How do I charge my Flex?

Last updated: Jan 02, 2014 01:24PM

Fitbit Flex has a rechargeable battery that generally lasts for 5 days. For more information about the Flex's battery, see Tracker battery information. For troubleshooting, see My tracker's battery isn't charging.

To charge your Flex, do the following:

  1. Remove your tracker from the wristband: 
  2. Insert your tracker into the charging cable. Line up the tracker with the charging cable, putting the rounded end of the tracker into the charging cable at a slight angle. Use your thumb to push the tracker in and down into the charging cable until you hear a click.
  3. Insert the charging cable into a USB port or UL-certified USB wall charger. 
  4. Your Flex's LED indicator lights will pulse to show the battery level every few seconds.
    Each solid indicator light represents progress towards the total charge. It may take up to 3 hours to fully charge your Flex. When it's charged, all 5 indicator lights will blink.
  5. You can then take your tracker out of the charging cable and insert it into your wristband. 
Sorry about that.
