Turn Your Old Apple Watch Into a Dedicated Sleep Tracker

On the other hand, if you don’t mind wearing an Apple Watch while you sleep, you can turn your old device into a sleep tracker. Of course, your new Apple Watch can also do this, but this way, you won’t lose battery life overnight.

Your old Apple Watch will help you monitor your heart rate and other important vitals while you sleep. It will also let you track your quantity and quality of sleep via the Health app.

The best part is that you can also use the old Apple Watch as an alarm clock. It’s way harder to ignore an alarm clock when it’s constantly vibrating on your wrist, so your old Watch could help you always be on time from now on.
