However, even with such a simple gadget, the first launch can raise questions — especially if you have never used a smart bracelet before. This article will help you understand how to properly turn on the Mi Band 4, connect it to a smartphone and avoid typical mistakes.

It’s important to understand that the Mi Band 4 doesn’t have a traditional power button — it’s activated automatically after charging or when interacting with the touch screen.
