Sleep tracking is an important feature of many fitness trackers, including the Fitbit Charge 3. This device can monitor your sleep by tracking the length of time spent in each sleep stage, such as light sleep, deep sleep, and REM sleep. It can also detect restless sleep through the way your body moves. To enable sleep tracking on the Fitbit Charge 3, simply wear the device to bed, and it will automatically detect when you fall asleep and wake up. Additionally, you can set up sleep tracking on the accompanying Fitbit app and review your sleep data, including a sleep score and a detailed breakdown of your sleep stages. For more accurate results, it is recommended to wear the device snugly and higher on your wrist.

What You'll Learn
Wear your Fitbit Charge 3 to bed
To turn on sleep tracking with your Fitbit Charge 3, wear your device to bed. It's as simple as that! Your Fitbit will automatically detect when you fall asleep and will continue to track your sleep until it senses that you're awake.
To get the best results, wear your Fitbit snugly and higher on your wrist (towards your elbow). This will ensure the most accurate readings. It's also a good idea to make sure your device is charged to at least 40% before going to bed, as the sleep-tracking feature impacts the battery.
If you have a Fitbit Premium subscription, you can access additional sleep-tracking features. For example, you can receive a monthly Sleep Profile, which provides a detailed breakdown of your sleep. To be eligible for a Sleep Profile, you must wear your device to bed for 14 nights in a given month.
If your Fitbit Charge 3 has a heart rate monitor, it can also track the different stages of your sleep, such as light sleep, deep sleep, and REM sleep. This allows you to see how much time you spent in each stage and at what time of the night.

Check your sleep data in the Fitbit app
To check your sleep data in the Fitbit app, open the app and sync your Fitbit device. Then, follow these steps:
- Tap the "Sleep duration" tile. If it says "Analyzing your sleep", your device's data hasn't synced yet.
- Swipe down to the Sleep timeline graph.
- Press and hold the graph.
- Move your finger left or right to check your sleep stages and time spent in each stage.
- Tap "Benchmark" or the "30-day average" tabs to compare your data with others in your age range and sex, or with your own 30-day average.
- Check your averages for the week or longer periods for certain sleep stats, including hours slept and sleep score.
You can also check your logged naps by tapping the "Sleep duration" tile and then "Other sleep". If you want to edit or delete a sleep log, go to the "Sleep Duration" tile on the "Today" tab and tap the menu icon, then "Edit sleep". Choose the sleep session and tap "Edit".
If you have a Fitbit Premium subscription and a compatible device (Charge 5, Charge 6, Inspire 2, Inspire 3, Luxe, Pixel Watch series, Sense, Sense 2, Versa 2, Versa 3, or Versa 4), you can access your sleep profile on the first of every month. This includes 10 monthly metrics and a sleep animal characterisation of your long-term sleep behaviours.
Additionally, if you have a Fitbit Sense or Versa 3, you can turn on the snore and noise detection feature in the app. This allows your device to track noise, including snoring from you or someone next to you, and provides a summary of your nightly results in a report.

Turn on snore and noise detection
To turn on snore and noise detection for the Fitbit Charge 3, you will need to follow these steps:
Firstly, it is important to note that the snore and noise detection feature is only available for the Fitbit Versa 3 or Fitbit Sense smartwatch users who also have a Premium subscription. Therefore, to turn on this feature, you will need to ensure that you have an active subscription.
Once you have confirmed your subscription, you can enable the feature by going to the Settings app on your Fitbit device. From there, navigate to "Vibration & Audio Settings" and ensure that your microphone is turned on. This will allow your Fitbit to collect noise levels and snore information through its microphone.
After turning on the microphone, you can then enable the snore and noise detection feature. To do this, open the Fitbit app on your smartphone and verify that the Premium tab is visible. Then, navigate to "Activity & Wellness > Sleep > Detect Snoring." Here, you will find a toggle button that allows you to turn on the snore detection feature.
It is important to note that this feature impacts your device's battery life, so Fitbit recommends charging your device to at least 40% before going to bed. Additionally, the feature does not differentiate between your snoring and that of others in the room, so it may include snoring from other people or even pets.

Adjust your sleep sensitivity
Adjusting your sleep sensitivity on the Fitbit Charge 3 can help you gain a more accurate understanding of your sleep patterns and quality. Here's a detailed guide on how to adjust your sleep sensitivity settings:
Understanding Sleep Sensitivity:
Sleep sensitivity on the Fitbit Charge 3 refers to the device's ability to detect and interpret your movements during sleep. It determines whether your movements indicate that you are awake or restless. The device uses a 3-axis accelerometer to track your motion and an algorithm to translate this data into sleep patterns.
Normal vs. Sensitive Mode:
The Fitbit Charge 3 offers two sleep sensitivity modes: Normal and Sensitive. Understanding the difference between these modes will help you choose the right setting for your needs.
- Normal Mode: In Normal mode, the device records significant movements, such as rolling over, as time spent awake. This setting is suitable for most users and provides a basic idea of your sleep patterns.
- Sensitive Mode: Sensitive mode is more detailed and records nearly all movements as time spent restless or awake. This mode is helpful if you often wake up feeling tired, despite your sleep history indicating sufficient rest. It may capture more restlessness, especially if you are a light sleeper.
Adjusting Sleep Sensitivity Settings:
To adjust your sleep sensitivity settings on the Fitbit Charge 3, follow these steps:
- Open the Fitbit app on your mobile device.
- Navigate to the Today tab and tap on your profile picture.
- Go to Fitbit Settings and locate the Preferences section.
- In the Preferences section, tap on Sleep.
- Within the Feature settings section, find and tap on Sleep Sensitivity.
- Here, you can make your desired changes by selecting either Normal or Sensitive mode.
Additional Tips:
- Ensure your Fitbit Charge 3 is sufficiently charged before going to bed. A low battery can impact the device's performance and accuracy in sleep tracking.
- Sync your Fitbit Charge 3 with the app before bedtime. This ensures that any changes made to the settings, including sleep sensitivity, are up to date.
- Experiment with both Normal and Sensitive modes over a period of time to determine which setting best reflects your actual sleep patterns.
- For a comprehensive understanding of your health, combine your sleep data with other metrics such as heart rate, steps, and calorie intake.
- If you have a sleep disorder or specific concerns, consider consulting a healthcare professional to interpret your sleep data accurately and adjust your settings accordingly.
