The first acquaintance with the fitness bracelet Xiaomi Mi Band 4 often raises questions among beginners, especially if the device was given as a gift or was bought as a backup. Many users mistakenly believe that it is enough to activate the gadget just to put it on the wrist, but this is not the case. Modern wearable devices require preliminary preparation and pairing with a smartphone for full operation.
The activation process is not complicated, but requires attention to detail, as the bracelet comes from the factory in deep sleep mode to save energy. Full battery charge before the first turn on is a prerequisite, ignoring which can lead to a false conclusion about the malfunction of the device. In this article, we will discuss in detail all the steps from extraction from the box to the first notification on the screen.
Component check and visual inspection
Before you try to run the Mi Band 4, you need to make sure that the components are intact. Inside the proprietary box, you will find the tracker itself, the interchangeable strap and the charger. The capsule is the bracelet computer itself, which is extracted from the silicone belt by light pressure on a special notch on the back.
Carefully inspect the contact areas at the back of the capsule, which should be clean, without oxides or protective film, which sometimes remains after production, if the contacts are visible film, it must be carefully removed, otherwise charging will not start and the device will not turn on.
Also check the status. USB-Xiaomi's fourth model uses a specific dock that requires tight contact attachments. Any contamination can be an obstacle to the battery supply.
☑️ Pre-launch checks
Primary charge of the device
As mentioned earlier, the factory charge in the battery is often minimal or nonexistent. Connect the capsule to the charger and then to the computer power supply or network adapter. It is important to use a source with a current of no more than 1 Amp, as powerful charges from smartphones can damage the tracker's power controller.
⚠️ Warning: If the screen doesn't light up immediately after connecting to the network, don't panic.The bracelet may take 5 to 15 minutes to store the minimum energy level before it can activate the display.
When charging, the zipper icon and the current percentage of charge should appear on the screen. If there is no indication, try to wipe the contacts with a dry soft cloth or a blower. Sometimes the oxide film on the contacts prevents the current from passing.
Leave the device to charge until it reaches 80-100%, and although the bracelet can turn on at 20%, it is better to have a maximum power reserve to correctly calibrate the battery and install updates, this will eliminate the risk of turning off at a critical point of setting.
💡
Use only the original charger or quality analogues to charge the Mi Band 4, as cheap Chinese power supplies often give power surges that are dangerous for electronics.
Installation and configuration of the Mi Fit application
Independently, without a smartphone, the Mi Band 4 functions in a limited mode, displaying only time and steps. To fully work, you need to install an official application. At the moment, the main application is Mi Fitness (formerly Zepp Life), which is available on Google Play and the App Store.

From now on, notifications and calls will be duplicated on the wrist. If the connection is interrupted, repeat the procedure by previously removing the device from the Bluetooth list in the phone settings.
⚠️ Note: Do not attempt to pair the bracelet directly through Bluetooth settings on Android or iOS. Connection must be made strictly through the Mi Fitness application interface, otherwise the functionality will be limited.
Configuring the interface and functions
After you turn on, you have to personalize. Mi Band 4 allows you to customize dials, widget display order and notification settings. To download new dials, you need to go to the store inside the application and choose your favorite design.
