple health were, hence me thinking of cancelling. I was going to buy a new watch instead. Unless this is fixed I won’t be
