How to completely clean Bluetooth on Xiaomi: Reset, Device Removal and Error Fixing

The Bluetooth module on Xiaomi smartphones eventually starts to malfunction: devices do not connect, the sound is interrupted, and garbage accumulates in the list of stored gadgets. The reasons lie in accumulated cache, profile conflicts and outdated MIUI data. Cleaning Bluetooth on Redmi, POCO or Xiaomi 13/14 requires a systematic approach - from simple removal of devices to a complete reset of the module.

In this article, you will find 5 proven Bluetooth cleanup methods, including hidden developer and ADB team settings. We will discuss how to remove “invisible” devices, reset cache without losing data and restore stable connection to headphones, speakers or fitness bracelets. Instructions are relevant for MIUI 12-14 and the new HyperOS, and take into account the features of Qualcomm and Mediatek chips.

Why is Bluetooth on Xiaomi starting to fail?

Bluetooth problems rarely come on suddenly, usually preceded by months of accumulated system debris, and these are the main reasons for the instability:

• 📱 Cache of the module overflowed: MIUI It stores data about every device you connect, even if you deleted it long ago, and over time, it leads to conflicts.
• 🔄 Residual profiles: When you quickly connect / disable gadgets (for example, headphones), “broken” profiles are created A2DP or AVRCP.
• 🔋 Energy saving: Adaptive battery function in MIUI Can forcibly turn off Bluetooth backgrounds in the background.
• 🛠️ Firmware errors: In some versions MIUI (for example, MIUI 13.0.4 for Redmi Note 10) was a bug with a constant reboot of the module.

Symptoms of “cluttered” Bluetooth:

• 🎧 Headphones are connected, but the sound is delayed or bursts.
