Xiaomi has done it again—introducing the Watch S4, a feature-packed smartwatch that blends style, performance, and affordability.
With a smaller, more refined design, upgraded health tracking, and impressive battery life, this wearable is making waves in the crowded smartwatch market. But does it live up to the hype? Let’s break down everything you need to know about the Xiaomi Watch S4.

Design and Display A Modern and Compact Wearable
The Xiaomi Watch S4 takes a step away from bulky smartwatches with a slimmer, lighter, and more elegant design. The 1.43-inch AMOLED display is vibrant, sharp, and easy to read even under direct sunlight. With a 60Hz refresh rate, animations and swipes feel smooth, enhancing the overall user experience.
The aluminum alloy frame gives it a premium look, while the fluoroelastomer strap ensures comfort for all-day wear. Whether you’re hitting the gym or heading to a business meeting, the Watch S4 fits seamlessly into any lifestyle.
Performance and Software Smooth and Responsive
Powered by Xiaomi’s new in-house wearable chipset, the Watch S4 delivers snappy performance with minimal lag. Navigating menus, launching apps, and tracking workouts feel effortless. It runs on Xiaomi’s HyperOS for wearables, offering a clean, intuitive interface with customizable watch faces and widgets.
Unlike some competitors, the Watch S4 supports third-party apps, giving users more flexibility. Notifications, calls, and music controls work seamlessly when paired with an Android or iOS device.
Health and Fitness Tracking A Comprehensive Wellness Companion
Xiaomi has packed the Watch S4 with advanced health monitoring features, making it a great choice for fitness enthusiasts. The dual-frequency GPS ensures accurate tracking for runs, hikes, and cycling routes. Heart rate monitoring, SpO2 tracking, and sleep analysis are all precise and reliable.
New to this model is skin temperature sensing, adding another layer of health insights. The watch also includes women’s health tracking and stress monitoring, making it a well-rounded wellness device.
Battery Life Long-Lasting and Efficient
One of the biggest upgrades in the Watch S4 is its improved battery life. With typical usage, it lasts up to 10 days on a single charge—far better than many premium smartwatches. If you enable battery saver mode, you can stretch that to two weeks.
Charging is quick thanks to magnetic wireless charging, getting you from 0 to 50% in just about 30 minutes. No more worrying about running out of juice mid-day.
Smart Features More Than Just a Fitness Tracker
Beyond health tracking, the Watch S4 shines as a smart companion. It supports NFC for contactless payments (via Mi Pay), voice assistants, and even Bluetooth calling if you don’t want to pull out your phone. The built-in speaker and mic are clear, making it handy for quick calls.
The watch also stores music locally, so you can leave your phone behind during workouts. With 5ATM water resistance, it’s safe for swimming and rainy runs.
