What Xiaomi Watches Are Compatible with the Redmi Note 10S?
Before connecting, it’s important to make sure your watch model is supported by a phone.The Redmi Note 10S runs on MIUI (usually version 12.5 and higher) and supports most Xiaomi smart devices, but there are nuances:
- 📌 Mi Band Series 3-8 – Full compatibility, all features available through the Mi Fitness app (formerly Mi Fit).
- ⌚ Xiaomi Watch S1/S2 Watch Color 2 — Require the latest version of the application and updated firmware of the phone.
- 🏃 Mi Smart Band Pro – Supported but some features (e.g., Mi Smart Band Pro, GPS) They may work in an unstable manner on custom firmware.
- ⚠️ Outdated models (such as the Mi Band) 1/2) — not officially supported MIUI 12.5+.
