Voice assistants on Xiaomi smartphones are often activated by accident – just press the Home button or say a key phrase, as the Google Assistant or Xiao AI appears on the screen. For many users, this feature is useless, annoying with constant pop-ups or even consumes up to 15% of battery power in the background (according to tests on the Redmi Note 11 with MIUI 13).
In this article, we will discuss all the current methods for different versions of MIUI (12 to 14), including hidden settings for Chinese firmware, where Xiao AI is integrated at the kernel level.
