Xiaomi Mi Band 4 launch: full instruction from unpacking to synchronization

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular gadgets for tracking activity even years after its release. AMOLED-The screen, sleep monitoring and smartphone notifications are all appealing to both beginners and experienced users, but the first launch of the device may raise questions about how to properly charge the bracelet, connect it to the phone and adjust the basic settings?

In this article, we will take the Mi Band 4 launch process in steps, from unpacking the box to personalizing the screen, focusing on common errors (for example, the bracelet does not turn on after charging or does not sync with the application), and give recommendations for optimizing the gadget. If you just bought the Xiaomi Mi Band 4 or pulled it out after a long downtime, this guide will help to avoid common problems.

1. Unpacking and inspection of equipment

Before you first turn on, make sure that the box with Xiaomi Mi Band 4 contains all the necessary elements.

• 📦 Mi Band 4 fitness bracelet (with capsule installed)
• 🔋 Charging cable (specialized module with contacts)
• 📄 Short instructions in several languages (including Russian)
• 🔄 Band (usually black, but may vary depending on version)

If you don't have any of these items, you should contact the seller, and you should pay attention to the integrity of the package, because if the box is opened or damaged, it may indicate that it's not original, and you should also check the serial number on the back of the capsule, which should match the number on the box.

If you have bought a used bracelet, be sure to ask the previous owner if the reset was performed before the factory settings, otherwise you will have to do it yourself (the instructions are given in one of the following sections).

Charging the bracelet before first switching on

Xiaomi Mi Band 4 comes with a discharged battery, so before the first use it must be charged.

1. Remove the bracelet capsule from the strap by pressing the button from the back.
2. Connect the capsule to the charging cable: the contacts on the bracelet should fit tightly to the contacts on the charging.
3. Connect the cable to the power source (USB-Computer port, smartphone charger or power bank).

The bracelet will display a charging indicator, a battery icon with an animation of filling. It takes about 1.5-2 hours to fully charge (depending on the power source), and it is not recommended to use chargers with an output current greater than 1A to avoid overheating the battery.

⚠️ Warning: If the bracelet is not responding to charging (the screen remains black), try to clean the contacts with an alcohol napkin or soft cloth. Also check if any contact on the charging cable is bent - this is a common reason for not charging.

Once 100% charge is reached, the bracelet can be turned off, but experts recommend that the first charge be brought to full battery capacity to calibrate the power controller, which will help to avoid inaccurate charging readings in the future.

3. Enabling and basic bracelet setting

After charging, the Mi Band 4 can be turned on.

1. Put the capsule back in the strap (if you removed it for charging).
2. Touch the touch button under the bracelet screen. If the screen is not responding, press the button for 3-5 seconds.
3. The Mi logo will appear on the screen, after which the bracelet will go to the main menu.

By default, the bracelet will display the time, date and battery level, but for full use, you need to connect it to the smartphone through the official Mi Fitness app.

• 📱 Receive notifications of calls and messages
• 📊 Tracking activity and sleep statistics
• 🔄 Update the bracelet firmware
• 🎨 Change the dials and screen settings

If you already have Zepp (for newer Mi Band models), it won’t work for Mi Band 4. Use only Mi Fitness, which is available for Android and iOS.

💡

If the bracelet doesn’t turn on after charging, try resetting it to factory settings. To do this, press the touch button for 10-15 seconds until the vibration and the Mi logo appear.

4.Installation and configuration of the Mi Fitness application

2. Click Add Device and select the Bracelet → Mi Smart Band 4.
3. Allow the application to access notifications, contacts, and geolocation (necessary for the functions to function properly).
4. Follow the instructions on the screen to pair the bracelet over Bluetooth.

During synchronization, the bracelet can reboot, which is normal. Once successfully connected, the app will prompt you to update your firmware (if a new version is available). Always update your firmware as new versions fix bugs and add features (for example, support for additional dials).

5. Personalization of the bracelet: dials, notifications, functions

After successful synchronization, you can customize the Mi Band 4 to your needs. The main options are available in the Profile → Mi Smart Band 4 section of the Mi Fitness app:

However, remember that the Mi Band 4 has 5 ATM protection, which means waterproof up to 50 meters, but is not designed for hot baths or saunas.

Typical errors and their solution

Even after setting up the Xiaomi Mi Band 4 correctly, let’s look at the most common problems and ways to fix them:

🔋 Bracelet discharges quickly

If the battery goes down in 1-2 days instead of the promised 14-20, check:

• 📶 Synchronization frequency with the phone (in the application settings, reduce the interval to 1 time per hour).
• 🔄 Number of active notifications (disable unnecessary applications).
• 🌡️ Constant time display mode (if turned on, it consumes a lot of battery).

📵 The bracelet is off the phone.

The problem is often related to:

• 📱 Energy-saving phone settings (add Mi Fitness to exceptions).
• 🔄 Bluetooth device conflict (disable other gadgets, such as headphones).
• 📲 Outdated firmware bracelet (update through the application).

🕒 Time-image

If the bracelet shows the wrong time, sync it manually:

1. Open Mi Fitness and go to bracelet settings.
2. Choose to sync the time.
3. If the problem recurs, check the time zone on your phone.

⚠️ Note: If the bracelet has stopped responding to touch or the screen has become glitchy (artifacts, flicker), this may indicate damage to the plume inside the capsule. In this case, contact the service center - self-repair is usually impractical due to the fragility of the components.

7.Tips to extend the life of the bracelet

Xiaomi Mi Band 4, when handled carefully, will last 2-3 years or more. To maximize its life, follow these recommendations:

• 🚿 Avoid contact with aggressive substances (shower gels, creams, hairspray) that can damage the strap and screen covering.
• 🔥 Do not leave the bracelet in direct sunlight (especially on the dashboard of the car.
• 🔋 Charge the bracelet at a temperature of 10-35°C. Charging in the cold or heat reduces battery life.
• 🧼 Clean contacts and straps regularly with a soft cloth soaked in soapy solution. Use alcohol wipes (at least 70% alcohol) to disinfect).

If you are actively exercising, it is recommended to remove the bracelet during strength exercises (for example, pressing a barbell) to avoid mechanical damage to the screen.

Also, it is worth periodically (every 3-6 months) to update the firmware of the bracelet through the Mi Fitness app. New versions of the software optimize power consumption and add support for modern smartphones.

💡

Regular cleaning of contacts and firmware updates are two key factors that extend the life of the Mi Band 4 by 30-50% longer than the standard term.
