Modern wearables have become an integral part of the lives of millions of users, and the Xiaomi Smart Band 4 remains one of the most popular fitness trackers on the market due to its price-performance ratio. Proper synchronization of the device with a mobile phone gives access to full functionality: from detailed training statistics to instant notifications from instant messengers. The initial setup process can seem confusing for beginners, but when following the sequence of actions, it takes only a few minutes.
In this article, we will take a look at all the stages of pairing, from hardware preparation to fine-tuning notification settings, how to avoid common Bluetooth connection errors, why third-party applications are sometimes necessary, and how to ensure that the smartphone-bracelet bundle works smoothly.
Before you go to the software part, make sure that your bracelet is at least 20-30% charged, as the initial synchronization process and possible firmware updates can require significant energy resources. Also check that your smartphone has enabled wireless and geolocation, as Android and iOS operating systems require access to GPS to correctly find low-power devices.
The first and most important step is to install the right software that will serve as a bridge between your phone and tracker. For Xiaomi devices, this app is called Mi Fit (or its updated version of Mi Fitness), which can be downloaded for free from official Google Play or App Stores. Using third-party utilities is not recommended, as they may not support all functionality or work unstable with a particular version of the bracelet firmware.
Once you install the app, you need to register for an account or log into your existing Mi Account. This is a requirement of the Xiaomi ecosystem to save your health statistics and settings in the cloud. When registering, enter data carefully, as it can take time to restore access to the account, and without it, data synchronization with the server will not be possible.
In the main menu of the application, go to the Profile section and click the Add Device button by selecting the Smart Band 4 model from the list. The application will request permission to use Bluetooth and geolocation - be sure to confirm these requests, otherwise the search for the tracker will not begin.The search screen will be active for 1-2 minutes, scanning the space around.
⚠️ Warning: Do not try to connect the bracelet directly through the standard Bluetooth menu of your phone settings. The pairing must occur strictly within the Mi Fit application, otherwise the device may “hang” in the status of the connected, but not transmit data.
When your tracker with its unique ID appears on your smartphone screen, click “Connect.” On the bracelet screen, you will see a request for confirmation of pairing — tap the touch button for confirmation. Once you connect successfully, the app will automatically check for firmware updates, which often contain important error corrections.
Sometimes users are faced with a situation where the application does not see the bracelet, although it is fully charged and on. Most often the problem is that the tracker was already paired with another phone or tablet, in which case you need to reset the bracelet to the factory or untie it in the application on the old device.
To reset the settings on the bracelet itself, swipe your finger across the screen to the right before the menu appears, find the gear icon (“More”) and select “Sever Communication” or “Reset” and then the device goes into standby mode. If the software reset does not help, you can put the bracelet on charging for 10-15 seconds, which sometimes forcibly restarts the Bluetooth module.
It’s also worth checking your smartphone’s energy saving settings. Android’s aggressive battery saving algorithms can block the background processes needed to find devices. Go to your phone’s settings, find the Mi Fit app, and let it run in the background as well as auto-start.
It is important to make sure that the phone is enabled geolocation (GPS).In modern versions of Android and iOS, finding Bluetooth Low Energy (BLE) devices is impossible without active location permission.This is a system limitation that cannot be circumvented, so just turn on the GPS before you start the search procedure.
Once successfully paired, you have a wide range of options for personalizing the tracker, and first of all, you should configure the notifications display so that only really important messages from WhatsApp, Telegram or SMS come to your wrist. Go to the profile of the device in the application, select Application Notifications and activate the desired sliders.
The Xiaomi Smart Band 4 supports image change, which makes the gadget more personal. You can choose from one of the standard options or download your own photo from the phone gallery, although it is worth remembering that complex images with small details can not be read well on a small screen.
Be sure to set activity goals such as step count, calories and sleep time, which will be used to form daily reports and motivational reminders. The app will analyze your current activity level and suggest realistic goals that can be adjusted manually as you improve your fitness.
☑️ Configuring after connection
Pay special attention to the setting "Raise the wrist to turn on the screen." This feature allows the screen to light up when raising the hand, which is very convenient. However, it can consume additional battery power, so if autonomy is a priority for you, this feature can be turned off or adjusted sensitivity.
For a deeper integration of the tracker with Android, there are advanced tools like Notify for Mi Band, which allows you to flexibly adjust vibrations, create complex notification scenarios, and even control music on your phone directly from the wristband, and is especially useful for users who don’t feel like standard Mi Fit functionality is enough.
Using these gates requires additional permissions, including access to notifications and special features. Once you install and configure Notify, the standard Mi Fit application can be kept closed, as all synchronization and control functions will take over the new tool, which also allows you to bypass some of the limitations of the operating system on the background of the applications.
It is worth noting that the use of third-party add-ons can increase the battery consumption of both the phone and the bracelet itself due to more frequent data transfer, so it is recommended to first fully configure the basic functionality through the official application and only then move to advanced settings if there is a real need for them.
Should I use Notify for Mi Band?
Another important feature that's available after you connect is phone search. If you lose your smartphone within your apartment, you can activate a search through the wristband menu, and the phone will start ringing loudly even if it's in silent mode. This only works when you're actively connecting over Bluetooth.
Connection stability depends on the version of the operating system and the status of the Bluetooth module. Below is a table of compatibility and requirements for the correct operation of the phone-Xiaomi Band 4 bundle.
| Parameter | Requirement/Status | Note |
|---|---|---|
| Android version | Android 5.0 and higher | Recommended Android 8.0+ |
| iOS version | iOS 10.0 and higher | For iPhone 5s and newer |
| Bluetooth | Bluetooth 4.0 BLE | Low Energy is a must for you. |
| Screen resolution | 1280x720 and higher | For the correct display of the interface |
| Phone memory | Free 100MB | For data caching and updates |
If your phone meets all the requirements, but the connection is constantly broken, try “forgetting” the device in the Bluetooth settings and doing the pairing again. Sometimes cleaning the Mi Fit app cache through the phone’s app settings helps.
Also make sure you have the latest version of the app installed. Developers regularly release patches that improve connection stability with different smartphone models. Older versions of the software may conflict with new Android security updates.
During operation, you may notice that the bracelet has stopped vibrating when alerted or that the steps are not updated. First, check if the bracelet is not in Do Not Disturb mode (moon icon), in which the notifications are blocked programmatically.
If the problem is no steps, make sure the pulse sensor is tightly attached to the wrist and does not hang around. The motion sensor (accelerometer) only works correctly when the device is properly positioned. Also check if the data synchronization in the application itself is disabled.
⚠️ Warning: Do not let moisture enter the bracelet charging pins before connecting to the charger or computer.Although the model has spray protection, oxidation of the contacts can lead to data transmission or charging errors.
In rare cases, a complete reboot helps: turn off Bluetooth on your phone, turn off the phone itself, wait a minute, turn on the phone and reconnect. This resets the Bluetooth stack errors that may have accumulated over time.
💡
To extend the life of the bracelet battery, turn off constant monitoring of the pulse (leave the measurement once every 10-30 minutes) and reduce the brightness of the screen. This will increase the autonomy to 15-20 days.
The Xiaomi Smart Band 4, when properly set up and connected, transforms it from a simple step counter to a powerful personal assistant. Regular data synchronization allows you to track health dynamics, analyze sleep phases and respond to changes in the body. Don't ignore firmware updates, as they often contain improvements to calorie counting and heart rate algorithms.
Remember, not only is the device working properly, but the settings of your smartphone are also key to a stable experience. Resolutions, background processes, and app versions play a critical role in how often your phone will lose the bracelet. Pay attention to these details when you first set up.
Now that you know how to connect your phone to a Xiaomi 4 watch and troubleshoot possible issues, you can enjoy all the benefits of wearable electronics. keep an eye out for app updates and experiment with settings to find the perfect balance between functionality and power consumption.
💡
The main secret to stable operation is to allow the Mi Fit app full access to work in the background and disable aggressive energy savings for this process in Android settings.
