Forerunner Battery Life
Battery 
Life*Forerunner Use
1 week

minutes per day with 
GPS. The Forerunner is in 
power save mode for the 
remaining time.
Up to 3 
weeks You are using the 
Forerunner in power save 
mode the entire time.

*The actual battery life of a fully 
charged battery depends on how much 
time you use GPS, the backlight, 
and power save mode. Exposure to 
extremely cold temperatures will also 
reduce battery life.

Forerunner prompts you to go into 
power save mode. The Forerunner 
displays the time and date, but does not 
connect with your heart rate monitor 
or use GPS. Press
