Suunto 9 offers four predefined battery modes – Performance, Endurance, Ultra 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: With Good and Ok GPS accuracy (used in Endurance and Ultra mode), the Running and Trail Running sport modes will activate FusedTrackTM , to provide a good track even with lower GPS points and battery consumption
Note:Battery mode selection is memorized in the watch. The last battery mode you selected with a specific sport mode will be suggested to you the next time you launch that same sport mode.
Note: Custom battery modes are always sport mode specific, meaning you can define a different custom mode for every sport depending on your needs.
