Battery life and charging
Depending on your usage, your battery life may vary:
• If you aren’t tracking runs or exercises that use GPS, your fully charged Surge
should last up to 7 days as a fitness watch with continuous heart rate tracking
and activity tracking.
• Your fully charged Surge can track a maximum of about 10 hours of activities
that use GPS before needing a charge. To ensure that you’re always tracking
your data, we recommend charging your Surge after any activity that uses
GPS.
Determining your current battery level
When looking at the Menu, your tracker’s battery level appears in the top left.
Full Partially Full Very Low Critically Low Charging
If your battery is critically low, charge your Surge as soon as possible.
You can also check your battery level from the Fitbit app, or by logging into
fitbit.com and clicking the gear icon on the top-right corner of the page. In these
cases, the battery level shown reflects the last time you synced your Surge. To make
sure you are seeing the current battery level, sync your Surge.
