How do I get the most out of the Suunto 9 battery modes?

Suunto 9 offers four predefined battery modes – Performance, Endurance, Ultra and Tour. When starting an exercise, the Performance mode is activated by default. If you define a custom battery mode, the custom one will be activated by default. You can quickly switch modes by pressing the upper right button while in the exercise start display.

The battery modes have the following settings, which can be viewed below the exercise start display, under Options - Battery modes. You can create a custom battery mode for the sport mode you selected as well.

Note: Custom battery modes are always sport mode specific, meaning you can define a different custom mode for every sport depending on your needs.

To better understand the battery-saving concept available on your Suunto 9 – especially for creating a custom mode – we created a list of settings and features and their impact on the watch's battery life:

High impact on battery life
  • GPS accuracy: Best. To save battery: Set accuracy to Good.
Medium impact on battery life
  • GPS accuracy: Good or OK
  • Display always on. To save battery: Set the Display timeout after 10 seconds.
  • Display in full-color mode. To save battery: Activate Low color mode.
  • Wrist HR on. To save battery: Use a chest HR belt.

Note: You will find an additional Heart rate setting in the Options menu. When deactivating this heart rate setting, the watch will not measure the heart rate. By default, Ultra and Tour mode disables all HR tracking (both wrist and chest). To enable HR tracking (in Ultra and Tour mode), go to Options under the start indicator.

Low impact on battery life
  • Touch on. To save battery: Disable touch display.
Additional battery saving tips:
  • Backlight ON has a high impact on battery life. To save battery: Set the Backlight toggle to normal (grey) in the Options.
  • Low surrounding temperatures may shorten the battery life of your watch.
