Sleep Tracking: Galaxy Active 2'S Hidden Feature

The Samsung Galaxy Watch Active2 is a smart watch that offers enhanced sleep tracking analysis. It uses motion and heart rate to determine if the user is awake or in light, deep, or REM sleep phases. The data is tracked in the Samsung Health app and can be viewed on the watch or a smartphone. The watch also offers auto workout tracking, pace coaching, and stress monitoring. While some users have reported issues with the accuracy of the sleep tracking, others have found it to be consistently accurate. The watch has received positive reviews for its design, features, and value for money.

The Galaxy Active 2's sleep tracking accuracy

The Samsung Galaxy Watch Active2 has a built-in sleep tracker that offers insights on how to improve your sleep. The tracker monitors your sleep by measuring your movement and heart rate to determine whether you are awake or in light, deep, or REM sleep. This data is then recorded in the Samsung Health app, which can be viewed on the watch or smartphone.

The Galaxy Active2's sleep tracking feature has received positive reviews from customers, who report a high level of accuracy. One customer mentions that the only downside is the short battery life, which only lasts for 2 days, making it impossible to track sleep if charged at night.

While the sleep tracking feature on the Galaxy Active2 is impressive, it is not perfect. Occasionally, the tracker may mistake a person's stillness while working at a desk for the start of sleep. To address this, the tracker uses your movement and heart rate to differentiate between being awake and the different stages of sleep.

In addition to sleep tracking, the Samsung Health app also provides insights on blood oxygen levels during sleep. This feature, introduced in 2021, allows users to monitor their blood oxygen saturation while sleeping, providing valuable information about their sleep quality and overall health.

Overall, the Samsung Galaxy Watch Active2 offers a comprehensive sleep tracking experience with advanced features like blood oxygen monitoring and insights on improving sleep habits. While the short battery life may be a drawback for some, the watch's sleep tracking accuracy and insights make it a valuable tool for those seeking to improve their sleep hygiene and overall well-being.

Sleep tracking with the Samsung Health app

The Samsung Health app, when paired with a Galaxy Watch or Fit, can be used to monitor your sleep. The app provides a sleep tile, which allows you to view your sleeping time, record your snoring, and use sleep coaching options to help you get a better night's sleep.

To use the sleep tracking feature, you will first need to enable it in the Samsung Health app. Open the app on your watch and navigate to Settings, then tap Sleep. Here, you can turn on the Blood Oxygen during sleep feature, which will measure your blood oxygenation levels while you sleep. You can also turn on Snore Detection, which will record and alert you to any snoring during the night.

Once you've enabled the necessary settings, wear your watch to bed, ensuring it is securely attached to your wrist. Place your phone on a stable surface near your head, preferably with the bottom of the phone facing you. The next morning, you can check your sleep data by opening the Samsung Health app and tapping the Sleep tracker. Here, you can view your sleep time, sleep score, sleep stages, blood oxygen levels, and snoring data.

It is worth noting that the accuracy of sleep tracking may vary. Some users have reported issues with the app incorrectly identifying awake moments or not recognising when they got out of bed. However, updates to the Samsung Health app and watch firmware have reportedly improved the accuracy of sleep stage detection and fixed deep sleep tracking issues.

The sleep coaching feature within the Samsung Health app can provide guidance and tips to help you improve your sleep quality. To use this feature, you will need to wear your watch and track your sleep for at least seven days and nights. The sleep coaching settings can be adjusted from your phone, where you can answer questions about your sleep to determine the best coaching options.

Comparing sleep tracking data to other devices

The Samsung Galaxy Watch Active2 has a built-in sleep tracker that offers insights on how to improve your sleep. It also monitors your stress levels and integrates with the Calm app. The watch's long-lasting battery can go for more than a day on a single charge.

When comparing sleep tracking data to other devices, it is important to consider the different metrics and features offered by each device. For example, the Galaxy Watch Active2 provides valuable insights on sleep patterns and stress levels, while other devices may offer more specific metrics such as heart rate, blood oxygen levels, and body temperature.

The Oura Ring, for instance, is a popular sleep tracking device that provides comprehensive data and daily guidance. It measures respiratory rate, heart rate, heart rate variability, blood oxygen levels, and body temperature. The Oura Ring Gen3, in particular, has been found to accurately log sleep patterns when compared to sleep journals and has shown improved accuracy in validation studies.

The Whoop 4.0 is another highly regarded sleep tracker that offers detailed data and health metrics. It provides sleep cycle tracking, blood oxygen monitoring, skin temperature sensing, and heart rate tracking. Whoop's smartphone app allows users to access in-depth information about their sleep patterns and overall health.

Other devices, such as the Apple Watch and Fitbit, also offer sleep tracking capabilities. The Apple Watch provides insights into time in bed, sleep time, heart rate, respiratory rate, and temperature, although Apple notes that these metrics are not intended for medical use. Fitbit devices have been found to accurately detect sleep onset and track sleep cycles, although they may overestimate the time spent in different sleep stages.

When comparing sleep tracking data across devices, it is important to consider the specific metrics and features offered by each device, as well as the accuracy and reliability of the data. Additionally, personal preferences, such as the device's form factor, comfort, and battery life, may also influence the choice of sleep tracker.

The Galaxy Active 2's battery life

The Samsung Galaxy Watch Active2 has a long-lasting battery life that can go for more than a day on a single charge. This is great for users who want to track their sleep continuously without having to worry about the watch dying halfway through the night. The watch can also be quickly charged using a compatible Galaxy phone with wireless power share. However, some users have reported that the battery only lasts for about 2 days, which can be inconvenient for those who want to track their sleep every night.

The Samsung Health app, which is used to track sleep on the Galaxy Watch Active2, has a feature called "blood oxygen during sleep" that tracks blood oxygenation levels. This can be useful for those who want to monitor their blood oxygen levels during sleep to ensure they are getting enough oxygen. The watch also uses motion and heart rate data to determine the different stages of sleep, including Awake, Light, Deep, and REM sleep. This data is automatically uploaded from the watch to the Samsung Health app, which can be viewed on the watch or a smartphone.

While the long-lasting battery life of the Galaxy Watch Active2 is convenient for sleep tracking, it is important to note that the accuracy of sleep tracking may vary. Some users have reported issues with the accuracy of the sleep tracking data, especially for individuals with sleeping problems or when the watch cannot detect a heart rate. Additionally, the watch may record periods of wakefulness during the night, such as when the user is looking at their phone, as part of the total sleep time. These periods of wakefulness can be deducted from the "Actual sleep time" in the Samsung Health app.

Overall, the Galaxy Watch Active2's battery life is designed to last for more than a day, making it suitable for continuous sleep tracking. However, it is important to consider the accuracy of sleep tracking data and the potential impact of factors such as heart rate detection and periods of wakefulness during the night.
