Mi Band 3: Sleep Tracking Explained

how to use sleep tracking in mi band 3

The Xiaomi Mi Band series is an affordable fitness tracker that can monitor daily activity and health metrics, including sleep. While it is not the most in-depth sleep-tracking solution on the market, it can still provide valuable insights to help you improve your sleep and overall health. To enable sleep tracking on the Mi Band 3, you can use the official Mi Fit app or third-party apps like Sleep as Android, Notify and Fitness, or Mi Band Tools. These apps can provide additional features and more detailed sleep data, such as sleep duration, sleep quality, and sleep trends. However, it's important to note that all fitness trackers have a margin of error, so it's best to focus on general trends rather than spot accuracy when interpreting your sleep data.

Track sleep using the Mi Fit app

To track your sleep using the Mi Fit app, you must first ensure that you are wearing your Mi Band 3 correctly. It should be snug on your arm but not too tight. The Mi Band series uses a built-in accelerometer to detect motion and a heart rate sensor to estimate when you fall asleep.

The Mi Fit app will automatically start tracking your sleep once it detects that you have fallen asleep. The app will record the duration of your sleep, as well as the times you fell asleep and woke up. However, it is important to note that the app may not accurately track the time you wake up during the night unless you are out of bed for more than a minute.

You can also enable assisted sleep monitoring in the Mi Fit app, which increases the heart rate measurement frequency when the Mi Band detects that you are asleep. To do this, open the Mi Fit app and navigate to the Health Monitoring settings. Here, you can toggle on assisted sleep monitoring under the Heart Rate section.

Additionally, if you are interested in tracking your sleep breathing quality, you can enable this setting in the Mi Fit app. This feature uses blood oxygen sensors to monitor your breathing quality during sleep and provide a breathing quality score.

While the Mi Band 3 does not track REM sleep, it can still provide valuable insights into your sleep duration and quality.

Improve sleep tracking accuracy

The Mi Band 3 is a capable sleep tracker, but there are a few things to keep in mind to improve its accuracy. Firstly, it's important to wear the band correctly. Ensure that it is snug on your arm but not too tight. This will ensure the sensors can accurately detect your body movements and heart rate.

Secondly, the Mi Band 3 has specific sleep tracking hours, typically between 10 pm and 6 am. If you go to bed outside of these hours, the band may not accurately track your sleep. Additionally, the band may not detect brief periods of wakefulness during the night, such as when you wake up to check your phone. It tends to only label a time period as "Awake" if you get out of bed and walk around.

To improve sleep tracking accuracy, you can combine the Mi Band 3 with third-party sleep tracking applications like "Sleep as Android". This integration provides more accurate sleep tracking and offers features like smart alarms to wake you up during light sleep. However, this may require installing additional apps, such as a notification and tools app for the Mi Band 3 to work seamlessly with "Sleep as Android".

Lastly, it's important to remember that all fitness trackers, including the Mi Band 3, have a margin of error. Instead of focusing on spot accuracy, it's better to look at general trends over time to gain insights into your sleep patterns. Regularly reviewing your sleep data and making changes to your sleep routine based on the suggestions provided by the Mi Band's sleep quality analysis section can help you steadily improve your sleep.

Track sleep breathing quality

The Mi Band series are capable sleep trackers. Mi Band models with blood oxygen sensors can monitor breathing quality. To enable this feature, you need to open the Zepp Life app. Then, tap the Profile tab, select your Mi Band device under the My Devices section, tap Band settings, and tap on Night mode. Toggle on Night mode, and then select a Schedule turn-on time. Adjust the start and end times.

Assisted sleep monitoring increases the heart rate measurement frequency when the Mi Band detects you're asleep. To enable this, open the Zepp Life app, tap the Profile tab, select your Mi Band device under the My Devices section, tap Health monitoring, and toggle on Assisted sleep monitoring under the Heart rate section.

You can also combine the Mi Band with Sleep as Android to get accurate sleep tracking and smart alarms.

Use third-party apps for sleep tracking

While the Mi Band 3 does have its own sleep tracking feature, some users have reported limitations with the service. For example, it doesn't seem to notice if the user wakes up in the middle of the night unless they get out of bed. Therefore, some people may want to consider using third-party apps for sleep tracking.

One such app is Sleep as Android, which is a popular sleep tracking app that can be used with the Mi Band 3. To enable sensor tracking integration, go to Sleep as Android > Settings > Wearables > Sleep Tracking and check 'Use Wearables'. However, to connect Sleep as Android with your Mi Band, you'll need to purchase another app called Mi Band & Tools. This app will connect your Mi Band to Sleep as Android, allowing you to use the heart rate monitoring feature without needing to keep your phone on your bed at night.

Another third-party app that can be used for sleep tracking with the Mi Band 3 is Notify & Fitness for Mi Band (N&F). This app automatically detects asleep/awake times and properly detects night awake times, which the Mi Band's default sleep tracking feature has been known to ignore.

It's worth noting that some users have reported weird behaviours when using third-party apps in parallel with the default Mi Fit app. Therefore, it may be best to uninstall Mi Fit after pairing your device, or use a third-party app exclusively.

Track sleep using the Sleep as Android app

To track sleep using the Sleep as Android app, you can follow these steps:

First, set up your alarm time by tapping the top right plus icon in the app. Then, tap the desired time directly on the clock, selecting hours first and then minutes. You can rely on the default settings to get started and explore more advanced options later.

To enable sensor tracking integration with your Mi Band, go to Settings > Wearables > Sleep Tracking and check "Use Wearables". You can also adjust the sensitivity of settings like awake detection to optimise your results. If you want to disable awake detection, go to Settings > Sleep Tracking > Awake Detection.

To collect heart rate data from your Mi Band, enable tracking by going to Settings > Sleep Tracking > Wearables > Bluetooth Smart. Try pairing with your device, although this may not be necessary for all devices and OS versions. Ensure that no other apps are using your device during sleep tracking.

If you encounter issues, reboot your phone before sleep tracking and ensure no unnecessary services are running. If the problems persist, send a debug report through the app's support function.
