Fitbit Not Tracking Sleep (Let’s Fix It!)

Fitbit smartwatches and activity trackers are among the best watches that can help monitor your every night sleep. Unfortunately, as much as Fitbit Watches can monitor sleep there are times when they may track sleep inaccurately or worst of all fail to track sleep. So, what’s the reason behind Fitbit not tracking sleep?

In summary, you are not tracking sleep because Fitbit has developed a system glitch, the sensors on Fitbit are covered with dirt, you didn’t sleep enough (you took a nap), the Fitbit app and device need to be updated, Fitbit is low on charge, there is a syncing problem, or you haven’t placed Fitbit properly on the wrist.

The good this is, that all the possible causes/issues summarized above can be addressed to fix the problems and get Fitbit to start tracking sleep. Without wasting time let me briefly discuss the above reasons and give solutions to get your Fitbit to start tracking sleep.

7 Possible Reasons Why Your Fitbit Won’t Track Sleep

1. Your Fitbit Might Have Developed a System Glitch

Fitbit Watches tend to misbehave when they run non-stop. This misbehaving could be because of a system glitch, which in turn causes the watch to fail to track important vitals, e.g. sleep.

If a system glitch or error is making your Fitbit not track sleep accurately or not track sleep at all, try restarting it.

After restarting Fitbit catch some sleep and check if your sleep data was collected and sent to the app the next day.

Don’t know how to restart a Fitbit tracker? Well, it’s easy; follow the simple steps below:

  • To restart (normal soft restart) your Fitbit simply go through the process of shutting down, which is swiping down from the top of the screen, tapping on Settings, scrolling down to the Shutdown option, tapping on it, and confirming the shutdown. Once the Fitbit is off, wait for about 10 seconds and then press and hold the side button to turn your Fitbit back on. That is it! You’ve successfully restarted your Fitbit and it should resume tracking your sleep.

2. There is a Syncing Problem

Fitbit might have tracked your sleep last night but did not send the data to the Fitbit app because of sync issues, which left you thinking it didn’t track sleep. Check the phone and watch to ensure they are successfully connected via Bluetooth so that sleep results from the watch can get to the Fitbit app.

3. The Sensors on Your Fitbit are covered with Dirt

If you turn your Fitbit over, you will see tiny lights that flash green (these are the sensors!). For Fitbit to arrive at your sleep report the next morning it must combine your movements with your heart rate thus an important measure of sleep.

You need to make sure these sensors are clean so that the green light can light through to the skin to track the heart rate.

That is it! Just clean the sensors at the back of the device to get Fitbit to start tracking sleep more accurately.

4. You Did Not Sleep Enough

You did not get your sleep report the next morning on the Fitbit app because you didn’t sleep enough.

Fitbit will only start to record your sleep once it detects you have not moved a muscle for about an hour.

Therefore, it is possible you took a nap and Fitbit Watches are not designed for naps. To get Fitbit to track your sleep the next night you sleep make sure you go to bed a little earlier than usual.

5. The Fitbit App and Device Need to be updated

Fitbit will update its app and device software more frequently to fix bugs and security issues as well as enhance usability.

Fitbit Versa 2, Inspire, Charge 4, and Charge 5 may fail to track sleep accurately or completely fail to track sleep because you are using the old Wear OS or version of the Fitbit App.

You need to update your Fitbit Versa 2, Inspire, Charge 4, or Charge 5 to start tracking sleep.

You can update the Fitbit app by heading to Google Play or Apple Store, searching for the Fitbit app, and tapping the update button.

On the other hand, to update your Fitbit Versa 2, Inspire, Charge 4, or Charge 5 make sure it is charged then:

Go, and tap the Fitbit app on your paired phone > Tap on the My Today tab > Tap your Profile > Select the image of your Fitbit > Tap the pink Update button (this button only shows when an update is available for download) > Proceed with the on-screen instructions keeping the watch close to the phone.

That’s it wait until your Fitbit is updating and you should resume tracking your sleeping soon.

6. You Did Not Place Fitbit Properly on the Wrist

It is possible you placed the watch loosely on the wrist and then went to bed. Remember, Fitbit needs to constantly track your heart rate and movements throughout the night to come up with your sleep report the next morning. To this point, I think Fitbit did not track your sleep last night because your heart rate was not monitored.

To fix this, you need to make sure the watch is properly tightened so that the sensors constantly your heart rate for a more accurate sleep report.  

7. Fitbit is Low on Charge

Your Fitbit has problems tracking your sleep because the battery has run low. Fitbit will stop tracking activities such as sleep to conserve charge. Therefore, make sure you have charged your Fitbit 3 hours before going to bed so that it stores enough charge to keep track of your sleep throughout the night.
