The process of pairing wearable electronics with the Android ecosystem, especially those based on the MIUI and HyperOS shells, often raises questions among users, despite the seemingly simple procedure. Owners of Xiaomi and Redmi gadgets face aggressive optimization of the system’s power consumption, which can interrupt the background processes of smart watches, which leads to notifications not coming, health data is not stored, and communication is lost at the most inopportune moment.
To keep the device running, you need to perform a number of specific settings that go beyond standard Bluetooth device search. Proper synchronization of Amazfit requires not only the installation of the application, but also deep integration into the system settings of the smartphone. In this article, we will discuss in detail all the stages of connection, setting permissions and methods for eliminating common errors that are characteristic of the Chinese watch and phone bundle.
Ignoring some of the system limitations of MIUI can negate the functionality of the gadget, so it is important to approach the issue comprehensively, paying attention to every step, from downloading the right software to setting up auto-start, so that you can unlock the full potential of your activity tracker.
Preparing for the connection: the choice of the application and the account
The first and most critical step is choosing the right software. The Amazfit ecosystem has historically used the Zepp app (formerly known as Amazfit), but for new models and better integration with Xiaomi devices, the company is actively promoting the Mi Fitness platform. The choice depends on the model of your watch: older versions like the GTS 1/2, the first generation T-Rex work better with Zepp, while new lines require Mi Fitness.
When registering for an account, it is important to choose the right region. If your watch is purchased in China or has a specific firmware, the region in the app may not match the region of the Mi Account account on the phone. This often causes you to not log in. It is recommended to choose the region corresponding to your actual location or the one indicated in the instructions for a particular device.
Apps should be downloaded exclusively from official sources such as Google Play or AppGallery. Third-party modified versions may contain malicious code or work incorrectly with data encryption protocols. Make sure that your Xiaomi smartphone has an up-to-date version of the operating system, as older versions of Android may not support the necessary Bluetooth LE protocols in full.
- 📱 Install Mi Fitness or Zepp app depending on the watch model.
- 🌏 Select the registration region that matches the region of sale of the device.
- 🔐 Create a new account or log in through an existing profile Google/Apple.
- 🔄 Update your smartphone operating system to the latest available version.
⚠️ Note: When using the Mi Fitness app on Xiaomi phones, you may need to install an additional system plugin.
The process of primary pairing via Bluetooth
Don’t try to pair solely through the standard Bluetooth menu in Android settings. This is a common bug that leads to conflicts.Amazfit smartwatches require authorization through the interface of a specialized application to transfer encryption keys and customize profiles.If you connect them through the system menu first, the application may not see the device or work with errors.
Turn on Bluetooth on your smartphone and launch the selected app. Go to the add-on section of the device, usually located on the home screen or in the profile menu. The application will start scanning the surrounding space. At this point, the watch screen may request confirmation of pairing with or without the code — check the numbers and click the tick.
The initialization process can take anywhere from one to five minutes. This is the time when data is exchanged, time is set, time zones are synchronized and dials are loaded. Interrupting this process can cause the watch to remain in standby mode or display incorrect time. Keep the smartphone and the watch no more than 1 meter apart.
☑️ Checklist of primary connection
Once the connection is successful, the system will offer notifications and sensor access, which will form the basis for the tracker to work, and the stability of the connection will depend on how correctly the initial configuration files were transmitted.
Permissions and optimization of MIUI/HyperOS
MIUI and HyperOS shells are known for their rigid energy saving system, which by default limits the background activity of applications. For smartwatches, this is critical: if the system kills the process of the Zepp or Mi Fitness application, you will stop receiving notifications and pulse data will be intermittent. You need to manually change the settings for a particular application.
Go to Settings → Apps → All apps and find your watch app. In Battery or Energy, select No Limits mode. This will prevent the system from forcibly closing the app even if it is not in use for a long time. Also make sure that autorun and display on top of other windows are enabled.
Special attention should be paid to access rights. Applications require access to location (for the purpose of accessing the application). GPS-With no permissions, the clock will be severely restricted. In modern Android versions, it is also important to allow access to nearby devices).
- 🔋 Set the energy saving mode for the watch to the value "Without restrictions".
- 🚀 Enable auto-start the application in Task Manager.
- 📍 Provide access to geolocation in "Always" mode for tracking training.
- 📞 Allow access to contacts and call logs to display notifications.
Why does MIUI kill background processes?
After making all the changes, it is recommended to restart the smartphone, which ensures that all new energy saving policies take effect and background services start correctly.
Synchronizing Health Data and Google Fit
One of the main purposes of using a smartwatch is to track physical activity, but the data collected by the watch should be integrated into a single ecosystem. The Amazfit and Xiaomi Wear apps allow data to be synchronized with Google Fit, Apple Health and Strava platforms, which is especially important for users who use third-party services to analyze workouts.
To set up sync with Google Fit, go to the watch app profile, select Add Accounts or Linked Devices. Sign in to your Google account and provide the necessary permissions, and then the steps, pulse, sleep and workouts will be automatically transmitted to the Google shared database.
It is important to understand the difference between one-way and two-way synchronization. Most often, data comes only from the clock in Google Fit. Back-to-back synchronization (for example, adding a workout to Google Fit manually and waiting for it to appear on the clock) is not supported by all models and applications. Two-way synchronization is possible only when using the native Mi Fitness application on Xiaomi smartphones with Google services installed.
| Parameter | Google Fit | Apple Health | Strava | Local storage |
|---|---|---|---|---|
| Transfer of steps | Yes. | Yes. | No. | Yes. |
| Pulse transmission | Yes. | Yes. | Only during training. | Yes. |
| Sleep data | Yes. | Yes. | No. | Yes. |
| GPS tracks | Yes. | Yes. | Yes. | Yes. |
Regularly checking your linked accounts helps you avoid data loss, and if you notice that your data has stopped updating in Google Fit, try to break the connection and log in again.
Update of the firmware of watches and dials
Manufacturers regularly release firmware updates that fix bugs, improve sensor accuracy, and add new features. Ignoring updates can lead to unstable device performance. Check for updates can be done in the device profile within the application.
The upgrade process requires a stable connection and battery charge of at least 30-40%. If the clock charge drops to zero during the upgrade (OTA Update), the device may go into recovery mode or become inoperable. It is recommended to put the watch on charge before the procedure, even if the indicator shows a high charge level.
Dials also require periodic updates, especially if you use complex animated faces. They can take up a significant space in the clock's memory, which slows down the interface. Remove unused dials through the app to make room for system files.
⚠️ Warning: During firmware updates, it is strictly forbidden to close the application on your smartphone or take your phone to sleep.
If the update is stuck at a certain percentage, don't panic. In some cases, rebooting the clock with a button helps, but most often the process resumes itself after reconnecting to the application.
Removing common connection problems
Even when set up correctly, there can be failures. The most common problem is that the watch doesn't find the phone or constantly loses connection. First of all, check if the phone is on Do Not Disturb or Flight mode, which can block the Bluetooth module, and cleaning the cache of the watch application also helps.
If the watch stops syncing, try resetting the Bluetooth stack completely. Remove the device from the Bluetooth conjugated list, delete the account in the app itself (not always necessary, but effectively), and pair it again. Sometimes you need to reset the watch itself to factory settings via the Settings → System → Reset menu.
Notification problems are often solved by checking specific permissions for each application (WhatsApp, Telegram, Viber). The watch app should have a separate list of apps for which notifications are allowed to be output. Make sure that the switches opposite the right messengers are active.
- 🔄 Complete reset of Bluetooth connection (forget device).
- 🗑️ Clear the cache and data of the intermediary application (Zepp/Mi Fitness).
- 📵 Check if the antivirus or the Optimizer is blocking Bluetooth.
- 🔌 Reboot both devices at the same time.
💡
If the watch is constantly losing touch, try turning off the Smart Screen Wake feature on your phone, which in some versions of MIUI conflicts with the constant search for Bluetooth devices.
In rare cases, the problem can be hardware. If none of the software methods work, it is worth checking the clock with another smartphone. If there is also unstable communication, the Bluetooth module in the watch may have failed.
💡
90% of synchronization problems are solved by properly configuring the power saving in MIUI and re-pairing the old device from the phone’s memory.
