Suunto 5 provides three predefined battery modes – Performance, Endurance and Tour. You can also create a custom battery mode for the sport mode you selected.
When starting an exercise, Performance mode is 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.
Note: Custom battery modes are always specific for one sport mode. This means you can define a separate custom mode for each sport.
Note: When using Endurance mode, make sure to use a heart rate belt to get heart rate data for your exercise. Learn how to pair a belt in the user guide for your product.
