How to Fix Sync Issues for a Fitbit Charge 2

Authored by: Support.com Tech Pro Team

1. Introduction

Syncing is the process that transfers the data your Fitbit device collects to your Fitbit dashboard. The Fitbit dashboard is where you can track your progress, see how you slept, set goals, log food and water, challenge friends, etc. Fitbit devices typically use Bluetooth Low Energy (BLE) technology to sync with phones, tablets, and certain computers. If you are having issues syncing your Fitbit device, this guide will take you through troubleshooting steps to help get things back on track.

2. Restart Device

1. Plug the charging cable into the USB port on your computer or any USB wall charger.
2. Clip the other end of the charging cable to the port on the back of the tracker. The pins on the charging cable must lock securely with the port.
   

1. Make sure the button on your tracker is aligned with the button opening on the charging cable.
   

1. You will know the connection is secure when the tracker vibrates and you see a battery icon on the display. Your Charge 2 will begin charging.
2. Press and hold the button on your tracker for four seconds. When you see the Fitbit logo and the tracker vibrates, this means the tracker has restarted.
3. Unplug your tracker from the charging cable.
