Suunto 9 provides three predefined battery modes – Performance, Endurance and Ultra. When starting an exercise, the Performance mode is activated by default. If you define a custom battery mode, the custom mode 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. Here you can as well create a custom battery mode for the sport mode you selected.
Note: Custom battery modes are always specific for one sport mode. This means you can define a separate custom mode for each sport.
To better understand the battery saving concept of your Suunto 9 – especially for setting a custom mode – we created a list of settings and features with their impact on battery life:
High impact on battery life
Medium impact on battery life
Note: You will find an additional Heart rate setting in the Options menu (see screenshot below). When deactivating this heart rate setting (toggle is grey) no heart rate will be measured.
Small impact on battery life
