Why You Should Remove Old Devices from Bluetooth
Every time you connect a gadget over Bluetooth (like the Redmi Buds 3 or Mi Band 6), the smartphone stores its data in memory. Over time, this list grows, which can lead to:

- π Connection conflicts β if there is a device with the same name (e.g. two Mi Smart Bands) on the list, the phone may confuse them.
- π« Pairing errors β some devices (especially budget headphones) do not connect if the smartphone memory remains data from the previous unsuccessful attempt.
- π± Problems after the update MIUI β New firmware versions sometimes reset Bluetooth settings, but older devices remain on the list as "unavailable".
In addition, some versions of MIUI (e.g. 12.5) have a limit on the number of Bluetooth devices saved, about 20. Once this threshold is exceeded, new gadgets may not be added or connected with errors, and regular cleaning of the list helps to avoid such situations.
β οΈ Note: Removing the device from Bluetooth does not erase it from the memory of the gadget itself (for example, headphones).To completely reset the pairing, you may need to reset the settings on the device itself (the instruction is usually in its manual).
