How can I save battery life on my Apple Watch during workouts? You'll need to go into the Apple Watch app on your iPhone.

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.

How to conserve on Apple Watch battery life during workouts

  1. Launch the Apple Watch app on your iPhone.
  2. Tap on Workout.
  3. Tap the *Power Saving Mode switch**. Green means power saving mode is turned on.

    Launch the Apple Watch app, tap on Workout, and then turn on the option for Power saving mode.

You can also save your battery life by using accessories: An external Bluetooth heart rate monitor will save the watch from having to take heart rate readings during exercise, as will bringing your iPhone with you on walks or runs if you have a Series 2 Apple Watch (so as to avoid active GPS use).
