New wearables often face the question of how to activate the device right after unpacking. For the Xiaomi Mi Band 4, the initial launch procedure has its own characteristics that differ from the inclusion of a conventional electronic watch. Many users mistakenly believe that it is enough to just press a button, but in the fourth generation of Xiaomi bracelets, the physical button is completely missing.
The main reason the activity tracker doesn't respond to touch is because the battery is deep after long storage in a warehouse. Factory battery charging is often less than 10%, which is not enough to fully start the device's operating system. So the first step should always be to install the tracker on the charger and connect it to a 5 Volt power source.
Once connected to the network, the indicators on the screen may not light up instantly, which is a normal electronic reaction to sleep mode. You will need to wait 5 to 15 minutes before the manufacturer's logo appears on the display. Only after the logo appears can you assume that the switching process has been launched successfully, and move to pairing with a smartphone.
Preparation for the first launch and inspection of the completeness
Before you try to activate the gadget, you need to make sure that all the components of the kit are intact. The standard box includes the tracker itself (capsule), a silica strap and a special charging cable. Note that the cable has a unique design: one side of it ends. USB-connector, and the other is a connector with two contacts, which is inserted into the recess on the back of the capsule.
Carefully inspect the metal part of the capsule where the charging contacts are located, which should be free of oxides, dust or protective film, which is sometimes forgotten to remove in the factory. If the contacts are contaminated, wipe them with dry soft cloth, as the presence of fat or dirt can interfere with the transmission of current.
☑️ Pre-insertion check
It is also important to prepare a smartphone that will act as a control center.For proper operation of the Mi Band 4 requires a device running Android version 4.4 or iOS version 9.0 and higher. Make sure that the phone is on the Bluetooth module, as without it, initial synchronization is impossible.
The charging process as an on-off trigger
Since there is no physical power button, the trigger role is to connect to the power source. You need to remove the capsule from the strap, gently pressing the convex part on the back to release the tracker. Then insert the capsule into the charger so that the contacts match, and connect the USB to the computer port or the charger adapter.
If the device is completely discharged, the screen can remain black for the first few minutes of charging.This does not mean that the bracelet is faulty; the power controller simply accumulates the minimum required charge to start the screen. In some cases, the process of "reviving" can take up to 20 minutes, especially if the gadget has been idle for several months.
⚠️ Note: Do not use chargers with quick charge (Quick Charge) power higher 1Oh, because it could damage the power controller of the tracker. USB-port 5V/1And.
Once the Mi Band logo lights up on the screen or the battery image appears, the power-up process can be considered running, after which the device will automatically go to standby mode or prompt you to select an interface language if it is the first on after reset.
Connecting with your smartphone through the Mi Fit app
To fully work the tracker you need to install the official application. Mi Fit was used before, but now the current program is Zepp Life (formerly known as Mi Fit). Download the application from Google Play or the App Store, register a Xiaomi account and log in.
After authorization, go to the Profile tab and select Add Device. In the list of available gadgets, find Mi Band 4. The application will start scanning the space, and if the bracelet is charged and turned on, it will appear in the list of devices available for connection.
The bracelet screen and app will show confirmation codes, check them and click the confirmation button on the tracker's touch screen, and after successful pairing, the time synchronization and notification settings will occur.
Configuring the interface and basic functions
After switching on and pairing, the user enters the main menu of the device. the Mi Band 4 interface is built on the basis of swipes: horizontal flips change the screens of functions (pulse, steps, weather), and vertical ones open additional settings or history.
In the settings section, available through long-pressing or menus, you can change the brightness of the display, the time format (12 or 24 hours) and the distance measurement unit, and you can also adjust the wrist lift function, which automatically turns on the screen light when you move your hand.
| Function | Description | Impact on the battery |
|---|---|---|
| Pulse monitoring | Continuous measurement of heartbeat | High. |
| Notifications | Vibration in calls and messages | Average. |
| The screen is Always On | Permanent lighting (not supported) | N/D |
| Phone search | Sound on a smartphone on command | Low. |
It is recommended to set activity targets, such as the number of steps per day and the time to go to bed, to allow the tracker to give more accurate recommendations and vibrational reminders about the need to warm up.
Solving Turn on and Screen Problems
If after a long charge the screen does not catch fire, try to reboot the procedure. To do this, put the bracelet on the charge, wait for the vibration or logo to appear, and immediately remove it from the contacts. Repeat the cycle 3-4 times. Sometimes this helps to "swing" the power controller.
Another common problem is the system freezes when the screen is on but not responding to touch, in which case you need to put the tracker on the charger. The connection to the current often causes the system to restart automatically, resetting temporary software errors.
What to do if the tracker warms up while charging?
In case none of the methods helps, there is likely a hardware malfunction of the battery or the screen plume, such devices require replacement at the service center, since the capsule design does not involve self-repair of the user.
Reset to factory settings (Hard Reset)
If the device is switched on but not working properly, or you plan to sell the bracelet, a complete reset may be required.In the menu of the bracelet itself, find Settings (the gear icon), scroll through to the end and select Untie or Reset.
Confirm the action by pressing the touch button, the device will restart, delete all the accumulated data and return to the state in which it was in the factory, and then you will need to re-conduct the pairing procedure through the application.
⚠️ Warning: Once the reset is done, all workout and sleep data not synced to the smartphone will be permanently lost. Make sure the Zepp Life app is open and the data is updated before the reset.
💡
Resetting your settings through the bracelet menu is the only safe way to return the device to factory status without losing warranty.
