If your phone is older, the Smart Band 8 can connect, but some features (for example, fast data synchronization) will work unstable.

⚠️ Note: Some smartphones Huawei and Honor with EMUI 12+ Mi Fitness can be blocked by the system as "unoptimized." To avoid problems, add the application to the list of allowed battery settings before connecting.

Installation and configuration of the Mi Fitness application

The official Xiaomi Smart Band 8 management app is called Mi Fitness (formerly Mi Fit) and can be downloaded for free from Google Play or the App Store. Importantly, use only official sources, as third-party APKs may contain malicious code or outdated versions of the bracelet firmware.

After installation, follow the following steps:

1. Open the app and select the language (we recommend Russian, as other localizations may not have translations for some features).
