Using your One
Wearing your One
The Fitbit One is most accurate when worn on or very close to your torso. A clip
designed to keep the tracker secured to your clothing is included in your package.
A sleep wristband for your Fitbit One is also included in your package. The wristband
should be worn while you sleep. It should not be worn for tracking during the day.
To prevent losing your tracker, wear it:
1. In your pocket.
2. Clipped on your pocket, facing inwards.
3. Clipped on your bra.
The Fitbit One is sweat-proof and rainproof. It is not waterproof and should not be
taken swimming.
Battery life and power
Battery life
Your One contains a rechargeable Lithium-ion polymer battery.
With normal use, your One’s battery should last approximately two weeks before
requiring a charge.
You can check your tracker’s battery level by logging into your Dashboard and
clicking on the gear icon in the upper right corner of the screen. The battery level at
the time of its most recent sync will be listed to the right of the picture of your One.
Charging your One
Charge your One tracker by plugging your charging cable into a USB port and then
inserting the tracker into the charger, making sure the gold contacts on your tracker
align with the gold dots in the charging cable.
