How to connect Xiaomi Mi Band 4 to your phone

Modern wearables have become an integral part of the lives of millions of people who monitor their health and fitness. The smart bracelet allows you to track your heart rate, step count and sleep quality, while remaining a compact accessory. However, the initial setup of the device often raises questions for beginners who have just unpacked a purchase.

The process of synchronizing Xiaomi Mi Smart Band 4 with a mobile phone takes only a few minutes, but requires compliance with a certain algorithm of actions. Errors during the pairing stage can lead to the fact that the gadget will not correctly transmit data or work in the background. In this article, we will discuss in detail all the stages of connection, setting up notifications and solving typical problems.

To get started, you’ll need an activity tracker that’s at least 20 percent charged and a modern smartphone that supports Bluetooth 4.0 or higher. It’s important to pre-prepared your phone’s operating system by upgrading to the current version, as older firmware sometimes conflicts with newer versions of apps. Without installing the official Mi Fit (Zepp Life) or Xiaomi Wear app, the full functionality of the bracelet will not be available.

Preparation of the device and operating system

Before you go to the software part, you need to make sure that the gadget is physically ready. If you just took the device out of the box, it can be in deep sleep mode to save battery energy when stored in stock. Usually activation occurs automatically when you connect to the charger, but sometimes you need to force it to turn on.

Make sure your smartphone has a wireless module on, in some cases, the system may block peripheral operation for safety or charge saving reasons, and check that geolocation (GPS) is activated, as in Android it is a mandatory requirement to scan Bluetooth devices near you.

⚠️ 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 device will not be able to transfer data to the application.

The operating system must meet the minimum requirements: Android 5.0 and above or iOS 10.0 and higher. On Xiaomi, Redmi and Poco devices with a MIUI or HyperOS shell, it is recommended to additionally configure permissions for the companion application so that the system does not “kill” the sync process in the background.

💡

Before you start setting up, clear the list of previously paired Bluetooth devices in your phone’s settings to avoid address conflicts.

Installation and configuration of a companion application

A key element of the ecosystem is software that acts as a bridge between the wearable device and the Internet. The fourth generation model was originally designed to use the Mi Fit app, which was later renamed Zepp Life. It also supports work through the Xiaomi Wear (Mi Wear) app, which has a more modern interface but may require an additional plugin for older trackers.

Download the program should be exclusively from official sources: Google Play Market for Android or App Store for iOS. APK-files or modified versions may lead to personal data leakage or unstable synchronization. Once installed, the application will request an account creation or login through an existing Mi Account profile, Google or Apple ID.

When you register, it's important to have the right anthropometrics, height, weight, and date of birth, and based on those parameters, algorithms will calculate calorie expenditure and analyze sleep phases, and if you skip this step or type in the wrong numbers, the statistics will be incorrect, and motivation to exercise may be lost.

Once you log in, you need to give the app all the permissions you want, which is Bluetooth, geolocation, notifications and auto-start, and without those permissions, the fitness tracker won't be able to display incoming calls or messages from messengers on its display.

The process of pairing the bracelet with the phone

When the preparatory steps are complete, you can go to the direct connection of devices. Launch the application on your smartphone and go to the Profile tab or click on the add-on icon (usually the plus in the upper right corner), the system will prompt you to select the type of device from the list.

Find the list of "Mi Smart Band 4" and click on it. At this point, the vibrating signal and the request for confirmation of pairing (phone icon or checkmark) should appear on the tracker screen. Click on the touch screen area of the bracelet to confirm the action. If the request does not appear, try rebooting the gadget through the settings menu.

Once the procedure is completed, the main dashboard with the current pedometer readings will be displayed on the smartphone screen, from which point the automatic statistics will be collected. If the process is interrupted, check if the device is connected to another phone, since the bracelet can only hold one active connection.

Setup of notifications and notifications of applications

One of the main features of the Mi Band 4 is that you can receive notifications about calls and messages right on your wrist, and to activate this option, you need to go to the settings of the device inside the application and select "Application Notifications", which opens a list of all the programs installed on the phone.

Activate the switches opposite the apps you want to see on your wristband: WhatsApp, Telegram, Viber, SMS, calls, etc. Please note that the text of the notification will only appear if it is visible in the notification curtain of Android or iOS. Hidden or secret messages will not be displayed.

⚠️ Attention: On smartphones Xiaomi with a shell MIUI You must manually allow AutoRun for the Zepp Life application and fix it in memory, otherwise notifications may come with a delay or not come at all.

You can also set up Do Not Disturb mode in this section, and at a given time, the bracelet will only vibrate when critical events are detected, ignoring the usual messages, and this is especially useful during sleep or meetings, when constant vibrations can interfere.

How do emojis display?
Mi Band 4 supports displaying some standard emojis from notifications, but complex or new emojis can be displayed as squares or replaced with text description due to the limitations of fonts in the device's firmware.

For incoming calls, you can display the contact name if it's stored in the phone book of your smartphone. If the number isn't recorded, the bracelet will show just numbers. You can't turn it down with the bracelet, but you can quickly see who's calling and decide whether to answer or not.

Calibration and personalization of the interface

Once you've set up the basics, it makes sense to personalize it so you can use it as comfortably as possible. You can change the dials right from the app. You can have a lot of options available in the library, from minimalistic blacks to complex animated designs.

An important step is calibrating the sensors, and walking a known distance (like 400 meters in the stadium) with GPS on your phone and running tracking in the app, will help the system calculate your step length more accurately, and therefore the distance and speed when walking without connecting to a satellite.

In Profile, you can set your goals by step, sleep time, and activity. A smart algorithm will analyze your achievements and praise you for completing your plans, or motivate you if you're lazy. It also adjusts your wrist lift to turn on the screen, and you can select the sensitivity and time intervals of this feature.

💡

Personalizing your dial and activity goals increases the likelihood that you will wear the bracelet constantly without removing it.

Remember to adjust your pulsemeter. You can choose to measure once per minute, once every 10 minutes, or only on request. Frequent measurements improve accuracy, but they can consume battery power faster, although this is not as critical for a screenless model as for screenless versions.

Solving Connection Problems and Errors

Despite the simplicity of the procedure, users sometimes face difficulties. The most common problem is that the phone does not see the bracelet. In this case, you need to make sure that the device is not connected to another smartphone. Mi Band 4 can store several phones in memory, but the active connection is only one.

If the bracelet is stuck and doesn't respond to touch, you can reboot it. Put the device on charge, which often causes a forced restart of the system. You can also find System or Additional on the brace menu and select Break Communication or Reset, and then repeat the pairing procedure.

⚠️ Warning: If the app says “Device is busy” or “Connection error”, try to completely uninstall the app, restart the phone, install the app again and re-register your account.

Data sync issues are often solved by clearing the app's cache. Go to your phone's settings, find the Zepp Life app, select Memory and click Clear Cache. Don't confuse it with Clear Data, as this may require a repeat login.

What to do if the bracelet is warm?
A little heat when charging or updating the firmware is normal. If the device is hot on standby, try resetting it to factory settings. If the heating continues, it may be a battery defect.

In rare cases, a full factory reset is required, which will remove all the accumulated statistics on the device itself (but not in the application cloud) and return all settings to their original settings. Use this method only if other methods have not helped to establish stable operation.

Why does the bracelet not charge after connection?
Check the contacts on the back of the bracelet and on the charger. They should be clean and dry. If the contacts are oxidized, wipe them with alcohol. USB-The computer port or phone adapter provides sufficient current (preferably at least 0.5 A).
Can I connect Mi Band 4 to two phones at the same time?
Officially, the device only supports one active connection, but if you log in to the same account on two phones, the data will be synced to the cloud, but for notifications, you will need to manually switch the Bluetooth connection between the devices.
How to break off communication with your phone before selling?
In the app, go to the device profile and select Unbind. Then, on the bracelet itself, in the menu, look for Factory Reset, which will delete all your personal data from the tracker's memory.
Do I need the internet to work with the bracelet?
For initial setup and synchronization with the server, yes. However, the tracker itself can operate autonomously, recording steps and pulses without the Internet, and the data will be stored in memory and transmitted to the phone when the connection is restored.
