Modern Xiaomi, Redmi and POCO smartphones are equipped with advanced wireless communication modules that allow you to instantly connect to headphones, speakers, fitness bracelets and automotive systems. However, pairing technologies do not always work perfectly, and users often face a situation where the gadget stops interacting with the phone correctly or refuses to connect at all. In such cases, the standard and most effective solution is the procedure of “forgetting” the device, which completely clears the history of previous connections.
Many Android smartphone owners mistakenly believe that simply turning off Bluetooth or breaking the connection is enough to fix the bugs. In fact, the memory of the MIUI or HyperOS operating system stores encryption keys and configuration files that can conflict when you try again, which is why you need to perform a complete reset of the pairing profile, which often returns the stability of the wireless interface.
In this guide, we will take a detailed look at all the available ways to delete Bluetooth profiles, break down the hidden nuances of Android security and offer solutions for complex cases where the device is not removed by standard methods.
Why You Should Remove Old Bluetooth Connections
The accumulation of a list of previously connected devices can negatively affect the speed of the smartphone. The operating system periodically scans the air for known gadgets, trying to establish a connection with those that are in range. If there are many profiles stored in memory, including those that you have not used for a long time, this puts an extra load on the communication module and the processor.
Often the problem lies in conflicting protocol versions or corrupted cache files. For example, after a Xiaomi firmware update, the Bluetooth algorithms can change, and the old authorization keys are no longer properly processed by the system, as a result, the phone can “see” the device but refuse to connect, giving a pairing error or endlessly rotating the boot indicator.
There is another important aspect to safety: If you lose your headphones or sell a car with a stored phone profile, unauthorized persons could theoretically try to use a trusted connection. Deleting old profiles ensures that access to media or phone data via Bluetooth is left only to authorized and up-to-date devices.

- 🚀 Accelerating the process of searching and connecting to the main gadgets.
- 🛡️ Improving the security of personal data by cleaning up the list of trusted devices.
- 🔋 Reduced energy consumption by reducing background connection attempts.
⚠️ Before removing the device, make sure it is not currently in use for mission-critical functions such as navigating in the car or transmitting audio during a call so as not to interrupt an important process.
Standard Removal Procedure Through Settings
The easiest and safest way to forget a Bluetooth device on Xiaomi smartphones is to use a built-in settings interface, which works on all current versions of the shell, including MIUI 12, 13, 14 and the new HyperOS. The procedure is intuitive, but has its own features of the layout of menu elements depending on the version of Android.
To start, you need to go to the main settings menu. Find the wireless connection section. Depending on the design theme and the system version, it can be simply called "Bluetooth" or be located within the Connection and Sharing category. Once you turn on the module, you will see a list of available and already connected devices.
Find the device you want to use, and usually next to the name of the gadget, you'll see an icon of the device type (earphones, watches, car) and click on the device name or the arrow to the right of the device to reveal the additional menu, and that's where the feature is hidden.
☑️ Device removal algorithm
In the window that opens, you will see several options, such as the connection switch, charge level (if supported), and delete button. Click on "Unpatch" or "Forget device." The system will request confirmation of the action, as it is irreversible for the current session. Once confirmed, the device will disappear from the list, and the full procedure (patch) will be reused.
Managing devices through a quick access panel
For those who value time, there is an alternative, faster path to managing connections, although it has limited functionality compared to full settings. You can quickly break the connection through the notification panel, but the most common way to completely delete the profile is to go to a deep menu.
Swipe down from top to bottom to open the control center. On the newer versions of HyperOS and MIUI, this interface is heavily redesigned. Find the Bluetooth icon and click on it to turn the module on or off. However, to see the list, you need to press and hold your finger on the Bluetooth icon or click on the arrow next to it (depending on the topic).
A pop-up with a list of connected devices will open, often showing only active or recently used gadgets, click on the gear icon or arrow next to the device name. If this menu has an option to "Unpair", use it. If there is no such button, the system will redirect you to the full settings menu described in the previous section.
It is important to note that on some Redmi and POCO models with a simplified shell, the interface may differ, in which case long pressing of the Bluetooth icon in the curtain is the only quick way to get to the desired menu, bypassing the search for the setting icon on the desktop.
Hidden functions of Bluetooth menu
Deletion problems: when the button is inactive
Users may encounter a situation where a device appears in the list, but the Forget or Unpair button is inactive (sererated) or absent.This is a common problem that often involves the device being actively used by system services or third-party applications.
Most often, health monitoring applications such as Mi Fitness, Zepp Life or Google Fit are blocked, and these programs constantly poll fitness bands and watches, keeping the connection active and preventing the system from forcibly breaking it through a standard menu, and car systems that automatically restore communication when the engine starts.
To solve the problem, you must first close the application that controls the device. Go to the menu of running applications and close the activity tracker. If this does not help, try temporarily disabling the Bluetooth device itself (turn off the headphones or bracelet) to break the physical communication channel, and then repeat the deletion procedure on the phone.
| Type of device | Probable reason for blocking | Decision |
|---|---|---|
| Fitness bracelet | Active synchronization in the background | Close the application Mi Fitness/Zepp |
| Car | Autoconnection with the engine started | Turn off Bluetooth in the car or shut down the car |
| Smart watches | System notifications | Disable the clock through a companion app |
| TWS headphones | The process of audio transmission freezes | Put the headphones in the case and close the lid |
⚠️ Note: If the device belongs to the category "Input devices" (keyboard, mouse) and is actively in use at the moment, it may not be possible to remove it through the menu on the screen due to loss of control. OTG.
Resetting network settings as a radical method
If standard methods don't work, the device doesn't get deleted, the list freezes or the phone doesn't see any gadgets at all, a deeper approach will be needed. Network resets bring all Wi-Fi, Bluetooth and mobile data settings back to factory values. This won't delete your personal files, photos or contacts, but will clear all network configurations.
To do this, go to Settings → Connection & Sharing → Reset Wi-Fi, Mobile Networks, and Bluetooth. In some versions of MIUI, this path may look like Settings → Advanced Settings → Reset and Reset → Network Settings Reset. The system will alert you that all saved Wi-Fi and Bluetooth passwords will be deleted.
Once confirmed, the phone will reboot network modules, which is especially effective when there is “digital junk” on the pairing list — devices that no longer exist or have been sold but continue to hang in the system, causing errors, and it also helps with crashes after a failed firmware update.
It’s important to understand that after this procedure, you’ll have to re-enter passwords from all Wi-Fi networks and all Bluetooth gadgets, so if you have complex corporate networks or multiple smart devices set up, make sure you have access to passwords.
💡
Before resetting your network settings, write down passwords from important Wi-Fi networks or make sure you remember them, as it will be impossible to recover them from the system after resetting.
Use of engineering menu and debugging
For advanced users who aren’t afraid to experiment, it’s possible to control the Bluetooth stack through a developer menu, which not only removes devices, but also resets the Bluetooth cache, which can be useful for deep system errors.
First, activate Developer Mode. Go to Settings → About Phone and quickly click 7 times on either MIUI Version or OS Version until the message “You’re a developer” appears. Then go back to the main settings menu, select “Additional” → “Developers”.
Inside the menu, find the Bluetooth-related section. The options “Enable HCI Bluetooth Reports” (for diagnostics) or “Reset Bluetooth settings” may be helpful here. In some cases, switching the Bluetooth MAP or AVRCP version helps if the device is not working properly after being removed and paired again.
adb shell pm clear com.android.bluetoothThis command, which is typed through a computer with an ADB installed (Android Debug Bridge), completely clears the Bluetooth application data on the phone, which is equivalent to reinstalling the system component of communication, and after you execute the command, the phone can restart, and the list of all devices will be completely cleared.
💡
Use of the ADB-commands are the most powerful way to clear the Bluetooth cache, but it requires a computer and basic command line skills.
