Why link Mi Band 4 to Xiaomi phone
Xiaomi’s Mi Band 4 fitness bracelet remains one of the most popular wearables years after its release, and its main advantage is its close integration with Xiaomi’s ecosystem, which is revealed only when connected to the brand’s smartphone correctly. Without pairing, the bracelet becomes a regular pedometer with an alarm clock, depriving it of key features such as call notifications, instant messenger messages, music monitoring, and detailed sleep analytics.
Xiaomi phone owners (Redmi, POCO, Mi) get an added bonus: the bracelet automatically syncs with the Mi Fit app (now Zepp Life), which simplifies configuration and expands the possibilities. For example, only when you connect to a Xiaomi smartphone, the function of unlocking your phone on the bracelet (subject to device support) becomes available. In this article, we will analyze all the stages of the connection – from preparation to solving typical errors relevant for 2026.
Preparation for connection: what to check before pairing
Before you start setting up, make sure that your bracelet and phone meet the minimum requirements. Mi Band 4 is compatible with smartphones on Android 5.0+ or iOS 10.0+, but for full work with Xiaomi devices, a firmware version at least MIUI 10 is recommended.

Pay special attention to permissions for the Zepp Life app (formerly Mi Fit). Without access to notifications, contacts and location, the bracelet will not be able to show incoming calls or messages. On Xiaomi phones, these settings are hidden in the Settings menu → Apps → Permissions Management → Autorun – turn on autorun for Zepp Life, otherwise sync will be interrupted.
