Why isn't my Fitbit device's battery charging?

Most charging issues can be resolved using the recommended solutions below.

First, check the table for common issues. If these recommendations don’t resolve the problem, proceed to the step-by-step troubleshooting section.

Troubleshoot common issues

Issue or error	Recommended solution
The screen is totally black.	Plug it into a wall outlet for 60 minutes. Tip: Do not plug it into a computer.
The error "insufficient power source" appears.	Unplug other gadgets from your USB hub or use a different wall plug.
The charger won't stay attached.	Check if the little gold pins on your cable are stuck or dirty.
The battery dies in less than a day.	In your watch settings, turn off Always On.
There’s a big red "X" on the screen.	This indicates a sync or software error. You'll need to remove and re-add your Fitbit device in the app. For more information, refer to Step 4: Resolve the red "X" sync error.

Step 1: Give your Fitbit device a deep clean

Even if the gold contacts on the back of your watch appear clean, a thin and invisible layer of sweat or lotion can block the electrical current.

• Clean the contacts: Gently clean the gold dots on the back of the watch and the pins on the charger with a cotton swab and rubbing alcohol.
• Remove stubborn buildup: If it still won't charge, use a pencil eraser to firmly rub the gold dots on the back of your Fitbit device. This safely scrubs away the buildup that alcohol can't reach.
• Clear debris: Brush away any eraser bits completely before plugging the device back in.

Step 2: Check your power source and cable

1. Plug your charging cable into a standard wall outlet.
2. Leave your device on the charger for a full hour.

   Tip: If your Fitbit battery is completely at 0%, the screen might stay black for several minutes when you first plug it in.

3. Unplug the cable and use your finger to gently push the gold pins on the charging cable.
4. Verify that they spring back up immediately. If a pin stays pushed in or feels stuck, your cable likely needs to be replaced.

Step 3: Restart your device

Important: Restarting your device will reboot the hardware, but won’t delete any of your fitness data.

For most fitness trackers (Charge 5, Charge 6, Luxe, and Luxe Special Edition)

1. Connect your device to its charging cable.
2. Locate the small button on the flat end of the charging cable.
3. Press the button 3 times, pausing for exactly 1 second between each press.
4. Wait roughly 10 seconds for the Fitbit logo to appear on the screen.

For smartwatches (Sense and Versa series)

1. While the watch is connected to the charger, press and hold the physical side button for 10 seconds.
2. Once the Fitbit logo appears on the screen, release the button.

Step 4: Resolve the red “X" sync error

If a red "X" appears on your screen, your device's software has frozen during a data transfer.

1. Open the Google Health app .
2. At the top right, tap your Profile picture or Initial.
3. Tap Remove this device.
4. Open your phone's Bluetooth settings, then find your device. 
5. Tap Forget or Unpair.
6. Go back to the Google Health app , then tap Set Up a Device.
7. Follow the on-screen instructions to pair your device back to your account.
