How to Remove Bluetooth Connections on Xiaomi: A Complete Guide to All Models

Xiaomi, Redmi and POCO automatically store all Bluetooth-connected devices, from headphones and speakers to smartwatches and in-car multimedia systems. Over time, the list of associated gadgets grows, which can lead to connection conflicts, slowing down the search for new devices, or even security leaks. For example, if you have ever connected to a public speaker in a cafe or rented car, these devices will remain in your phone’s memory and can automatically connect the next time you find them.

In this article, you will find step-by-step instructions for removing Bluetooth connections on all current versions of MIUI (12 to 14), including hidden settings for power users. We will also discuss why some devices are not removed in the standard way, how to reset Bluetooth settings to factory ones, and what to do if the gadget refuses to connect again after removal.

Why You Should Remove Old Bluetooth Connections

Every Bluetooth device stored takes up space in the system memory and can affect the performance of the wireless module. Here are the key reasons why it is worth cleaning the list regularly:

• 📱 Automatic connections: Some devices (such as car radios) try to connect automatically, even if you don’t want to.

On Xiaomi smartphones with MIUI 14 and later, the list of Bluetooth devices is stored in encrypted form, but even this does not guarantee complete protection against data leaks when physically accessing the phone. For example, if you sell or transfer a phone, the new owner will be able to see all the gadgets ever connected, if you do not perform a reset.
