What You'll Learn
Fitbit Charge 2 sleep tracking accuracy
To activate sleep tracking on the Fitbit Charge 2, you must first sync your device with your phone. To do this, download the Fitbit app and turn on Bluetooth on your phone. Then, click on the Profile icon on the top left of the app, click "Set Up a Device", and select your device. Make sure your device is fully charged and confirm by hitting "Next". A four-digit code will appear on the watch face, which you will need to enter into the app.
Now, to the topic of sleep tracking accuracy. The Fitbit Charge 2 can automatically detect and track your sleep. It does this by measuring your breathing and heart rate to determine when you fall asleep, when you enter different sleep stages, and when you're restless. The sleep stages it can track are light, deep, and REM sleep, as well as time awake. The accuracy of the Fitbit Charge 2 in tracking these sleep stages has been assessed in studies, with results indicating low to medium strength of correlation and room for improvement.
One study compared the Fitbit Charge 2's sleep and heart rate estimates to polysomnographic measures in a group of shift workers, including police officers and paramedics. The results showed slightly lower accuracy for light sleep and higher accuracy for deep and REM sleep. The study also found that the Fitbit Charge 2 had a small underestimation of heart rate, with a limited ability to capture sudden changes due to lower time resolution compared to polysomnography. However, the underestimation was smaller during sleep stages N2, N3, and REM.
Another important factor in sleep tracking accuracy is the placement of your device. To accurately track your sleep, the Fitbit Charge 2 should be positioned higher on your wrist, about 2-3 finger widths above the wrist bone. It should be secure but not too tight. Additionally, it is recommended to have at least a 40% charge on your device before going to bed to avoid missing data.

Fitbit Charge 2 sleep tracking troubleshooting
Sleep tracking is a feature available on the Fitbit Charge 2. If you are having trouble activating sleep tracking on your Fitbit Charge 2, there are several troubleshooting methods you can try.
First, ensure that your Fitbit is charged. The Fitbit app on your smartphone can give you insights into your health and heart rate data, but these features impact your device's battery life. It is recommended that you charge your Fitbit to at least 40% before going to bed. If your Fitbit's battery runs out during the night, some data will be missing from your sleep report. If your Fitbit is not tracking your sleep, try charging it and performing a restart. To restart, press and hold the button on your Fitbit for about 8 seconds, until the Fitbit logo appears on the screen. After releasing the button, allow the device to power on completely, then check if the sleep tracking feature is functioning.
If your Fitbit is charged and has been restarted, but is still not tracking your sleep, make sure that your device is positioned correctly on your wrist. The band should be worn about 2-3 finger widths above the wrist bone, and it should feel secure but not too tight. If your Fitbit is still not tracking your sleep, try updating your firmware. If the update does not work on your mobile device, log into your Fitbit account on a different mobile device or computer and try the update again.
If your Fitbit still fails to track your sleep, you may want to try resetting your device. In the Fitbit app, go to the "Sleep" section and ensure that Sleep Tracking is turned on. If it is, and your Fitbit is still not tracking your sleep, you may need to reset your device and set it up as new.
It is important to note that the sleep tracking feature on Fitbit is not intended to diagnose or treat any medical condition and should not be relied on for medical purposes. For specific questions about your health, consult a healthcare professional.
