With the Sleep app 
on AppleWatch, you can create sleep schedules to help you meet your sleep goals. Wear your watch to bed, and AppleWatch can estimate the time you spent in each sleep stage—REM, Core, and Deep—as well as when you might have woken up. When you wake up, open the Sleep app to learn how much sleep you got and see your sleep trends over the past 14 days.
Siri: On Apple Watch Series 9 using watchOS 10.2 or later, say something like: “How much did I sleep last night?” (Not available in all languages or regions.)
If your AppleWatch is charged less than 30 percent before you go to bed, you’re prompted to charge it. In the morning, just glance at the greeting to see how much charge remains.
Note: AppleWatch tracks your sleep based on the sleep schedule you create. AppleWatch can also track your sleep when your Sleep Focus starts. To receive sleep data from AppleWatch, it must track your sleep for at least four hours each night.
You can create multiple schedules—for example, one for weekdays and another for weekends. For each schedule, you can set up the following:
A sleep goal (how many hours of sleep you want to get)
What time you want to go to bed and wake up
An alarm sound to wake you up
When to turn on the Sleep Focus, which limits distractions before you go to bed and protects your sleep after you’re in bed
Sleep tracking, which uses your motion to detect sleep when you wear AppleWatch to bed and the Sleep Focus is active
Note: Sleep tracking is available on watchOS 8 or later.
Tip: To turn off the Sleep Focus, press and hold the Digital Crown to unlock, press the side button to open Control Center, then tap
