Modern wearables have become an integral part of the smart home ecosystem, and integrating them properly with a smartphone is critical to obtaining accurate health data. Users often face difficulties in initial pairing, especially when it comes to specific Android operating system settings on Xiaomi brand devices.The process seems simple, but hidden power saving mechanisms can break the connection immediately after setting up.
In this article, we will take a look at the algorithm that ensures that data is synchronized between your phone and your wearable, and learn about the intricacies of Zepp Life and Mi Fitness, as well as how to set up the background of services, which will help you avoid situations where the watch stops receiving notifications or does not record steps.
Before you start to act, you need to make sure that both devices are charged and in close proximity to each other, the distance should not exceed one meter to ensure that the Bluetooth signal is as stable as possible, and ignoring this rule is the most common cause of errors when searching for a device.
Preparation of devices and preliminary diagnosis
The first step is to check the basic parameters of both gadgets. Make sure that the clock is on Bluetooth and they are in pairing mode (usually this is the start screen with a light-based light-up screen). QR-On the Xiaomi smartphone you need to activate geolocation (GPS), Modern versions of Android require location access to search BLE-device.
It is important to clear the list of previously paired devices in your phone's Bluetooth settings. If your watch has previously connected to another phone or was reset but is left in your smartphone's memory, this will cause an address conflict. Go to Bluetooth settings, find your watch name in the "Other Devices" or "Conjugated" list, click on the gear and select "Unpair" or "Forget device."
⚠️ Note: Do not try to connect the watch directly through the standard Bluetooth menu of Android settings. This will lead to pairing error or unstable work, as profile management should be carried out exclusively through the proprietary application.
Check the version of your phone’s operating system. For the correct operation of modern applications, Android 6.0 and higher is required, but for full functionality of Mi Fitness, it is better to use the current versions of the OS. Also make sure that the phone has the current Google Play Services service, which is necessary for maps and synchronizing profiles.
The next step is to choose the right software. Xiaomi's ecosystem uses two main applications, and the choice depends on the model of your watch. Old models (Mi Band 4, 5, 6, older versions of Amazfit) require the installation of Zepp Life (formerly Mi Fit). New devices such as the Mi Band 7/8, Mi Watch and most Amazfit watches are moving to the Mi Fitness platform (formerly WearOS or Zepp OS depending on the model).
Installation and configuration of the profile application
Software downloads should be done exclusively from official sources to avoid malicious code. Open a Google Play or App Store and search for the name of the application you want. After installation, take your time to open the program, you must first provide it with all the permissions you ask for.
When you first run it will request access to geolocation, contacts, microphone and storage. Denial of access to geolocation will make it impossible to find the watch, and lack of access to notifications will make it impossible to see messages on your wrist. In the MIUI system, permissions can be requested again every time you update the application, so be careful.
The Xiaomi and Amazfit ecosystem requires an account to be created, and the real data (date of birth, weight, height) is recommended, as it determines the correctness of calorie and pulse zones calculation, and an error in these parameters will lead to incorrect activity analysis algorithms.
💡
When registering for an account, choose the “Russia” or “Country of residence” region, not “China” if you do not use specific Chinese versions of devices, which will ensure the correct operation of the sync servers and the interface language.
After you log in, go to the Profile or Mine tab, and there's usually a "Add Device" or "plus" button at the top of the screen. Pressing this button will start scanning the surrounding space, and make sure the phone isn't in power-saving mode, which can limit the Bluetooth scanner.
The process of pairing and activation of the clock
When the app starts searching, your watch and the Connect button should appear on your smartphone screen. If the device is found but not connected, try rebooting Bluetooth on your phone. In rare cases, it helps to temporarily turn on flight mode and then turn on the communication modules.
When pairing a watch, you can have a numerical code or a confirmation request, you can check the numbers on your smartphone display and on your watch, and then you can click "Confirm" or "OK" on both devices, and this security mechanism prevents you from connecting to other devices in crowded places.
☑️ Checklist of successful pairing
If the automatic search does not give results, you can use the manual method through the QR-The clock (or box/in the instructions) often has a code. QR-In the application, select the option "Scan" QR-This is especially true for models that don't appear in the general list due to regional restrictions.
Once the connection is successful, the process of synchronizing time and updating the firmware of the watch will begin. Software updates are critical. New versions of the firmware fix connection errors and add support for new functions. Interrupting this process can cause the device to break, so make sure that the charge of the watch does not fall below 20%.
| Model clock | Recommended annex | Minimum version of OS | Features of connection |
|---|---|---|---|
| Mi Band 4 / 5 / 6 | Zepp Life | Android 6.0+ | Old Mi Account required |
| Mi Band 7 / 8 | Mi Fitness | Android 7.0+ | Entry into Mi Account is required |
| Amazfit GTS / GTR | Zepp | Android 7.0+ | Separate ecosystem |
| Mi Watch Lite | Mi Fitness | Android 6.0+ | Synchronization through Wi-Fi |
Critical MIUI settings for stable operation
Owners of Xiaomi, Redmi and POCO smartphones are facing an aggressive MIUI energy saving system that kills application background processes by default to save battery power. To keep the watch from switching off the phone every few hours, you need to manually change the settings for the companion app.
Go to Settings → Applications → All apps. Go to Zepp Life or Mi Fitness. Go to Battery (or Battery Consumption) and select No Limits. This will prevent the system from forcibly closing the application, which is necessary for instant notifications.
⚠️ Warning: Without setting "No Limits" you can not receive notifications about calls and messages until the application is manually launched. 10-14, Not a clock fault.
The second important option is autorun. In the same app settings menu, find Autostart and activate it. This will allow the app to start immediately after the phone is turned on without waiting for the user to act. It is also recommended to fix the application in memory: open the list of running applications (swipe from the bottom up and hold), find the application window and press the lock.
Additionally, check permissions in Settings → Apps → Permissions → Autostart. Make sure the switch opposite your fitness app is green. Some versions of MIUI also require you to turn on the display over other windows to properly operate alarm clocks and timers.
What to do if settings are reset after the MIUI update?
Setup of notifications and data synchronization
After you have set up the connection, you have to personalize it. In the app, go to the device profile and find the "Application Notifications" section, and you can choose which apps will duplicate messages per clock, and if you have too many sources, you can quickly drain the battery.
To correctly display the text of messages (especially Cyrillic), it is important that the settings of the system language and clocks were the same language, preferably Russian or English. Sometimes it helps to clear the cache of the application, if instead of text come characters or Krakozabras.
Health data syncs automatically when you open an app, but if the data isn't updated, check your privacy settings, and Google Fit or Apple Health (where the data is often exported) must allow data to be imported from Zepp or Mi Fitness, which will create a single database of your activity.
You should pay special attention to setting "Wrist Raise to Turn on the Screen." If this function is not working correctly (the screen does not light up or light up too often), try recalibrating it in the clock settings or changing the sensitivity. You can also adjust the schedule of this feature so that it does not bother you at night.
💡
Properly configuring notifications and excluding the application from the power consumption list is the key to ensuring that the watch will work as a full-fledged second screen of your smartphone, and not just as a pedometer.
Solving Common Connection Problems
Despite following all the instructions, there can be specific errors: If the watch sees the phone but doesn't connect, try changing the phone's Bluetooth settings to a simpler one, without special characters, which sometimes helps bypass the pairing protocol's software bugs.
In case the app says “Device is busy” or “Can’t connect”, perform a full reset to factory settings (usually via the Settings menu of the hours). → Reset or press a button. After reset, remove the device from the application and create a new profile again.
Long-range problems are often caused by physical obstacles or interference from other devices (Wi-Fi routers, microwaves).If the connection is lost at a distance of 2-3 meters, check if the watch is wearing a metal bracelet that can shield the antenna signal.
⚠️ Note: If the watch has stopped responding to any commands and is not turned on, set them on charging on the watch. 30-60 Deep discharge of lithium-polymer battery is a common cause of the "dead" state of the gadget after a long downtime.
For advanced users who are faced with incompatibility of Android versions, there is the possibility of using third-party utilities to emulate a Bluetooth address, but this requires root rights and can disrupt other system functions.
