Integrating the Android gadget ecosystem into the iOS environment is a task that often raises questions among users who have decided to combine an Apple smartphone and wearable electronics from a Chinese manufacturer. The owner of the iPhone 12 gets his hands on a powerful tool with an excellent display and stable operation, but for full use of activity trackers or Xiaomi smart watches, the correct initial configuration is required. This process is not as complex as it may seem at first glance, but it has its own technical nuances, ignoring which leads to unstable operation of the Bluetooth connection.
The main challenge is that the iOS operating system has stricter background constraints than Android.This means that standard methods of finding devices through Bluetooth settings may not work or work properly.You need to use specialized software that acts as a bridge between the watch hardware and the phone's operating system. Without installing the right application, synchronizing health and fitness tracks data will not be possible.
In this article, we will take a look at the algorithm that ensures that your gadgets pair successfully. We will look at the choice of application, the registration process, setting permissions and solving typical connection problems. Following the instructions will help you avoid common mistakes when the watch sees the phone but cannot transmit data, or when notifications stop coming after unlocking the smartphone screen.
Choosing the Right Application for Management
The first and most critical step is to install the right software. In the past, the situation with the software for wearable devices was confusing: there were Mi Fit, Zepp Life and Mi Wear. At the moment, for most new Xiaomi watches and bracelets, such as the Mi Band 6/7/8 or Mi Watch, the main and recommended application for iPhone users is Mi Fitness (formerly known as Xiaomi Wear), which provides the best compatibility with iOS 15 and newer, which are installed on the iPhone 12.
You should download the program exclusively from the official App Store. Using third-party sources or modified versions of applications can lead to personal data leakage or malfunction of health monitoring functions. After downloading and installing the application, you will need to create a Mi Account or log in to an existing one. This is necessary for cloud storage of statistics and data synchronization between devices.
Importantly, the old Mi Fit app has now been renamed Zepp Life and is focused mainly on Amazfit brand devices, although it supports some older Xiaomi models.If you have a new watch model released after 2021, Mi Fitness will be the only true choice.Make sure in the phone's privacy settings you have consented to use movement and fitness data, otherwise the app won't be able to read steps.
Preparing iPhone 12 and the clock to pair
Before you go directly to search for the device, you need to prepare both gadgets. On the iPhone 12 side, you should make sure that the Bluetooth module is activated and visible to other devices. Also critical is the presence of a stable Internet connection, since the first start of the application will download the necessary drivers and profiles of devices from the server.
The watch itself must also be ready to go. If the device is new, it will likely turn on automatically when removed from the package or when connected to a charger. If the watch has been used with another phone, it must be reset to factory settings. This is done through the settings menu on the watch itself or through the app on the old phone. Ignoring this step is a common reason why the iPhone 12 doesn't see the watch or writes about pairing errors.
☑️ Connection readiness
It is recommended to bring the watch as close to the smartphone as possible, removing any physical obstacles. 10-15 You can see the clock in centimeters at the time of the initial handshake request. QR-If the screen is gone, tap it or press the side button to activate the display.
⚠️ Warning: Do not attempt to pair your device through the standard Bluetooth menu in iOS settings.This will lead to an error, as Apple’s security system blocks a direct connection without authorization through an intermediary app.
Step-by-step instructions for connecting
The synchronization process in the Mi Fitness application is standardized, but requires care when entering confirmation codes. After launching the application and logging into your account, go to the Device tab at the bottom menu. Click the Add device button, usually located in the upper right corner or in the center of the screen.
The app will start scanning the space. The device list should show the name of your model, for example, Mi Band 7 or Mi Watch Lite. Click on it. The iPhone 12 screen and the watch will have a digital code. You need to make sure the numbers are identical, and confirm the action on both devices. On the watch it is usually a button with a tick, on the phone it is a confirmation pop-up.
When you install the connection, you may need to update the firmware of the watch. This is normal: new devices often come with an older version of the software that is not optimized for the latest versions of iOS. Wait until the download and install updates are completed without turning off the smartphone screen and without blocking the application.
What to do if the code does not appear?
Once paired successfully, the app will suggest setting up notifications, which is a key step in getting push notifications from messengers, allowing access to contacts, notifications and geolocation, and without these permissions, the smartwatch will be severely limited, making it a simple pedometer.
Set up iOS notifications and permissions
The iOS operating system is known for its strict security policies, which often strangle the background processes of third-party apps.To get notifications from WhatsApp, Telegram or calls to come to the wrist, you need to perform a number of additional actions in the settings of the iPhone 12 itself.
Go to Settings → Mi Fitness (or the name of the application you use). You need to manually turn on all switches, especially those related to background activity. Make sure you allow access to Notifications, Locations (select Always or When using) and Bluetooth. If you deny access to geo-position, the jogging route tracking function will not work.
| Permission | Why? | Recommended status |
|---|---|---|
| Bluetooth | Clock connection | Included. |
| Notifications | Transfer of watches | Permitted. |
| Geoposition | Tracking training | Always / When used |
| Fitness and movement | Synchronization of steps | Included. |
| Local area network | Finding devices on a Wi-Fi network | Included. |
You should pay special attention to the settings of specific applications. In the menu of the watch app itself (Profile or Device Settings), find the item "App Management" or "Application Notifications" and check the boxes against the social networks you want to see on the watch, and if the app is not on the list, it will not be able to transmit data.
💡
For stable notifications on iOS, it is recommended to disable the charge saving for the Mi Fitness application in the iPhone battery settings. This will prevent the system from forcing the synchronization process to end.
Synchronizing Health and Apple Health Data
One of the main reasons for buying an iPhone tracker is to see all the statistics in one place. Apple's ecosystem allows you to aggregate data from different sources through the Apple Health app. To make the steps, pulse and sleep recorded by Xiaomi watches appear in the native Apple app, you need to set up data export.
In the Mi Fitness app, go to your user profile. Find the Add Accounts or Third-Party Data section. Select Apple Health. The system will request confirmation for sync. You will be asked to select which data is allowed to be transferred from the watch to Apple Health and vice versa. It is recommended to include all categories: steps, distance, pulse, sleep, weight.
It's important to understand the difference between one-way and two-way synchronization. Most of the time, data flows from the watch to Apple Health, but not vice versa. Which means that if you manually add a workout to Apple Health, it won't appear in the watch app. However, all the statistics from the wrist will be correctly accounted for in the overall activity rings of the iPhone 12.
⚠️ Note: When you enable sync with Apple Health, you may experience duplicate steps if you also have a third-party meter installed on your phone.In Apple Health settings, you can prioritize data sources by putting your Xiaomi watch above the built-in iPhone tracker.
Solution: The clock is not connected or switched off
Even if you follow all the instructions, you can have technical failures. The most common problem is that the watch is visible on the Bluetooth list, but the app says "Disconnected" or "Device is busy." This means that the phone has "captured" the device at the system level, preventing the app from taking control. Solution: go to Settings → Bluetooth, find your watch, click on the icon (i) and select "Forget this device."
Another common situation is constant connection breaks. iPhone 12 is equipped with a Bluetooth 5.0 module, which should provide stable communication, but interference from Wi-Fi routers or other gadgets can affect the signal. → Mainstream → Removing or resetting iPhone → Reset → Reset network settings. This won't delete personal data, but will update the configuration of wireless modules.
If nothing works, do a full factory reset. On touchscreen models, this is done via the Settings menu → System → Reset. On non-screen bracelets, you often need to pinch the touch button for 15-20 seconds or use the Untie feature in the app before re-searching.
💡
90% of connection problems are solved by completely removing the device from the Bluetooth list in iOS and re-associating exclusively through the Mi Fitness app.
