Integrating wearable electronics into the Apple ecosystem always requires special attention, especially when it comes to popular fitness trackers from Xiaomi. iPhone users often face nuances of pairing that are not obvious when they first get acquainted with the device. Properly configured Mi Band 4 allows you to unlock the full potential of the gadget, turning it from a simple pedometer into a powerful tool for monitoring health.
The connection process is not complicated, but requires a strict sequence of actions, ignoring which can lead to synchronization errors or no push notifications. Unlike Android smartphones, where the system is more flexible, iOS dictates its rules for working with background processes and Bluetooth connections, which is why it is important to complete all the preparatory steps before you first click the device search button.
In this guide, we will take a detailed look at every step, from operating system preparation to fine-tuning notifications, learn how to avoid common bugs and make the tracker work consistently in conjunction with iOS. Proper setup will ensure you have long battery life and the accuracy of the data collected on physical activity.
Preparing iPhone to pair with tracker
Before starting the procedure, make sure that your smartphone meets the minimum system requirements. For stable operation of the Mi Fit (or Zepp) application, you need an operating system version at least iOS 10.0, although for current functions it is better to use more recent releases. Check the availability of free space and a stable Internet connection, as the first run will require downloading additional data packets and fonts.
The critical thing is to manage Bluetooth connections, and many users make the mistake of trying to tuck the bracelet directly into the iPhone system settings, which is absolutely impossible because the system will reserve the communication channel and the app will not be able to find the device, and you first have to delete all the old records about Xiaomi trackers if they previously connected to this phone.
To clean the list of associated devices, perform the following actions:
- 📱 Open your iPhone Settings and go to Bluetooth.
- 🔍 In the list of “My devices” find a record Mi Band 4 or similar.
- ❌ Click on the information icon “i” and select “Forget this device».
- 🔄 Reboot your smartphone to reset the cache of network services.
⚠️ Warning: If you see a device in the Bluetooth list but it doesn’t delete or hangs “Not Connected” status, try rebooting the bracelet itself through the settings menu on the tracker screen before trying to delete it again.
Make sure geolocation is enabled globally for the system as it is a mandatory requirement for Apple to operate any Bluetooth accessories transmitting location or activity data.Without this permission, the app simply won't see the tracker in search radius.
Installation and configuration of the Mi Fit (Zepp) application
The main control center for your fitness bracelet is the mobile app. At the moment, the functionality is gradually transferred to the Zepp app, but the classic Mi Fit still supports Mi Band 4. It is recommended to download the latest available version from the official App Store to avoid compatibility and data security issues.
Once you install the app, you need to register for an account or log in to an existing one. Xiaomi Account support allows you to synchronize data between different devices and services. When you first log in, the system will request a number of permissions that you need to take care of, as they affect functionality.
Mandatory permits for correct operation:
- 📍 Geoposition: Select Always or When in use, otherwise you won’t be able to find the device.
- 🔔 Notifications: Allow push messages to be sent to see calls and messages on your wrist.
- 💪 Fitness and movement: necessary for recording steps and analyzing sleep in conjunction with HealthKit.
- 📶 Local area network: required to search for devices in the local segment of the Bluetooth network.
💡
It is recommended to enter the iPhone privacy settings (Settings → Privacy) and manually check that the Mi Fit app is allowed to use all the requested features.
The interface of the application may seem overloaded, but for the initial setup, we only need the Profile tab. This is where new hardware is added. Don't try to search for the device on the home screen until you have completed your account registration.
The process of searching and connecting the device
After successful authorization, go to the Profile tab in the lower right corner of the screen. Here you will see the Add Device button or the + icon. Click on it and select Mi Band 4 from the list of available gadgets. The application will warn you to keep your phone next to the bracelet.
The scanning process will start, at which point a pairing request or vibration signal may appear on the tracker screen, if the bracelet is new, it is in the default mode (pairing) and if it was in use, you may need to reset it to factory settings through the tracker's menu itself.
Technical parameters of the connection for successful synchronization:
| Parameter | Value/Requirement | Note |
|---|---|---|
| Protocol | Bluetooth 5.0 LE | Low energy consumption |
| Distance | Up to 10 meters. | No problem. |
| Battery charge | More than 20% | For a stable search |
| Bracelet version | Anybody. | Update when connected |
When the app detects the tracker, the device and the Confirm button will appear on the iPhone screen, while the Mi Band 4 displays a vibration icon or confirmation button. Press the bracelet screen (or touch the touch zone) to confirm pairing, taking 10 to 30 seconds.
☑️ Checklist of successful connection
If the search lasts more than 2 minutes and nothing happens, try closing the application completely (swipe up from the menu of running applications) and running it again.
Updating firmware and installing language
Immediately after the binding, the application will offer to update the tracker software. This is a critical step, since the factory firmware may contain errors or not have Russian localization. Without updating to version 1.0.9.66 and higher, Russian on the Mi Band 4 may be missing or incorrectly displayed.
The upgrade process requires a stable connection and a battery charge of at least 50%. Do not interrupt the process and keep the phone next to the bracelet. The tracker screen will show the progress bar, and the phone can emit beeps at the end of the stages.
Procedure for updating:
- In the application, go to the profile of the device.
- Find the Software Version or Update Check.
- Click Update and wait for the package to load.
- Confirm the bracelet on the screen.
⚠️ Warning: During the upgrade, the bracelet screen may go out and light up again. Do not try to reset the device or move away to a distance that interrupts the Bluetooth signal, otherwise the tracker may turn into a brick».
What if the update is 99% down?
After successfully installing the new version, a choice of language will appear in the wristband menu. Go to the tracker settings, find the Language item and select Russian (or English, if the Russian localization has not yet been loaded, sometimes you need double switching).
Setup of notifications and data synchronization
One of the main features of the Mi Band 4 is to display notifications. To make them come, you need to allow the application to access them in the iOS system settings. Go to iPhone Settings, look in the Mi Fit application list and make sure that the Notifications switch is activated.
Then you can set up filters inside the app itself, and you can choose which apps will duplicate your wrist messages, whether it's messengers, social media, mail, or calls, and remember that the text of the message is only displayed when it comes in, and the story is not stored on the wristband.
List of customizable notification parameters:
- 📞 Incoming calls: display contact name and reset button (deviations).
- 💬 Communications: SMS, iMessage, WhatsApp, Telegram, Viber and others.
- 📅 Calendar: Reminders of meetings.
- 🌧️ Weather: Automatic data updates when synchronized.
To sync your health data with your native Health app, go to your profile in the Mi Fit app, select Settings → Add Accounts → Apple Health. Allow reading and writing of all data categories, and combine steps and sleep statistics from multiple sources.
Note that to work notifications, the Mi Fit application must have permission to work in the background. iOS aggressively unloads background processes, so sometimes you need to open the application manually for instant synchronization of accumulated data.
Problem Solving and FAQ
Even with a clear follow-up, technical difficulties can arise, most often due to Bluetooth features in iOS or software version conflicts. If the bracelet is not visible, make sure it is not connected to another phone within range. Mi Band 4 can only connect to one device at a time.
A common problem is that the bracelet loses communication at night or stops vibrating when alerted, which may be due to the iPhone's power saving mode, check if the phone is in "Do Not Disturb" or "Sleep" mode, which can block data transmission to the periphery, and reconnecting to the Bluetooth menu also helps.
If the tracker shows the wrong time, check the time zone in the iPhone settings. The bracelet has no real-time clock of its own and relies entirely on the smartphone time when synchronized. The difference in time zones will result in alarm clocks and sleep data being desynchronized.
⚠️ Attention: If the bracelet has stopped responding to touch and is not activated when charged, the contacts may have oxidized. Wipe the metal contacts on the back with an alcohol wipe and try charging the device.
💡
In 90% of cases, connection problems are solved by completely removing the device from the iPhone’s Bluetooth settings and re-associating through the app from scratch.
Third-party utilities can be used for deep diagnostics, but they require caution. Xiaomi official support recommends using only certified charging accessories, since cheap cables may not provide enough current to start the bootloader when the device is “reviving”.
