Fitness bracelet Xiaomi does not connect to the phone: step-by-step solution

The situation when a new or familiar fitness tracker suddenly stops seeing a smartphone, familiar to many users of the Xiaomi ecosystem, is a natural irritation, especially if you are used to monitoring your sleep and activity daily.

Before you bring a device to the service, you need to eliminate software errors that are easy to fix yourself. 90% of the time, it helps to reboot communication modules or reinstall a companion application. It is critical to understand that older versions of Mi Fit and Zepp Life applications no longer support current models of bracelets, such as the Mi Band 7 and 8, requiring a transition to the Mi Fitness platform.

In this article, we will discuss in detail the algorithm of actions that will help restore the connection, we will look at the nuances of the Android and iOS operating systems, since the approaches to configuring access rights and permissions on these platforms differ significantly.

Primary diagnostics of Bluetooth connection

The first step should always be to check the status of wireless modules. Often Bluetooth on a smartphone is not working correctly due to accumulated cache of errors or temporary freeze of the driver. Simply turning off and turning on the function in the notification curtain does not always clear the error buffer.

You need to do a deeper reboot of the communication stack, and to do that, go to your phone's settings, find the Bluetooth partition and force it to stop, and then start it again. If you're using Android, resetting your network settings will be helpful, but this action will delete the stored Wi-Fi passwords.

• 📱 Make sure the bracelet does not have a Do Not Disturb or Sleep mode that can block device search.
• 🔋 Check the tracker’s charge level – at a critically low battery level (less than 10%), the Bluetooth module can go into energy-saving mode and become invisible.
• 📶 Make sure that the smartphone is not in flight mode and the distance between the devices does not exceed 5-10 meters.

⚠️ Note: If your bracelet is already listed on the phone’s paired devices (such as the Mi Band 4 or 5) but it’s not connecting, be sure to click “Forget the device” or “Cancel pairing” before trying again.

Sometimes third-party apps can intercept control of the Bluetooth adapter, interfering with the normal synchronization of the fitness tracker.Close all background programs, including navigators and messengers, to free up the system resources for a stable connection.

Choosing the right app: Mi Fitness or Zepp Life

One of the most common causes of connectivity problems is software confusion, with Xiaomi gradually migrating users from the Zepp Life platform (formerly Mi Fit) to the new Mi Fitness app (formerly Zepp), which older bracelet models may require one app and newer ones may require another.

For current devices such as the Mi Smart Band 7, 8 and their Pro versions, as well as for the Redmi Watch, it is recommended to use the Mi Fitness. Trying to connect them through the outdated Zepp Life often leads to sync errors or the complete absence of the device in the search list.

If you upgraded to the new version of the bracelet but stayed in the old app, the data may stop coming in, which requires exporting your activity history and re-associating the device through the new software, and the data migration process is usually automated if you use the same Mi Account.

• 📲 For Mi Band 6 and newer models, it is preferable to use the Mi Fitness platform for full functionality.
• ⚙️ Older models (Band 3, 4, 5) are more stable in the Zepp Life environment, although they are supported in the new program.
• 🔄 When switching between apps, remember to untie the device in the old profile before connecting in the new one.

⚠️ Warning: Simultaneous installation of both apps (Mi Fitness and Zepp Life) on the same phone can cause conflicts of background services, because of which neither of them will be able to correctly connect to the tracker.

Make sure that the version of your smartphone’s operating system meets the minimum requirements of the app. iOS is usually at least 12.0, and Android is at least 6.0. On older OSes, newer versions of apps may not work properly.

Configure access rights and permissions on Android

Modern versions of Android (starting with the 10th and especially 11, 12, 13, 14) have strict privacy policies. To operate a fitness bracelet, an application needs access not only to Bluetooth, but also to geolocation. Without GPS enabled, scanning devices is often impossible due to the peculiarities of the BLE (Bluetooth Low Energy) protocol.

Go to your phone's settings, select "Apps," search for Mi Fitness or Zepp Life, and go to "Permissions," where you manually activate location access by selecting "Allow Always" or "Allow Only When Used," and it's also critical to give permission to work in the background.

Settings → Applications → Mi Fitness → Permissions → Location → Allow

Another important setting is to remove the application from power saving mode. The system can kill the synchronization process, considering it to be energy intensive. Find the "No Limits" or "Autostart" option for your fitness application in the battery settings.

• 📍 Turn on geolocation (GPS) on the phone before searching for the device.
• 🔋 Turn off the power saving mode for the companion app.
• 📂 Allow access to device memory to save logs and firmware updates.

On Xiaomi smartphones with MIUI or HyperOS shells, there is an additional layer of protection: go to the battery settings, find the app and set a "No Limits" strategy, which will prevent sync services from being forced to stop.

Features of connection on iPhone (iOS)

iPhone users face connection problems less often, but they have their own specifics: In iOS, Bluetooth device management is more centralized, and the tracker often requires confirmation in the system menu, not just in the app, to work.

If the bracelet doesn't connect, check your privacy settings. Go to Settings → Privacy & Security → Location and make sure that the Mi Fitness or Zepp Life app has an "Always" switch. Without this, synchronizing route and step data is impossible.

It's also worth checking if the bracelet is locked in Bluetooth system settings. Sometimes iOS remembers the device as "unsupported" or "accessories" if the previous pairing was wrong, so you go to Bluetooth system settings, find the device and click "Forget this device."

⚠️ Note: On iOS 16 and later, a system window may appear when you connect to request pairing. If you accidentally click Cancel, the request may not appear for a long time.

It’s important to make sure that the phone doesn’t activate features that block background activity, such as Low Power Mode, in which iOS restricts background updates, leading to breaks in the bracelet connection.

Resetting and reconnecting the device

If the software settings are checked but the bracelet is still not visible, you need to reset the tracker itself.Most Mi Band models do not have a physical button, so the reset is done via the menu on the screen or forced reboot.

For touchscreen models (Mi Band 6, 7, 8), go to the menu, find System or Settings and select Reset or Factory Settings, which will return the device to a state ready for initial pairing.

Once reset, the bracelet will go into search mode, at which point it becomes visible to other devices, and it is important not to delay the connection, since visibility can be limited in time to save energy.

If a reset over the menu is not possible, try putting the bracelet on charge. Connecting to a power source often causes the device to automatically reboot, which can eliminate temporary software failures.

Compatibility table and typical errors

Below is a summary table that will help you quickly identify the problem based on your device model and observed behavior.

Note that for older models, using the latest Mi Fitness app may not be feasible, as the functionality may be cut down.

If the table shows an authorization error, it is often associated with choosing the wrong server region when you log in to your account. Make sure the region in the application matches the region specified when you register for your Mi Account.

💡

Try connecting the bracelet to another person’s phone (a friend or relative) and if the connection is successful, the problem is precisely with your smartphone settings, not with the hardware bracelet.

Update firmware and firmware

Often the cause of the instability is an outdated version of the firmware on the bracelet itself. Manufacturers regularly release updates to correct Bluetooth stack errors. If the bracelet connects but immediately shuts down, try to initiate the update manually.

In the app, go to the device profile and click "Update Check." The process can take from 5 to 15 minutes, at which time the bracelet screen may go out and turn on - this is normal, you can not interrupt the process.

If the update hangs on a certain percentage (e.g., 90%), don't panic. Leave your phone and bracelet next to you, connected to the charge, for 20-30 minutes. Often the process ends in the background.

• 📶 Make sure your phone is connected to a stable Wi-Fi network to download the service pack.
• 🔋 The charge of the bracelet before the update must be at least 50%.
• 📱 Do not open other heavy applications while running the tracker.

⚠️ Warning: Never interrupt the firmware update process by forcefully restarting your phone, which can cause the bracelet to “brickle” and stop turning on.

After a successful upgrade, the device will automatically restart, at which point the connection will be severed, wait for the Mi or Xiaomi logo to appear on the tracker screen and try again.
