What You'll Learn
Setting up a sleep schedule
Once your watch is updated, you can set up a sleep schedule using Bedtime Mode. To do this, access the Settings on your watch, navigate to the Advanced section, and select Bedtime Mode. Here, you can customise your sleep schedule by setting your desired bedtime and wake-up time.
It is important to note that the watch's sleep tracking feature may not always accurately differentiate between periods of sleep and wakefulness, especially when you are in bed but still active, such as watching TV or reading. This is because the watch detects a lower resting heart rate and assumes you are asleep. Removing your sleep schedule in the settings may help address this issue.
Additionally, the Samsung Health app offers a "blood oxygen during sleep" feature, which some users have speculated may be a bug or an upcoming feature. This feature is intended to provide insights into your blood oxygen levels during sleep.
By following these steps, you can effectively set up and utilise the sleep schedule function on your Galaxy Watch Active 2, gaining valuable insights into your sleep patterns and working towards improving your sleep quality.

Viewing sleep metrics and stats
The Samsung Health app can be used to monitor your sleep with the Galaxy Watch Active 2. The app provides daily goals and coaching programs to help you form better sleep habits. It measures the duration of each sleep phase and your movements while you sleep, and then assigns you a sleep score, which can be compared to the scores of other users in the same age and gender groups.
To view your sleep metrics and stats, you can review them on your paired phone instead of your watch. You can see the duration of each sleep phase, such as how much of your sleep was deep, light, or REM. You can also see your sleep score and how it compares to others.
The Samsung Health app also includes a snoring detection feature that records and alerts you to any sounds you make while sleeping. This can be helpful if you want to identify any potential sleep issues related to snoring.
In addition to the Samsung Health app, you can also use third-party apps such as Sleep as Android to track your sleep. However, some users have reported that they had to manually tell the watch they were sleeping when using third-party apps.
It's important to note that automatic sleep tracking may not always be accurate. For example, if you are in bed but awake and watching TV or reading, the watch may detect a lower resting heart rate and assume you are asleep. To improve accuracy, you can try removing any sleep schedules you have set up using Bedtime mode.

Using the Samsung Health app
The Samsung Health app, available on the Galaxy Watch Active 2, offers a range of features to help you understand and improve your sleep patterns. Firstly, the app monitors your sleep patterns and tracks your sleep movements, providing insights into the different phases of sleep you experience, such as REM, light, and deep sleep. This data is then used to calculate a sleep score, which can be compared to that of other users in your age and gender group.
To enable sleep tracking on the Samsung Health app, ensure that your watch software is up to date. You can check for updates in the Play Store or Galaxy Store on your watch. Once updated, the watch should automatically track your sleep without the need to activate any additional settings. However, you can also set a sleep schedule using Bedtime Mode in the settings to further enhance sleep tracking accuracy.
The Samsung Health app also includes a snoring detection feature, which records and alerts you to any sounds you make while sleeping. Additionally, the app continuously measures your blood oxygenation levels during sleep, providing insights into your overall health. These features offer a more comprehensive understanding of your sleep quality and can help identify any potential sleep-related issues.
While the Samsung Health app provides valuable information, it is important to note that it may not always accurately distinguish between periods of sleep and wakefulness, especially when you are physically inactive but still awake. This can result in discrepancies between your actual sleep duration and the watch's recorded sleep data. Therefore, it is recommended to review and, if necessary, manually adjust your sleep records to ensure accuracy.
Overall, the Samsung Health app on the Galaxy Watch Active 2 offers a convenient way to monitor and gain insights into your sleep patterns. By utilising the app's features and making any necessary adjustments, you can improve the accuracy of sleep tracking and work towards achieving better sleep habits.

Charging the watch
Charging the Samsung Galaxy Watch Active2 is simple, but there are a few things to keep in mind. Firstly, it is recommended to use a Samsung-approved wireless charging pad, as other wireless charging pads may not work properly with the watch. When using a Samsung-approved wireless charging pad, follow these steps:
- Connect the wireless charger to power and plug it into an electric socket.
- Place the watch on the wireless charging pad, aligning the centre of the watch's back with the centre of the charging pad.
- After the watch is fully charged, disconnect it from the wireless charging pad.
- First, disconnect the wireless charger from the power source before unplugging it from the electric socket.
You can also charge your Galaxy Watch Active2 using the Wireless PowerShare feature. This allows you to charge the watch with the battery of another device, such as a smartphone, that functions as a wireless charging pad. Here are the steps to charge your watch using Wireless PowerShare:
- Place the centre of the watch's back on the device that functions as a wireless charging pad.
- After the watch is fully charged, disconnect it from the device.
It is important to note that the Wireless PowerShare feature may not work properly with certain cover types on the device functioning as the wireless charging pad. It is recommended to remove any cover from that device before using this feature. Additionally, the charging speed may be affected by the type of charger used for the device functioning as the wireless charging pad, and the surrounding environment.
While charging the watch, you can tap the screen to check the charging status. To conserve battery life, you can activate Power Saving Mode, which displays colours on the screen as grey tones, deactivates the Wi-Fi network, and limits the CPU performance.

Comparing sleep scores
The Samsung Health app allows you to compare your sleep score with other users in the same age and gender groups. This can be accessed via the Galaxy Watch Active2, Galaxy Watch3, and Galaxy Watch4 series.
The sleep score is dependent on the duration of each sleep phase, with deep sleep being a key factor. Some users have reported that their watch often records a shorter duration of deep sleep than they expect, which impacts their overall sleep score.
The watch also measures blood oxygenation levels during sleep, but this feature is only available on the Galaxy Watch4 series. The snoring detection feature is another tool that can be used to gain insight into your sleep patterns and improve your sleep score.
While the sleep tracking feature on the Galaxy Watch Active2 provides valuable insights, some users have noted that it does not always accurately detect when they are asleep or awake. For example, if you are in bed reading or watching TV, the watch may register this time as sleep due to a lower resting heart rate. Removing the sleep schedule in the settings may help improve the accuracy of sleep tracking.
