● If you enable HUAWEI TruSleep
TM
, your heart rate will not display by default at
nighttime. To check your nighttime heart rate, enable Continuous heart rate
monitoring.
● Real-time mode increases the power consumed by your band, whereas Smart mode
adjusts the interval for heart rate measurements, based on the intensity of the activity,
to help preserve power.
● Your band uses invisible light to monitor your heart rate, and will switch between visible
light and invisible light to measure your heart rate, based on your sleep status.
● The band is capable of measuring heart rate values from 30 bpm to 240 bpm.
Resting heart rate measurement
Resting heart rate, is a general indicator of cardiac health, and refers to a heart
rate measured in a quiet, static, non-sleeping state.
To obtain your resting heart rate automatically, enable Continuous heart rate
monitoring in the Huawei Health app.
● If you disable Continuous heart rate monitoring after checking your resting heart rate,
the resting heart rate displayed in the Huawei Health app will remain the same.
● The best time to measure your resting heart rate is right waking up in the morning. The
device is unable to detect the exact optimal time to check your resting heart rate.
Therefore it may not be displayed at all times in the app, and differ slightly from the
actual value.
4.2 Sleep tracking
Your band collects sleep data and identifies your sleep status when you wear it
while sleeping. It can automatically detect when you fall asleep and wake up and
whether you are in a light or deep sleep. You can sync and view your sleep data in
detail in the Huawei Health app.
You can enable HUAWEI TruSleep
TM
in the Huawei Health app.
The band adopts HUAWEI TruSleep
TM
sleep tracking technology to accurately
detect whether you are in a deep sleep, light sleep, REM sleep (rapid eye
movement), or awake, and provide you with sleep quality assessments and
suggestions for improving the quality of your sleep.
Enabling TruSleep may slightly reduce your band's battery life.
4.3 Activity reminder
When Activity reminder is enabled, your band will monitor your activity to make
sure you don't sit still for long periods of time (set to 1 hour by default). If it
detects that you have been still for longer than the set period of time, the band
will vibrate and the screen will light up to remind you to take a break and walk
around.
