How do I determine how much power is left on the battery?
The battery icon on your watch screen displays the remaining level of power in the battery.
Workout time remaining (approximate)
|Battery icon||ProSense 17||ProSense 57|
|8 to 13 hours||6 to 10 hours|
|5 to 8 hours||4 to 6 hours|
|2.5 to 5 hours||2 to 4 hours|
|0 to 2.5 hours||0 to 2 hours|
When the battery is low, you see this screen:
(Press any button to return to the Time screen.)
When the battery is too low, the screen may go blank.
Charge your watch at least once every 6 months when you are not using the watch; long-term storage of the watch with a low battery may degrade battery performance.
Note: Operation time also varies depending on the operating environment's effects on GPS reception and watch settings, such as backlighting.
When you are not using the watch for a workout, the remaining operating time for your watch varies, depending on the features enabled on your watch.
