Depending on your usage, your battery life may vary:

A fully charged Frontier X can last ~ 24 hours in Monitor Mode

Typical usage mode : Assuming 1 hr usage per day: 14 days (approx.)

Your fully charged Frontier X should last 14 days if used for an average of 1 hr/day.
Your fully charged Frontier X can track a maximum of about 24 hours of activities, before you need to download your data and charge the device
For optimal usage, we recommend charging your Frontier X when the battery level goes below 20%.

We also recommend connecting your device to a charger when you do a Cloud Transfer over Wifi, since this process consumes a lot of power.

To charge your Frontier X, plug the charging cable into the USB port on your computer and plug the other end into the port on the side  of the Frontier X device. You can also plug your charging cable into any standard USB wall charger. Charging the device from 0 to 100% will take about 3 hours. 

When looking at the Menu, your Frontier X’s battery level appears in the top left. 

When you press the red button on the Frontier X once, the third screen will show you the battery level on the left, and the total memory consumption of the device on the right.
