Wear your watch to bed, and Apple Watch can track your sleep. 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. If your Apple Watch is charged less than 30 percent before you go to bed, you’re prompted to charge it.
When you call a dead phone does it ring?
