Xiaomi Mi Band bracelet doesn’t connect to phone – a complete guide to fixing a problem

Why is Xiaomi Mi Band bracelet not connected to phone?

Xiaomi Mi Band smart bracelets (including Mi Band 4/5/6/7 and Smart Band Pro models) usually connect to the smartphone via Bluetooth without problems. But sometimes users face a situation when the gadget is no longer defined in the Mi Fitness app (formerly Mi Fit) or does not appear in the list of available devices at all. The reasons can be both software (software failure, outdated firmware) and hardware (a discharged battery, a damaged Bluetooth module).

In this article, we will look at all possible causes and ways to eliminate them, from basic checks to complex firmware manipulations. Importantly, if the bracelet is first connected, the algorithm will be different from when it previously worked, but suddenly stopped synchronizing. Also consider that models Mi Band 7 Pro and later may require a Zepp Life application instead of Mi Fitness.

Before you start taking action, answer two key questions:

1. Does the bracelet react to touch (the screen lights up when you press a button or sensor)?
2. Is Bluetooth enabled and geodata allowed for Mi Fitness/Zepp Life?

If the answer to any of them is “no”, the problem lies in the basic settings – and its solution will take no more than 5 minutes.

1. Checking basic parameters: battery, Bluetooth and resolutions

Start with the basics, often the problem is solved at this point. The first thing to do is make sure the bracelet is charged. Even if the charge is displayed on the screen, try plugging it into the charger for 10-15 minutes. Mi Band 4 and older models at a charge below 5% may not turn on or appear in the search.

Next, check:

• 📱 Bluetooth on your phone: Is it on the Quick Settings panel? Try turning it off and turning it back on.
• 🔒 Application permissions: go to Settings → Applications → Mi Fitness/Zepp Life → Permissions and enable: Access to geodata (required!) Bluetooth management permission Display over other windows (for some versions of Android)
• 🔄 Phone reboot: Sometimes system failures block peripheral devices from connecting.

If the bracelet was previously connected but is not now identified, try removing it from the list of conjugated devices in your phone's Bluetooth settings.

1. Open Settings → Bluetooth.
2. Find your Mi Band (usually displayed as MI Band X or Mi Smart Band) in the list.
3. Click on the gear next to the name and select “Forget the device”.

💡

On some Xiaomi smartphones (such as the Redmi Note 10 Pro), the built-in Bluetooth Optimization feature can block the bracelet from connecting. Disable it in Settings → Bluetooth → More.

2. reset Xiaomi Mi Band bracelet to factory settings

If the basic checks don't work, the next step is to hard-reset the bracelet, which will remove all the data from the device (steps, pulse, settings), but often solves connection problems.

Once reset, the bracelet will reboot and show you the pairing code (e.g., 123456). Now try reconnecting it via the Mi Fitness or Zepp Life app.

Make sure the battery charge is > 20%|

Take a picture of your current settings (if important) |

Turn off the bracelet from your phone in Bluetooth|

Prepare a pairing code (usually 123456)

-->

If the bracelet does not respond to touch and does not allow you to reset through the menu, try a forced reset:

1. Connect the bracelet to the charger.
2. Hold the touch button (or screen area) for 15-20 seconds until the Mi logo appears.
3. Release the button - the bracelet will reboot in factory condition.

3. Mi Fitness/Zepp Life application problems: update, reinstallation, cache

Often, it's not the device itself that's to blame, but the software, and Mi Fitness and Zepp Life can get stuck because of an outdated version, a corrupted cache, or a conflict with other services.

Step 1. Update the app

• 📲 For Android: Open Google Play, search for Mi Fitness or Zepp Life, and click Update.
• 🍎 For iPhone: Check for updates in the App Store.

Step 2: Clear the cache and data (Android only):

1. Go to Settings → Applications → Mi Fitness → Storage.
2. Click on Clear Cache and Clear Data (Warning: This will delete all stored data about steps, sleep, etc.).
3. Reboot the phone.

Step 3: Reinstall the application

If updating and cleaning the cache didn't help, uninstall the app and install it again. For Android, additionally:

• Before installing, turn off battery optimization for the app (in your phone settings).
• Allow auto-run (on some firmware, such as MIUI, this is critical).

💡

On iPhone, Xiaomi Mi Band bracelets may not connect due to iOS restrictions. Try disabling Device Limit in Bluetooth settings or use an Android smartphone for initial setup.

4. Conflicts with other devices and phone firmware

Sometimes the Xiaomi bracelet does not connect due to conflicts with other Bluetooth devices (earbuds, speakers, car system) or features of the phone’s firmware.

Problem 1: Phone “sees” bracelet, but does not connect

• 🔌 Disconnect all other Bluetooth devices from your phone.
• 📵 Turn on flight mode for 10 seconds, then turn it off.
• 🔄 Reset the bracelet (hold the button for 5 seconds).

Problem 2: The bracelet is plugged in, but immediately shut down.

This is typical of phones with aggressive battery optimization (e.g. Xiaomi, Samsung, Huawei).

1. Go to Settings → Battery → Battery Optimization.
2. Find Mi Fitness/Zepp Life and select No Limits.
3. Enable auto-run for the application (in permission settings).

Problem 3: Incompatibility with custom firmware

If your phone has unofficial firmware installed (e.g. LineageOS, Pixel Experience), you may have problems with Bluetooth LE (Low Energy), which is used by Mi Band bracelets.

• 🛠️ Update the firmware to the latest version.
• 🔧 Install Bluetooth Fix module via Magisk (for rooted devices).

1. Activate the developer mode (click 7 times on the build number in Settings → About phone).
2. Turn on Settings → System → Developers → Disable the improved Bluetooth.

5. Updating the bracelet firmware manually

If the bracelet is detected in the app but does not update automatically, try a forced firmware update. This is true for Mi Band 4 and later models. Important: the process requires a stable Internet connection and a charge of more than 50%.

Instructions for Mi Fitness/Zepp Life:

1. Open the app and connect to the bracelet.
2. Go to Profile → Your Device → Update Firmware.
3. If a new version is available, click “Update”.
4. Do not turn off Bluetooth or close the app until it is completed (it may take 5-10 minutes).

Manual firmware through files (for experienced users)

If the automatic update doesn't work, you can manually flash the bracelet through the Mi Band Tools utility (requires Android and root access or ADB).

1. Download the latest firmware for your model from the AmazfitWatchFaces website.
2. Install the Mi Band Tools app from Google Play.
3. In the application settings, select Firmware update and specify the path to the downloaded file.

6. Hardware malfunctions: when to contact the service

If none of the software methods worked, the problem may lie in the hardware of the bracelet or phone, and here are signs that it is time to carry the gadget for repair:

• 🔋 The bracelet does not charge (does not respond to the charger, does not warm the contact pad).
• 📡 The phone’s Bluetooth module doesn’t work with other devices (earphones, speakers).
• 💥 The bracelet fell into the water or was physically impacted (cracks on the body, bloated battery).
• 🔄 Once reset, the bracelet is not switched on or hangs on the Mi logo.

What you can do on your own:

• 🔍 Check the charging contacts on the bracelet -- they're often oxidized. Rub them with alcohol and cotton swab.
• 🔋 Try another charger (use the original Xiaomi cable).
• 📱 Connect the bracelet to another phone (preferably on pure Android, such as Pixel or Nokia).

When to contact the service:

• If the bracelet is warranty, do not disassemble it yourself!
• If after falling or getting moisture, it stopped turning on.
• If the phone’s Bluetooth module doesn’t work with any devices.

💡

The cost of repairing the Xiaomi Mi Band bracelet often exceeds the price of a new device. For example, replacing the battery in the Mi Band 6 can cost 1,500–2,000 ₽, whereas a new bracelet costs ~2,500 ₽.

7. Alternative ways of connecting (for advanced users)

If standard methods don't work, you can try informal solutions, which require technical skills, but sometimes help bring the bracelet back to life.

Method 1: Connecting with ADB (Android Debug Bridge)

If the bracelet is detected in the system, but the application does not see it, try resetting Bluetooth settings via ADB:

adb shell pm clear com.xiaomi.hm.health


adb shell pm clear com.miui.bluetooth

After completing the commands, restart the phone and try to connect again.

Method 2: Using Third-Party Applications

Applications like Notify & Fitness or Mi Band Master sometimes work where official software fails, and note that they may not support all features (e.g., Mi Pay or firmware updates).

Method 3: Firmware via nRF Connect (for Mi Band 4/5)

This is an extreme method, requiring a Bluetooth adapter with Nordic Semiconductor support (e.g., CSR 4.0).

1. Install nRF Connect on your PC.
2. Connect the bracelet in DFU mode (hold the button when connecting to charging).
3. Download the firmware through the utility.

💡

Before using informal methods, backup your bracelet data via Mi Fitness (if it connects at all). To do this, export the history to Profile → Settings → Export data.
