Snore detection
The Galaxy Watch 5 offers a Snore detection feature, but it is not enabled by default. To set up snore detection, open the Samsung Health app on your phone and go to the Sleep tile. Tap the three-dotted icon on the screen to open up the settings, then tap Snore detection and select to turn it on Always or just Once per "sleep session". The watch will then use its built-in microphone to record your snoring activity.
To check your Snore detection data the following morning, open the Samsung Health app on your phone and tap the Sleep tracker. Then, swipe to and tap the data under Snoring. The data will include timestamps that show the period(s) during sleep when you were snoring. You can also view this data on your watch by swiping left on the watch home screen until you see the Sleep tile, then tapping it and swiping up to see all of your data.
It is important to note that the Galaxy Watch 5 is not a substitute for a medical device or opinion.

The sleep coaching feature then builds a personalized four-week sleep coaching plan, providing useful tips and guidance for improving sleep habits. The watch will monitor your sleep data, such as your blood oxygen levels, sleep time, sleep score, sleep stage, and sleep consistency.

Blood oxygen levels
The Samsung Galaxy Watch 5 can measure your blood oxygen levels while you sleep. Blood oxygen saturation, or SpO2, indicates how efficiently your blood carries oxygen throughout your body, which in turn tells you whether you're breathing effectively. A typically healthy range is between 95% and 100%, but this can be affected by factors like exercise, elevation, temperature, and health conditions.
To enable blood oxygen tracking on your Galaxy Watch 5, first, make sure your watch is positioned correctly. According to Samsung, your watch should be positioned the width of two fingers above your ulna, the pointy bone on your wrist. A snug fit will improve blood oxygen monitoring accuracy. You should also ensure that your watch is on the top of your wrist, not the underside, and not pressing against the bone. If your hands and arms are cold, remove your watch and rub your wrist gently to warm up your skin before trying again.
Next, open the Samsung Health app on your watch. Swipe to and tap Settings, then tap the switch next to Blood Oxygen during sleep to turn it on. You can also enable Snore detection and Sleep coaching options.
After a night of sleep, you can view your blood oxygen data in the Samsung Health app. The app will provide your blood oxygen percentage, the minimum saturation percentage, and the total time blood oxygen saturation was under 90% during the night. This data can provide insights into your fitness and wellness, but it should not be used for diagnosis. If you notice concerning data or feel sluggish in the morning, you should seek advice from a healthcare professional.

Sleep score
The Samsung Galaxy Watch 5 offers advanced sleep tracking, including sleep coaching and snoring detection. The sleep score is an important part of the sleep tracking feature. The sleep score is a number between 1 and 100 that indicates how good your sleep was. The higher the sleep score, the better the sleep.
The sleep score is calculated based on five factors:
- Total sleep time: Sleeping too much or too little will negatively affect your sleep score. Samsung believes adults should get between 6 and 9 hours of sleep per night.
- Sleep cycles: A sleep cycle usually lasts around 90 minutes and includes non-REM and REM sleep. According to Samsung, adults should have between 3 to 7 cycles per night to achieve a high sleep score. Registering 0-3 sleep cycles will lower your score.
- Movements and awakenings: The watch records the percentage of sleep that is uninterrupted. A figure between 10% and 40% is ideal.
- Physical recovery: This is directly related to deep sleep, which is considered the physically restorative phase of sleep. A figure of 40% or above is considered excellent.
- Mental recovery: This is related to REM sleep, which is linked to memory, learning, and mental health. A 60% or above figure will contribute to a high sleep score, while a lower percentage will result in a lower score.
To view your sleep score, open the Samsung Health app on your Galaxy Watch 5. You can also view your sleep score on your connected phone by tapping the "Show on phone" button at the bottom of the screen.
