Modern wearables from Xiaomi and Redmi have become an integral part of the smart home ecosystem, offering users tracking health, notifications and activity. However, despite the common platform, initial configuration and pairing of devices sometimes cause difficulties even for experienced owners of this brand of equipment.
Redmi device owners often face aggressive battery optimization that can disrupt background services needed to maintain a stable connection with wearable electronics. In this article, we will detail the algorithm that is guaranteed to help you synchronize data, learn about the nuances of working with Mi Fitness and Zepp Life, as well as how to avoid common errors in the first run.
Successful connectivity is not just a flashing Bluetooth icon, it's full service integration. It's critical to use the current version of the Mi Fitness app for new watches, because older versions of Zepp Life may not support encryption protocols. Let's move from theory to practice and set your device up correctly the first time.
Preparatory stage: compatibility checks and updates
Before you start the pairing procedure, you need to make sure that your Redmi smartphone meets the minimum technical requirements.Most modern watches work with Android version 6.0 and higher, but for full functionality, including installing widgets and dials, it is recommended to have Android 10 or later. Check the OS version in the Settings → About phone section.
The second important step is to update system components. Often, connection problems arise from outdated Bluetooth drivers or Google Play services. Go to the Google Play Store, find updates for all applications and make sure that Google Play services are also relevant. Without this, sync can be unstable.
It's also worth checking the charge of both devices. Low charge can put the watch into power saving mode, hiding it from the search of the smartphone. Make sure that the watch is charged more than 20% of the battery and the phone has enough power to conduct the adjustment.
☑️ Checklist before connection
Choosing the right app: Mi Fitness or Zepp Life
One of the most common reasons for confusion is the choice of inappropriate software: Xiaomi has in recent years divided its product lines between its two main applications. New models such as the Redmi Watch 3, Watch S1/S3 and next-generation fitness bracelets are designed to feature Mi Fitness (formerly known as Xiaomi Wear).
Older models, including the popular Mi Band 4, 5, 6 and early-series Amazfit watches, have traditionally been controlled through the Zepp Life app (formerly Mi Fit.Attempting to connect a new device through an old app or vice versa often results in a search error or inability to complete the setup.
How do you know exactly what application you need?
Download applications should be exclusively from official sources: Google Play Market or App Store. APK-files from third-party resources can lead to data leakage or incorrect notifications. After installation, be sure to provide the application with all the permissions requested.
Step-by-step instructions for pairing devices
The binding process starts with the Bluetooth on your smartphone. Open the app you selected in the previous step (like Mi Fitness) and log in to your Xiaomi Account. This is a prerequisite for saving statistics and setting up profiles.
On the app's home screen, click the add-on button, usually a plus icon or a device button at the bottom of the screen, and the system will start scanning the gadgets, at which point a request to pair with a confirmation code may appear on the watch screen — check the numbers and click Confirm.
If the automatic search didn't work, try manual mode. In the list of available devices, find a model of your watch. The process of installing the necessary components and synchronizing time can take from 30 seconds to 2 minutes. Do not turn off the smartphone screen during this process.
Configure permissions and optimize the battery on Redmi
Redmi smartphones with a MIUI shell or HyperOS are known for their strict energy saving system. By default, the system can "kill" the background process of the watch application, which leads to a connection break and no notifications. To avoid this, you need to perform a special setup.
Go to Settings → Apps → All apps. Go to Mi Fitness or Zepp Life. Go to Battery and select No Restrictions mode. This will prevent the system from forcibly closing the application. Also enable auto-start for this service.
⚠️ Warning: Without setting “No Limits” you risk losing your day’s step history and stopping receiving notifications of calls and messages, even if the clock is formally connected.
In addition, it is recommended to fix the application in memory. Open the list of running applications (multitasking menu), find the window of the application for the clock and pull it down (or press the lock, depending on the version of MIUI) to lock it, this will provide priority access to system resources.
Solving Notification and Synchronization Problems
Users often complain that the watch is connected, but notifications from Telegram, WhatsApp or Viber do not come. To correct this situation, you need to manually activate each application. In the device management menu, find the "Application Notifications" section and turn on the toggles opposite the desired messengers.
If notifications never show up, check the system settings for notifications on the smartphone itself. Make sure that the Mi Fitness/Zepp Life app allows notifications to be displayed on the lock screen in Android settings. Without that permission, the watch will not be physically able to read the information.
Problems with synchronizing health data (pulse, sleep) are often solved by simply restarting both devices: Turn off the clock through the menu, restart the phone, and then reopen the application for forced synchronization. If the data is not updated for more than an hour, try removing the device from the application and adding it again.
| Problem. | Possible cause | Decision |
|---|---|---|
| Clock not found | Bluetooth is enabled but GPS is turned off | Enable geolocation in the notification curtain |
| No notifications. | Blocking background activity | Put “No Limits” in the Battery |
| Resetting connection | An outdated version of the app | Update Mi Fitness/Zepp Life to Play Market |
| Wrong time. | Synchronization error at start-up | Forced synchronization in the device profile |
Advanced settings and interface personalization
Once the basic features have been successfully set up, personalization is worthwhile, with apps that allow you to set new dials, adjust the order of widgets and change the wrist lift settings. The Redmi Watch has a variety of third-party dials available in the Mi Fitness store.
Pay attention to your health monitoring settings. Smart heart rate saves battery life, but it can skip jumps. Sports is better at setting a 1-10 minute interval, and you can set up reminders about (sedentary lifestyle), which is good for office workers.
💡
Tip: For maximum autonomy, turn off the Always On Display function and reduce the brightness to 40-50%. This will extend the clock for 1-2 days without loss of readability.
Remember to update the firmware itself regularly. Notification of the new firmware version comes to the app. Updates often contain Bluetooth stack bug fixes and improve sensor accuracy. The process takes about 5-10 minutes, during which time the watch should be near the phone.
What if the clock is stuck and does not respond to touch?
Can I connect my watch to two phones at the same time?
Why does the app require access to contacts and microphone?
💡
The main guarantee of stable work is the correct setting of energy saving in the MIUI/HyperOS. Without background permission, a smart watch becomes a regular digital chronometer.
