Fitbit Charge 3's sleep tracking feature is called Sleep Score beta
The Fitbit Charge 3's sleep-tracking feature is called Sleep Score Beta. This feature provides a detailed analysis of your sleep quality. It is calculated based on multiple factors, including your heart rate, the time spent awake or restless, and your sleep stages.
Sleep Score Beta assigns a score to your sleep on a scale of 0-100, with a score of 90 and above considered "excellent", and anything below 60 deemed "poor". This score is influenced by three subcategories: Sleep Duration, Sleep Depth, and Revitalization. Sleep Duration compares your goal sleep duration to your actual sleep time. Sleep Depth assesses your deep and REM sleep against the average ranges for people of the same age group and gender.
The Fitbit Charge 3 not only measures how long you have slept but also identifies the different stages of sleep you experienced, including REM, light, and deep sleep. It is important to note that the device needs at least 3 hours of sleep data to estimate these sleep stages accurately. The sleep tracking feature also allows you to manually adjust your sleep log if the start or end times are incorrect.
To enhance the accuracy of the Revitalization score, it is recommended to wear your Fitbit Charge 3 throughout the day. This enables the device to collect heart rate and SpO2 data during the day, providing a more comprehensive comparison with your sleep data. The Sleep Score Beta also includes a series of questions about your mood, energy levels, and habits before sleeping, such as caffeine or alcohol consumption and exercise routines.
