If your Fitbit only shows you the sleep stages data but doesn’t tell the duration, awake time, or sleeping heart rate, your Fitbit premium subscription has ended. 

But if Fitbit doesn’t even track the sleep stages and sleep quality, then it means there is a problem with the optical heart rate sensor. 

The optical heart rate sensor and movement sensor (accelerometer) simultaneously measure users’ sleep. Any fault in this sensor will make Fitbit stop tracking sleep. 

But you don’t need to fret! Below are some of the fixes to get out of this problem.

1- Make Sure That Heart Rate Sensor Is Working Fine

As I mentioned earlier optical heart rate sensor in Fitbit is the primary element that tracks sleep stages. 

So if it works fine, everything is fine. That’s why you must first ensure that the optical heart rate sensor is working fine. 

You can conduct a heart rate test to check whether the Fitbit is tracking accurate readings. In case you find any fault in the heart rate sensor, you need to reset it.

  • Open Fitbit’s Setting app
  • Scroll to Heart Rate 
  • Tap on Turn off, and wait for 30 seconds. 
  • Now restart your Fitbit, and again turn on the Heart rate.


Now again, check whether the heart rate sensor is working fine or not. 

2- Dry Moisture From Your Fitbit

The heart rate sensor also causes malfunctioning if water penetrates it. 

Stop! And think for a moment: did you bring your Fitbit for swimming? Or Did you take a shower with your Fitbit? Maybe shampoo, conditioner or such chemicals enter into the Fitbit.  

If such chemical or water penetrates your Fitbit, you must first dry it out.

Place your Fitbit under sunlight for 30 minutes, and then grab the hair dryer to wipe further moisture. 

3- Restart The Fitbit 

If the optical heart rate sensor is working fine, but sill your Fitbit is not tracking sleep, it means there are some software glitches. 

The defective cache sometimes causes these glitches and prevents Fitbit from tracking your sleep data. 

In such a scenario, you should restart your Fitbit. This will solve all the software-related issues, syncing, and tracking problems. 

The restart process is different for each Fitbit model. You can hover over this guide to see how to reset your Fitbit tracker. 

4- Reconnect Your Fitbit With Fitbit App

So first, you need to unpair your Fitbit. 

  • Grab your phone and open the Fitbit app. 
  • Now tap on your profile picture from the top left corner. 
  • Tap on your Fitbit tracker that you want to unpair. 
  • From the top right corner, tap on the trash icon. 

Now your Fitbit is disconnected from your phone. Once the watch is unpair, you need to restart your watch before connecting it again.

  • Tap on Setup device, and select your Fitbit from the list. 
  • Now it will ask you for permission to sync data; tap on Allow. 
  • Next, the app will ask you to enter the code on your Fitbit screen. 

Hopefully, this time the Fitbit will seamlessly track your sleep data. 

5- Update The Fitbit OS

The outdated Fitbit OS can cause syncing or connectivity problems which stops Fitbit from tracking sleep. 

Fitbit frequently launches new updates to eliminate bugs and give a seamless experience to users. Not only that, but the new Fitbit OS also brings new features to motivate you. 

By default, Fitbit OS automatically update if your Fitbit is connected to the internet. But you can also manually update the Fitbit firmware.

6- Don’t Wear Fitbit To Loose

Fitbit’s heart rate sensor only works best when it’s in contact with your skin. Otherwise, it won’t get the signals from your arteries and hence can’t log the sleep data. 

So whether you have Fitbit Sense, Versa, Charge, or Inspire, it’s mandatory to don’t wear it too loose on your wrist. 

Secondly, make sure there is two fingers difference between your Fitbit and wrist bone. Before bed, lose your Fitbit so it can move easily on your wrist and not block blood circulation. 

To get the best results, it’s recommended to wear Fitbit on your non-dominant hand because the movement of this hand is comparatively more than dominant hand. 

That’s why the accelerometer detects your movement better during the night and gives more precise sleep data. 

Similarly, wearing Fitbit on your ankle or arm is not a good idea. Fitbit is only made for your wrist and gives accurate readings on it. 

7- Reset Fitbit To Its Factory Settings

If you are getting tied and none of the above methods works for you, then it’s time to reset your Fitbit to its factory setting. 

The factory reset will clean all the data from your Fitbit app. But surely, this will solve all the software-related issues and glitches. 

Here are steps to rest the Fitbit; 

  • Open the Setting app on your Fitbit
  • Go to Device Info
  • Tap on Clear user data. 

Wrap Up 

Sleep tracking is a must-have feature in your Fitbit that helps you to improve your sleep habits and build discipline. 

It’s very annoying when Fitbit stops tracking sleep; at that time, it seems your Fitbit is useless. But don’t fret; you can easily fix the issue using the above mentioned methods. 


Is Fitbit sleep tracking accurate?

Yes, Fitbits accurately measure your bedtime and awake time. But the sleep stages data is somehow accurate. But compared to competitors like Garmin, Apple Watch and Samsung, Fitbit has reliable sleep tracking. 

How Fitbit tracks sleep data?

Fitbit tracks sleep data using the accelerometer sensor and optical heart rate sensor. 

With the help of an accelerometer, Fitbit guesses your bedtime, awake time and total sleep time. Where optical heart rate sensor tells the heart rate patterns during sleep, and Fitbit uses this data to measure sleep stages.

Why is my Fitbit not tracking my sleep correctly?

There are several reasons why Fitbit don’t track sleep correctly. But most of the time, the main reason is an incorrect place of Fitbit. 

Wear Fitbit on your non-dominant hand, and don’t wear it too loose or tight.
