How to completely clear the history of Bluetooth on Xiaomi smartphones: 5 working ways

Xiaomi smartphones (including the Redmi, POCO and Mi line) keep the history of Bluetooth connected devices for the convenience of users — so that you do not have to re-pair with headphones, speakers or fitness bracelets. However, over time, this list grows, and some devices stop connecting correctly, in such cases, you need a complete cleanup of Bluetooth history, but not everyone knows how to do it correctly.

In this article, you will find current ways to remove stored devices on MIUI 12-15, including hidden settings and reset the Bluetooth module through the engineering menu. We will also discuss why some devices are not removed in the standard way, and what to do if connection errors occur after cleaning. The instructions are suitable for all modern Xiaomi models, including Redmi Note 12/13, POCO X5/F5, Xiaomi 13/14 and others.

Why you should clean up Bluetooth history on Xiaomi

The list of connected devices in Bluetooth is not just a history of connections, but databases with unique identifiers (MAC-Addresses and encryption keys. Over time, this list can cause the following problems:

• 🔌 Automatic connection to irrelevant devices – the smartphone tries to connect to the neighbor’s column or old headphones that have not been used for a long time.
• 🔊 Connection conflicts – new devices can’t mate due to crowded cache or outdated profiles.
• 🔋 Increased battery consumption – Bluetooth module wastes energy on scanning and trying to connect to unnecessary gadgets.
• 🛡️ Security vulnerabilities: Stored devices with outdated protocols (e.g. Bluetooth 4.0) can be a point of attack for hackers.

For example, if you used to connect the Mi Band 3 to your phone and now use the Xiaomi Smart Band 8, an old fitness bracelet can interfere with the stable operation of a new one, as well as wireless headphones (for example, Redmi Buds 4 or Xiaomi FlipBuds Pro), which require a “clean” connection after reset.

Method 1: Standard Deletion of Devices through Settings

The easiest method is to manually remove unwanted devices via the Bluetooth menu, which works on all Xiaomi smartphones with MIUI 12-15 and does not require root rights or additional applications.

Instructions:

1. Open Settings → Connections and Sharing → Bluetooth.
2. Push the gear. ⚙️ Next to the name of the device you want to remove.
3. In the menu that opens, select Disable (if the device is connected), then Forget the device.
4. Confirm the action in the dialog window.

If the device doesn’t appear on the list but you’re sure it was once connected, try turning on Show System Devices (if there’s one in your version of MIUI).

Check that the right devices (headphones, watches) are connected to another phone

Write it down. MAC-addresses of important gadgets (located in their settings)

Make sure your smartphone is at least 30% charged.

Method 2: Reset Bluetooth settings via engineering menu

If standard deletion doesn’t work (for example, the device still automatically connects), you’ll have to use an engineering menu, which resets all Bluetooth settings, including cache and saved profiles.

Warning: After resetting, all the associated devices will be removed and will have to be reconnected!

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Phone Information (or Phone Information).
3. Scroll down to the Bluetooth section and press Bluetooth Reset (or Bluetooth reset).
4. Confirm the action and restart the smartphone.

⚠️ Note: On some Xiaomi models (e.g, POCO F4 or Redmi K50) In this case, use the alternative code: ##232338## It opens the Bluetooth test menu, which also has the option of resetting.

Method 3: Clearing the cache and data of the Bluetooth application

If the devices are deleted but reappear in the list after a while, the problem may lie in the cache of the Bluetooth app.Cache and data clearing will reset all temporary files, including possible pairing errors.

Instructions:

1. Go to Settings → Applications → Application Management.
2. Press three points. ⋮ in the upper right corner and select Show System Processes.
3. Find the Bluetooth list (or com.android.bluetooth) and open it.
4. Click Warehouse → Clear the cache and Clear the data.
5. Reboot your smartphone.

After this procedure, all the stored devices will be deleted and the Bluetooth settings will be reset to factory, a method that is especially useful if you encounter an error such as "Disconnected" or "Device not supported."

Method 4: Remove via ADB (for power users)

If standard methods don’t work, you can use Android Debug Bridge (ADB), a tool for debugging Android devices, which requires connecting your smartphone to your computer, but allows you to completely clean all stored devices, including those that are not displayed in the interface.

Instructions:

1. Install ADB Tools on your computer.
2. Activate Developer Mode on your smartphone: Settings → About Phone → MIUI version (shap 7 times).
3. Enable USB debugging in Settings → Additional → For developers.
4. Connect your phone to your PC and execute the commands: adb devices adb shell pm clear com.android.bluetooth adb shell rm /data/misc/bluedroid/bt_config.conf
5. Reboot your smartphone.

⚠️ Attention: Teams ADB Bluetooth can be unstable if executed incorrectly.Before using this method, back up your data via Mi Cloud or locally.

💡

If the devices are still displayed after cleaning through ADB, check the /data/misc/bluetooth folder for additional configuration files. These can also be deleted via ADB by adb shell rm -rf /data/misc/bluetooth/*.

Method 5: Reset all network settings (last resort)

If none of the previous methods worked, you'll have to completely reset your network settings, which will not only delete your Bluetooth history, but also your stored Wi-Fi networks, VPN settings, and mobile Internet data, and only use this method as a last resort!

Instructions:

1. Go to Settings → System and device → Additional → Resetting.
2. Select Network Settings Reset (or Reset Wi-Fi, Mobile & Bluetooth).
3. Confirm the action by entering PIN-code.
4. After the reboot, all network settings will be reset.

This method is guaranteed to remove all stored Bluetooth devices, but will require reconfiguration of the connection to Wi-Fi and mobile network, and we recommend pre-recording passwords from important networks.

💡

Network reset is the most radical method, but it works 99% of the time when other methods don't work. Use it if Bluetooth stops turning on or constantly gives out errors.

Frequent Errors and Their Solutions After Bluetooth Cleanup

After you delete your devices or reset your Bluetooth settings, you may have new problems, and here are the most common ways to solve them:

• 🔴 Bluetooth does not turn on – restart your smartphone or check if the module is disabled in Settings → Battery → Energy saving regime.
• 🔍 Devices are not searched for – make sure they are in pairing mode (e.g. headphones should flash blue lights).
• 🔄 Permanent connection breaks – Update your smartphone and device firmware (such as headphones or speakers) to the latest version.
• 📱 Phone doesn’t remember new devices – clear the Settings app cache (com.android.settings) through Settings → Annexes.

If problems persist, check if Bluetooth conflicts with other wireless modules. For example, some Xiaomi models (such as the Redmi Note 11 Pro+) can not simultaneously work Bluetooth and Wi-Fi 5 GHz. In this case, switch Wi-Fi to 2.4 GHz.
