How to remove your Bluetooth device from Xiaomi Redmi Note 9

Modern smartphones like the Xiaomi Redmi Note 9 accumulate a huge number of connections during active use. Wireless headphones, fitness bracelets, car radios and smart watches all leave a mark on the history of system connections. Over time, this list becomes cumbersome, which can cause communication module failures or simply interfere with the orientation of the settings. Deleting the device from the list is not only a way to put things in order, but also a necessary action when selling a gadget or fixing problems with synchronization.

With MIUI, the operating system on which Redmi's interface is based, Bluetooth connection management has its nuances. Users often confuse a simple disconnect with a complete deletion of the profile of the gadget. This leads to the phone continuing to "see" the forgotten device and try to connect to it automatically, using up battery power. In this article, we will discuss in detail how to properly clean the list of conjugated devices and what to do if the system behaves incorrectly.

Sometimes standard methods don't work because of software errors or data caching. In these cases, a deeper approach is required, including resetting network settings or using an engineering menu. Understanding how the Xiaomi shell pairing protocol works will help you avoid typical errors. We'll look at all the steps from standard uninstallation through menus to forced disconnection.

Basic method of removal through Bluetooth settings

The simplest and most common method, which is good for 95% of the time, is to use a standard settings menu. You don't need superuser rights or third-party utilities. You just open the Settings app on your Redmi Note 9 and go to the wireless connection section, and it shows all the gadgets that have ever been successfully paired with your phone.

Find the device you want to use. Usually, next to the name, you'll see the connection status or gadget icon (earphones, watches, car) and click on the name or the arrow to the right of it to reveal the additional menu. This is where the disconnect feature is hidden. In some versions of MIUI, you'll need to press and hold your finger on the gadget's name to invoke the context menu.

⚠️ Attention: Once you press the delete button, the system can request a confirmation of action, which is protection against the accidental erasure of important profiles, such as car radios, the settings of which are difficult to reset.

In the window that opens, you will see several options, including “Disable” or “Delete”; select “Delete” (sometimes designated as “Forget the device”), and then the encryption keys will be erased from the phone’s memory, and the gadget will disappear from the list of available ones. If you want to connect it again, the mating procedure will have to be repeated, introducing it. PIN-code or confirming the matching of the numbers on both screens.

Working with a list of previously connected devices

Xiaomi's interface sometimes hides the details of the connection by grouping them together or hiding them in a submenu. If you don't see the delete button right away, look at the gear icon next to the device name. Clicking on this symbol opens a page of the properties of a particular gadget. MAC-address, protocol version and battery level (if the gadget supports telemetry transmission).

The same menu often has an Auto Connection switch. If your goal is not to permanently delete the device, but simply to prevent automatic communication when it appears in range, just turn off this option. However, to completely clean the history, you need to find a button with a garbage bin or text "Unpair." On the Redmi Note 9, this interface element is usually located at the bottom of the screen or in the upper right corner.

It’s worth considering that some system apps, such as Mi Wear or Mi Fit, may have their own lists of devices that duplicate system Bluetooth. Removing a gadget in your phone’s settings doesn’t always remove it from your companion app. So if you sell a fitness bracelet or transfer it to another person, be sure to check the settings inside the relevant app to untie the device from your Mi Account.

Problem Solving: When the device is not removed

Xiaomi users sometimes face a situation where the Remove button is inactive (gray) or the process freezes. This can be caused by a background process that holds the connection, or a software failure in the Bluetooth service. In such cases, simply pressing the buttons will not help. You need to force the services responsible for wireless communication, or reboot the module itself.

The first step when an error occurs is to try to reboot your smartphone. This trivial action often clears the temporary cache and ends the hanging processes. If the reboot did not help, go to Settings → Applications → All Apps. Find in the list of “Bluetooth” or “Bluetooth MIDI Service.” Go to the app properties and click “Stop” and then “Clean Data.” This action will reset all temporary service files, but will not delete the stored pairing passwords if they are stored in a secure area.

If neither method works, it may be deeper in the file system or firmware. In rare cases, switching the date and time on a smartphone helps, which knocks down session timers, after which deletion becomes possible. However, this is an extreme measure, and after successfully removing the time setting, you should return to automatic mode.

Resetting network settings as a radical solution

When standard methods are exhausted and the bug device continues to hang on the list or interfere with new gadgets, you have to resort to resetting your network settings, which is safer than completely resetting your phone to factory settings, because it does not affect your personal files, photos or contacts. However, all stored Wi-Fi passwords and Bluetooth pairings will be permanently deleted.

To do this, go to the Settings menu on Redmi Note 9 → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you of the consequences. Confirm the action by entering the unlock password or pattern lock. After that, the phone will restart the network modules, and the list of Bluetooth devices will become completely empty, as when you first turn on the device.

⚠️ Note: After resetting your network settings, you will have to re-enter passwords from all Wi-Fi networks and re-connect all Bluetooth gadgets (earbuds, watches, speakers.

This method is especially effective if you have common connection problems: the phone does not see new devices, communication is constantly interrupted or data rate is extremely low. Network reset clears the configuration files of wireless drivers, eliminating software conflicts that have accumulated during the use of the smartphone.

Using Developer Mode to Manage Bluetooth

For advanced users who want to gain full control of the communication module, MIUI has a hidden developer menu. To activate it, you need to quickly click seven times on the build number in the About Phone section. Once you become a developer, a new option will appear in the settings menu "Additional" or "Extended settings", and inside - "Developers".

In this section, you can find the Bluetooth Version option, where you can switch protocols (for example, force Bluetooth 5.0 or older versions for compatibility), and here you can find the "Deactivate Absolute Volume Level" feature, which solves problems with quiet sound in headphones. Although there is no direct list of devices here, resetting the Bluetooth stack through this menu can help "unt" the hung connections.

One useful feature for cleaning is “Show all AVRCP devices.” Turning on this option allows you to see in the list of connections even those gadgets that are usually hidden by the system as multimedia controllers. This helps to find and remove “ghost” devices that occupy slots in the list and interfere with normal operation. Be careful when changing the settings in this section, as incorrect settings can lead to unsettled communication.

💡

Tip: Before entering developer mode, take a screenshot of your current Bluetooth settings, which will help you return the initial values if the connection stops working correctly after the experiments.

Cache cleaning and system maintenance

The accumulation of junk files can slow down not only storage, but also system services. Xiaomi’s standard Security app has a built-in cleaning tool, but it doesn’t always affect Bluetooth deep logs. You can use the Advanced Cleanup feature in the same app to select System Cache.

If you suspect that a particular application (such as a navigator or music player) is blocking the device from being deleted, try clearing its cache separately. Go to Settings → Apps → All apps, find suspicious software, and select Clear → Clear Cache. Don’t confuse it with Clear Data, as this will remove your personal settings inside that application.

Regular maintenance helps prevent future errors. Try not to keep dozens of old profiles of devices you haven't used in a long time in your phone's memory. The fewer entries in the pairing table, the faster the Redmi Note 9 scans the air and connects to the right gadgets. This is especially important for smart home owners, where the number of connected devices can number in the tens.

💡

Regularly cleaning the list of Bluetooth devices not only frees up memory, but also increases the stability of the connection with active gadgets, eliminating addressing conflicts.
