Xiaomi bracelet doesn’t connect to phone – what to do in 2026?

Xiaomi Mi Band fitness bracelets have long been the standard for tracking activity, but even proven devices have crashes. One of the most common problems is when the bracelet stops connecting to the smartphone. You see the words "failed to connect" in the Mi Fitness app (formerly Mi Fit), the indicator on the bracelet flashes, but synchronization does not occur. What is the reason and how to return to work?

The reasons can be found in software errors (outdated firmware, application conflict) and hardware malfunctions (a dead battery, a damaged Bluetooth module). In this article, we will analyze all possible scenarios, from basic checks to complex firmware manipulations. Instructions are relevant for Mi Band 3/4/5/6/7/8 models, Xiaomi Smart Band 7 Pro and other devices on the Zepp OS platform.

1. Basic checks before setting up

Before you start complex manipulations, make sure that the problem is not in the obvious trifles: 60% of the time, the bracelet does not connect due to trivial user errors.

Start by checking the battery power of the bracelet. If the charge level is below 10%, the device may not appear in the list of gadgets available for connection. Connect the bracelet to charge for 15-20 minutes - the indicator should light up in green or red. Also make sure that the Bluetooth on the smartphone is on and in search mode (not in power saving mode).

• 🔋 Bracelet charge: Connect to the charger for 10-15 minutes. If the indicator does not burn, the problem is in the battery or cable.
• 📱 Bluetooth on your phone: Go to Settings → Connections → Bluetooth and activate the function. Make sure the phone is not in "Airplane" mode».
• 🔄 Reboot devices: Reboot both the bracelet (press the touch button for 10 seconds) and the smartphone.
• 📶 Distance between devices: Maximum distance for stable connection is 10 meters without obstacles. Walls and furniture can block the signal.

⚠️ Note: If the Xiaomi bracelet is dead and does not respond to charging, try using another cable or power supply. Some models (such as the Mi Band 5) require an original charger with a magnetic connector.

2.Problems with Mi Fitness (Zepp Life)

Since 2023, Xiaomi has moved all fitness bracelets to the Zepp OS platform, and the Mi Fit app has been replaced by Mi Fitness (in some regions, Zepp Life).

The first thing you need to do is update the app to the latest version through Google Play or the App Store, and if there are no updates, uninstall the program and reinstall it.

• 📲 Android: Go to Settings → Annexes → Mi Fitness → Permissions and enable Bluetooth access, Warehouse, Notifications.
• 🍎 iOS: Open Settings → Confidentiality → Bluetooth and make sure that Mi Fitness has access.
• 🔄 Cache reset: In the app settings (Android) click "Storage" → Clear the cache. On iOS, uninstall the app and reinstall it.

If the bracelet is still not connected, try to log in to another Mi Account. Sometimes the problem lies in the failure of sync with Xiaomi servers.

1. Open Mi Fitness and go to profile.
2. Click "Exit" and log in again.
3. Try adding the bracelet as a new device.

3. Resetting the bracelet to factory settings

If the basic methods didn’t work, the next thing to try is a hard reset of the bracelet, which will remove all the data from the device (steps, pulse, settings), but often solves connection problems.

Instructions for different models:

Once reset, the bracelet will automatically reboot. Now try reconnecting it via Mi Fitness:

Open Mi Fitness and press + (Add Device)|

Select a bracelet model from the list |

Bring the bracelet to the phone at a distance of < 5 cm|

Confirm pairing on both devices |

4.Bluetooth problems on the phone

If the bracelet doesn’t appear on the list of available devices, the problem may be in the smartphone’s Bluetooth module. On Android, frequent errors are due to profile conflicts, and on iPhone, with iOS limitations.

For Android:

• 🔧 Cleaning up Bluetooth cache: Go to Settings → Annexes → Show system-based → Bluetooth → press "Storage" → Clear the cache».
• 📱 Developer Mode: Enable it (7 times click on “Build Number” in your phone settings), then activate “Bluetoothbug Debugging” in Developer Settings».
• 🔄 Switching Bluetooth mode: Some phones (such as Xiaomi or Samsung) have a separate "Bluetooth Audio" mode.

For the iPhone:

• 🍏 Reset Network Settings: Go to Settings → Mainstream → Transfer or discharge → Reset → Reset the network settings. This will delete all stored Bluetooth devices.
• 🔒 Confidentiality Limitations: In Settings → Confidentiality → Bluetooth check that Mi Fitness has access.
• ⚠️ iOS 17+: Newer versions of iOS may block connection to devices without MFi certification. Try connecting via another Android phone.

⚠️ Note: Some Xiaomi phones (e.g. Redmi Note) 10/11) The built-in dual apps feature can create conflicts. Remove the Mi Fitness duplicate if you have one.

💡

If the bracelet connects to another phone but not yours, the problem is definitely your smartphone. Try disabling VPNs, antivirus or power saving modes that can block Bluetooth connections.

5. Update of bracelet firmware

Outdated firmware is one of the main reasons for Mi Band’s unstable performance. Xiaomi regularly releases updates that fix connection errors, but they are not always installed automatically.

To update the firmware:

1. Connect the bracelet to charging and make sure the charge is not below 50%.
2. Open Mi Fitness and go to the section of your bracelet.
3. Press three points (⋮) in the upper right corner and select “Firmware Update».
4. If the update is available, confirm the installation and wait until the bracelet is completed (don’t turn off the charging!).

If the Mi Band 7/8 bracelet doesn’t update through the app, try hand firmware via Mi Band Tools (requires root on Android) or Notify & Fitness (for non-root devices).

⚠️ Warning: Do not interrupt the firmware update process! If the bracelet freezes during the installation phase, it can only be restored via Fastboot (this will require a special cable and PC).

6 Conflicts with other devices and applications

Xiaomi’s bracelet may not connect due to conflicts with other gadgets or programs that use Bluetooth, for example, if you already have headphones, smartwatches or a car system connected, they can block the connection.

How to check:

• 🎧 Disable all Bluetooth devices: Headphones, speakers, keyboards – anything that is wirelessly connected.
• 📱 Close background apps: Especially those that use Bluetooth (e.g. Spotify, Google Maps, Waze).
• 🛡️ Turn it off. VPN/Antivirus: Some programs (for example, Kaspersky, Avast) block connection to fitness bracelets.
• 🔄 Change Bluetooth Mode: Switch from Bluetooth Audio to Bluetooth Low Energy on Android (BLE)» developer-setting.

If you use multiple fitness apps (like Google Fit + Mi Fitness), they may conflict.

Mi Fitness → Profile → Settings → Data Synchronization → Disable All

💡

If the bracelet connects to your phone but the data isn't synced, the problem is the application conflict: Remove all fitness trackers except Mi Fitness, and try again.

Hardware malfunctions and repairs

How to check the hardware serviceability:

1. Connect the bracelet to another phone, and if it works, it's a problem in your smartphone.
2. Try charging the bracelet from another cable/power supply.
3. Light a flashlight on a screen in a dark room – if the image is barely noticeable, the problem is in the backlight.
