How to check the Bluetooth version on Xiaomi phone: all the ways

Why it is important to know the version of Bluetooth in Xiaomi

The Bluetooth version of your Xiaomi smartphone directly affects data transfer speed, stability of connection to headphones, fitness bracelets and other devices. For example, Bluetooth 5.2 consumes 30% less power than Bluetooth 4.2, and supports simultaneous connection to two audio devices. And Bluetooth 5.0 has LE Audio technology, which improves the sound quality in wireless headphones.

If you notice that Redmi AirDots headphones or Mi Portable Speaker speakers have started to “brake” when playing music, or the Mi Band fitness bracelet constantly breaks the connection, the problem may lie in an outdated version of Bluetooth. Also, knowing the exact version will come in handy when buying new gadgets: not all smart watches or wireless headphones are compatible with old protocols.

In this article, we will discuss 5 proven ways to find out the Bluetooth version on any Xiaomi smartphone – from the budget Redmi to the flagship Xiaomi 14. At the end, you will find a table of compatibility of Bluetooth versions with popular devices of the Mi Home ecosystem.
