#Xiaomi Watch S4 Review

Alongside the new Xiaomi 15T Series, the company also launched the 41mm Xiaomi Watch S4. This one’s the smaller sibling of the OG Xiaomi Watch S4 that has been released locally in March 2025. Health Features and Fitness Tracking Despite the elegant look, the Xiaomi Watch S4 packs pretty much all the nifty health and fitness tracking features. Software and User Experience Speaking of connectivity, you can expect that the Xiaomi Watch S4 is compatible with any smartphone through Xiaomi’s app called Mi Fitness. I have the POCO F6 Pro as my daily driver, and it supports Xiaomi Interconnectivity offering a bit more seamless integration with the Xiaomi Watch S4. Another issue that I have with the Watch S4, in fact for all Xiaomi smartwatches, is the app selection is still limited to its first-party apps like Alarms, Weather, Tasks through Mi Notes, and the Calendar. I’d like to have a pomodoro timer on my watch, but it appears I still can’t do that with the Xiaomi Watch S4. Lastly, despite the Xiaomi Interconnectivity thing, I can’t reply to chats or text messages directly from the watch, which is something I hope Xiaomi can improve upon.
