What You'll Learn
Huawei TruSleep technology
To view your sleep data, access the Huawei Health app home screen, and touch the Sleep card. Here, you can see detailed sleep data, including your sleep score, staging chart, and sleep details. You can also access historical sleep data records by navigating to the All data section on the Sleep screen.
To monitor your sleep, ensure you wear your Huawei device properly while sleeping. It will then automatically record your sleep data, including sleep duration and sleep stages. You can also use the 'Go to sleep' feature, where you place your phone within 50 cm of your pillow, and it will monitor and record your sleep data.
The Huawei sleep tracker also offers customisable sleep settings. You can enable Auto or Scheduled sleep modes. Auto is enabled by default, and the device will automatically enter and exit Sleep mode based on your sleep status. In Sleep mode, the device won't ring or vibrate for notifications or calls, except for alarms. The Raise to wake feature is also disabled in Sleep mode.

Keep in mind that if you disable TruSleep manually, you won't be able to access sleep data and analysis.
Sleep Tracking
Huawei's sleep tracking technology, TruSleep, uses PPG signals from heart rate detection and the Cardiopulmonary Coupling (CPC) algorithm to track sleep. It identifies motion features, classifies motion levels, and incorporates heart rate fluctuations to determine when you fall asleep and wake up. This technology focuses on five key sleep issues: difficulty falling asleep, frequent interruptions, insufficient sleep, irregular sleep schedule, and poor sleep quality.
Sleep Data
To view your sleep data, enter the device app list, select Sleep, and swipe up to access the More screen. Here, you can view your sleep health information, sleep duration, and sleep stages (deep sleep, light sleep, REM sleep). You can also access historical data records and delete them if needed. Additionally, you can view your Sleep score, staging chart, and sleep details on your wearable device, provided it has the latest software updates.

Understanding sleep tracking principles
Huawei's sleep tracking technology, TruSleep, uses PPG signals from the device's heart rate detection technology and the Cardiopulmonary Coupling (CPC) algorithm to monitor sleep. CPC calculates sleep stages and respiratory quality based on continuous single-lead ECG signals. There is a close correlation between ECG and breathing, which is enhanced when you are in deep sleep and can vary depending on whether you are awake, sleeping lightly, or suffering from a health ailment.
The ACC and PPG data is used by TruSleep to identify motion features, classify motion levels, and incorporate heart rate fluctuations to track sleep data such as sleep time, wake-up time, and sleep structure. The sleep tracking period is from 20:00 of the current day to 20:00 of the next day. Any sleep generated from 20:00 to 00:00 of the current day is recorded as the next day's sleep.
TruSleep 3.0 monitors sleep data such as fall-asleep or wake-up status, sleep duration, and maps sleep and body movements, heart rate, and heart rate variability (HRV) via a multi-modal fusion algorithm model to enhance sleep tracking accuracy. It focuses on five major sleep issues: difficulty falling asleep, frequent interruptions during sleep, insufficient sleep, irregular sleep schedule, and poor sleep quality.
To ensure accurate sleep tracking, the device should be worn correctly, with the screen facing upward and a snug fit on the wrist. It should be worn at least one-finger width above the wrist, and the rear cover should be clean, dry, and free of foreign objects. Signals from moving transports, such as airplanes, high-speed railways, and cars, may interfere with the device's sleep status identification, resulting in inaccurate sleep data.
