I've mentioned it morethanonce, Xiaomi's branding and naming scheme is a complete and utter mess. A recent announcement made by Xiaomi is the first step, with hopefully many more to soon follow, in the right direction: the Mi branding on smartphones, computing devices, smart home products, and other products, is dead. Their reasoning is unification, simplification, and brand recognition.
Xiaomi's smartphones and smart home devices and no longer just inferior cheap alternatives to the more prestigious brands. In many cases, their features are equal to, if not better, than more expensive, but otherwise comparable, devices. This has obviously impressed customers, as Xiaomi has recently risen to become the second most popular smartphone brand in the world. It makes sense then to put their brand name, and not Mi, front and centre. The first Xiaomi branded smartphone will be the China-only Xiaomi MIX 4.
