Galaxy Gear S2: Can It Track Your Sleep?

The Samsung Galaxy Gear S2 is a smartwatch with a range of features. One feature that has been added through a software update is sleep tracking. The sleep tracking functionality uses the device's integrated heart rate sensor to detect three different stages of sleep: restless, light, and motionless. The data is then analysed and pushed through a complex algorithm to calculate the total time slept and the number of calories burned. While some users have reported that the automatic sleep tracking function is convenient and accurate, others have noted that it requires a lot of setup and uses a lot of battery power.

Sleep tracking capabilities of the Samsung Gear S2

The Samsung Gear S2 does have sleep-tracking capabilities, but this feature was only added with a software update in July 2016. This update brought a host of new features to the Gear S2, including social sharing for activities and a new 'Contacts' app.

The sleep-tracking functionality uses the device's integrated heart rate sensor to detect three different stages of sleep: restless, light, and motionless. It then analyses the data and pushes it through a complex algorithm to calculate the total time slept and the amount of calories burnt. This data can be viewed on the S Health app, which can be accessed on the watch or via a smartphone.

The sleep-tracking feature on the Samsung Gear S2 seems to be well-regarded by users, with some describing it as "scary accurate". The ability to view sleep data on the wrist is convenient, and the Trends option in the S Health app allows users to identify any similarities between their recorded sleeps.

However, it is worth noting that some users have reported that the sleep-tracking feature is not automatically enabled and requires a manual start from the S Health app. Additionally, there are alternative third-party apps available, such as Sleep as Android and GNight, which can be used for sleep tracking on the Gear S2. These apps may offer more detailed insights into sleep patterns and can also record sounds, such as snoring.

Using the S Health app to track sleep

The Samsung Gear S2 does have sleep-tracking capabilities, but only after a certain update. If you have a Gear S2, you can update the firmware to the latest version (R730XXU2DPFB) to access the sleep-tracking feature.

To use the S Health app to track your sleep, you will first need to update your Gear S2 to the latest firmware version. Once updated, the sleep tracking should be automatic, and you will be able to view your sleep data in the S Health app on your smartphone.

The S Health app will show you the total time slept, and you can also view a comprehensive history of your sleep since you started using the feature. It will also show you any trends or similarities between your recorded sleeps. The sleep tracking functionality uses the device's integrated heart rate sensor to detect three different stages of sleep: restless, light, and motionless. It then analyses the data and calculates the total time slept and the amount of calories burned.

You can also use third-party apps such as Sleep as Android or GNight for sleep tracking, which integrate with the S Health app as a "companion app". However, these apps may require additional setup and may use more battery power.

Sleep tracking apps for the Samsung Gear S2

The Samsung Gear S2 does have sleep-tracking capabilities, thanks to a major software update that was rolled out in 2016. The update added several new features to the smartwatch, including a sleep tracker. The sleep tracking functionality utilizes the device's integrated heart rate sensor to detect three different stages of sleep—restless, light, and motionless. It then analyses the data and pushes it through a complex algorithm to calculate the total time slept and the amount of calories burned.

While the sleep tracking feature is now built into the Samsung Gear S2, there are also third-party apps that can be used for sleep tracking. One such app is Sleep as Android, which integrates with the S Health app as a "companion app". Sleep as Android tracks sleep with graphs and also records sound, such as snoring. Another standalone app that can be used for sleep tracking on the Samsung Gear S2 is GNight, which costs $2.

The accuracy of the sleep tracking feature

However, there are also reports of inconsistencies in the sleep tracking data. One user noted that if they woke up in the middle of the night and went back to sleep, the device would log it as two separate sleep periods, which could skew the efficiency rating.

To enable sleep tracking on the Gear S2, users may need to update their firmware to the latest version and utilise third-party apps such as Sleep as Android or GNight. These apps integrate with the S Health application as "companion apps" to facilitate sleep tracking. It is worth noting that some users have reported that these apps can be cumbersome to set up and may consume a significant amount of battery life.

The benefits of sleep tracking

The Samsung Galaxy Gear S2 does have sleep-tracking capabilities, but it's important to note that this feature was added later through a software update.

Now, onto the benefits of sleep tracking. Sleep tracking can provide valuable insights into your sleep patterns and help you understand your sleep cycle, including the different stages of sleep you experience, such as deep sleep and REM sleep. This information can help you identify any irregularities and make informed decisions to improve your sleep quality. For example, by analyzing your sleep data, you can determine if you're getting enough deep sleep and make adjustments to your sleep habits to enhance your overall sleep quality.

Sleep trackers can also help identify potential sleep disorders, such as sleep apnea, by monitoring your heart rate, body temperature, breathing patterns, and movement. Early detection of sleep disorders allows you to seek medical advice and treatment, which can improve your overall health. Additionally, some sleep trackers provide personalized recommendations to enhance your sleep environment, such as adjusting room temperature or reducing noise levels.

Sleep tracking can also help you reflect on your sleep habits and make you more mindful of them. By tracking your sleep, you can identify patterns and factors that may be disturbing your rest, such as caffeine intake, stress levels, or inconsistent bedtimes. This awareness can empower you to make positive changes to your routine and improve your overall well-being.

It's important to keep in mind that sleep trackers don't directly measure sleep. Instead, they often estimate sleep based on inactivity or movement. If you're anxious about your sleep quality, sleep tracking might cause unnecessary stress. However, for those who struggle with sleep or want to optimize their sleep habits, sleep tracking can be a valuable tool to gain insights and make informed decisions for better rest.
