Xiaomi’s modern wearables have become the standard of affordable electronics, allowing you to track activity, heart rate and sleep without unnecessary costs. However, the process of initial pairing often raises questions among owners of Android smartphones, especially given the constant changes in the security policy of the operating system. Incorrect settings can lead to data loss or lack of notifications, which reduces the functionality of the device to zero.
Unlike simply turning on Bluetooth, full integration requires installing specialized software and properly configuring access rights. In this article, we will detail the algorithm of actions that are guaranteed to work for current models such as Mi Band 8, Mi Band 7 and earlier, you will learn about the intricacies of background services and how to fix typical connection errors.
Before you go into technical steps, make sure your device is ready to go. Charge the tracker at least 20-30%, as the process of initial synchronization and updating the firmware consumes a significant amount of energy. Also check that your smartphone is enabled Bluetooth and GPS (geolocation), because without them, finding the device is impossible.
Preparation of the smartphone and choice of application
The first and most critical step is choosing the right software. Mi Fit has long been the main synchronization application, but Xiaomi is actively migrating users to the new Mi Fitness platform (formerly known as Zepp Life in some regions, but now it is a separate application).
Owners of Xiaomi, Redmi and POCO smartphones should be especially careful: the system may already be pre-installed the application, but its versions are often irrelevant, it is recommended to remove old versions of programs for wearable devices and download a fresh distribution from the official Google Play store or GetApps. This will eliminate conflicts of versions of communication protocols.
⚠️ Note: Do not try to connect the bracelet through the standard Bluetooth menu in Android settings. Direct pairing without the application will lead to error or unstable operation, as the device requires specific authorization.
Once you install the app, you need to register for Mi Account or log in through an existing one, which is a mandatory requirement for cloud storage of training history and settings. Without authorization, the functionality of the gadget will be severely limited, and data synchronization will not be possible.
💡
If you have an old Mi Account that was created a few years ago, when you log in to the new Mi Fitness app, the system may offer migrate data.
The process of pairing devices
Launch the Mi Fitness app installed and go to the Device tab. Click on the Add New Gadget button, usually marked with a plus icon or a device add, at which point the system will start scanning the surrounding space for available Bluetooth Low Energy signals.
Put the fitness bracelet next to your smartphone, and if the tracker is new, it automatically goes into pairing mode, and it appears on the screen. QR-code or wait animation: If the device has been previously used, you may need to reset to factory settings via the menu of the bracelet itself (Settings for the bracelet) → Reset).
When your tracker name appears on the list of found devices (e.g. Mi Smart Band 8), click on it. The same confirmation codes should appear on your smartphone screen and on your bracelet display. Check them and click on Confirm or Link on both devices.
☑️ Checklist of successful connection
It can take anywhere from 30 seconds to a few minutes, and don't step far away from your smartphone and lock the screen, because the system may request additional permissions, and once you've successfully communicated, you'll automatically synchronize your time and basic settings.
Setup of permits and background work
The most common problem for Android owners is the lack of notifications and communication breaks. The operating system aggressively optimizes battery consumption by forcibly closing applications that it believes are not actively used. For Mi Fitness to work correctly, it needs to be granted extended rights.
Go to your smartphone settings, find the Apps section, and select Mi Fitness. You need to manually enable all the permissions you request: access to contacts, call log, SMS, location, and of course Bluetooth. Without geolocation permission, scanning devices often doesn't work.
Pay special attention to setting up energy saving. Go to the Battery or Advanced Settings section inside the app menu and select No restrictions mode. It is also recommended to enable autostart and display on top of other windows, which will allow the application to constantly maintain a connection to the bracelet.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Auto-start | Included. | The app runs with the phone. |
| Battery limitation | No restrictions. | The system does not “kill” the synchronization process. |
| Bluetooth resolution | Allowed always | Stable data exchange in the background |
| Access to contacts | Permission. | Displaying the names of callers on the screen of the bracelet |
💡
Without setting up the “No Limits” mode for the battery, Android is guaranteed to break the connection to the bracelet 15-30 minutes after turning off the smartphone screen.
Resolving Bluetooth and Visibility Problems
Sometimes, a smartphone simply doesn’t see the bracelet despite trying. In these cases, the problem is often the cache of Bluetooth services or connection conflict. Try clearing the cache of the Bluetooth module itself in the Android settings. Go to Settings → Applications → System Processes → Bluetooth → Memory → Clear the cache.
It's also worth checking if the bracelet is connected to another phone. Xiaomi's smart trackers can only store communication with one active device. If you've previously used the bracelet with another phone, be sure to remove it from the paired device list in the old gadget's Bluetooth menu and perform a reset.
In rare cases, switching Bluetooth versions helps. Go to the engineering menu (code ##6484## for Xiaomi phones) and check the Bluetooth tests, but this is an extreme measure. Most often, rebooting both devices, both the smartphone and the bracelet, is enough.
Hidden debugging teams
Update of firmware and calibration
Once successfully connected, the app will prompt you to update the bracelet software. Never ignore this update. New firmware versions fix sensor errors, improve pedometer accuracy, and add support for new features such as displaying emojis or new dials.
The upgrade process requires a stable connection. Put your phone and bracelet next to you, make sure you have a good battery charge, and don't leave the application until the process is complete.Bringing the boot can cause the device to "brick" even though current models have protection against this.
After the update, you should calibrate it, walk a known distance (e.g. 100 meters) and compare the data on the bracelet and in the application. If the error is large, you can manually set the step length in the profile settings, which will greatly improve the accuracy of the path computation.
