The first inclusion of a new fitness tracker is always an exciting moment, especially when the device has such functionality as the Xiaomi Mi Band 4c. Many users mistakenly believe that it is enough to simply put a gadget on your wrist, but for full work you need to perform a number of preparatory actions. Without proper activation, the screen of the device will remain black, and the Bluetooth module will not be visible in the search for a smartphone.
The Mi Band 4c launch process is radically different from the powering of a regular electronic watch or smartphone. There is no physical power button, and the entire logic of the work is tied to the software and interaction with the mobile application. It is critical to understand that without pre-charging for 10-15 minutes, the tracker may not respond to pairing attempts due to deep battery discharge when stored in stock. In this material, we will discuss each step in detail so that you can avoid common errors.
Before you get into technical manipulation, make sure you have all the necessary components at hand. Xiaomi kits are usually minimalistic, but contain everything for the start. Check the availability of the charging cable and the tracker itself. Also make sure that your smartphone meets the minimum system requirements for working with the Mi Fitness or Zepp Life application.
Preparation for the first launch and inspection of the completeness
Start by taking a closer look at the device. The Xiaomi Mi Band 4c tracker comes in a protective film that must be carefully removed before use. Under the film, a layer that blocks the touch screen may hide, making the device appear to be out of service. Also check the contact areas on the back of the capsule: they must be clean and dry.
The next step is to provide an energy source. Even if the indicator is green when removed from the box, the charge level may not be sufficient to perform the initial setup and firmware update procedure. Connect the tracker to a USB power source of no more than 1A. Using powerful fast-charging units from modern smartphones can damage the power controller.
⚠️ Warning: Do not leave the device unattended on soft surfaces (sofa, bed) as this can overheat and damage the battery. Use only original or certified cable.
In parallel with the preparation (hardware) do the software.

If you bought a tracker that had been in storage for several months, the battery voltage could have dropped below the activation threshold.
The charging process is simple, but requires consistency. USB-The cable connector to the power adapter or the computer port. Only then attach the connector to the contacts on the back of the tracker. The magnets should click and the device will lock. If the screen does not immediately catch fire, do not panic, this is normal for deep-discharged batteries.
When you charge, pay attention to the screen. If you see a picture of a battery or a Xiaomi logo, the process goes. If the screen stays black for more than 30 minutes, try drying the contacts or using another one. USB-Sometimes the oxidation of the contacts prevents the current from passing.

Updating the firmware and calibrating the sensors
