How to remove Bluetooth device on Xiaomi Android

Modern Xiaomi, Redmi and POCO smartphones are all overgrown with wireless connections that make life much easier. However, sometimes you have to clear the list of saved gadgets, whether it’s selling an old headset, losing headphones or just wanting to clean up the digital space. The process of untieing accessories on the shell of MIUI or HyperOS has its own features that differ from pure Android.

In this article, we will take a closer look at all the ways to remove pairing profiles, learn how to forcefully break a connection if the device is not responding, and why it is important to protect your data. We will also touch on the nuances of working with different versions of the Android operating system, since the menu layout can vary depending on the model of your Xiaomi.

Not only will we break down standard methods through settings, but we'll also explore deeper ways to manage Bluetooth stacks. Understanding how the system stores data about connected devices will help you avoid common mistakes. Proper connection management is not only a convenience, but also an important aspect of your smartphone's energy efficiency.

Why Remove Old Bluetooth Connections

At first glance, it may seem like having a dozen old headphones or speakers on the list is not harmful. However, the Android operating system periodically scans the airwaves for previously familiar devices to instantly restore connection, which leads to unnecessary battery consumption, especially if you are in crowded places where there are many other people's gadgets.

In addition, the accumulation of pairing profiles can cause software conflicts. A smartphone can try to automatically connect to a device that is on the verge of range, creating permanent communication breaks and audio interference. Cleaning the list of associated devices often solves the problem of spontaneously turning off sound during a conversation or listening to music.

From a security perspective, removing unknown or old devices is critical. If you've ever connected to public Bluetooth points or other speakers in parks, the profile could be stored in memory. Attackers could theoretically exploit protocol vulnerabilities to gain access to a device if it is recognized as trusted.

• 🔋 Reduce background activity and save battery energy by stopping constant searches.
• 🛡️ Improving the security of personal data and preventing unauthorized access.
• ⚡ Eliminating software conflicts that cause interface lags or sound problems.
• 🧹 Release of system cache associated with wireless module drivers.

⚠️ Before selling or transferring a smartphone to a new owner, be sure to completely reset all Bluetooth connections. Otherwise, the new owner may gain access to your connection history or, in rare cases, your phone will automatically try to connect to its gadgets.

Standard method of removal through MIUI settings

The simplest and safest method of untie accessories is built into the standard settings menu. The interface of the MIUI shell and the new HyperOS is almost identical in this aspect, so the instruction will suit most models, from the budget Redmi Note to the flagship Mi. First you need to activate the wireless module, even if the device you want to remove is now turned off.

Go to the settings section and find the connection section, which, depending on the firmware version, may be simply called "Bluetooth" or hidden inside the Connect and Sharing menu, and displays a complete list of all the gadgets that have ever been paired, not just the ones that are right now nearby.

Find the name of your device on the list, and next to it is usually the gear icon or the arrow to the right that opens the additional menu, and that's where the "Unpair" or "Forget the device" button is hidden, and you click on it, you delete the encryption keys and the profile from the phone's memory.

• 📱 Open the Settings app on the home screen or in the notification curtain.
• 📶 Go to Bluetooth or Connect and Sharing.
• 🔍 In the list of “My devices” or “Coupled devices” find the desired gadget.
• ❌ Click on the settings icon next to the device name and select “Cancel pairing».

Once you do this, the device will disappear from the list of available devices, so if you want to reconnect it, you'll need to re-enter the device into search mode and enter the confirmation code if you need it, which will ensure that the connection is installed from scratch.

Remove via Quick Access Panel

For those who appreciate speed, there is a faster way to manage connections that doesn’t require a deep dive into the settings menu. The Control Center in Xiaomi smartphones lets you interact with active Bluetooth devices in a couple of touches, a method that is especially convenient when you need to quickly switch between headphones or turn off the extra one.

To use this method, swipe down from the top right corner of the screen (or all over the top, depending on the control mode). In the Bluetooth unit, you will see a list of newly connected or active devices. Long tapping on the device name or tapping the arrow next to it will open the context menu.

The menu that opens often has a disable or delete profile button. However, it is worth noting that the control panel functionality may be limited in older versions of Android or on stripped-down versions of the shell. If there is no "Forget" button, the system will only suggest breaking the current connection, but will not delete the device from memory completely.

Using the notification curtain is effective for temporary communication break, but to completely clean up the history, it is better to still refer to the full settings menu. This will eliminate the likelihood that the phone will try to automatically reconnect the next time the headset is turned on.

Disposal problems and methods of their solution

Sometimes users are faced with a situation where the button "Unpair" is inactive, gray or completely absent, and it also happens that after removal, the device appears in the list again after a few seconds, this indicates a system failure or a conflict of processes in the background.

One of the common reasons is that the Bluetooth service freezes, in which case a simple smartphone reboot helps. If the problem persists, clear the cache of the Bluetooth system application. To do this, go to Settings → Applications → All applications, find in the list “Bluetooth” (may need to enable the display of system processes) and select “Clean data”.

⚠️ Warning: Clearing the Bluetooth system application data will delete all saved profiles at once, you will lose lists of all devices ever connected, and they will have to be paired again. Use this method only if you want to remove a particular device that is not removed in the standard way and you are ready to reconfigure the rest.

Another reason for the “resurrection” of remote devices may be synchronization through the Xiaomi cloud account. If you have other devices of the brand (tablet, TV, other phone) with enabled synchronization, the profile can be restored automatically. Check the settings of Mi Cloud and disable Bluetooth data synchronization if this option is available in your version of the software.

Removal via Engineering Menu and ADB (for Advanced)

For users who are not afraid of command line and system settings, there are deeper management methods. The engineering menu allows you to test communication modules, but access to it on global firmware is often limited. However, you can use USB debugging and the ADB tool (Android Debug Bridge) to force the removal of profiles.

To do this, activate the developer mode. Go to Settings → About the phone and quickly press 7 times on the build number (MIUI Version). Then in advanced settings, turn on “Debugging on USB.” Once you connect the phone to your computer, you can send commands to control the Bluetooth stack.

adb shell am broadcast -a android.bluetooth.adapter.action.DISABLE


adb shell am broadcast -a android.bluetooth.adapter.action.ENABLE

These commands force the reboot of the Bluetooth module, which often helps to “reset” the hung states of devices that are not removed through the interface. MAC-addresses require root rights and editing of system files of the Bluetooth database, which is not recommended without proper qualification, as you can disrupt the system.

Use of the ADB-It's safe to use commands if you follow instructions, but it's safe to interfere with system databases (/data/misc/bluetooth/) Without a backup, Bluetooth could stop turning on altogether, which would only help with a full reset to factory settings (Hard Reset).

Features of working with Xiaomi Wear and smart watches

Xiaomi smartwatches and fitness bracelets require a special approach. Often they are not deleted simply through the Bluetooth menu, as they are associated with the Mi Fitness app (formerly Zepp Life).If you try to remove the bracelet only through Bluetooth settings, the application can automatically restore the connection or give a synchronization error.

The correct algorithm of actions in this case looks different. First, you need to open the application that controls the clock, find the device in the list and choose Unplug or Delete the device. Only after the disconnect is confirmed in the application, you can go to the Bluetooth settings and delete the profile from there if it remains.

• ⌚ Open the Mi Fitness or Zepp Life app on your smartphone.
• 📲 Go to the device profile (usually the “Profile” or “Device” tab»).
• 🗑️ Click "Untie the device" and confirm the action.
• 🔧 Go to your phone’s Bluetooth settings and make sure the device is gone.

Ignoring this rule leads to the watch constantly trying to connect to the phone, discharging in a matter of hours, and there may be errors when trying to connect the watch to a new phone, as the old profile will block the new pairing.

💡

If you sell a smartwatch, be sure to untie it from your Mi Account account in the app, otherwise the new owner will not be able to use it because of protection against theft (Activation Lock).

It’s also worth remembering that some watches have a limited pairing memory buffer.If you change phones frequently but don’t delete old profiles from the watch itself (via resetting the watch settings), they may stop seeing new devices.
