Iphone X Sleep Tracking: How Does It Work?

The iPhone X does not have a built-in feature to track sleep. However, there are several ways to track sleep using an iPhone, including the Sleep/Bedtime feature, which is available on the Health app. This feature allows users to set sleep goals and create a customised sleep schedule. Additionally, the iPhone can be paired with an Apple Watch to track sleep. The watch automatically measures and records the number of times the wearer breathes per minute, and this data can be viewed in the Health app on the iPhone.

Using the Apple Watch

To track your sleep using the Apple Watch, you need to have an iPhone with the latest version of iOS and an Apple Watch with the latest version of watchOS. Before going to bed, ensure that your Apple Watch is charged to at least 30% with Sleep Tracking enabled.

When setting up your iPhone, open the Health app and tap "Get Started" under "Set Up Sleep", then tap "Next". Set the number of hours you would like to sleep under "Sleep Goals". You can also set your "Bedtime and Wake Up" times and a "Sleep Focus" to reduce distractions on your iPhone and Apple Watch. This will simplify your Lock Screen and turn on Sleep Focus at your scheduled bedtime.

After setting up your iPhone, you can adjust your wind-down and sleep goal as needed on your iPhone or Apple Watch. Open the Health app, tap "Browse" at the bottom of the screen, then tap "Sleep". If you have Sleep saved to your Favourites list, you can access it from the Summary page in the Health app. Tap "Full Schedule & Options", then tap "Wind Down" or "Sleep Goal" under "Additional Details". Adjust your time, then tap the option again to save your changes.

Open the Sleep app and tap the sleep-alarm-icon in the upper left. Tap "Wind Down" or "Sleep Goal" under "Options", then tap the Plus and Minus buttons to adjust your time. Tap the left arrow in the upper left to go back and save your changes.

To receive sleep data, ensure that "Track Sleep with Apple Watch" is enabled, and wear your Apple Watch for at least one hour each night. The Apple Watch can estimate the amount of sleep you get, the time spent in each sleep stage (REM, Core, and Deep), and when you wake up. It also helps track your sleeping respiratory rate.

Using the Health app

The Health app on the iPhone can help you set a sleep goal and create a customised sleep schedule. To get started, open the Health app on your iPhone and tap "Get Started" under "Set Up Sleep", then tap "Next".

Sleep Goals

Set the number of hours you would like to spend asleep.

Bedtime and Wake Up Times

Set when you would like to go to bed and wake up.

Sleep Focus

To reduce distractions, you can simplify your Lock Screen and turn on Sleep Focus at your scheduled bedtime. You can also give certain people or apps permission to notify you. You can also schedule a wind-down period to begin from 15 minutes to 3 hours before your bedtime, and your Sleep Focus will begin at the start of your wind-down time.

To view your sleep history, open the Health app on your iPhone or iPad. If you're on your iPhone, tap "Browse" at the bottom of the screen. If you're on your iPad, tap the sidebar to open it. Tap "Sleep". If you have Sleep saved as a favourite, you can access it from the Summary page in the Health app. The bar graph is set to "D" for daily by default. Tap "W" at the top of the chart to view your sleep history for the past week, "M" for the past month, or "6M" for the past six months. Tap "Show More Sleep Data" and select a category to review additional sleep details.

Manually adding sleep data

To manually add sleep data on your iPhone, you will need to use the Health app. First, open the Health app on your iPhone. Then, tap 'Browse' at the bottom of the screen and tap 'Sleep'.

If you have Sleep saved to your Favourites list, you can access it from the Summary page in the Health app. From here, you can view your sleep history. The bar graph is set to 'D' for daily by default. Tap 'W' at the top of the chart to view your sleep history for the past week, 'M' for the past month, or '6M' for the past 6 months.

To manually add sleep data, tap 'Add Data' in the top-right corner of the screen. To get cumulative sleep data, tap 'Show More Sleep Data'. You can also use Siri on supported models to manually add sleep data. For example, you can ask, "How much did I sleep last night?"

Siri voice commands

To track your sleep on your iPhone, you need to have the latest version of iOS and an Apple Watch with the latest version of watchOS. You can then use the Health app on your iPhone to set up sleep tracking.

You can also use Siri voice commands to track your sleep. Here are some examples:

• "Hey Siri, start Sleep Cycle." This command will initiate sleep tracking using the Sleep Cycle app, which is now integrated with Siri.
• "Hey Siri, how much did I sleep last night?" Siri can provide you with details about your sleep history, such as the number of hours you slept.
• You can also use Siri to set up sleep-related tasks, such as setting a sleep goal, creating a customized sleep schedule, or turning on Sleep Focus to reduce distractions before bedtime.

It's important to note that these Siri voice commands for sleep tracking may not be available in all languages or regions. Additionally, some features, like the iPhone Action Button for sleep tracking, are exclusive to certain iPhone models, such as the iPhone 15 Pro and newer.

Third-party sleep tracking apps

The iPhone X itself does not have a way to track your sleep. However, there are third-party sleep tracking apps that can be used in conjunction with the iPhone X to monitor sleep. These apps usually require that you wear something, like a fitness tracker or smartwatch, that senses your movements. However, there are also apps that don't require you to wear anything, but these tend to only work if you sleep alone. The data from these apps can be synced to your iPhone X, allowing you to view your sleep history and patterns.

It is important to note that the accuracy of sleep tracking depends on the device being used. The most accurate sleep trackers are considered to be EEG devices that measure brainwaves. However, other devices, like the Apple Watch, can also provide sleep tracking capabilities. When used with the iPhone, the Apple Watch can estimate the amount of sleep, the time spent in each sleep stage (REM, Core, and Deep), and the respiratory rate during sleep.

To use the Apple Watch for sleep tracking, ensure that it is paired with your iPhone X and that the Track Sleep feature is enabled. Additionally, make sure your Apple Watch is charged to at least 30% before bed and worn for at least one hour each night.

There are also other third-party sleep tracking apps available for iPhone users, such as those mentioned in the iOS community forums. These apps may offer different features and capabilities for tracking sleep, like the "In Bed" tracking behavior that was removed in iOS 18. By exploring these third-party options, users can find alternatives to the built-in sleep tracking features of the iPhone and Apple Watch.
