Modern wearables have become an integral part of the lives of millions of users, and Xiaomi Mi Band 4 is a leader in this segment due to the optimal ratio of price and functionality. However, after taking the device out of the box, many beginners face an unexpected moment: the bracelet does not respond to touch and the screen remains black. It is not a marriage and not a discharged battery, but a feature of logistics and electronic storage that requires the right activation.
The first activation of a fitness tracker requires understanding the basic principles of its operation and the presence of a smartphone with an installed application. The launch process is simple, but ignoring the sequence of actions can lead to a false conclusion about the malfunction of the device. In this article, we will discuss in detail how to activate the gadget, conduct initial synchronization and avoid the typical mistakes that inexperienced users make when first familiarizing themselves with Mi Band products.
It's important to note right away that the Mi Band 4 doesn't have a physical power button, and it's all controlled through the touchpad and the power supply connection. It's the voltage application to the controller that triggers the device's operating system. Let's take a detailed look at each step so that your new tracker works correctly on the first try.
Reasons for the lack of reaction when extracted from the box
Many users mistakenly believe that the electronics should work immediately after unpacking, but manufacturers deliberately discharge the batteries to a minimum before sending them to warehouses. This is done to protect and preserve the life of the lithium polymer battery during long-term storage. If you take out the Xiaomi Mi Band 4 and it does not turn on, this is absolutely normal situation, requiring initial charging.
The charge level can drop to a critical minimum, at which the indicators do not light up yet, and the screen does not respond to touch, in which case you just need to connect the device to the charger, do not panic or try to disassemble the case, as this will lead to loss of warranty and possible damage to the moisture protection.
Sometimes the problem is oxidation of contacts or contamination of the charging pad. Before connecting to the network, it is recommended to wipe the back of the capsule and contacts of the charger with a dry soft cloth, which will ensure reliable contact and stable current transfer.
⚠️ Warning: Do not use powerful fast-charging power supplies (Quick Charge, Power Delivery) to charge the bracelet, as this can damage the tracker's power controller. USB-computer port or adapter with current 1A.
After connecting to the power source, the battery should appear on the screen, indicating the beginning of the process of energy storage, and if the screen catches fire, then the device is healthy and ready for further manipulation.
The process of first charging the device
To activate the Xiaomi Mi Band 4, you need to remove the capsule from the strap and insert it into a special charger included in the kit. The charging design is designed so that the capsule is fixed in one correct position: contacts down. If you plugged in the device but the screen does not light up, try turning the capsule 180 degrees.
The charging process takes a little while, but for the first turn on, it takes 5-10 minutes for the system to start. During charging, the display can display a percentage of charge or animation of the battery. It is important to make sure that the contacts fit tightly together, otherwise the process can be interrupted.
Once the device shows signs of life, you can carefully remove the capsule from charging and insert it back into the strap. Now the activity tracker is ready to pair with the smartphone. It is not recommended to leave the device on charge for a long time after full charge, although modern controllers are able to cut off current.
⚠️ Attention: If after 15-20 When charging the screen does not light up, check the integrity of the cable and try another one. USB-In rare cases, the problem may be in the charging cable itself.
Once you've made sure the screen works, move on to the next step, which is installing the software, and without the application, you can't fully configure and use the bracelet's functions.
Installation and configuration of the Mi Fit application
The Xiaomi Mi Band 4 is managed using the official Mi Fit app (in some regions it may be called Zepp Life), downloaded from Google Play Market for Android or App Store for iOS. Make sure you download the app from official developer Anhui Huami Information Technology to avoid malware.
Once installed, you need to register for an account or log in to an existing one, which is a must, as all your health and activity data are synced to the cloud, and when you register, include real data, as it is the correctness of your calorie and step calculations.
Why is accuracy important when registering?
The app must provide all the permissions it requests: geolocation, Bluetooth, notifications, and background work, without which the bracelet will not be able to transmit data or display notifications of calls and messages on the screen.
The interface of the application may seem overloaded, but for the first turn on, we are only interested in the Profile tab and the device add button, and this is where the search and initial configuration of your gadget occurs.
Interconnection of the bracelet with a smartphone
The process of pairing Xiaomi Mi Band 4 with a smartphone is via Bluetooth. Open the Mi Fit app, go to Profile and click Add Device. Select from the list of "Mi Band 4" and follow the instructions on the screen.
When you search for a device, a confirmation code may appear on the wristband screen. If the code matches what's on your phone, press the confirmation button on the tracker (touch the touch area), which is necessary for security so that you don't connect to someone else's device.
☑️ Checklist of successful pairing
If the search is not working, make sure the bracelet is not connected to another phone.The fitness bracelet can only pair with one smartphone at a time.If it was previously tied to another device, it should be untied in the app on that phone.
Once the app is successfully connected, it will offer a firmware update, an important step, as the factory version of the software may contain errors or not support Russian, and the update will take a few minutes, during which time the phone must be next to the bracelet.
Setting up the language and basic parameters
One of the main tasks after turning on is to configure the interface language. By default, the Xiaomi Mi Band 4 can display menus in English or Chinese. To change this, in the Mi Fit app, go to the bracela settings and find "Language".
Select "Russian" or "English." Once you select the language on the tracker screen will change automatically. If Russian is not on the list, you need to check for firmware updates, as support for languages is added through them.
Also, at this point, you should set the dial, and there are a lot of options available in the theme store, from classic watches to sports indicators, and the choice of dial affects not only the aesthetics, but also the information content of the display.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Wrist lifting | Included. | The screen lights up when raising your hand. |
| Time to quench | 5-10 seconds | Savings in battery charge |
| Vibration. | Medium | Balance between visibility and comfort |
| Synchronization | Automatic. | Update in the annex |
Remember to set the time and date, although they are usually automatically pulled up from your smartphone, and checking these parameters is important for the correct operation of alarm clocks and reminders.
💡
Proper setting of the language and dial immediately after purchase will eliminate confusion in further use and make interaction with the device comfortable.
Solving Typical Startup Problems
Even if you follow all the instructions, you can have technical difficulties. If the Mi Band 4 doesn't turn on after charging, try rebooting it. To do this, plug the bracelet into charging, wait for the battery icon to appear, then turn it off and reconnect it.
A common problem is not notifying you of incoming calls or messages. Check in the Mi Fit app if the switches for the desired applications are on in the "Application Notifications" section. Also make sure the app has permission to work in the background, otherwise the Android system may "sleep it down."
If the bracelet is constantly losing connection to your phone, try uninstalling the device in your Bluetooth settings on your smartphone and pairing again, sometimes cleaning the Mi Fit app cache or reinstalling it helps.
⚠️ Warning: Do not try to "swipe" the bracelet with third-party utilities at the first sign of unstable operation. This can lead to a complete locking of the device ("brick"), which cannot be fixed at home.
In the case where neither method works and the device does not respond to charging for more than an hour, it may be a factory defect, in which case it is advisable to contact the point of sale to replace the product under warranty.
