Does the Redmi Watch 4 support sleep monitoring?

The watch supports all-day sleep monitoring, all-day long sleep and sporadic nap monitoring. After turning on “Sleep High Precision Monitoring”, the distribution of sleep quality can be presented. Wearing the watch to sleep at night, the watch can automatically recognize it through the built-in sensor.
If you have interest in how to view sleep data, please refer to the following information:
1. Swipe left and right on the home page to the entrance of the sleep component to view last night’s sleep time, and tap to enter the APP to view more information;
2. Tap the [Sleep] icon in the Application list to open sleep monitoring, you can view the sleep data of the day;
3. After connecting the watch and cell phone to synchronize data, in the data section of the Mi Fitness APP, tap [Sleep] to view historical sleep data daily, weekly, monthly, and annually. You can also view the percentage of deep sleep, light sleep, rapid eye movement, lucid sleep, as well as the detailed sleep status of each time point.
Note:
1. There is a delay in generating the sleep report. Opening the sleep monitoring at the first time after waking up will result in no sleep report for the time being;
2. The watch only retains the detailed sleep data of the previous night. Please synchronize the data to Mi Fitness APP in time to avoid data loss.
