Setting up your sleep on Xiaomi Mi Band 4: from tracking to smart alarm clocks

The Xiaomi Mi Band 4 fitness tracker remains one of the most popular sleep trackers due to sensor accuracy and ease of use. However, many users are facing problems: the wristband does not record sleep phases, the alarm clock does not work or the data in the Mi Fit app is not displayed correctly. In this article, we will discuss all the stages of settings, from basic parameters to hidden functions that will help make sleep tracking as effective as possible.

The Mi Band 4 sleep configuration includes not only tracking activation, but also sensor calibration, sensitivity adjustment, app synchronization, and even creating individualized profiles for different types of sleep (e.g. daytime and nighttime).

It's important to understand that the quality of sleep tracking depends not only on the bracelet settings, but also on the firmware version, battery status, and even how you wear the device. For example, if the bracelet sits too loose, sensors can detect false movements, which distorts the data on deep sleep. In this manual, we will take into account all the nuances to make your Mi Band 4 work as a professional sleeprologist.

1. Preparation of the bracelet for sleep tracking: checking firmware and sensors

Before you set up sleep tracking, make sure your Xiaomi Mi Band 4 is ready for this task. Start by checking the firmware version - outdated software can cause sensor malfunctions.

1. Open the Mi Fit app on your smartphone.
2. Go to the Profile section → Xiaomi Mi Band 4 → Firmware update.
3. If a new version is available, upgrade the bracelet (make sure the battery is at least 50%).

Pay special attention to the heart rate sensor, which is responsible for determining the phases of sleep. If the sensor is dirty or not tightly attached to the skin, the data will be inaccurate. Wipe the bottom of the bracelet with an alcohol wipe and make sure that the strap is fastened tightly, but does not squeeze the arm (optimal position is 2-3 fingers above the wrist).

Also check the automatic sleep recognition settings:

• 🔄 Enable automatic tracking in Mi Fit → Xiaomi Mi Band 4 → Son → Auto-tracking.
• ⏰ Set a bedtime (for example, 22:00 to 8:00).
• 📊 Activate the option "Detailed sleep analysis" to break down into phases (light, deep, REM).

• ☀️ Turn on manual mode for daytime naps or if you go to bed outside your usual schedule.

To enable manual mode, swipe down on the bracelet screen and select the icon 🌙. To exit the sleep mode, press the bracelet screen and hold the button 1-2 seconds.

One of the most useful features of the Mi Band 4 is a smart alarm clock that wakes you up in light sleep to make your waking as comfortable as possible.

1. Open Mi Fit and go to Xiaomi Mi Band 4 → Alarm clocks.
2. Press "Add alarm" and set a time (for example, 7:00).
3. Activate the Smart Alarm option and select the interval (30 minutes recommended).
4. Set the days of the week and save the settings.

Now the bracelet will analyze your sleep and wake you up at the optimal time within a given interval, for example, if you set your alarm at 7:00 at 30 minutes intervals, the bracelet can work at any time from 6:30 to 7:00, choosing the moment of light sleep.

Important nuances:

• ⚡ Smart alarm clock only works when you automatically track your sleep.
