What You'll Learn
Accuracy of sleep tracking data
The Samsung Galaxy Watch Active 2 has enhanced sleep tracking analysis. It uses your movement and heart rate to determine if you are awake, or in light, deep, or REM sleep phases. This data is tracked in the Samsung Health app, which can be viewed on the watch, but is recommended to be viewed on a smartphone.
The accuracy of sleep tracking data has been a topic of discussion among users. Some users have reported that the sleep tracking feature on the Samsung Galaxy Watch Active 2 is ''horrendous', with inconsistent results when compared to other devices such as the Fitbit Ionic. However, other users have reported a high level of accuracy, stating that the device consistently and accurately records the duration of sleep and detects naps.
It is important to note that sleep trackers have a history of being inaccurate. A 2017 article from The Mayo Clinic mentions that "more than 20 research studies have examined the accuracy and validity of the sleep information they generate, and the results show that the devices are largely inaccurate." However, it is also acknowledged that sleep trackers have likely improved since then. The Samsung Galaxy Watch Active 2 accurately measures sleep for healthy individuals but may lose accuracy for individuals with sleeping problems or when it cannot detect a heart rate. The difference between deep sleep and light sleep is not always accurately tracked.
To improve the accuracy of sleep tracking data, it is recommended to wear the watch correctly. According to Samsung, the watch should be positioned the width of two fingers above the ulna bone on the wrist. A snug fit will improve blood oxygen and heart rate monitoring, which are crucial for accurate sleep tracking. Additionally, features like "Turn on as scheduled" can be activated to ensure that the tracking period aligns with your bedtime and wake-up goals.

Sleep tracking apps
The Samsung Galaxy Watch Active 2 does have sleep tracking enabled. The watch's built-in sleep tracker offers insights on how to get a better night's sleep and also monitors your stress levels. The watch has enhanced sleep tracking analysis and can be used in conjunction with the Samsung Health app.
The watch uses the onboard accelerometer to detect movement and combines this with user data from its sensor array. The watch can also detect body temperature throughout the night, which is used in several other metrics. It is important to note that no fitness tracker is entirely accurate, so sleep data should not be used for self-diagnosis.
The Samsung Health app provides a sleep score, which is a simplified way of understanding your sleep data. The app considers several factors, including total sleep time and sleep cycles, and gives a score between 1 and 100. The higher the score, the better the sleep. The app also provides daily goals and coaching programs to help you form better sleep habits.
To ensure accurate sleep tracking, it is recommended to wear the watch correctly. According to Samsung, the watch should be positioned the width of two fingers above the ulna, the pointy bone on your wrist. Additionally, the watch's bedtime mode should be activated, which disables audio and vibration alerts, except for the alarm.

Sleep tracking settings
The Samsung Galaxy Watch Active 2 has built-in sleep tracking capabilities. The watch can monitor your sleep patterns, track your sleep movements, and provide insights on how to improve your sleep. It also includes REM tracking, which uses heart rate variability (HRV) to help define this period of sleep. To enable REM tracking, open the Samsung Health app on your watch, scroll down to heart rate, tap on the three-dot menu icon, access settings, and choose the "Always" option.
To ensure accurate sleep tracking, it is recommended to wear the watch correctly. Samsung suggests positioning the watch the width of two fingers above the ulna, the pointy bone on your wrist. Additionally, you can set up a sleep schedule using Bedtime mode in the watch settings. This mode disables audio and vibration alerts, except for your alarm, and turns off the always-on display, touch screen, and raise wrist to wake functions. You can also enable Water Lock Mode if you plan to exercise in the water, which will turn off the touchscreen and wake-up gestures and disable the always-on watch face.
It is important to note that the watch's sleep tracking may not always be accurate, especially when you are in bed but still awake. This is because the watch detects a lower resting heart rate and assumes you are asleep. Resetting the watch, ensuring constant HR monitoring, and adjusting the wrist position and tightness may help improve sleep tracking accuracy.
The Samsung Health app also offers daily goals and coaching programs based on your sleep data to help you form better sleep habits. It provides insights into your sleep consistency and how it affects your overall health and sleep health. You can view historical data and compare your sleep score with users in the same age and gender groups. Additionally, the app measures blood oxygenation levels during sleep and provides snoring detection.

Sleep tracking issues
The Samsung Galaxy Watch Active 2 is marketed as having enhanced sleep-tracking analysis. It is advertised as offering valuable insights on how to get a better night's sleep and also monitoring your stress levels. However, there have been numerous reports of issues with the sleep-tracking feature on this device.
Many users have complained that the watch records inaccurate measurements of sleep, with some reporting that it records them as having no deep sleep, and less sleep than they believe they had. One user reported that their watch said they had none, while their Fitbit Ionic said they had roughly an hour of deep sleep. Another user reported that their watch recorded them as sleeping while they were watching a movie, but then didn't record the rest of their sleep for the night.
Some users have tried to remedy the issue by resetting the watch, ensuring constant HR monitoring, and changing wrist position and tightness, but to no avail. It seems that the issue may lie with Samsung's software or sleep-tracking algorithm rather than a hardware issue. One user noted that Samsung Health's way of tracking sleep depth was updated to include an HR variance measure, but this does not appear to have improved the accuracy of the sleep-tracking feature.
In addition, some users have reported that the watch needs to be charged too frequently, which interferes with its ability to track sleep throughout the night.
Despite Samsung's claims of enhanced sleep-tracking analysis, it appears that the Samsung Galaxy Watch Active 2 may not provide accurate or reliable sleep data for its users.
