Sleep score hours seem very "off" compared to the old system recorded by the Apple Watch and read on the Health app. What could be occurring?

When does the sleep score timing start? Does it not allow sleep timing ot start before one sets their bedtime alarm?

I find that I have been asleep for more than 4 hours, have just woken from a dream, and the blue color has not even been recording for 2 hours. The sleep score is off compared to the original system that preceded it. Does anyone know why the new system gives me very different information?

Yes, on my Ultra 2 as well. If I go to bed earlier than the Sleep Schedule, my sleep statistics show a nap.

Same if I sit at the table after breakfast and read my newspaper, another nap recorded.

All affected users should all let Apple know about this issue by using the Feedback link, I have already submitted mine.

This is the only way to make Apple Techs aware of issues.

The watch band should not be worn too tight. I do not change the fit of my watch band before sleep, wearing it as comfortable as during the day. Except during workouts, since the weight of the Ultra 2 pushes it towards the wrist, where the heart rate sensor might lose the signal.

The sleep feature is useless. If you take a nap, that’s all that’s recorded. Results seem to be a day behind. I slept for 7 hours, but only an hour was recorded. If you wake up at all, recording stops. Very disappointing.

Yes, I was. It seemed to give me mostly useful info until updated to the sleep score. I reset it and see if that might help with recording tonight. I don't need to know much more than how many times I wake up at night and how many hours I slept.

Thanks, though. I will reset and see if that works better today. I might try a tighter watch band, too. If that doesn't work, I have a leather one that may be looser than the silicon; perhaps it loosened around my wrist at the same time as the update.
