How to connect the Xiaomi Mi Band 4 fitness bracelet to your phone

Modern wearables have become an integral part of the smart home ecosystem, and the Xiaomi Mi Band 4 remains one of the most popular devices in its class thanks to its excellent price-performance balance.The process of initial activation and pairing can seem confusing for beginners, especially given the changes in software over the years.

Before you start syncing, you need to make sure your smartphone meets the minimum system requirements, usually having a Bluetooth 4.0 module or higher, and an up-to-date version of the Android or iOS operating system. Ignoring pre-preparation often leads to the phone simply “not seeing” the tracker in the list of available devices.

It is important to understand that simply turning on the bracelet is not enough – you need a special intermediary application. Standard Bluetooth settings in the phone system are not designed for deep integration with the functionality of the Mi Band. The entire management process, from setting the time to updating the firmware, occurs exclusively through the manufacturer’s proprietary software.

Preparation of the device and smartphone for synchronization

The first step is to physically activate the tracker. Charge the device to at least 20-30%, as at low charge, the Bluetooth module may not work stable or at all. Use the original cable or proven analogue with a 2-pin connector to avoid problems with the supply of voltage.

You need to activate geolocation on your smartphone, which is a requirement of the Android operating system for applications that scan Bluetooth devices in the background. Without GPS on, finding the bracelet in the application may not be successful even if the wireless module itself is active.

⚠️ Warning: Do not try to connect the bracelet directly through the standard Bluetooth menu in the phone settings.This will lead to a pairing error, and the application will not be able to find the device in the future.

It’s also worth checking if there’s any space in the phone’s memory. The management app weighs a bit, but it takes some reserve to accumulate statistics and caching data. Clearing the cache of old, unused programs can speed up the installation and initial setup process.

Selecting and installing the right application

The fourth version of the bracelet has historically been used by Mi Fit, but recently Xiaomi and partner Huami have been migrating users to the Zepp Life platform, not just a name change, but a full-fledged update to the interface and server architecture.

Download the program should only be from official stores: Google Play for Android or App Store for iOS. APK-files from third-party resources may lead to leakage of personal health data or incorrect notifications.

• 📱 Zepp Life – a recommended app with a modern design and full support for Mi Band 4.
• ⌚ Mi Fit is a classic app that still works but gets fewer updates.
• 🌍 Region – when registering, it is important to choose the right region (usually Russia or China) so that the server processes the data correctly.

Once installed, you need to register an account, use your phone number, email address, or log in through existing social media profiles, and have a strong password and phone number linking make it easier to restore access if you change your device.

Step-by-step instructions for connecting the bracelet

Launch the app and log in to your account. Go to the Profile tab (the human icon in the lower right corner). At the top of the screen, find the Add Device or Add Device button. The system will prompt you to select the device type from the list.

From the list of available gadgets, select Mi Band 4. The app will request permission to use Bluetooth and geolocation - confirm both requests. Now the search indicator will appear on the smartphone screen, and the Bluetooth icon or vibration signal confirming the pairing mode should light up on the bracelet screen.

When your tracker appears on the list of found devices (usually designated as Mi Band 4 or serial number), click on it. The bracelet screen will request confirmation of pairing with the symbol "✓". Click on the tracker touch button for confirmation.

It takes 10 to 30 seconds to complete the process, and once you connect successfully, the app will download the basic settings, set the time to date, and suggest you upgrade the firmware, and you shouldn't opt out of the update, because newer versions of firmware often contain sensor bug fixes.

Set up notifications and health features

Once paired successfully, you can access a fine-tuning, so in the device menu, you can choose which notifications will come to your wrist, which can be calls, SMS, messages from messengers or notifications from social networks.

To correctly display the text of messages in Russian, you need to allow access to notifications for all necessary programs in the application settings. On Android, this is done through the Settings menu → Applications → Special features → Access to notifications.

Pay special attention to setting activity targets, you can calibrate the calorie counter and the stepmeter to your weight and height, which will improve the accuracy of the calculations, and the app also offers a feature called Motion Reminder, which will vibrate if you sit still for a long time.

💡

For maximum autonomy, turn off constant heart rate monitoring, leaving the measurement on schedule or manually, this will prolong the bracelet's operation by 3-5 days.

Solution: if the bracelet is not connected

The most common problem is that the phone sees the device, but the connection is reset, in which case, try removing the device from the list of paired devices in the Bluetooth system settings and in the Zepp Life app itself.

Sometimes it helps to completely reset the bracelet to the factory settings, you need to find the System menu (the gear icon) and select Unbind. Then repeat the pairing procedure as if you first turned on.

⚠️ Note: If the bracelet was previously linked to another account, it must be untie in the old profile, otherwise the new phone will not be able to obtain administrator rights for the device.

Problems can arise from energy saving. Modern smartphones aggressively kill background processes. Add Zepp Life to battery exclusions and allow auto-start. This will prevent communication from breaking when the phone screen is out.

Update of firmware and calibration

Regular software updates are key to stable operation. The app will have a red dot in the profile of the device if a new version is available. The upgrade process requires that the bracelet be near the phone (no more than 1 meter) and have a charge of more than 50%.

During the upgrade, the bracelet screen may go out and the progress bar will freeze for a few minutes. This is normal behavior, you can not interrupt the process. If the upgrade was unsuccessful, the bracelet may require a connection to the charger for recovery.

• 🔄 Stability – New versions improve step-counting algorithms.
• 💓 Accuracy - the algorithms of the optical pulse sensor are updated.
• 🔋 Energy – optimized charge consumption in standby mode.

After the update, it is recommended to calibrate. Go a known distance (for example, 100 meters) and check the bracelet data with reality. In the application, you can enter the length of your step manually to improve the accuracy of tracking.
