Managing wireless connections on Xiaomi smartphones and tablets often requires periodic cleaning and adjustment. The accumulation of old pairing profiles can lead to slowing down the communication module, automatically connecting to unnecessary gadgets or the inability to find new devices within range, especially when changing the headset, selling smartwatches or when there are software conflicts in the MIUI system and the new HyperOS.
The process of deleting (pair break) on Redmi and POCO devices may differ from the standard android algorithm due to the deep customization of the interface. The user needs to understand the difference between simply disabling and completely deleting the profile from the phone’s memory. In this article, we will discuss in detail all the nuances of managing the list of trusted devices, forced reset methods and how to solve typical errors.
Sometimes the system can "remember" the device even after it's physically destroyed or lost, while continuing to search for the signal and consume battery power. Cleaning the list is not just a cleanup, but an important procedure for optimizing power consumption. We'll look at the standard methods through the settings menu, as well as more advanced methods through the engineering menu and debugging.
Standard Removal Procedure Through Settings
The most common and safe way to remove unnecessary hardware from the smartphone memory is to use the standard operating system interface. The algorithm of actions is the same for most versions of the shells, but the location of the elements may vary slightly. First, you need to activate the wireless module itself, since in the off state the list may not be available for editing.
Go to your Xiaomi’s main settings menu and find the Bluetooth section. In modern firmware versions, it is often placed at the top of the list or inside the Connection and Sharing category. Once you log in, you’ll see the status switch and the list of gadgets available for connection, as well as the My Devices or Associated Devices section.
- 📱 Find in the list of “My devices” the name of the gadget that you want to remove.
- ⚙️ Click on the gear icon or arrow to the right of the device name to enter its properties.
- 🗑️ In the menu that opens, select the option “Cancel pairing” or “Forget device».
- ✅ Confirm the action in the pop-up dialog window.
Once you do this, the device profile is completely erased from the phone’s memory, and if you want to reconnect it, you’ll need to re-search and enter the confirmation code, ensuring that the phone doesn’t automatically try to connect to the forgotten gadget when it appears in sight.
💡
Completely deleting a profile ("Forget") is different from simply breaking a connection in that the phone stops "recognising" the device the next time it contacts.
Managing the list through the notification panel
For quick access to frequently used functions, the MIUI shell features a control panel called down by swipe, where you can not only turn the module on or off, but also move to managing specific connections, a method that is convenient when you need to quickly disconnect from the current headset, but it has its own limitations on functionality.
Press your finger on the Bluetooth icon in the notification curtain to get into the extended menu. Active connections are displayed here. If the device is active right now, you can click on it to break the connection. However, to completely remove it from memory, it is still better to click on the link “Other devices” or through the gear to the full list of settings.
⚠️ Attention: Quickly shutting down through the notification curtain often only breaks an active session of communication, but does not remove the device from the list of trusted.
In some versions of firmware, with a long press on the name of the active device, a contextual menu may appear in the curtain. If there is a "Cancel pairing" option there, you can use it. However, the curtain interface is often changed by developers, so you should not count on the presence of this feature - the classic settings menu remains the most reliable option.
Forced resetting and cleaning of service cache
There are situations where the device is not removed in the standard way, hangs in the status of "Connect..." or appears in the list, although it does not physically exist. In such cases, cleaning the data of the Bluetooth system service helps, this action is safe for personal files, but resets all the settings of the wireless module to the factory.
To do this, you'll need access to the application management menu. Go to Settings → Applications → All applications. In the upper right corner, click on three dots and select the Show System Processes option. This is a critical step, because without it, the desired component will be hidden from the user's eyes.
In the list that opens, look for an app called Bluetooth (or Bluetooth MIDI Service in some versions). Go inside and select Memory. Then click Clear and choose Clear or Delete.
☑️ Checklist for resetting Bluetooth module
Once the data is cleaned, the system will need to reboot, the next time it turns on, the list of associated devices will be completely empty, you will have to re-hide all the necessary gadgets, entering all the necessary gadgets. PIN-It's an effective way to solve software errors when the communication module is behaving incorrectly.
Using the Engineering Menu for Diagnostics
For advanced users who have experienced deep system errors, there is an access to the engineering menu, a hidden part of the system that is designed to test hardware components, and you can perform a deeper reset of the radio module settings than the standard interface allows.
To enter the menu, open the Phone app and dial ##6484##. The CIT menu will appear on the screen. Find a Bluetooth-related item (often simply called “Bluetooth” or “BT Test”) on the list. Data transfer and configuration reset tests can be available inside.
| Parameter | Description | Impact on data |
|---|---|---|
| Standard removal | Delete one profile through settings | Safely, removes only the selected device |
| Cleaning the application data | Reset Bluetooth service in settings | Removes ALL pairings, resets the module settings |
| Engineering test | Diagnostics of hardware through the CIT menu | Does not delete profiles, checks the performance of the chip |
| Full reset (Wipe) | Delete all data from the phone | Complete cleaning of your phone, including Bluetooth profiles |
Use the engineering menu requires caution. Don't change settings that you don't understand, because it can cause the radio to run in an unstable way. The main goal here is diagnostics: if tests show an error, the problem may be hardware, and software removal of the devices will not help.
What to do if the engineering menu is not opened?
Solving problems with “hanging” devices
A common problem with Xiaomi users is the inability to remove a device that is physically inaccessible (discharged, lost, or broken).The phone can endlessly try to restore the connection by blocking the interface or draining the battery.
Try the following algorithm: first turn on Bluetooth on your phone, then turn it off. Immediately after turning it off, quickly go to the list of devices and try to delete the problematic profile before the background services have time to start the auto-connection process. If that doesn't help, temporarily rename your device in Bluetooth settings - this sometimes resets the search cache.
- 🔄 Restart your smartphone in Safe Mode to eliminate the impact of third-party apps.
- 📡 Turn off geolocation as it is often used for scanning BLE-device.
- 🔋 Charge your smartphone as with low battery levels, the system can limit background cleaning processes.
If the ghost device is still on the list, check if it is part of the Mijia or Zepp Life ecosystem, and sometimes the profile is duplicated in the system Bluetooth and in the companion app, and the removal should be done first through the companion app, and then through the system settings.
⚠️ Warning: If the device is not removed and blocks the phone, it may be infected with a miner virus or part of malware.
Resetting network settings as a radical solution
When nothing works and the list of Bluetooth devices is not working properly, the last software method is to completely reset the network settings, which will affect not only Bluetooth, but also Wi-Fi and mobile Internet. All saved passwords from the networks will be deleted.
Find Connection and Sharing in your settings (or simply search for settings, type Reset) and select Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you of the consequences. Confirm the action by entering the screen unlock password.
Path to discharge:
Settings → Connection and Sharing → Reset Wi-Fi, Mob. Networks and BT → Reset SettingsOnce rebooted, your Xiaomi will have a clean list of wireless connections, guaranteed to remove any software bugs associated with the conflict profiles, you will have to re-enter your home Wi-Fi passwords and reconnect your watch, headphones and car stereo.
💡
Before resetting your network settings, take a photo of passwords from important Wi-Fi networks or make sure you remember them to avoid being left without internet access.
