Buying a new gadget is always accompanied by waiting, but sometimes the first step is not as obvious as you would like. Many users, unpacking the box with Xiaomi Mi Band 4, find that the device does not respond to touch and the screen remains black. This is normal, since the manufacturer deliberately discharges the battery before sending it to save its life during long storage.
Before you panic or carry a tracker to a service center, you need to perform a series of simple activation actions. Unlike smartphones, there is no physical on button, and all navigation is tied to touch control and interaction with the smartphone. The right initial activation is the foundation of a stable fitness bracelet in the future.
In this article, we will take a look at all the steps of starting a device, from connecting the charger to setting up notifications, how to distinguish factory transport from malfunction, and what steps to take if the standard algorithm does not work.
Primary activation and charging of the device
The first and most critical step is to put electric current on the battery, and because the Mi Band 4 could have been in storage for months, it could have gone into a deep discharge, and to get started, you'll need a special charging dock that comes with the kit, or any other battery that you want. USB-port with output current of at least 0.5A.
Remove the tracker from the silicone strap. This is done by exerting pressure on the rounded part of the capsule with your thumb, while pushing it out of the belt hole, and then the contacts on the end of the device will be available for connection. Put the capsule into the charger so that the metal pads coincide.
⚠️ Warning: Do not attempt to charge the device without removing it from the strap.Tight contact is possible only with direct connection of the contacts of the capsule and the charging dock, otherwise the charging process will not begin.
Connect. USB-The charging connector to the smartphone adapter or computer, the monitor screen should show a picture of the battery with a percentage of charge, if the screen catches fire, then the hardware is good, and the device has started to store energy. 15-20 minutes before attempting to switch on.
💡
For quick activation, use a powerful smartphone power supply (2A), but make sure that the capsule does not heat above 40 degrees during the process.
Installation and configuration of the Mi Fit application
The fitness bracelet will not function on its own, it needs a brain in the form of a smartphone, and the official Mi Fit app (known in some regions as Zepp Life) is used to manage all processes. Without it, you will not be able to synchronize time, adjust notifications, or even fully turn on the tracker.
Download the app from the official store: Google Play for Android or App Store for iOS. After installation, start the program and create a Xiaomi account if you do not already have one. This is a mandatory requirement for the ecosystem to work. When registering, provide the correct data, as it will be used to calculate health statistics.
In the app, go to the Profile tab and select Add Device. In the list of available gadgets, find Mi Band 4. The app will request permission to use Bluetooth and geolocation — agree, because without it, you can use it. GPS-Phone tags synchronization of data may not be possible.
☑️ Checking before synchronization
When the app starts searching, your device's name will appear on the smartphone screen. Click on it to pair. The tracker screen may show a vibration and a request for confirmation of pairing - tap the screen or button on the tracker if it is provided by the model, although in the fourth model, simply confirming on the phone is often enough.
The process of pairing via Bluetooth
Bluetooth Low Energy (BLE) technology used in the Mi Band 4 provides minimal power consumption, but it is during the pairing phase that there are often failures. If the phone does not see the bracelet, make sure that the old stored device with the same name is not hanging in the Bluetooth settings. If you have one, delete it.
The connection process is like this: the app scans the airwaves, finds the tracker signal, and sends a login request, at which point the confirmation code may appear on the Mi Band 4 screen, check the numbers on the phone and the bracelet, if they match, confirm the action.
Sometimes, Android or iOS security locks the connection, in which case, check the permission list for the Mi Fit app. It must be allowed access to Bluetooth, location, and background work. Without those permissions, the operating system will kill the connection process.
What to do if the code does not appear?
Once paired successfully, the tracker will automatically update the time and date, synced with the phone. The screen will light up to greet the owner and prompt you to select a dial. From that point on, the device is considered on and ready to go.
Diagnosis: Why the bracelet is not turned on
If the screen remains black for more than 30 minutes after being connected to charging, it is worth a diagnosis. The first cause is often oxidation of the contacts. Wipe the metal part of the capsule and the charging contacts with an alcohol napkin or eraser to remove the fat film or oxides.
The second reason is that the firmware is stuck, and in this case, the forced reboot helps, so you charge the device, wait for the vibrations, then turn it off. USB-cable from the network (without removing the capsule from the dock) and connect again through 5-10 Repeat the cycle. 3-4 once.
| Symptoms. | Possible cause | Method of decision |
|---|---|---|
| The screen's not on. | Deep discharge. | Leave on charging for 2 hours |
| Vibration's on, no screen. | Display malfunction | Replacement of the module is required |
| Can't see Bluetooth. | Mistake by | Reset to factory settings |
| Blinking red light | Battery error | Battery replacement |
⚠️ Warning: If the device gets too hot when connected to a charge (hot than just warm), immediately turn it off.This is a sign of a short circuit inside the battery, and further charging can be dangerous.
Configuring the interface and dials
After the Xiaomi Mi Band 4 is turned on, the user gets a colored version. AMOLED-This is the first device in the series to have a full-blown color display, which opens up a lot of customization options, and the basic dials are already built into the memory, but they can be changed through the app.
To install new dials, go to the Mi Fit app, select your bracelet, and find the Dials section, and there are dozens of options available, from classic analog to big-digit sports, some of which are paid, but free options are more than enough for personalization.
It's also important to adjust the brightness and activation time of the screen. By default, the screen goes out after 5 seconds, but this can be changed. Go to the bracelet settings in the app and find the screen settings. Here you can set the wrist lift time and brightness level (auto, low, medium, high).
Remember to activate the "Wrist Raise to Turn on the Screen" function, which allows you to see time with one hand movement without touching the sensor, but it is worth remembering that the constant operation of the accelerometer can slightly increase battery consumption.
Basic functions and health monitoring
The main purpose of the tracker is health monitoring. Mi Band 4 is equipped with an optical pulse sensor that works automatically. In the application, you can adjust the frequency of measurements: from once per minute to turn off the function to save energy.
The tracker also tracks sleep phases, analyzes movement and pulse, detecting deep and superficial sleep periods, and wakefulness moments, and synchronizes the data with the phone to form graphs that help adjust rest patterns.
Swimming mode is available for athletes, as the device has 5 ATM moisture protection. This means that you can swim in the pool with it at a depth of up to 50 meters. Before swimming in the settings, be sure to choose the appropriate activity mode so that the tracker blocks the screen from accidental touches with water.
💡
Automatic activity determination (walking, running) is enabled by default, but for accurate statistics it is better to manually start the desired training mode.
