How to save battery life on Apple Watch during workouts

By default the Apple Watch constantly monitors your heart rate during workouts, which consumes extra battery life.

While some kinds of workouts require consistent heart rate data in order to track calorie burn rates more accurately, it isn't necessary for all kinds of workouts. That's why the Apple Watch gives you a way to disable consistent heart rate tracking during certain kinds of activities. In turn, you get a little more battery life out of your Apple Watch. Here's how!

By performing the steps below, your Apple Watch will not consistently monitor your heart rate during walking and running workouts. It will continue to monitor heart rate on a constant basis during any other kind of workout. And if you ever decide you want more frequent heart rate data during a specific run or walk, you can always re-enable the setting on the fly whenever you'd like.
