Integrating wearable electronics into the Xiaomi ecosystem is a process that at first glance seems trivial, but owners of the popular Redmi 8 smartphone often face a number of specific nuances. Although both devices are manufactured by the same corporation, the operating system versions differ. MIUI Bluetooth protocols can create temporary obstacles during initial launch. MIUI This will prevent most of the typical synchronization errors.
Modern smartwatches require not just a mechanical radio connection, but a full software bundle through specialized aggregator applications. In the case of the Xiaomi ecosystem, the key element is the link between the watch firmware and a mobile app that broadcasts health data and notifications. For Redmi 8, which runs on Android 9 or 10 (depending on updates), it is critical to properly configure access rights, as aggressive energy saving policies can interrupt the connection.
In this article, we will take a closer look at each step of the process, focusing on hidden settings that are often overlooked, how to avoid data desynchronization, why the watch may not ring on an incoming call, and how to keep it running autonomously without losing functionality.
Preparation of devices for primary pairing
Before you start any software manipulation, you need to make sure that both devices are physically ready to interact. Charge your smartwatch and Redmi 8 smartphone to at least 40-50%, as the process of initial installation and updating the firmware accessories can be energy intensive. Low battery power often leads to interruption of system files writing, which can cause errors in the Bluetooth module.
Make sure your Redmi 8 has geolocation enabled. This is a requirement of the Android operating system to work with Bluetooth scanning in the background, and without active GPS-The app module simply won’t see your watch, and it’s also a good idea to clear the Bluetooth cache in your phone’s settings if you’ve previously connected to a lot of other devices to avoid addressing conflicts.
☑️ Checking before connection
An important step is to reset the previous settings on the watch if they were previously used with another phone. Go to the device menu and find System → Untie or press the touch button to enter reset mode. Pairing with the new device is possible only after the accessory memory is completely cleared from the old profiles.
Selecting and installing the right application
Xiaomi’s ecosystem uses two main applications for wearable electronics, and choosing the right one depends on the specific model of your watch. Most Mi Band fitness trackers and Amazfit watches are designed for the Mi Fit app (now renamed Zepp), which is stable and broadly functional. However, new watch models such as the Mi Watch Lite or Color may require the installation of the Mi Wear app or even Xiaomi Wear.
Download programs should be exclusively from official sources: Google Play store or proven repository GetApps, preinstalled on Redmi 8. APK-files from third-party sites can lead to leakage of personal health data or incorrect notifications. After installing the application, you need to register or log into your Mi Account, since data synchronization is tied to this cloud service.
⚠️ Note: Do not try to connect the watch directly through the standard Bluetooth menu in the Android settings. This will create a “phantom” connection that will block work in the Mi Fit application.
When you first run the app, you'll ask for a number of permissions. To work properly with Redmi 8, you'll need to agree to access to contacts, call log, SMS, location, and physical activity. Without those permissions, your smartwatch's functionality will be stripped away: you won't be able to see the caller's name or track the route of your jog.
The process of pairing through the Mi Fit application
Launch the installed application and go to the Profile tab in the lower right corner of the interface. Click Add device and select a category corresponding to your gadget (for example, "Clock" or "Tracker"). At this point, the system will start scanning the surrounding space for available Bluetooth signals.
Make sure the watch is in pairing mode (usually it is the start screen with the QR-As soon as your model name appears on the list, click on it. The Redmi 8 screen will ask for confirmation of pairing, and the clock will ask for a digital code or confirmation button.
What if the search does not find the clock?
Once the connection is successful, the timing process will begin, and perhaps the firmware update of the watch will begin, so don't interrupt the process and keep the devices nearby, and the firmware can be updated in the background, improving the accuracy of the pulse sensors and the stability of the connection.
| Parameter | Mi Fit (Zepp) | Mi Wear | Direct connection |
|---|---|---|---|
| Supported devices | Mi Band, Amazfit, old models | Mi Watch, Color Watch | Audio/basic profile only |
| Synchronization of notifications | Complete. | Complete. | Absent. |
| Activity history | It's stored in the cloud. | It's stored in the cloud. | It doesn't last. |
| Setting up dials | A huge choice. | Limited choice | Impossible. |
Configuring MIUI Permits and Energy Saving
The MIUI shell installed on Redmi 8 is known for its aggressive memory management system, which can "kill" the background processes of the Mi Fit application to save battery power. To ensure that the watch does not break the connection every few hours, you need to manually adjust the priority of the application. Go to Settings → Applications → All applications, find Mi Fit and select Autostart, activating it.
Next, in the same menu, find the charge saving section and set the No Limits value. This is a critical step, since the standard mode can block the Bluetooth scanner when the phone screen is off. It is also recommended to fix the application in the list of recent tasks by pulling the application card down or pressing the lock so that the system does not unload it from RAM.
💡
For maximum stability of the Redmi 8 smartwatch, create a separate “No Limits” profile in the battery settings and assign it to the Mi Fit app. This ensures that the system never stops syncing data.
Make sure to check permissions in the Other Permits section. Make sure all switches, especially those related to Bluetooth, location and notifications, are active. If you plan to use the watch for payment (Mi Pay), additional permissions will also be required to make sure that you are not using the watch for payment. NFC-If you have it in your watch model.
Solving Typical Connection Problems
Even if you follow all the instructions, there can be situations when Redmi 8 stops "seeing" the watch or stops transmitting notifications. Often the problem lies in a crowded Bluetooth cache. Go to Settings → Apps → Show all the apps, click on three points in the corner, select System Processes, find Bluetooth and clear its data.
Another common cause of failure is Bluetooth version conflict. If you've previously connected many devices, the list may be overflowing. Remove any old gadgets you don't use from the list of connected devices. Also check if the watch is on "Do Not Disturb" or "Flight Mode" which blocks data transmission.
In some cases, a full network reset on your smartphone helps. Go to Settings → Advanced Settings → Recover and Reset → Reset Wi-Fi, mobile network and Bluetooth. Note that this action will remove saved passwords from Wi-Fi networks, but often resolves complex driver software conflicts.
Set up notifications and health features
Once you've successfully connected, you need to fine-tune the notification filtering so that the watch doesn't vibrate for every empty occasion. In the Mi Fit app, go to your device profile and select Application Notifications, and you can choose in detail which apps will broadcast messages on your wrist: WhatsApp, Telegram, SMS or calls.
For accurate health monitoring, it is important to enter your anthropometric data correctly. In your profile, specify current weight, height and age. Calorie calculation and sleep phase analysis depend on these parameters. It is also recommended to enable Sleep and Stress Monitoring if your watch model supports these options, as they require periodic calibration.
⚠️ Attention: Wrist Raise to Turn on the Screen can significantly reduce the time of the watch. If autonomy is more important to you than convenience, turn off this option in the settings of the watch screen.
Remember to calibrate the pedometer periodically. Go a known distance (e.g., 100 meters on stadium markings) and compare the clock. If the error is large, some advanced models have manual step calibration in the profile settings.
