Causes of a Fitbit Not Turning On

There are many Fitbit models, including bands and smartwatches, but all Fitbit devices tend to suffer from the same glitches. Often, a Fitbit device won't turn on because of a drained battery, a problem with charging, or it might be affected by a software error. Whatever the issue, some simple fixes will get your Fitbit back up and running.

How to Fix Your Fitbit

Here are some easy troubleshooting steps to try on your Fitbit device. Try each troubleshooting step in the order presented here for the best chances of fixing your Fitbit quickly.

  1. Clean the Fitbit. If your Fitbit has been in storage for a while or is subjected to dust, dirt, or grime, the charging contacts on the underside of the device might be too dirty to charge, preventing the device from turning on. Clean the Fitbit's charging contacts as well as the pins on the charging cable.

    Cleaning the Fitbit's band may not help the device charge, but it will keep it looking like new.

  2. Fully charge the Fitbit. Charge the Fitbit for a minimum of three hours before using it. Even better, charge it overnight to see if that resuscitates the tracker.

  3. Ensure the Fitbit charges correctly. Your Fitbit might not be getting enough power to charge its battery. Plug the Fitbit's charger into an AC wall adapter and ensure the computer stays awake for several hours while the Fitbit charges.

  4. Restart the Fitbit. Like any piece of tech that misbehaves, restarting your Fitbit might clear up any glitches and get the device back up and running.

    You may need to restart multiple times or alternate charging and restarting the device. Fitbit might need a restart to get to a point where it can accept a charge, but it might not yet be recovered enough to turn on.

  5. Perform a factory reset of the Fitbit. If you restart and charge your Fitbit three times and it doesn't respond, reset the Fitbit back to its like-new factory conditions.

  6. Contact Fitbit customer support. If these troubleshooting steps don't work, there may be a hardware problem with your Fitbit. Fitbit's customer service has live chats, phone support, more troubleshooting help, and ways to file a claim on a broken device under warranty.

FAQ
  • Why is my Fitbit vibrating but not turning on?

    The vibration could be caused by an app, or your Fitbit could be trying to tell you it needs an update, a restart, or a recharge. Plugging in and restarting your Fitbit should take care of the issue.

  • Why won't my Fitbit turn on when I turn my wrist?

    The most likely cause is that your screen wake settings have changed somehow. Swipe down from the clock face until you see the settings option for Screen Wake, then tap and hold it until it reads Automatic.

  • Why does my Fitbit only work when it's charging?

    Your Fitbit's battery is probably dead or dying. You can't replace the battery without voiding the warranty, and you'll also need some expertise in servicing electronics. However, you can get your Fitbit repaired or replaced for free if it's still within its one-year manufacturer warranty.
