What You'll Learn
Sleep tracking features
The Samsung Galaxy Watch offers reliable, easy-to-use, and free sleep-tracking features. The watch can monitor your sleep patterns, sleep time, sleep stages, blood oxygen levels, snoring, and sleep consistency.
To track your sleep, you need to wear your watch to bed and ensure that sleep tracking is enabled. You can do this by opening the Samsung Health app on your watch, swiping to Settings, and tapping the switch next to Blood Oxygen during sleep to turn it on. You can also set up sleep tracking on your phone by opening the Samsung Health app, navigating to Settings, and turning on Blood Oxygen during sleep.
Once sleep tracking is enabled, the Galaxy Watch will monitor your sleep patterns, including the number of sleep cycles and the percentage of sleep that is interrupted. It will also track your blood oxygen saturation levels during sleep, providing the minimum saturation percentage and the total time blood oxygen saturation was under 90%. This data can give you insights into your fitness and wellness, although Samsung notes that it should not be used for diagnosis.
In addition to tracking blood oxygen levels, the Galaxy Watch also offers snore detection. This feature uses your phone's microphone to record audio snippets of your snoring, allowing you to determine the intensity and duration of your snoring. The watch will also monitor your sleep time, showing you how long you spent sleeping and the number of calories burned.
The Galaxy Watch also provides a sleep score, which indicates how well you slept. This score is based on various factors, including sleep time, sleep stages, and blood oxygen levels. The watch will also show your sleep consistency, indicating the number of days in the current week that you have achieved your set sleep goals.

Sleep score
The Samsung Galaxy Watch 3 features a sleep score that rates your sleep quality on a scale of 0 to 100. This score is based on several factors, including the total time asleep, time spent in different sleep cycles, movements, and physical and mental recovery. The watch can distinguish between multiple sleep periods, scoring them separately if your sleep is interrupted.
Samsung defines specific parameters for each of the factors that contribute to the sleep score. For instance, adults should have between 3 to 7 sleep cycles per night to achieve a high sleep score. A sleep cycle refers to the progression through the four stages of non-REM and REM sleep, typically lasting around 90 minutes. The ideal percentage of interrupted sleep is between 10% and 40%. Physical recovery, associated with deep sleep, is considered excellent when it reaches 40% or higher. Mental recovery, linked to REM sleep, contributes to a high sleep score when it surpasses 60%.
While the numerical score provides an objective assessment of your sleep, Samsung does not initially provide a descriptor for the number, making it challenging to interpret whether your score is good, average, or poor. However, the Galaxy Watch 6 and One UI 5 Watch introduced word-based scores and sleep symbols to accompany the numeric values, offering clearer interpretations. Additionally, the Samsung Health app presents sleep data in chart and graph form, including a timeline of your latest sleep spell and a breakdown of sleep stages.
The Galaxy Watch 3 also offers sleep coaching options to guide you toward healthier sleep patterns. To utilise this feature, you must wear the watch for at least seven days and nights, and the settings can only be adjusted from your phone. The sleep coaching program provides personalised recommendations by assessing your sleep patterns, goals, and habits through a series of questions.

Blood oxygen tracking
The Samsung Galaxy Watch series offers blood oxygen tracking during sleep. This feature is available on the Samsung Health app on your watch or phone. To enable it, open the Samsung Health app, go to Settings, and turn on Blood oxygen during sleep. The watch will then display your blood oxygen percentage when you wake up.
It is important to note that blood oxygen saturation data is influenced by external factors such as temperature and how well the watch fits on your wrist. Therefore, while it can provide valuable insights, it should not be used for diagnosis. Instead, it can help you understand your body's response to various activities and environments.
The Galaxy Watch's ability to track blood oxygen levels during sleep is a significant step forward in health monitoring. By providing information about your blood oxygen saturation levels, the watch empowers you to take a more proactive approach to your health and well-being. This feature, combined with the watch's sleep tracking capabilities, offers a comprehensive view of your sleep quality and overall health.

Snore detection
The Samsung Galaxy Watch series offers a Snore Detection feature that records and notes the sounds you make while sleeping. This feature is available for the Wear OS 3 models, like the Galaxy Watch 4 and above, that use the Samsung Health app version 6.18 and above. The snoring detection feature uses your phone's microphone, so you must be near your phone while sleeping. To optimise the feature, Samsung advises users to place their phone's microphone facing them to pick up on any snoring and identify how long and often they snore.
The Samsung Health app will display your Snore Detection data the following morning. To access this, open the Samsung Health app on your phone and tap the Sleep tracker. Then, swipe to and tap the data under Snoring. The watch will record exactly when snoring took place and the audio will help determine how intense the snoring was.
The Snore Detection feature is part of the Sleep tile on the Samsung Health app, which also includes data on your sleep score, sleep time, sleep stage, blood oxygen during sleep, and sleep consistency. To use the Snore Detection feature, your Wear OS Galaxy Watch must be connected to your phone via the Galaxy Wearable app.
The Galaxy Watch5 and Galaxy Watch5 Pro have improved sleep tracking and coaching features that guide users through healthier sleeping patterns and provide reports to help them track their progress. This includes data on sleep time, score, stages, blood oxygen, and snoring.
