How to turn on Xiaomi Mi Band 4: the first on and setup

Modern wearables from Xiaomi have become the benchmark of accessibility and functionality, but beginners often have a stupor when they first contact a device. Activation of a tracker is not just a mechanical push of a button, but a whole preparation process that requires understanding the logic of the device. Many users mistakenly believe that the device will work immediately after being removed from the box, but this is not true.

To work properly, the Mi Band 4 requires a number of preparatory steps, including installing specialized software on a smartphone. Without pre-configuring through the application, the interface of the bracelet will remain in the manufacturer's language, and many functions will not be available. It is important to understand that a key element of the ecosystem is a bundle of "smartphone-tracker", controlled via Bluetooth protocol.

In this guide, we will take a detailed look at each step, from check-up to first successful pairing, learn how to avoid typical charging errors and why regional settings can play a crucial role. Careful follow-up to the steps of the instructions ensures that your gadget will last a long time and will delight in the accuracy of data.

Initial check of configuration and battery condition

Before you try to activate the device, you need to make sure that it is physically ready to work. Factory equipment Xiaomi Mi Band 4 usually includes the tracker with the capsule, silicone strap and charging cable. However, long-term storage in stock could lead to a deep discharge of lithium-polymer battery.

If the device has been on the shelf for several months, the indicators may not light up immediately after connecting to the network. This is normal for electronics of this class. In such cases, you need to leave the gadget on charge for at least 30-40 minutes, even if the screen remains black, only after that you can expect a reaction of the system.

⚠️ Warning: Do not use the powerful Quick Charge, Power Delivery units of modern smartphones to initially charge the bracelet. Currents greater than 1A can damage the capsule's power controller. Use a standard one. USB-computer port or power supply with a current of 500 mA.

Visually inspect the contact pads on the back of the capsule. They should be clean and dry. Having oxides or a protective film (which is sometimes forgotten to remove) will make charging impossible. Wash the contacts with dry soft cloth before mounting into the charger.

Installation and configuration of the Mi Fit application

The central element of managing your fitness tracker is the mobile app. For Android and iOS users, Mi Fit (renamed Zepp Life in some regions) remains the main tool, downloading the program exclusively from official stores: Google Play Market or Apple App Store to avoid the introduction of malicious code.

After installation, you need to register your Mi Account. This is a prerequisite without which data synchronization is impossible. When registering, it is important to specify the region correctly, since it depends on the server on which your health data will be downloaded. For users from CIS countries, it is often recommended to choose the region corresponding to the country of residence, or sometimes China, if the functionality in other regions is limited.

In the application settings, it is important to allow all the requested permissions immediately: access to geolocation, Bluetooth, notifications and background. Without permission to geolocate in Android smartphones, finding a device using Bluetooth often does not work due to the limitations of the operating system itself. Make sure that the right type of gadget is selected from the Profile → Adding Device menu.

First incorporation and interface process

The moment of turning on the Mi Band 4 often goes unnoticed, since there is no separate power button on the case. The device activates automatically when connected to a power source or when you first press the touch button for a long time (if the charge is sufficient).

The pairing is done exclusively through the app, not through the phone's Bluetooth settings. If you try to connect the bracelet through the smartphone's system menu, the connection will not establish or work correctly. The algorithm must be strictly consistent: open the app, press Add, select the Bracelet, then press and hold the touch button on the tracker until the vibration and the Bluetooth icon appear.

During the process, a request for firmware updates may appear on the smartphone screen, which is a critical step: don’t miss it, as the factory version of the software often contains errors that affect the stability of the sensors and the accuracy of the pedometer. Update can take from 5 to 15 minutes, while holding the phone next to the bracelet.

⚠️ Note: During the Firmware Update, it is strictly forbidden to turn off Bluetooth or take the smartphone away from the bracelet. Interrupting the process can lead to the "bricking" of the device, after which it will be possible to restore it only in the service center.

Interface setting and personalization

After successful pairing, you open up a world of personalization. Mi Band 4 differs from its predecessors in the presence of color. AMOLED-It's a free app that you can download and install in a single click, and it's not just a decoration, it's also a way to bring the data that you care about to the screen.

In the device settings menu in the application, you can change the system parameters:

• 📱 Interface language: choose Russian or another language that is convenient for you, so that the menu on the bracelet becomes clear.
• ⏰ Time format: set up a 12-hour or 24-hour display format.
• 🔔 Notifications: Select applications that have notifications duplicated on your wrist (WhatsApp, Telegram, calls).
• 💪 Activity goals: Set realistic steps you plan to take every day.

And you also need to look at the wrist lift function, which activates the screen when you turn your hand to look at the time, and you can adjust the sensitivity of this function to avoid false switching in your pocket or when you're moving your hands.

Diagnosis: if the bracelet is not turned on

It's not uncommon for a new device to show signs of life, and most often it's not marriage, it's the nuances of operation. If the screen is black and there's no vibration even after you've connected to the charger, check the position of the contacts. The capsule should fit tightly to the charger pins, sometimes you need to move it slightly left or right.

Another common reason is to stick the system, and in this case, reboot will help. There is no physical Reset button on the Mi Band 4, so you need to find the System item (the gear icon) in the brasto menu and choose Unlock or Reboot if the menu is available. If the screen does not respond, try charging the device for a long period (2-3 hours).

The table below shows the main indicators of the condition and their value:

Sensor calibration and measurement accuracy

For your pulse and step data to be accurate, you need a calibration period. In the early days, wear the wristband tightly but without swaying your wrist. The optimal position is two fingers above the wrist bone. This is where the pulse is felt most clearly, and the PPG optical sensor works more efficiently.

You can set your heart rate schedule to save battery life by setting a 10-minute or 30-minute interval, but athletes should choose a continuous monitoring mode during exercise, and you should also turn on the Monitoreo de sueño (sleep monitoring), which is automatically activated at night.

💡

For maximum pedometer accuracy, enter your height and weight in your application profile, and calorie counting and stride length algorithms are directly dependent on this anthropometric data.

Remember to sync your data regularly. Although the bracelet memory allows you to store training information for several days, regularly uploading to the Mi Cloud or the application server will help you build accurate progress graphs and analyze the dynamics of changes.
