The list of Bluetooth devices on Xiaomi smartphones will eventually fill up with unnecessary gadgets: old headphones, speakers, fitness bracelets or car systems. This not only creates a visual clutter in the connection menu, but can also cause conflicts when pairing with new devices, for example, if your Redmi Note 12 stubbornly clings to old AirDots instead of new Buds 4 Pro, or the POCO X5 refuses to connect to the car because of a stored โghostโ device.
In this article, weโll look at all the ways you can clean up your Bluetooth list, from manually removing each device to completely resetting the module through an engineering menu, and focus on the hidden MIUI 14 settings that allow you to massively remove devices without a routine click on each item, and learn how to fix common errors like โfailed to connectโ or endlessly searching for devices after cleaning.
Why you should clean up the Bluetooth list on Xiaomi
At first glance, saved Bluetooth devices donโt take up much space and donโt affect performance, but in practice, a clogged list can create serious problems:
- ๐ Automatic connection to irrelevant devices: A smartphone may try to connect to old headphones instead of new ones, resulting in delayed or no sound.
- ๐ซ Conflicts MAC-If you have connected the same device several times (for example, after a reset), duplicates with different identifiers may remain on the list.
- ๐ Increased battery consumption: Bluetooth uses energy to scan and try to connect to stored but inaccessible devices.
- ๐ Pairing errors: Some devices (especially car multimedia systems) refuse to connect if there are "hang" records on the list.
On Xiaomi with MIUI 12-14, the problem is compounded by the fact that the system can cache Bluetooth data even after manual deletion.This means that simply clicking "Forget device" is not enough - it requires a complete cache clearing or module reset.
โ ๏ธ Note: If you use the Mi Band or other Xiaomi wearable devices, removing them from the Bluetooth list will cause you to disconnect from the Mi Fitness app. Before cleaning, make sure you have a backup of your workout data!
Method 1: Manually remove devices through settings
The most obvious method is to remove each device manually, which is best if you have no more than 5-7 devices on your list.
- Open the Settings app on your Xiaomi.
- Go to Connections and Sharing โ Bluetooth.
- Activate Bluetooth if it is turned off (not necessary to view the list).
- Push the gear. โ๏ธ Next to the name of the device you want to remove.
- In the menu that opens, select Forget this device (or Remove in older versions of MIUI).
- Confirm the action in the pop-up window.
For devices with MIUI 14 (such as Xiaomi 13 or Redmi Note 12 Pro+), the interface may be slightly different:
- ๐ฑ Instead of a gear, there might be a button. โฎ (three dots) next to the device name.
- ๐ In some firmware, the option is called Disable and Forget.
- ๐ Nana POCO F5 Other models with โcleanโ Android (without any other devices) MIUI) The way will be: Settings โ Connected devices โ Bluetooth settings โ Previous devices.
Make sure the device is off or out of range
Check if there are any active calls or file transfers over Bluetooth
Remember or write down. MAC-addresses of important devices (in case of problems with re-pairing)
Turn off the Auto Connection option in Bluetooth settings (if any)
-->
The main drawback of this method is the duration. If you have 20+ devices on your list, it takes 10-15 minutes, and it doesn't clear the cache of the Bluetooth module, so connection problems can persist.
Method 2: Mass removal through engineering menu (hidden function)
MIUI has a hidden engineering menu that allows you to reset all Bluetooth settings with a single click, which works on most Xiaomi, Redmi and POCO devices with MIUI 11 firmware and later, and importantly, after reset, all stored devices will be deleted without recovery.
Instructions:
- Open the phone (calling) application.
- Enter the combination: ##4636## (this is a universal code for accessing the test menu).
- In the menu that opens, select Phone Information (or Phone Information).
- Scroll down to the Bluetooth block.
- Click on Bluetooth test (or BT Test Mode).
- In the new window, select Clear BT Pairing Devices.
- Confirm the action.
On some models (for example, Xiaomi 12T or Redmi K50) the path may be different:
Testing Menu โ Hardware Testing โ Bluetooth โ Clear Pairing DevicesAfter this operation has been performed:
- ๐ฑ All stored devices will be removed from the list.
- ๐ Bluetooth settings will reset to factory (including device name).
- ๐ Temporary problems with connection to previously coupled devices (repairing required).
โ ๏ธ Attention: On devices with MIUI 14 and later, access to the engineering menu may be limited. If the code ##4636## does not work, try an alternative method through the ADB (described in Method 4).
Once a month
Only when problems arise
Never cleaned.
I don't know what to clean up.

Method 3: Reset network settings (including Bluetooth)
If the engineering menu is not available or not working, you can use the network reset function, which deletes all stored Wi-Fi networks, mobile Internet data and associated Bluetooth devices, and is suitable for Xiaomi on MIUI and Android One (for example, Mi A3 or POCO M3).
How to perform the reset:
- Open Settings โ System and Device โ Additional (on MIUI 14, the path can be Settings โ Memory โ Resetting).
- Select Network Settings Reset (or Wi-Fi, Mobile Network, and Bluetooth Reset).
- Enter. PIN-code or pattern lock, if required.
- Confirm the reset by clicking Reset Settings.
What happens after the reset:
| Type of data | Removed? | Effects of consequences |
|---|---|---|
| List of Bluetooth devices | โ Yes. | All the connected devices will be removed. Reconnection is required. |
| Saved Wi-Fi networks | โ Yes. | I'll have to re-enter the passwords. |
| Mobile Internet settings (APN) | โ Yes. | 4G/5G settings can be reset (usually automatically restored). |
| Name of Bluetooth device | โ Yes. | It will be back to factory (for example, Redmi Note 11). |
| Files and applications | โ No. | The reset only affects network settings. |
This method is most reliable if you encounter Bluetooth system errors, such as:
- ๐ด The device does not find new gadgets for pairing.
- ๐ด Constant communication breaks with connected devices.
- ๐ด Error "failed to connect" when trying to pair.
๐ก
Before resetting your network settings, take screenshots of a list of saved Wi-Fi networks (especially if you use hidden networks or complex passwords), which will save time after the reset.
Method 4: Cleaning through ADB (for advanced users)
If standard methods didn't work, you can use Android Debug Bridge (ADB), a debugging tool that allows you to execute commands directly on the system, which is suitable for users who are willing to work with the command line. Advantage: ADB allows you to clear the Bluetooth cache and reset the module settings at the system level, which is impossible to do through the standard interface.
What you'll need:
- ๐ฅ๏ธ Computer with drivers installed ADB and Fastboot.
- ๐ฑ Xiaomi smartphone with enabled debugging USB.
- ๐ USB-cable (preferably original).
Step-by-step:
- Turn on Developer Mode on your smartphone: Go to Settings โ About Phone โ MIUI Version. Click on MIUI Version 7 times in a row until the notification โYou became a developerโ appears.
Settings โ Additional โ For Developers
- USB debugging
- Unlocking OEM (if any)
- Connect your smartphone to your computer and confirm the debugging permission on the phone screen.
- Open the command prompt (Windows) or terminal (macOS/Linux) and type: adb devices Make sure your device appears in the list.
- Follow commands for Bluetooth reset: adb shell pm clear com.android.bluetooth adb shell settings put global shell settings bluetooth_on 0 adb shell settings put global bluetooth_on 1
- Reboot your smartphone.
What these teams do:
- ๐งน pm clear com.android.bluetooth โ clears the cache and data of the Bluetooth module.
- ๐ settings put global bluetooth_on 0/1 โ switches off and turns on Bluetooth at the system level (emulates a module reboot).
โ ๏ธ Attention: Use ADB It can cause Bluetooth to be unstable if the instructions are not executed correctly. Don't interrupt the process or turn off the cable while executing commands. If Bluetooth stopped working completely after resetting, try restarting the phone or performing an adb shell am broadcast command. -a android.bluetooth.adapter.action.STATE_CHANGED --ez android.bluetooth.adapter.extra.STATE 12.
What if the ADB canโt see the device?
Method 5: Completely reset your phone (last resort)
If none of these methods work, the last option is to reset your phone to factory settings, a radical solution that will remove not only the Bluetooth list, but all the data on your device, and only use it in case of critical problems, such as:
- ๐ด Bluetooth does not turn on or off immediately.
- ๐ด The smartphone does not find any device to pair.
- ๐ด Persistent errors com.android.bluetooth in the system logs.
How to perform the reset:
- Create a backup of important data (photos, contacts, messages).
- Open Settings โ About Phone โ Backup and Reset.
- Select Reset (or Reset all settings).
- Choose Delete all data and confirm the action.
- Wait for the process to be completed (it will take 5-10 minutes).
After discharge:
- ๐ฑ All Bluetooth devices will be removed.
- ๐ Network settings, accounts and installed apps will reset.
- ๐ There may be problems activating some features (such as Mi Account or Google Pay) if the phone has been linked to an account.
To minimize data loss, before resetting:
- ๐ Sync your contacts and calendar with your Google Account.
- ๐ Copy photos and videos to your computer or cloud (Google Photos, Mi Cloud).
- ๐ Save the list of installed applications (can be done through Settings) โ Annexes โ All applications โ โฎ โ Exports of the list).

A complete phone reset should be the last option. In 90% of cases, Bluetooth problems are solved in the first four ways. If the reset does not work, a hardware malfunction of the Bluetooth module is possible.
Solving Typical Problems After Cleaning Bluetooth
Even after successfully clearing the Bluetooth list, you may find it difficult to reconnect your devices, and here are the most common problems and solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| The device is not on the list of available | Old cache data interferes with scanning | Execute the command through ADB: adb shell am broadcast -a android.bluetooth.adapter.action.DISCOVERY_STARTED |
| Permanent communication breakdowns | Conflict MAC-post-reset | Remove the device on your smartphone and on your gadget (for example, in headphones), then pair again. |
| The "failed to connect" error | Incompatibility of Bluetooth profiles | In Bluetooth device settings, select "Use as Media Audio" or "Calling Only" |
| Bluetooth is turned on but does not find devices | Failure of the antenna or module | Try to turn on Flight Mode for 30 seconds, then turn off |
If you connect Xiaomi to an in-car multimedia system (such as Android Auto or CarPlay), after cleaning Bluetooth, you may need to:
- ๐ Re-enter PIN-pairing code (usually 0000 or 1234).
- ๐ Reboot the multimedia system of the machine.
- ๐ฑ Update the firmware of the car system (if available).
For devices with MIUI 14 and later (such as Xiaomi 13 Ultra or Redmi K60 Pro) after Bluetooth cleanup, it is recommended to:
- Reboot the smartphone.
- Turn Bluetooth on and off 2-3 times in a row.
- Check for system updates (Settings โ About Phone โ System Update).
