Cycle Between Your Old and New Apple Watch
Some of us love wearing our Apple Watch 24 hours a day. Unfortunately, that can be hard because the battery is never enough.
Luckily, if you have an old Apple Watch, you don’t have to worry about that. As we mentioned, you can let your iPhone know you have two Apple Watches and then cycle between them, letting you charge your new Apple Watch while still keeping track of your heart rate and other important vitals.
