Fitbit devices have a robust sleep-tracking function that can monitor sleep stages and wake you during light sleep. The Fitbit Charge 2 can track sleep, but some users have reported inconsistencies with the feature. To track sleep, Fitbit devices detect when the wearer's body is completely at rest and hasn't moved for about an hour. The device then records this as sleep. Fitbit's sleep tracking function works best when the device is worn snugly and higher on the wrist.

What You'll Learn
Fitbit Charge 2 accuracy
The Fitbit Charge 2 is a fitness tracker that can monitor heart rate, count steps, track calories burned, and track sleep activity. While the device has been praised for its robust battery life, allowing for simultaneous nightly tracking and daily wear, there are mixed reviews regarding the accuracy of its sleep tracking and heart rate monitoring functions.
Sleep Tracking
Fitbit Charge 2 can automatically detect sleep when worn on the wrist during sleep. The device records an individual as asleep when their body has been completely at rest for about an hour. However, some users have reported inconsistencies in sleep tracking, with the device failing to register sleep at all or providing inaccurate data. It is recommended that the device be worn snugly and positioned higher on the wrist for more accurate sleep tracking.
Heart Rate Monitoring
The Fitbit Charge 2 uses PurePulse technology, a patented PPG technology, to monitor heart rate activity. While some users have found the heart rate data to be accurate when at rest, others have reported inconsistencies during physical activity, with the device underestimating heart rate or displaying delayed updates.
Data Accuracy
The accuracy of the Fitbit Charge 2's data has been the subject of several studies. One study found that the device underestimated heart rate, with a mean bias of -5.9 bpm and wide limits of agreement, indicating that individual heart rate measures could be underestimated by up to 30 bpm. Another study compared the Fitbit Charge 2 to a gold standard electrocardiograph and found an upper limit of agreement of +17 bpm and a lower limit of agreement of -29 bpm. These studies suggest that while the Fitbit Charge 2 can provide valuable insights into heart rate and sleep patterns, it may not be as accurate as medical-grade devices for precise measurements.

Fitbit app
The Fitbit app allows you to track your sleep patterns and quality. To track your sleep with a Fitbit, you'll need a compatible device and the app. Most Fitbit devices can sense when you fall asleep, how long you sleep for, and log detailed sleep data. Wrist-based Fitbit devices and Google Pixel Watch series automatically detect your sleep when worn to bed. Fitbit devices that track heart rate (except Charge HR and Surge) also track sleep stages.
To set up sleep tracking, download the Fitbit app and sync your device. You can then wear your device to bed and explore the details provided by the app. The app will provide a sleep score, a breakdown of your sleep, and tips and advice. The Smart Wake feature monitors your sleep stages and wakes you during a light sleep stage.
It is important to note that the sleep tracking feature is not intended to diagnose or treat any medical condition and should not be relied upon for medical purposes. The placement of your Fitbit can also affect the accuracy of the tracking. For best results, wear your Fitbit snugly and higher on your wrist.

Fitbit sleep stages
Fitbit devices and Google Pixel Watch series can automatically detect your sleep when you wear your device to bed. It is recommended that you wear your device in a snug wristband during sleep. When your body is completely at rest and you haven't moved for about an hour, your device records that you're asleep.
Fitbit fitness trackers and smartwatches have a robust sleep tracking function. All Fitbit devices have sleep-tracking functions that work in the same way and deliver the same information. However, older Fitbit devices that don't measure heart rate cannot deliver information about sleep stages.
Sleep scientists recognize three main sleep stages: REM sleep (where most dreaming happens), deep sleep (a restorative phase for the mind and body), and light sleep (which is essentially the time not spent in REM or deep sleep). The Fitbit app also shows a Sleep Score that's made up of time asleep (50% of the score), the amount of time spent in deep and REM sleep (25% of the score), and restoration (which shows how much of your sleep time is below your resting heart rate, also 25%).
The Smart Wake feature monitors your sleep stages and wakes you during a Light Sleep stage, in a window of up to 30 minutes leading to the time you've set for the alarm. For example, if you set a 7:07 am alarm, your potential wake-up times would range from 6:37 am to 7:07 am.

Fitbit fitness trackers and smartwatches have a robust sleep-tracking function. The Fitbit will automatically detect your sleep when you wear your device to bed. It is recommended that you wear your device in a snug wristband during sleep. When your body is completely at rest and you haven't moved for about an hour, your device records that you're asleep.
The Fitbit sleep settings have two modes: Normal and Sensitive. The normal setting counts significant movements as being awake (such as rolling over) and is appropriate for most users. The sensitive setting will cause your tracker to record nearly all movements as time spent awake. This setting may be helpful for users with sleep disorders or those who wear their tracker somewhere other than their wrist while asleep.
To change your setting in the Fitbit iOS app, go to Account > Advanced Settings > Sleep Sensitivity. To change your setting in the fitbit.com dashboard, go to Settings > Devices > scroll down to Sleep Tracking.
You can also set a sleep goal on your Fitbit. Open the Fitbit app on your phone. Tap on the round icon that may (or may not) have your photo, at the top left of the screen. Tap Activity and Wellness > Sleep > Time Asleep Goal, and use the pull-down menu to adjust your total sleep target. You can also get to this menu by hitting the gear-like Settings icon at the top left of your app's Sleep menu. Set bedtime and wake-up time. In the Fitbit app on your phone, tap on the round icon that may have your photo, at the top left of the screen. Tap Activity and Wellness > Sleep > Bedtime and use the pull-down menu to adjust your target bedtime.
