Wearable electronics have become an integral part of the lives of millions of users, and the Xiaomi Mi Band 4 remains one of the most popular fitness trackers due to its price-performance ratio.However, the initial setup process can seem confusing for those who are first encountering the Chinese manufacturer's ecosystem. Proper pairing of devices is the foundation for stable operation of all functions, from heart rate tracking to notifications.
In this guide, we will take a look at all the steps in activating a gadget, from preparing your smartphone to fine-tuning your in-app settings. You will learn how to avoid typical Bluetooth connection errors and why standard phone settings can block your tracker.
There are a few critical issues that are often overlooked, such as the need to remove an old device from the system menu before a new pairing attempt, and we will focus on the differences between Android and iOS, as their approaches to security resolutions differ significantly.
Preparation for the initial start and charging
Before trying to connect the tracker to a smartphone, you need to make sure that the device's battery has enough charge. Often new gadgets come with minimal energy, and trying to turn them on may be unsuccessful. Connect the capsule to the charging cable and wait for the battery icon to appear on the screen.
It is important to understand that charging should only be done with original or certified cable, as using cheap analogues can damage the power controller. Contacts on the back of the capsule and on the cable should be clean and dry. If the tracker does not respond to the connection, try to wipe the contacts with dry cloth.
⚠️ Warning: Do not leave your device unattended overnight for the first time, especially if the battery has been completely discharged for a long time.
Once the logo appears on the screen, you can move on to the next step: make sure your smartphone meets the minimum system requirements: Android 4.4 or iOS 9.0 and higher. Also check that the wireless module is activated in the phone settings.
- 🔋 Charge the tracker to minimum. 20-30% before first incorporation.
- 📱 Make sure your smartphone has Bluetooth and geolocation enabled.
- 🧹 Clear the contacts of the charger and tracker from oxides.
Installation and configuration of the Mi Fit application
A key element of the ecosystem is a specialized application, now known as Zepp Life (formerly Mi Fit), which is the software package that first registers the device, updates the firmware and synchronizes health data, and downloads the app from official Google Play stores or the App Store.
Once installed, you need to create an account or log in to an existing one using an email or phone number, registration is mandatory, because without a Mi Account account, the tracker will not be able to transfer data to the cloud and work correctly. Carefully fill out the profile with real height, weight and date of birth, as these parameters depend on the accuracy of calorie calculations and steps.
During the setup process, the app will request a number of permissions to access data. It is critical to provide access to geolocation, notifications and background work of the application. Without these permissions, the Xiaomi Mi Band 4 can permanently lose communication with the phone or not display incoming messages.
- 📲 Download the Zepp Life app from the official store.
- 📝 Register using the current phone number.
- 🔐 Provide all required permits for stable operation.
The process of pairing the tracker with a smartphone
The process of connecting Xiaomi Mi Band 4 is carried out exclusively through the application interface, and not through the standard Bluetooth menu of the smartphone. Trying to find and connect the bracelet through the system settings of the phone will lead to pairing error or unstable operation.
Open the app and go to the Profile tab at the bottom menu. Click on Add Device and select from the list of Mi Band 4. The app will then start scanning available devices within range. The tracker screen should show a vibration signal and a request for confirmation of pairing.
⚠️ Note: If your phone’s Bluetooth list already has a record of Mi Band 4, be sure to delete it (“Forget the device”) before setting up via the app.
Tap the bracelet image on your smartphone screen for confirmation, at which point encryption keys will be exchanged, and the devices will be connected, and successful connection will be confirmed by vibration and display of the current time on the tracker screen.
☑️ Checklist of successful pairing
Once the connection is successful, the app will prompt you to update the firmware of the device. Never interrupt the firmware update process if the charge level is below 50%, as this can turn the tracker into a “brick.” Wait for the installation to be completed and the gadget to automatically restart.
Configure notifications and notification functions
One of the main features of the Mi Band 4 is to display notifications. To make them come to your wrist, you need to manually activate the desired applications in the device profile settings. In the "Application Notices" section, you will find a list of all the programs installed on the phone.
Turn on switches in front of the apps you want to see messages from: messengers, social networks, email clients. It is important to note that the text of the notification often depends on the settings of the application and the operating system. Android may need to enable access to notifications in the system settings.
You can also customize your call displays, you can choose Vibration Only, Vibration and Name, or you can opt out of call notifications completely, which is convenient when you're in a meeting or in a movie, but you want to make sure you don't miss an important call.
💡
To save battery power, turn off notifications from games and news feeds, leaving only important messengers and calls.
- 📩 Activate toggles for WhatsApp, Telegram and other instant messengers.
- 📞 Set up the format of incoming calls.
- 🔕 Use the “Do Not Disturb” mode on your schedule.
Solving Connection and Synchronization Problems
Even if all instructions are followed, technical difficulties can occur, and a common problem is when the application does not see the tracker or constantly loses contact with it, and the first thing to check is whether the connection is not worth sleeping due to aggressive energy savings.
On Android smartphones with MIUI shells, EMUI or other custom firmware, the system can force the background processes to close, you need to find the Zepp Life application in the installed list, go to Battery and select No Limits mode, and you should also fix the application in memory so that it does not unload.
Hidden Bluetooth settings
If the problem persists, try resetting the tracker completely. On the bracelet itself, find Reset and confirm the action, then remove the device from the app and try reconnecting it as new.
💡
The stability of the Mi Band 4 depends on 90% of the correct energy saving settings in the smartphone operating system.
