How to connect the fitness bracelet Xiaomi Mi Band 4 to the smartphone: instructions with pictures and life hacks

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular trackers even years after its release, thanks to the balance of price, functionality and reliability. However, beginners often have difficulties with the first connection: the application does not see the device, the bracelet does not sync, the data is not updated. This article will help avoid typical errors and configure the Mi Band 4 from scratch, including hidden functions that the official instructions do not say.

We'll look at two scenarios: connecting to Android (including Xiaomi, Samsung, Honor) and iPhone (iOS 12+), and what to do if the bracelet is not determined by the system. Separately, we'll focus on setting up notifications, pedometer and pulsemeter, the most popular features. If you bought a used device or reset it to factory settings, here you will find a solution.

If you're connecting the bracelet for the first time, remove it from the package and remove the protective film from the charging contacts. The Mi Band 4 doesn't have a physical on button -- it activates automatically when you connect to the charger or when you sync it with your smartphone. Don't try to "plug" it on the screen -- it's useless until the first tether.
