Naturally, the Workouts app burns a ton of battery life on Apple Watch. It constantly uses the heart rate sensor, GPS, and cellular (if you’re away from your iPhone). This could be an issue if your Apple Watch battery is running low but you need to fill in your Activity rings, still.

Follow along to learn how to enable power saving mode while within the Workouts app.

Apple Watch: How to enable power saving mode for the Workouts app

  1. On your iPhone, head into the Watch app. Scroll down to Workout.
  2. Toggle Power Saving Mode up top.

With power saving mode, Apple Watch will disable cellular and heart rate sensing entirely. GPS will still be available for outdoor activities. Apple notes that calories burned with this mode may be less accurate. Bluetooth-enabled external heart rate monitors will not be affected.
