How to start using Xiaomi Mi Band 4: a complete guide for beginners

Where to start: unpacking and first launch

You just got the lucky owner of the Xiaomi Mi Band 4, one of the most popular fitness bracelets on the market? Great choice! This compact gadget can track steps, pulse, sleep, display notifications from your smartphone and even control music. But before you dive into the world of activity tracking, you need to properly prepare the device for operation.

Start by unpacking. In the box, you'll find the bracelet with the strap itself, the charging cable (usually magnetic, without a USB-C/Micro-USB connector), and a brief instruction in several languages. Pay attention to the protective film, which is better removed immediately so that it doesn't interfere with the sensor. Also check the kit: sometimes manufacturers add spare straps or stickers for personalization.

Charge the bracelet to at least 50% before the first turn on. Despite the fact that the Mi Band 4 uses a capacious battery (up to 20 days of operation), the new gadget is often discharged after long storage in stock. Connect the magnetic cable to the bracelet, and it's supposed to stick to the contacts on the back of the case. USB-port.

Installation of the Mi Fit application and pairing with the phone

Without a smartphone, Xiaomi Mi Band 4 turns into a regular watch with a pedometer. To unlock the full potential of the bracelet, download the official Mi Fit app (available for Android 5.0+ and iOS 10.0+). Find it in Google Play or the App Store - it is important to download the original version, not clones.

After installation:

• 📱 Launch Mi Fit and register (via Google, Facebook or phone number).
• 🔍 Click Add Device and select Mi Smart Band 4 from the list.
• 📶 Allow the application to access notifications, geolocation and contacts (this is necessary for the correct function).
• 🔗 Turn on Bluetooth on your phone and wait until the bracelet appears in the list of available devices.

If the bracelet is not present, try:

⚠️ Warning: Make sure that the Mi Band 4 is at least 20% charged and within 1 meter of the phone. Also check if the bracelet is connected to another device, in which case it must first untie using the settings of the previous smartphone.

Set up the main parameters: time, notifications, profile

After successful pairing, the app will offer to update the firmware of the bracelet — agree, as new versions fix errors and add features. The update will take 5-10 minutes, do not turn off Bluetooth at this time.

Now let’s move on to the basic settings:

1. Time and Date: Sync automatically with your phone, but if the clock is going down, check the time zone in your smartphone settings.
2. Notifications: In Mi Fit → Device Profile → Notifications Choose which apps can send the alerts to the bracelet (calls, SMS, WhatsApp, Telegram, etc.).
3. User Profile: Specify your height, weight, age and gender for accurate calorie count and sleep analysis.
4. Activity goals: The default is 10,000 steps a day, but you can change the goal in the Goals section.

Important: If notifications don’t come to the bracelet, check the power saving settings on the phone – some models (such as Xiaomi or Huawei) block the background work of the Mi Fit. To fix this, add the app to the Protected list or turn off battery optimization for it.

Fitness functions: pedometer, pulse, training

The main advantage of the Mi Band 4 is activity tracking, and the bracelet automatically counts steps, distance and calories burned, but for accurate data you need to:

• 📊 Regularly sync data with Mi Fit (manually or automatically when connected to a phone).
• 🏋️ For training, choose the appropriate mode (Running, Bicycle, Swimming, etc.) - this improves the accuracy of measurements.

For pulse measurement:

1. Sit down and relax for 1-2 minutes.
2. On the bracelet, select the Pulse section (heart icon).
3. Do not move your hand during the measurement (usually 10 to 30 seconds).

The Mi Band 4 does not replace medical equipment, and pulse readings can vary by ±5-10 beats from professional blood pressure monitors, especially when driving.
