The Chinese manufacturer’s modern wearables have long since ceased to be pedometers, becoming full-fledged extensions of your smartphone. The ability to quickly view incoming messages without taking your phone out of your pocket has become the standard of comfort for millions of users around the world. However, when it comes to the popular messenger, many owners of budget and mid-budget models face unexpected difficulties in initial synchronization.
The problem lies in the architecture of the Wear OS operating system and proprietary HyperOS or MIUI for Watch shells, which handle background processes differently. Unlike the Apple Watch, where integration is built into the system level, the Android and Xiaomi ecosystem requires manually configuring multiple settings to work consistently. Incorrect configuration often leads to notifications arriving late or not displayed at all, negating the functionality of the device.
In this article, we will take a look at the algorithm that will allow you to make the messenger work smoothly. We will look at both the software part and the power saving settings that often block the operation of applications. You will learn how to properly link devices and what hidden settings may be necessary to correctly display text messages and pictures.
Model Compatibility and System Requirements
Before you start setting up, you need to make sure that your wearable device is technically capable of supporting the full operation of the messenger or at least its notifications. Xiaomi’s smartwatch market is divided into two main categories: devices based on Wear. OS (For example, Xiaomi Watch 2, Watch 2 Pro and gadgets on a proprietary system RTOS (Redmi Watch, Mi Band, Xiaomi Watch S1 The type of operating system directly affects the functionality on Wear. OS You can install a full application, and RTOS Only notices are available.
Android on a conjugate smartphone is also important for advanced features. It is recommended to use versions of the operating system at least 8.0, since older versions may not correctly transfer data packets for wearable devices. In addition, the messenger application itself must be updated to the latest current version through the official Google Play store.
List of fully compatible models
It's important to understand the difference between "installing an app" and "setting up notifications." If you have an RTOS model, you won't find an instant messenger icon on the watch menu, but messages will come in the form of system fluffs. Wear OS models have full interactivity, including the ability to respond to messages with voice or keyboard.
- 📱 Xiaomi Watch 2 / 2 Pro: Full support for native app and voice input.
- ⌚ Redmi Watch 3 / 4: Only display notifications, answers are not possible.
- 💪 Mi Band 8 / 9: Basic display of the text of notifications without the possibility of interaction.
- 🔋 Xiaomi Watch S1 Active: Limited notification functionality due to system architecture.
💡
The key factor is the clock’s operating system: Wear OS allows you to install apps from the store, and RTOS only works with notifications from your smartphone.
Preparation of the smartphone and installation of the necessary components
The foundation of successful synchronization is the proper preparation of the main device - your smartphone. The first step will be to install or update the branded application Xiaomi Wear (for global versions of watches) or Mi Fitness (for new models and fitness trackers).
You need to check for all the components of the messenger itself. To work correctly on the watch, you often need not only the main application, but also additional service modules. Make sure that the phone has Google Play Services installed and they are updated, as they are responsible for push notifications in the Android ecosystem.
☑️ Preparation of the smartphone
Special attention should be paid to permissions. When you first run a watch app, the system will request access to contacts, microphone and notifications. Failure to do so at any of these points can result in the watch not being able to pull information out of the messenger. In modern versions of Android, permissions must be confirmed manually in the system settings menu.
It is also critical that the operating system versions on the watch and phone are compatible. Check the watch firmware updates through the Profile → Device Settings → Update. Outdated watch software may not support the new encryption protocols used by the messenger.
Basic synchronization with the Mi Fitness app
The pairing process is the starting point for any data transfer. Open the Mi Fitness app (or Xiaomi Wear) on your smartphone and go to Profile. Here you need to find Application Management or Notification Settings. The interface may vary slightly depending on the version of the application, but the logic remains the same.
In the list of available notification apps, find WhatsApp. By default, the switch is often in the "Off" position. Activate it. After that, the system can request confirmation of access to notification history, which is the standard Android security procedure for broadcasting text messages to the watch screen.
⚠️ Warning: If notifications don't come after switching on, try turning off Bluetooth on your phone, wait 10 seconds and turn on again.
For Wear-based models OS You need to open the Play Market store directly on your watch (or through your phone, selecting the installation device), find the WhatsApp app and click the Install button. QR-code similar to the WhatsApp Web login.
- 🔗 Open the Mi Fitness app on your smartphone.
- 🔔 Go to the Settings section → Notification of annexes.
- ✅ Find in the WhatsApp list and activate the slider.
- 📲 For Wear. OS: install the app directly from the store on the clock.
Configure energy saving and Android permissions
The most common cause of broken notifications is an aggressive energy saving policy embedded in the MIUI and HyperOS shell. The system seeks to extend the smartphone’s life by forcibly closing background processes, including services responsible for transmitting data to the clock. To avoid this, you need to create an exception for the messenger application and the wearable device service.
Go to Settings, select Apps → All Apps. Go to WhatsApp, then go to Activity Control (or Battery). Select No Limits mode. This action will prevent the system from "killing" the messenger process, even if you haven't opened it in a long time.
Path to settings:
Settings → Applications → All apps → WhatsApp → Activity control → No restrictionsThe same procedure must be repeated for the Mi Fitness (or Xiaomi Wear) application itself, which should have constant network and Bluetooth access, and in the Additional Permissions menu, make sure that Auto Run and Display in the background are included.
Remember that settings may reset after updating the system or the application itself. Periodic checking of these settings will help keep notifications running smoothly. If you use third-party launchers or memory cleaners, add the necessary applications to the whitelist.
💡
For maximum reliability, include (lock) in the list of running applications for Mi Fitness. This will prevent the application from accidentally closing when cleaning the memory.
Solving problems with display and delay of messages
Even when properly configured, users may encounter artifacts: messages arrive empty, 10-15 minutes late, or are displayed incorrectly (crackers instead of text). Often the problem lies in the settings of the messenger itself. Inside WhatsApp, go to Settings → Notifications and make sure that High Priority option is enabled (if available) and content is allowed to display on the locked screen.
Another reason for the delays could be Do Not Disturb or Sleep, activated on the watch. Check the dial: if there's a moon or bed icon, the notifications will only come to the phone, and the clock will only be recorded in history. Also check if the charge saving mode on the watch itself is on, which limits the frequency of synchronization.
| Problem. | Possible cause | Method of decision |
|---|---|---|
| Messages don't come. | Notification permission turned off | Enable in Mi Fitness and Android System |
| Delayed arrival | Aggressive energy conservation | Set "No Limitations" for background work |
| Text is not readable | Incompatibility of fonts or coding | Update the application and change the font in the system |
| No sound/vibro | Do Not Disturb on the clock | Turn off the silence mode in the curtain of the clock |
If the problem persists, try reconnecting the device. In the Mi Fitness app, select Delete the device, then forget the device in the phone's Bluetooth settings. Then pair again. This often helps to reset the data protocol errors.
Advanced Features: Answers and Multimedia
Wear OS watch owners have the unique ability to not only read but also respond to messages, and this requires access to a microphone and keyboard when using the watch settings in the Apps → WhatsApp section. Voice input is enabled through Google services, so a stable Internet connection is required.
For limited-function models (RTOS), only quick answers (pre-prepared phrases) are available. You can configure them in the Mi Fitness: Profile → Device settings → Quick answers. Here you can replace the standard "Yes", "No", "Occupied" with your own options, which will be displayed when you try to respond to a notification.
⚠️ Note: Sending images, voice messages and documents from a clock based RTOS (Redmi Watch, Mi Band is technically impossible due to operating system limitations, and is only available on full-fledged Wears. OS device.
Multimedia on Wear OS also has its own peculiarities: when you get a photo, it may not automatically load to save traffic, you need to tap the thumbnail to initiate the download, make sure that the watch is enabled data transfer over Wi-Fi or Bluetooth modem of the phone.
