Finished your day and want to charge your Fitbit Versa, Sense, or other Fitbit model, but you’re not seeing any indication that the battery is charging? Getting just a blank screen–and now it looks like your Fitbit isn’t charging at all?

Before you conclude that your Fitbit battery has died, check out our troubleshooting tips. Your Fitbit’s problem might be a faulty charger, bad or wrong power source, bent or missing contacts, or even a dirty charging port. 

Sadly, not charging is one of the most common issues that Fitbit users face. So if you find yourself in this situation, don’t worry!

In this post, we go through some steps you can take to troubleshoot the problem and get your Fitbit charging again. These tips work for all Fitbits, not just the Versa and Sense series.

Quick checklist

  • Make sure you charge your Fitbit without using it or interrupting it for at least 30 minutes.
  • Clean both the contacts on your Fitbit’s backside and the charging cable. Use a sanitizing wipe or microfiber cloth to remove anything stuck to the pins, like grease.
  • Verify you are placing the Fitbit correctly on the charging pins–when perfectly aligned, it snaps into place.
  • Inspect the charger for any bent, missing, or recessed pins. This is a big problem with the chargers for Versa 3+ and Sense series–the pins on the charging cable should be even.
  • Check that there are no metal objects, like jewelry, near your Fitbit when it charges–these can interfere with the magnetic charging capabilities.
  • Try a different USB port or a wall outlet. Don’t use a keyboard’s USB port or a hub’s ports–these often do not have sufficient power to charge your Fitbit.
  • Remove any other devices plugged into the same power source that’s charging the Fitbit. 
  • For new Fitbits, check that you removed the clear plastic protective cover from the back of your Fitbit and the charging cable.

Check if your Fitbit actually is charging

If, after placing your Fitbit on its charger, the screen goes dark and black, it might look like it’s not charging. However, in most cases, it is indeed charging.

Fitbits do not continuously show charging status on-screen when charging to conserve power. Instead, you see a black screen.

To check if your Fitbit is actually charging, for watches, tap its screen twice to turn the screen on temporarily.

For trackers like the Inspire or Charge Series, tap the screen once to check its charging status.

Your Fitbit shows the current battery level for a few seconds, then goes dark.

Fitbit says not charging. Not enough power from the source message?

If you face this issue with your unit or see the more common “no power at source” message or “not charging, not enough power detected from source,” first check the back and sides of the watch and look for signs of a swollen battery.

If you see any bulging and bowing, it looks warped, or anything abnormal, or you see other signs that your battery is swollen, contact Fitbit support.

Do not attempt to charge or use the Fitbit if it looks swollen.

Try different power sources for charging your Fitbit

If the back of your Fitbit looks normal, verify that you seated the Fitbit on its charger correctly. Take the Fitbit off its charger and reseat it–you should feel it snap into place when installed correctly.

If you connect any other devices to that same power source, unplug them and try charging your Fitbit again.

Once you connect everything properly, move your Fitbit charger to a different power outlet, a power bank, or a USB port.

Then, try charging again.

Don’t use a USB hub or USB port on your keyboard–these often don’t support charging your Fitbit.

To ensure it’s not an issue with the cable, try using a different USB cable with the charger, if applicable, to see if it helps.

It’s always worth checking out the charging ports and ensuring that you don’t have any debris or dirt stuck in them.

Clean the charging ports

One of the first things you should do is make sure the charging ports on both your Fitbit and charging cable are clean.

Over time, dust and debris accumulate in these ports and prevent the device from charging properly. 

So give your Fitbit a good clean, and don’t forget to clean the charging contacts.

Gently use a soft, dry toothbrush or a cotton swab to clean the charging ports to make sure you don’t damage any of the components.

  • Using a soft toothbrush or interdental brush to clean the charging contacts on your Fitbit device and its charger is okay.
    • But don’t use anything that scrapes the contacts, as it often causes damage to the plating and makes them vulnerable to rust and corrosion.
  • If needed, use a small amount of isopropyl alcohol on a cloth and then clean the contacts.
    • Check that you are not missing any battery contacts–you should see the same number of contacts on both the device and the charger.
    • If contact is missing, you may need a replacement charger or device–reach out to Fitbit Support.
    • You can also purchase a third-party charger for your Fitbit.
  • Once you clean your Fitbit (the module itself), put it on the charger and charge it for several hours.

Check the charging cable

If your Fitbit still isn’t charging, the next step is to check the charging cable.

Make sure it’s securely plugged into both your Fitbit and the power source. Try using a different USB port or wall adapter to see if that helps. And if you have a spare charging cable, try using that as well to see if the issue is with the cable itself.

  • It is also a good idea to ensure that your tracker is connected securely to the charging cable.
    • Loose connections can also cause the trickling charge issue on your Fitbit Watch.
  • Check your charger for missing, stuck, pushed in, or bent pins. The charging cable for the Fitbit Versa 3/4 and Sense series seems particularly vulnerable to pins recessing into their holes.
    • To charge your Fitbit, it must make contact with all 4 pins—so take a close look and check that all the charging cable’s pins make contact with your Fitbit. 
    • If a pin seems like it’s pushed in, take a pair of tweezers and gently pull it into position with the others, so all pins are equal. 
    • If you discover that the charger’s pins are the problem, contact Fitbit Support or purchase a replacement charging cable.

Was your Fitbit Versa completely discharged to 0%, or have you not used your Fitbit in weeks/months/years?

Connect your charger to a wall outlet instead of a computer’s USB port. If your wall outlet doesn’t have USB ports, you need to use an adapter to charge directly from a wall outlet.

Then, leave your device on the charger for at least one hour (preferably more) before attempting to turn it on.

Restart to fix Fitbit charging issues

If cleaning and checking the charging ports and cable doesn’t work, try restarting your Fitbit.

To restart most Fitbits, press and hold its side button(s) for around 15 seconds until you see the screen turn back on with the Fitbit logo or another icon (like a smiley face.) This action turns it off and then back on again. Once it’s turned on, try charging it again.

  1. Start by shutting down and restarting your Fitbit.
  2. Restarting your watch reboots the device but doesn’t delete any data (see this article for how to restart other Fitbit models).
  3. You can restart your Versa and all Fitbit smartwatch models by going to Settings app > About > Shutdown. Wait 20 seconds, and then turn your Fitbit back on.
    1. For the Fitbit Sense series, Versa 3/4, Versa Lite, and Fitbit Versa 2, you can also hold the side button for 10 seconds until you see the Fitbit logo on the screen.
    2. For the original Versa, press and hold the back (left) and bottom buttons until you see the Fitbit logo on the screen. This should take less than 10 seconds.


    3. Let go of the buttons and let it startup.
  4. After the restart, try charging it again.

Reset your Fitbit

If the simple restart did not solve the issue, the next step is resetting your Fitbit back to its factory settings and then trying again. A factory reset of your device removes all your personal data–so be prepared to start fresh!

Resetting erases all data from your device, so make sure you’ve synced your data to the app before resetting, if possible.

To reset your Fitbit, on most devices, go to the Settings menu > About menu > Factory reset and follow the instructions. Once you reset the Fitbit, try charging it again.

  1. For older model Versas, press and hold all three buttons for 15 seconds or so until the Fitbit logo appears–SOMETIMES THIS CAN TAKE A FEW MINUTES.
      1. Release the bottom right button
      2. When it vibrates, release the remaining buttons.

To reset other models, see this article: Need to restart or reset your Fitbit device? Learn the steps

Restart or resetting not helping?

If you have already tried the restart/factory resetting multiple times to no avail, your best bet is to reach out to Fitbit support and request that they send you a replacement charger.

Fitbit Versa owners have a good chance that Fitbit Support provides you with a free replacement charger since the problem is widely known.

If you are pressed for time or find a backlog for replacement chargers for the Fitbit Versa Series, look at our recommended chargers and give one of those a try.

There are many chargers available out there for less than $10.

Stick to the Fitbit brand or certified

Of course, Fitbit advises users to stick with the official Fitbit charger instead of a third-party one. The description should say “Official Fitbit Product.”

However, by using one of these cheaper replacement chargers, you can confirm that the issue is not with your Fitbit Watch but the charging cradle itself.

And while we have recommendations for third-party chargers for your Fitbit Versa Series, we always advise you to read through user reviews to see if the product is the right fit.

Can I use an old Fitbit charger from a previous Fitbit?

Every Fitbit model has a different design and size, so each has a unique charger. And consequently, most new Fitbits can’t charge on an older model. 

For example, you cannot charge a Fitbit Versa 3/4 or Sense series using the Versa 2’s or the original Versa model’s charger. And vice-versa, you can’t charge a Versa (original) using a Versa 2 or 3/4’s charger.

However, the Fitbit Sense series and Versa 3/4 use the same charger, so you can use these interchangeably!

Can I get my Fitbit battery replaced?

Sadly, Fitbit does not provide a battery replacement service like Apple for its wearables and hearables.

Officially, Fitbits can not have their batteries replaced. However, many electronics repair shops do replace Fitbit batteries. You can find these locally or online.

Or, if you like doing it yourself (DIY), you can purchase battery replacement kits for your Fitbit online and then open your Fitbit and replace it yourself.

Be warned that replacing a Fitbit battery requires soldering the new battery to the existing wiring. This process is a bit too technical and complicated for most of us!

In that case, we recommend contacting Fitbit customer service. And if they cannot solve your battery issues, they usually offer a discount on a replacement Fitbit (if out of warranty.)

Contact Fitbit Support

If none of these steps work, it’s possible that there’s a hardware issue with your Fitbit. In this case, you should contact Fitbit Help for further assistance.

The support team may be able to provide additional troubleshooting steps or help you set up a repair or replacement for your device.

Wrapping it up!

In conclusion, if your Fitbit isn’t charging, there are several steps you can take to troubleshoot the problem.
