How to Remove All Bluetooth Devices on Xiaomi: 5 Ways to Work

Stored Bluetooth devices on Xiaomi smartphones accumulate over time as digital garbage: old headphones, fitness bracelets, smartwatches or speakers remain in the system’s memory even if you have not used them for a long time. This not only clutters the list of available devices, but can also cause connection conflicts, slow scanning or even automatic reconnection to irrelevant gadgets. For example, if your Redmi Note 12 stubbornly clings to a neighbor’s column instead of the new Xiaomi Buds 4 Pro, the problem is precisely caches.

In this article, we’ll look at all the possible ways to remove Bluetooth devices on Xiaomi devices, from manually cleaning through the MIUI menu to radically resetting network settings. We’ll focus on the nuances for different firmware versions (including MIUI 14 and HyperOS), and solve typical problems like gray devices that don’t get removed in the standard way. If you’re faced with a smartphone “forgetting” a device just removed or it reappears after a reboot, here’s the solution.

Why You Should Remove Old Bluetooth Devices

At first glance, unnecessary entries on the list of connected gadgets seem harmless, but in practice they create a number of problems:

• 🔍 Slow scanning: The more devices in memory, the longer Xiaomi is looking for new ones. For example, connecting to the Mi Band 8 can take up to 30 seconds instead of the usual 5-10.
• 🔄 Autoconnect to irrelevant gadgets: A smartphone can cling to an old Mi Portable Speaker speaker instead of new headphones if it was once a priority.
• 🛠️ Profile conflicts: Some devices (e.g. Xiaomi Smart Door Lock) require exclusive connection.
• 🔋 Increased battery consumption: Background scans and attempts to connect to dead devices eat up to 5–7% of the charge per day.

In addition, MIUI has a bug (current for versions 12.5–14.0.5) where a remote device can return to the list after a reboot or system update, which is due to caching data in the Bluetooth Stack module, and we will discuss the solutions to this problem in the section on resetting.

⚠️ Note: If you use Xiaomi to connect to your car system (e.g. Android Auto or CarPlay via Bluetooth), removing the device will result in the loss of all stored media settings and contacts. → Google → Backup.

Method 1: Manual removal via Bluetooth menu

The most obvious method is to remove each device manually, which is suitable if you have no more than 10-15 records, the instructions are relevant for all Xiaomi, Redmi and POCO smartphones on MIUI 12-14 and HyperOS:

1. Open Settings (the gear icon on the main screen).
2. Go to Connections and Sharing → Bluetooth.
3. Activate Bluetooth if it is turned off (the slider at the top).
4. In the list of "Conjugated devices" tap on the desired gadget.
5. Click Unpair (or the basket icon in HyperOS).
6. Confirm the action in the pop-up window.

To speed up the process, you can use the selection mode (available in MIUI 14 and later):

• 📌 Tap and hold any device in the list.
• 📌 A checkbox will appear – mark all unnecessary gadgets.
• 📌 Slip the basket icon in the upper right corner.

If the device is not removed (button is inactive or error occurs), try:

Turn off Bluetooth and turn it back on.

Reboot your smartphone

Remove the device in Safe Mode (press the power button → "Safe Mode")

Update the firmware to the latest version-->

⚠️ Note: On some models (Xiaomi) 12T, Redmi K50) After deleting the device, it may remain on the list marked "Unconnected." This is a visual bug - the data is actually erased. To remove the record, clear the Settings app cache (Settings). → Annexes → Application management → Settings → Warehouse → Clear the cache).

Method 2: Reset Bluetooth settings (without data loss)

If manual deletion doesn’t work or devices come back after rebooting, apply a targeted reset of the Bluetooth module.This method does not affect other smartphone settings (Wi-Fi, mobile network, accounts), but completely clears all associated devices and cache.

Instructions for MIUI:

1. Open the Settings. → The phone.
2. Tap All settings (or additional settings in HyperOS).
3. Select Settings Reset.
4. Click Reset Bluetooth settings (in some firmware, the item is called Network Reset – then it will reset Wi-Fi!).
5. Confirm the action with a password or pattern lock.

For HyperOS (new Xiaomi 14, Redmi Turbo 3 models):

1. Go to Settings → Connections and Sharing → Bluetooth.
2. Slip on the three dots in the top right corner.
3. Select Reset Bluetooth settings.

After discharge:

• 🔄 Reboot your smartphone (required!).
• 🔍 Go to Settings. → Annexes → Application management → Bluetooth and clear the cache.
• 📱 Try to connect the desired device again.

Method 3: Cleaning through ADB (for power users)

If standard methods don't work, you can use ADB (Android Debug Bridge) commands to remove even those devices that are stuck in the system, and this requires connecting the smartphone to the computer.

What you need:

• 🖥️ Computer with Windows/macOS/Linux.
• 🔌 Cable USB (better-than-original).
• 📦 Installed drivers Xiaomi and ADB Tools.
• 🔧 Included debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI — Slip 7 times; then Settings → Additionally. → For developers → Debugging by USB).

Step-by-step:

1. Connect your smartphone to your PC and allow debugging (in the pop-up window on your phone, click Allow).
2. Open the command line (Windows) or terminal (macOS/Linux) in the adb folder.
3. Enter the command to check the connection: Adb devices should appear serial number of your Xiaomi.
4. Run the command to clean all Bluetooth devices: adb shell pm clear com.android.bluetooth
5. Reboot your smartphone: adb reboot

If the command fails (Operation not allowed error), try an alternative method:

adb shell


su




rm /data/misc/bluedroid/bt_config.conf




exit




exit

⚠️ Note: Su commands require root rights. On most Xiaomi smartphones, they can be obtained through unlocking the bootloader and installing Magisk, but this voids the warranty).

💡

Before using ADB, back up your data via Settings → Additional → Backup and Reset. In rare cases, cleaning a Bluetooth module can reset your mobile network settings.

Method 4: Complete reset of network settings (radical method)

If nothing works, you'll have to completely reset your network.

• 📶 All saved Wi-Fi networks and their passwords.
• 📱 Associated Bluetooth devices.
• 📡 Mobile network settings (APN).
• 📍 Geolocation data (if network location services were used).

How to do this:

1. Open Settings → About the phone → Reset settings.
2. Select Network Settings Reset (or Wi-Fi, Mobile Network, and Bluetooth Reset in HyperOS).
3. Confirm the action with a password / pattern lock.
4. Wait for the reboot (it will take 1-2 minutes).

After discharge:

• 🔄 Connect to Wi-Fi again.
• 🔊 Set up the parameters of the mobile network (APN Usually restored automatically).
• 🎧 Connect the right Bluetooth devices.

Method 5: Remove through the Engineering Menu (for advanced)

Xiaomi smartphones have a hidden engineering menu where you can reset Bluetooth settings at a low level, which helps if devices “ghostly” return after being removed or reset.

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636### The Testing menu will open.
3. Select Phone Information (or Usage Statistics in some firmware).
4. Scroll down and find the Bluetooth section.
5. Click Bluetooth Reset (or Clear BT Pairing Devices).
6. Confirm the action and restart the smartphone.

Alternative code for new models (Xiaomi 13/14, Redmi K60):

##232338##

⚠️ Warning: Do not change other options in the engineering menu unless you know what they are intended for! Incorrect settings can lead to network loss or overheating of the processor. TX Power can bring the wireless module out of order.

Solving Typical Problems After Removal

Even after successfully cleaning Bluetooth devices, Xiaomi users face a number of challenges, including the most common and ways to solve them:

If after all the manipulations the problem remains, check:

• 🔋 Battery charge: At level below 15% MIUI Automatically disables power-intensive modules, including Bluetooth.
• 📦 Firmware updates: In older versions MIUI (below 12.5) there are bugs with Bluetooth 5.0+. Update through Settings → The phone. → Updating the system.
• 🛠️ Hardware malfunctions: If the smartphone does not find any devices, the Bluetooth module may be damaged. Check it through the engineering menu (#4636## → Bluetooth Test).

💡

If none of these things work, the problem may be the hardware, and if you do, go to Xiaomi Service Center, and it costs 1,500 to 3,000 to repair a Bluetooth module. ₽ model-wise.
