How to Remove Bluetooth Devices from Xiaomi: The Complete Guide

Modern smartphones Xiaomi, Redmi and Poco accumulate a huge amount of data on connections, and over time the list of Bluetooth devices can turn into chaos. Often users are faced with a situation where the phone stops seeing headphones, watches or fitness bracelet, although previously everything worked stable. In such cases, standard reconnection does not help, and the only right solution is a complete cleanup of the list of associated gadgets.

The process of removing old profiles not only frees up the memory of the system cache, but also eliminates driver conflicts that can interfere with the work of new accessories. Resetting Bluetooth settings often solves problems with intermittent sound or inability to log in to car radios. It is important to understand that removing a device from the list is not just the disappearance of an icon, but the break of digital communication and clearing encryption keys.

In this article, we’ll look at all the ways you can manage connections, from the standard settings menu to the use of engineering modes. You’ll learn how to properly clean your connection history so that your smartphone works quickly and steadily. We’ll also look at the nuances of working with the MIUI shell and HyperOS, which have their own peculiarities in the organization of wireless interfaces.

Why You Should Remove Old Connections

Many users ignore the list of Bluetooth devices until they encounter critical connection errors. However, a crowded list of conjugate gadgets can negatively affect the speed of detection of new devices. The system spends resources on background scanning and trying handshake protocol with each of the saved profiles, even if they are out of reach.

Profile conflicts are another common reason to clean.If you've ever connected the same headphones after you dropped them or used a clone of the device, the phone may be confusing MAC-Addresses and miscalculations of the codec, which causes the sound to become quiet, intermittent, or even disappear.

In addition, removing unnecessary devices increases your digital security: In public places, attackers can exploit Bluetooth protocol vulnerabilities to track or attack like Bluejacking. The fewer devices that have automatic permission to connect to your phone, the lower the risk of unauthorized access to data.

• 📉 Resolving software conflicts between old and new drivers.
• 🚀 Accelerating the process of searching and pairing new accessories.
• 🔒 Improving the security of personal data using public networks.
• 🔋 Reducing background activity of the communication module and saving battery power.

Standard Remove Method through MIUI and HyperOS Settings

The most obvious and secure way to manage connections is built into the standard operating system menu. Regardless of the shell version, the algorithm of actions remains almost identical, although the names of the items may differ slightly, and first you need to go to the settings section responsible for wireless connections.

Open the Settings menu and find Bluetooth. The list that opens, "My Devices" or "Available Devices," will show all the gadgets your smartphone has ever connected to. Find the device you want in the list and click the arrow to the right of its name or hold your finger on the name of the gadget.

In the context menu that opens, select the option “Unpair” or “Forget device.” The system will request confirmation of action, as this will delete all stored profile data, including button settings and connection history. Once confirmed, the device will disappear from the list, and a full procedure (pairing) will be required for reuse.

It's worth noting that some versions of MIUI have a limit on how many devices you can store at the same time, although it's quite large. If you're using different headphones and trackers, periodically cleaning this list will be a good habit to keep the system in order.

Using a Bluetooth hidden menu for advanced users

For those who are faced with situations where the standard menu does not display the device or the Forget button is inactive, there is access to advanced settings through the engineering menu. This interface is designed for developers and testers, so you should handle it extremely carefully. Any changes here can affect the operation of the communication module as a whole.

To activate the developer menu, go to Settings → About Phone and quickly click 7-10 times on either MIUI Version or OS Version. After you notice that you have become a developer, go back to the main settings menu, select Additional and find the Developer Version.

Inside this section, scroll down to the Network or Bluetooth block. Here you will find the Bluetooth HCI snoop log switch and other technical settings. However, to directly remove "hang" devices, a command is more often used in the terminal or a debugging menu reset if the standard interface does not respond.

⚠️ Note: Do not change the settings of codecs or Bluetooth versions in the engineering menu without a clear understanding of their purpose.

If the ghost device is still on the list and is not removed, try the developer menu to find the option to Reset Bluetooth settings (if available in your firmware version).This action will force the Bluetooth stack to restart and clear the system-level pairing cache.

Comparison of Connection Cleaning Methods

The choice of removal method depends on the specific situation and the state of your smartphone software. Below is a table that will help determine the most suitable method for your case, taking into account the level of access and risks.

As you can see from the table, the standard method is enough for 95% of users, but if you are testing various gadgets or encounter a system bug, the transition to more complex tools is justified.

Solving problems with undeletable devices

Sometimes the system may not behave properly: the device appears in the list, but when you try to delete nothing happens, or it appears again after rebooting, a phenomenon often called the “glutch of the pairing cache.”

The first step should be to force the Bluetooth process to end. Go to Settings → Apps → Show all apps, search the “Bluetooth” list (may be called “Bluetooth MIDI Service” or simply “Bluetooth”), click Stop and Clear Data, which will reset the temporary service files without deleting user settings.

If that didn't work, you can use the command via ADB (Android Debug Bridge) by connecting the phone to your computer, and this method requires USB debugging enabled.

adb shell bmgr run com.android.bluetooth

This command forcibly triggers the backup manager for the Bluetooth module, which often helps to knock out the frozen processes, and after the command is executed, you need to restart the device.

• 🔄 Perform a reboot in Safe Mode to eliminate the impact of third-party apps.
• 🗑️ Clear the cache of the Bluetooth app through the App Management menu.
• 📱 Make sure that the device that is being removed also resets the network settings.

⚠️ Attention: Before use ADB-Make sure you understand the way they work. Incorrectly typing commands can cause the system to run in an unstable way.

Features of removing smart home devices

In the Xiaomi ecosystem, many smart home devices, such as lamps, sockets or scales, use Bluetooth Low Energy (BLE) for initial setup. Once linked to a Mi Home account, they can remain on the Bluetooth list as available for direct connection, even if the control is through a Wi-Fi gateway.

Removing such devices from the Bluetooth list can directly break communication with the application. It is critical to first remove the device from the Mi Home app, and only then clear the Bluetooth list. Otherwise, you can get a device that does not respond to commands from the phone or to a button reset.

The Mijia and Aqara series have long-lasting shutdown delays. After Forget Device in Bluetooth settings, the gadget can try to reconnect in the background for a few more minutes, and it is recommended to turn off such devices physically (unscrew the lamp or remove the battery) for 10-15 seconds after the program deletion.

💡

Tip: If the smart device is not removed, try to turn off the Internet on your smartphone before performing the “Forget the device” procedure, which will prevent the erroneous status from synchronizing with the cloud.
