What You'll Learn
The Galaxy Watch 4 offers advanced sleep tracking
Sleep tracking on the Galaxy Watch 4 is designed to help users manage their overall sleep quality. The watch offers a full picture of your rest quality with a close look at your sleep patterns throughout the night. This includes light, deep, and active sleep zones, which are visible by default. To access REM sleep data, you can change the settings on your watch. REM sleep tracking uses heart rate variability (HRV) to help define this period of sleep, and having continuous heart rate monitoring will likely give you a better idea of how much REM sleep you're getting. However, setting heart rate monitoring to “frequent” will reduce battery usage overnight, which may be preferable despite a potential loss in accuracy.
The Galaxy Watch 4's automatic bedtime mode is designed to help with sleep tracking. However, some users have reported issues with sleep tracking, including the watch not recording the first few hours of sleep and not differentiating between light and deep sleep. These issues may be addressed in future software updates.
The watch's battery life is also important to consider when using sleep tracking. The larger Galaxy Watch 4 models offer longer battery life, with the 40mm Classic model lasting around 24 hours on a single charge with one night of sleep tracking. The bigger-sized watches have a 361mAh battery, while the smaller models have 247mAh batteries. Samsung claims that each watch should last around 40 hours on a single charge, but some users have reported inconsistencies with this, emphasizing the impact of always-on display and other features on battery life.

It can track REM sleep without continuous heart rate monitoring
The Samsung Galaxy Watch 4 offers advanced sleep tracking, providing valuable insights into your sleep patterns to help you improve your sleep quality. It can track your sleep patterns, snores, and blood oxygen levels. It also has an automatic bedtime mode.
However, some users have reported issues with the sleep tracking feature, including inconsistencies and inaccuracies in the data. For example, the watch may not record the first few hours of sleep, or it may categorise most of the night's sleep as light sleep, with little deep sleep or REM sleep recorded.
Despite these issues, the Galaxy Watch 4 can track REM sleep without continuous heart rate monitoring, thanks to a software update. This update introduced a toggle for enabling or disabling REM sleep recording. While continuous heart rate monitoring may provide a better understanding of REM sleep, as heart rate tends to be faster during this period, it can reduce battery life. By setting heart rate monitoring to "frequent" (measuring heart rate every ten minutes), you can achieve a balance between battery life and the accuracy of REM sleep tracking.
To access the REM sleep recording toggle, open the sleep tracking widget on the watch, tap the three-dot button, and then enter the Settings. By default, REM sleep tracking will be enabled once the update is installed, but you can disable it using the toggle if you prefer.

It can detect snoring and factor it into sleep tracking
The Samsung Galaxy Watch 4 offers advanced sleep tracking, providing valuable insights into your sleep patterns to help you improve your sleep quality. The watch's recent software update has made sleep tracking more intuitive, especially when it comes to tracking REM sleep. While previous versions of the watch required continuous heart rate monitoring to track REM sleep, this is no longer the case. Now, users can toggle REM sleep tracking on or off as desired.
One of the standout features of the Galaxy Watch 4's sleep tracking capabilities is its ability to detect snoring. The watch can detect the sound of your snores, which is then factored into your device's sleep tracking data. This, combined with the watch's ability to measure your blood oxygen saturation levels while you sleep, provides a comprehensive view of your sleep patterns. By understanding your sleep patterns better, you can make informed decisions to improve your rest.
It's important to note that some users have reported issues with the accuracy and consistency of sleep tracking on the Galaxy Watch 4. There have been instances where the watch fails to record the first few hours of sleep or does not track sleep after waking up briefly during the night. These inconsistencies can impact the overall effectiveness of the sleep tracking feature.
Despite these reported issues, the Galaxy Watch 4 still offers a wealth of features for those seeking to improve their sleep quality. The snoring detection and blood oxygen tracking capabilities provide unique insights that can help users better understand their sleep patterns and make necessary adjustments. With its advanced sleep tracking, the Galaxy Watch 4 continues to be a competitive option in the smartwatch market.

It can measure blood oxygen saturation levels during sleep
The Samsung Galaxy Watch 4 offers advanced sleep tracking. It provides valuable insight into your sleep patterns to help you improve your sleep quality. The watch can track your sleep patterns, snores, and blood oxygen levels.
The Galaxy Watch 4 can measure blood oxygen saturation levels during sleep. This feature is known as SpO2 measurement. It can be used in combination with advanced Sleep Scores to help you understand your sleep patterns and improve your rest. This is an on-demand feature, meaning that you can choose when to measure your blood oxygen saturation levels.
The watch also has an automatic Bedtime mode, which activates when you go to sleep. This mode includes features such as non-tracking of Sleep Blood Oxygen and the ability to disable the always-on watch face to conserve battery life. However, some users have reported issues with the automatic Bedtime mode, such as the watch not counting additional sleep after getting up in the middle of the night.
In addition to sleep tracking, the Galaxy Watch 4 also tracks other basic health stats such as steps, daily calorie burn, active calories, distance, total active time, blood oxygen levels, resting and active heart rate, and stress. These activity stats are tracked through Samsung Health and can be viewed on the Samsung Health app.

The watch's battery life impacts its sleep tracking capabilities
The Galaxy Watch 4 offers advanced sleep tracking, providing valuable insights into your sleep patterns to help improve sleep quality. It can track your sleep patterns, snores, and blood oxygen levels. However, the watch's battery life can impact its sleep tracking capabilities.
The Galaxy Watch 4 has two size options, with the larger model featuring a 361 mAh battery and the smaller model featuring a 247 mAh battery. Samsung claims that each watch should last around 40 hours on a single charge. However, some users have reported that the watch only lasts for 1.5 days with the always-on display turned on and various features enabled, including heart rate and stress recording, location services, and one night of sleep tracking.
The smaller 40mm Galaxy Watch 4 Classic has a shorter battery life, lasting around 24 hours on a single charge with one night of sleep tracking. This variation in battery life between the two models may be due to the larger model having a higher-capacity battery.
To improve battery life and ensure sufficient power for sleep tracking, users can adjust settings such as turning off the always-on display, disabling certain features, and optimising screen brightness. Additionally, charging the watch for 30 minutes can provide about 10 hours of usage, but a full charge takes nearly two hours.
The watch's battery life can impact its sleep tracking capabilities, as a fully charged battery is required for accurate and uninterrupted sleep tracking throughout the night. Users should also be aware that certain settings, such as continuous heart rate monitoring, can provide more detailed sleep data but may consume more battery power. Therefore, users may need to find a balance between maximising battery life and obtaining the desired level of sleep tracking detail.
