Xiaomi’s modern wearable gadgets are designed to save battery life during storage in warehouses and stores, which is why they come to the buyer in a so-called “sleep” mode, from which they must be removed by force.
In this article, we will discuss in detail all the nuances of primary activation, setting up the region for work.

Initial preparation and battery charge check
Before you try to activate the bracelet, you need to make sure that there is enough energy in its battery. Factory charge is usually about 50-60%, but long-term storage on the store shelf could significantly reduce this figure. If the battery indicator on the screen does not light up when you connect to the charger, it does not always mean breakage.
The Mi Band 4 uses a special dock connector to be removed from the main body of the tracker. The capsule should be inserted into the USB connector in a specific way, controlling the position of the contacts. Usually, on the back of the capsule there is a marking indicating which side to connect the device to charge.
⚠️ Note: If the screen is black after 10-15 Lithium polymer batteries at deep discharge take time to "swing" before the screen gives a sign of life.
The process of restoring power can take anywhere from 30 minutes to several hours depending on the degree of discharge.

Use USB 2.0 ports on your computer or old smartphone power supplies (5V 1A) to charge, as modern fast charging can incorrectly detect a low-power device.
Installation and configuration of the Mi Fit application
The main control tool for Xiaomi Mi Band 4 is the Mi Fit app (known in some regions as Zepp Life). Without this software, the bracelet is just a screen with time, since all settings, dials and data synchronization occur through a smartphone.
Once installed, you need to register an account or log in to an existing one using email, phone number or social network. The account region is key, especially if you plan to use NFC functions for payment. For users from Russia and CIS countries, it is recommended to choose the region "Russia" or "China", depending on the version of the device's firmware.
In the app settings, it is important to allow all requested permissions, including access to geolocation, Bluetooth and notifications. Without these permissions, background sync will not work, and you will not be able to receive notifications about calls or messages on your wrist.
The interface is intuitive, but you should look at the Profile tab where new devices are added. This is where your Mi Band 4 is searched and paired. Make sure your phone is Bluetooth enabled and you start looking for new devices before you start the procedure.

Features of activation NFC-module
The Mi Band 4 NFC version differs from the usual presence of a contactless payment chip and more advanced smart home interaction features. However, for the NFC to work, it is not enough to just turn on the bracelet. You need to properly configure the region and tie the payment system, if it is supported in your country.
In most cases, NFC requires switching the region in the Mi Fit app to China, because Mi Pay and transport cards are initially targeted at the Chinese market, and after a region change, the bracelet may require re-pairing and updating to a special version of the firmware.

Resolving Typical Problems During Startup
Even if all instructions are followed, users may encounter difficulties. One of the common problems is when the phone sees the bracelet, but the connection is constantly disrupted. This may be because the device has already been paired with another phone and has not been reset.
To solve this problem, you need to reset to the factory settings. On the bracelet itself, this is done through the settings menu (the gear icon or swipe to the end to the right), where you need to find the item "Unbind" or "Reset." If the menu is not available, you can use the "Add device" function in the application, which itself will suggest resetting the gadget.
Another common mistake is the wrong date and time. If the bracelet displays an incorrect time, check the time settings on your smartphone and make sure you automatically sync over the network. After re-pairing, the time should be updated.
