Xiaomi’s modern wearables have become an integral part of the digital lifestyle of millions of users. The Mi Watch, Redmi Watch and Amazfit range offer a wide range of functionality, but their full operation is impossible without a stable connection to a smartphone. Bluetooth is the bridge that transmits notifications, health data and allows you to control music right from the wrist.
However, often users are faced with a situation where the watch is on but can not see the phone or vice versa. the inclusion of a wireless module may not be obvious, especially given the differences in the firmware of the Lite, Color and Global models. In this article, we will discuss in detail all the ways to activate communication, configure pairing and solve typical errors so that you can enjoy the full capabilities of your gadget.
The basics of the wireless module in the Xiaomi watch
Before you go into manipulating the menu, it’s important to understand exactly how synchronization works in the Xiaomi ecosystem. Unlike conventional Bluetooth headsets, smartwatches use a special data protocol that requires not only the radio module to be turned on, but also authorization through a proprietary application. Without this step, the clock will remain in standby mode, even if the settings say “Connected”.
There are two main scenarios: initial setup of the new device and reconnecting after a failure or battery discharge. In the first case, the module is often in Pairing Mode by default immediately after being removed from the box or reset. In the second case, manual activation through the operating system interface of the watch, whether it is Wear OS or proprietary MIUI for Watch, may be required.
⚠️ Warning: If you’re trying to connect your watch to a new phone, remember to untie it from the old device in the app first, otherwise there will be a profile conflict and the connection won’t be established.
Technically, the process is as follows: the watch generates a unique identifier that must be read by the smartphone. Successful data transfer requires both devices to have GPS activated (on Android) and allow geolocation access for the companion app. This is a security requirement of the Android operating system that is often ignored by users, leading to search errors.
Why does Bluetooth on a watch drain your battery?
Constant network search or trying to connect to a lost device can land the battery in a few hours. If you do not plan to use the watch right now, it is better to turn off the module in the settings or turn on the flight mode.> Turning on Bluetooth through the watch interface The most obvious, but not always available way is to control directly from the screen of the gadget. The interface of the Xiaomi Watch allows you to quickly toggles (switch) basic functions. However, it is worth noting that in some models, such as the Redmi Watch Lite, the ability to completely turn off Bluetooth through the menu is limited by developers to save energy, and the module is activated automatically when you try to synchronize the screen with the button and open the button. Pressing it changes the status of the module. If the icon is green or blue, the module is active. If it's gray, it's off. 📱 Swipe down: Open the Quick Settings Control Center on the Watch Screen. 🔍 Icon Search: Find the Bluetooth icon (you may need to swipe left or right if there are many icons). 👆 Activation: Click on the icon to change its state to "Included". ✅ Check: Make sure the icon is colored instead of gray. - In more advanced Wear-based models OS The path may be different. You go to the full app menu, select Settings, then find the Connection or Network and the Internet, and inside that section, the Bluetooth switch must be activated. Remember that after restarting the hours, the settings may reset and the procedure will have to be repeated. ☑️ Check before turning on Battery charge higher 20%The screen of the clock is unlocked Smartphone is nearby (to) 5 Meters on the phone Bluetooth enabled: 0 / 4 The main method of managing the Xiaomi and Amazfit watches is specialized applications. For new models, the Mi Fitness app (formerly Xiaomi Wear) is used, and for older or specific lines, Zepp is used. It is through these programs that the device is first "binded" and automatically turns on Bluetooth on the watch if it has been turned off. After logging in, you need to press the add-on button (usually a plus in the corner of the screen or the Profile tab. At that point, the watch may have a request to confirm pairing with or without code, and it's important not to confuse apps, for example, the Mi Watch Lite runs over Mi Fitness, while the Amazfit Bip requires Zepp. Trying to connect the device through the wrong app will cause the clock to be found, but data synchronization will not occur. The table below shows the matching of models and applications: Model of watches Recommended application Alternative application Mi Watch/Mi Watch Lite Mi Fitness connection features - Requires Mi Redmi Watch account 2 / 3 Mi Fitness - Fast pairing of Amazfit GTS / GTR Zepp - Needs a Zepp Mi Band account (all versions) Mi Fitness / Zepp Notify & Fitness Depends on the firmware version If the automatic search does not give results, try manually clicking the "Device Search" button several times. Sometimes the Bluetooth module on your smartphone falls asleep to save power, and you need to re-scan it. Make sure the application has all the necessary permissions, especially access to geolocation and files. Problem solving: the watch does not see the phone The situation when Xiaomi watches do not detect the smartphone or refuse to connect is one of the most common. Often the reason lies not in the hardware failure, but in the software conflict or “hung” state of the Bluetooth stack. The first thing you need to do is to completely reboot both devices: both the watch and smartphone. Another common reason is the presence of the old interface profile in the phone memory. If you previously connected this watch, the system could have stored a similar encryption. You need to go to the Bluetooth settings of the smartphone, find the device in the list of "My devices" or "Adjoined devices" and click Forget the device or Untie. 🔄 Reboot: Run a full (reboot) smartphone and watch. 🗑️ Cache Clearing: In your phone's Bluetooth settings, delete all old watch records. 📡 Visibility Check: Make sure the phone is visible to other devices (Visibility Mode). 📶 Distance: Bring the watch as close to the phone as possible. 10-20 It is also worth checking whether the antivirus or system energy saving device blocks the operation of the Bluetooth module, MIUI Aggressive battery optimization can kill the background process of finding devices. Add the Mi Fitness or Zepp app to the exclusion list and allow auto-run. ⚠️ Warning: When you reset your watch, all pairing data is deleted, and then the watch will be seen as a new device, and the old connection in the phone will become invalid. iPhone users can also enjoy Xiaomi watches, but the setup process has its own nuances associated with the closedness of the iOS operating system. You install the app first, and then you search for the watch, and trying to connect the device directly through your iPhone's Bluetooth settings often leads to an error. In iOS, the Bluetooth module runs in the background constantly if turned on, but for the stable operation of the clock, you need to allow the application to access Bluetooth and Locations (Always or When used). Without this notification, you may not come, and the pedometer will not sync. Also on the iPhone, you need to enable push notifications for the companion app itself. If pairing does not occur, try the following sequence: turn off Bluetooth completely in the iPhone settings (not in the control center, but in the settings), then turn it on again. Then, launch Mi Fitness or Zepp and start searching. Sometimes it helps to temporarily shut down your cellular network (flight mode) so that the phone focuses only on Bluetooth search. 💡On iPhone, when you request permission to use Bluetooth for the application, be sure to click "Allow", otherwise the watch will not be able to transmit pulse data and notifications. Reset Bluetooth settings and reboot module When standard methods do not help, you have to resort to more radical measures. Resetting the phone's network settings or completely resetting the clock to factory settings often solves the "invisible" module problem. However, before that, you should try a less destructive method - restarting the Bluetooth service. On Android, you can do this by turning on the flight mode for 10-15 seconds, and then turning it off. This forcibly reconnects all the radio modules. On the Xiaomi watch, you can find the "Reboot" option in the system settings menu. If the problem is of a software nature inside the watch module itself, such a reboot can clear the temporary driver errors. In extreme cases, if it is done by reconnecting to the device, if it is partially reconnected through the computer, if it can be used for switching on the device, if it, if it is able to switch on the computer, or if it is partially reconnected to switch on the device, if it is able to switch on the device, if it is able to switch on the computer. But most often, the problem is solved by simply removing the device from the app and re-associating it as a new gadget. What if the watch says "Pair failed?" This message means that the security keys did not match. Solution: remove the device from the phone's Bluetooth list, delete the account in the application (or untie the device), reboot the clock through the "Reset" menu and start the process again, making sure that the phone is nearby. Can you connect the clock to two phones at the same time? Officially, most Xiaomi Watch models do not support multi-connect (s simultaneously with two phones, they can actively remember several devices, but only need to switch off the first time). Check the battery settings on your phone for the companion app, and check if the watch is on Do Not Disturb or Sleep mode, which may limit the module's background activity. Does the Bluetooth enabled affect the clock's charging? Yes, constantly searching the network or transmitting large amounts of data (for example, updating the dial) consumes a charge (BLE) consumption is minimal and does not exceed 10-15% Does the Internet need to be turned on Bluetooth on the clock? No, the Bluetooth module itself does not need Internet. It is only necessary at the stage of initial registration of the device in the application and for synchronizing data (weather, maps) after connecting. 💡The key to a successful connection is the cleanliness of your profiles. Always delete old watch entries in your phone's Bluetooth menu before you try to pair them again.
