The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular trackers even years after its release, thanks to its balance of price, functionality and reliability. However, many users use it only 30% of the options: limited to pedometer and time, while the right setup allows it to become a full-fledged assistant for health, sports and even smart home management.
In this article, we will examine not only the basic steps (connection, synchronization), but also the hidden functions that the manufacturer does not advertise, from customizing dials to fine-tuning notifications. We will focus on typical errors that cause the bracelet to quickly discharge or lose communication with the smartphone. All instructions are relevant for firmware 1.0.9.54 and later (2026).

- ๐ Internet connection: to download firmware and weather data will require stable Wi-Fi or mobile Internet (3G/4G).
Also check the package: the box should contain the bracelet itself, the charging cable (with a magnetic socket) and a brief instruction. If there is no cable, use only the original or certified counterpart. Cheap charging can damage the contacts of the bracelet.
