How is the sleep schedule cycle counted? Lets say I want to go to bed in the night from Sunday to Monday at 2 am (Monday morning) is that then the sleep schedule for Sunday or Monday ?
 
What I really don't like that you have to setup a sleep schedule for the watch to track your data during sleep.
 
Ok. I have tested it a few nights now & it performs pretty great.

One criticism though, it won't track your sleep beyond your schedule. Last night it noticed that I struggled to get to sleep, which was true. And then I notice the graphic is kinda fall short to the right (yellow rectangle). It doesn't fill the whole area.
Last night I slept way beyond my alarm (5.30 AM), woke up at 7.40 AM. The watch didn't include this extra data even though it knows when you actually wake up (that's why there is a blank area).

So I checked the day before - I woke up at 4.30 AM that night, 1 hour before my alarm - and the graphic fills the whole area.

So any data beyond your sleep schedule will not be included & that means your 'Time Asleep' (including REM, Core, Deep) - in red circle in 1st photo - will be incorrect unlike the previous iOS which always counted it & was correct.

I work from home so it's super easy to adjust wake up alarm to compensate for this. I suspect many people wouldn't be able to. Hope Apple fix this.

My weekend sleep schedule is set at 11am but I got up close to 12+ in the noon. The sleep data includes my awake and core sleep past 11am.

It will count night, not morning. Sunday night instead of Monday morning.

Do you have alarm turn on?

The alarms I have do not fall under the Sleep/Wake category. It’s an independent alarm I have within the Clock app. Alarm went off at 10.45am but I kept snoozing it and turned it off. Sleep data recorded through 12+ noon.

ok,,you don’t have sleep alarm turned on then. I’ll try this. Thanks.

It’s strange Apple couldn’t make it work for people who have sleep alarm turned on. It used to work in previous iOS. The sleep time & wake up time were always correct.
 
A warning to those who gets up before your wake up schedule.

Do not turn off Sleep on your watch!
You will lose sleep data.

Turn off Sleep on your iPhone. It will ask you to turn off alarm. Once you do that you're good.
Is there anyway to recover this lost data? :(

I have two missing nights of sleep from the last week, I assume due to this issue. It’s frustrating not to have a read on all nights.
 
it won't track your sleep beyond your schedule.

But I work in different shifts, so that schedule is something totally random.

setup a sleep schedule for the watch to track your data during sleep.

I gave up on the Apple Sleep app due to having to set a schedule (although maybe there is a way to avoid that), didn't seem to track naps, etc.

Anyone who can’t have sleep schedule there’s always AutoSleep.

Am now testing AutoSleep. Seems to be a much more flexible program. There's a "Lights Off" button which starts sleep tracking and runs a HomeKit scene if you wish. Seems also able to handle naps.
