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

It’s important to note that any major update such as this latest iOS 26 might yield results that alter performance of key areas that will need proper adjustment. I’ve spent many years as a developer release beta tester, and can tell you with certainty that they take these issues very seriously, and fixes are for the most part addressed in an orderly, expedited fashion. That probably doesn’t help your frustration, but it is fair to say this issue won’t be left on the back burner indefinitely.


I’ve noticed some questionable results with my ultra 3, but since my sleep patterns are not consistent or like a typical persons- I’m not entirely surprised by my own numbers; that said there could be some that are not perfectly inaccurate.


I will report the issue as well and I do know they are aware of these forums and the issues presented here- often reaching out to those users who post experiencing such problems.


Switching to an Aura ring, in my opinion at least, might not be the best use of your money, but to each their own. Choose a store with a robust return policy in case you don’t get the accuracy or consistent performance you’ve come to expect.


With regard to new releases, I suggest waiting 1-3 months before updating after a major release to iron out these such issues. Long gone are the days where smartphones were minimalistic, basic app function devices. Today, they are the equivalent to a powerful computer. And as they continue to expand in design, ability and functionality, especially with external hardware and sensors, bugs and bug reporting and fixing are a very real part of the evolutionary process.

Again, these aren’t things  just ignores indefinitely. There is a robust beta testing community, and we too take that work as volunteers very seriously.


I do hope at least some part of this will help ease some part of the stress you (and others) might be experiencing. It may not be the reply you’d prefer to hear right now, but it is the truth. And that, in my mind, is a step in the right direction forward.
