Xiaomi fitness bracelet does not connect to the phone via Bluetooth: all the reasons and solutions

Have you bought a new Mi Band 7 or Xiaomi Smart Band Pro, but it stubbornly refuses to connect to a smartphone? Or the old bracelet suddenly fell off the Mi Fitness app? Bluetooth connectivity problems in Xiaomi fitness trackers are common — and not always the bracelet itself is to blame. In 80% of cases, the error lies in the settings of the phone, conflict of versions of the software or trivial things that users forget.

This article is not just a list of standard “reset your device” tips, but we will look at all possible causes, including rare ones (for example, a conflict with other Bluetooth devices or a lock). MAC-address bracelet system Android), and give step-by-step instructions for each model - from Mi Band 3 to Xiaomi Band 8 Pro. You will also learn how to distinguish hardware from software failure and when to contact the service.

For convenience, we've compiled FAQ-block with answers to frequent questions and a table of compatibility of bracelets with versions Android/iOS. If your case isn’t typical, check the Rare Error section, which describes problems like “the bracelet plugs in but shuts off immediately” or “the app sees the device but can’t complete sync».

1. Checking the basic connection conditions

Before digging deep into the settings, make sure the minimum requirements for synchronization are met.This will save you hours of time:

• 📱 Version of the phone OS: Android 6.0+ or iOS 12+. Xiaomi bracelets do not support legacy systems (for example, Mi Band 6 will not work on Android 5.1).
• 🔋 Bracelet charge: Battery level should be above 20%. At low charge, the bracelet can be turned on, but not transmit data over Bluetooth.
• 📲 Appendix: Installed the latest version of Mi Fitness (for global firmware) or Zepp Life (for Chinese versions) Older versions of apps often don't recognize newer wristbands.
• 🔄 Distance: Between the phone and the bracelet should be no more than 10 meters (no obstacles). Walls, metal objects and other Bluetooth devices (earphones, speakers) can cause interference.

If at least one of the conditions is not met, the bracelet will either not appear in the list of available devices, or the connection will be interrupted during the synchronization stage. For example, the Mi Band 5 at a charge level below 15% can only turn on the Bluetooth module for 30 seconds, which is not enough for full synchronization.

Important: If you use custom firmware on your phone (like LineageOS), check if it supports Bluetooth Low Energy (BLE).Some builds turn off BLE to save charge, making it impossible to plug in the bracelet.

2. Typical errors of users when connecting

Most problems arise from missteps in the first setup or after the bracelet is reset, and here are the most common mistakes:

• 🚫 Missed activation step: The bracelet needs to be first tied to a Xiaomi account in the app, not just plugged in like a regular Bluetooth device.If you're trying to connect the bracelet through Settings → Bluetooth on your phone, the connection will be unstable.
• 🔄 Wrong order: First turn on Bluetooth on your phone, then on your bracelet. If you do the opposite, the bracelet may not appear on the list of available devices.
• 📱 Conflict with other apps: Programs like Notify & Fitness or Tools & Mi Band can block the official Mi Fitness app. Uninstall third-party utilities for the bracelet before connecting.
• 🔒 Blocking permissions: On Android 11+ The Mi Fitness app must have permission to the exact location (yes, that's required for Bluetooth.

Critical error: If you previously connected the bracelet to another phone but didn’t untie it from your Xiaomi account, the new phone won’t be able to complete sync, in which case you’ll need to reset the bracelet to factory settings (see section 4).

3. Bluetooth problems on the phone

If the bracelet doesn't show up in the list of available devices or the connection is constantly disrupted, the problem may be in the phone's Bluetooth module.

1. Test on other devices: Try connecting the bracelet to another smartphone or tablet, and if the connection is successful, the problem is in your phone.
2. Compatibility Check: Some phones (especially budget models on MediaTek) have limits on how many Bluetooth devices are connected at the same time.
3. Reset Bluetooth settings: On Android go to Settings → System system → Reset → Reset your Wi-Fi, mobile network and Bluetooth settings. On iPhone: Settings → Mainstream → Transfer or discharge → Reset → Reset the network settings.

Pay special attention to the power saving mode. On Xiaomi, Redmi and POCO phones, Background Limitation (in battery settings) can block Bluetooth from running in the background. Add the Mi Fitness app to the No Limits list.

💡

If you have a Xiaomi phone, turn off the dual Bluetooth connection function in Bluetooth settings before connecting the bracelet. BLE-device.

4. Resetting the bracelet to factory settings

If the bracelet was previously tied to another phone or "hang" during synchronization, a complete reset will help.

• 🔄 Mi Band 3/4/5/6/7: Press the touch button on the bracelet on 10–15 seconds until the vibration and the Mi logo appear. Once reset, the bracelet automatically reboots.
• 🔄 Xiaomi Smart Band Pro: Go to Settings → System system → Reset settings on the bracelet itself (scroll through the menu with swipes).
• 🔄 Mi Band 2: Turn off the bracelet from charging, press the physical button for 20 seconds until the indicator flashes.

Once reset, the bracelet will be like a new one, it needs to be re-associated with the Xiaomi account via the app. Warning: All data on the bracelet (steps, sleep history) will be deleted. If it has not synced with the phone before, it will not be possible to restore it.

5. Conflicts with the firmware of the bracelet or telephone

Connection errors often occur due to software version incompatibility. For example, Mi Band 7 with firmware 1.10.5.0 may not connect to Android 13 phones due to changes in the BLE protocol.

Update of the bracelet firmware:

1. Open the Mi Fitness app and go to the bracelet profile.
2. Click on the three dots in the top right corner and select Firmware Update.
3. If the update is not available, check the region of the Xiaomi account (should match the region of the bracelet).

Reverse phone firmware (for experienced users):

If the problems started after the MIUI/iOS update, you can temporarily roll back to the previous version. For example, on Xiaomi this is done via Fastboot or Recovery.

💡

If the bracelet plugs in but shuts off immediately, check the firmware version. You probably need to upgrade either the bracelet or the phone.

6. Rare causes and hardware malfunctions

If all previous steps failed, the problem could be hardware or related to rare software failures:

• 🔌 Charging connector damaged: If the bracelet doesn't charge to 100% or shuts down at the slightest movement, the Bluetooth module's contact may have gone off.
• 📡 Interference from other devices: 2.4GHz routers, wireless headphones and even microwave ovens can cause interference. Try connecting elsewhere.
• 🛡️ Lockdown MAC-Addresses: On some phones (especially corporate phones), the administrator may block the connection of unknown Bluetooth devices.
• 🔄 Failure in NVRAM: MediaTek phones may fly section NVRAM, Bluetooth and Wi-Fi, and in this case, only flashing it will help.

If the bracelet does not turn on or does not respond to charging, check:

• Integrity of cable (especially in the Mi Band 6/7, where the plug breaks easily).
• The presence of moisture under the body (even if the bracelet did not sink, the condensate could damage the board).
• The charger is operational (try charging from Power Bank).

⚠️ Warning: If the bracelet fell from a height or was subjected to severe blows, the Bluetooth module could move away from the motherboard, in this case, repair is possible only in a service center with soldering equipment.

7. Specific errors and their solutions

Some problems are so rare that they're hard to diagnose, and we've collected some of the more non-obvious cases.

Special case: If you use custom firmware on your bracelet (such as the Amazfit Mod), it may not be compatible with the official app, in which case you will have to return to stock firmware through Mi Band Tools.
