Forerunner Battery Life
Battery
Life*
Forerunner Use
1 week You are training for 45 minutes
per day with GPS. The
Forerunner is in power save
mode for the remaining time.
Up to 4 weeks You are using the Forerunner
in power save mode the entire
time.
Up to 8 hours You are training with GPS 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.
Power Save
After a period of inactivity, the
Forerunner goes into power save
mode and appears. The Forerunner
displays the time and date, but does not
connect with your ANT+ accessories
or use GPS. Swipe left to exit power
save mode.
Maximizing Battery Life
Extensive use of screen backlighting
can signicantly reduce battery life.
