A More Compact Design with a Larger Display
Despite moving to a slightly smaller 46 mm case size, Xiaomi has managed to increase the screen real estate. The Watch S5 features a 1.48-inch AMOLED panel, surpassing the 1.43-inch display found on the previous generation.
The display is the centerpiece of the device, offering a crisp resolution of 480 x 480 pixels and a pixel density of 323 PPI. Most notably, it achieves a standard full-panel brightness of 1,500 nits, with the ability to reach a staggering 2,500 nits peak brightness under specific lighting conditions, ensuring perfect legibility even in direct sunlight.
Enhanced Health Tracking and HyperOS 3
Under the hood, the Watch S5 is powered by Xiaomi’s latest software, HyperOS 3. The brand has placed a heavy emphasis on data precision, claiming a 98.4% accuracy rate for heart rate monitoring thanks to a redesigned sensor array.
Beyond heart rate, the device features upgraded algorithms for sleep tracking and more precise GPS positioning. These refinements aim to position the Watch S5 not just as a fashion statement, but as a highly reliable tool for fitness enthusiasts and health-conscious users.
Long-Lasting Battery and Specialized Editions
Battery life remains a strong suit for Xiaomi wearables. The Watch S5 is equipped with an 815 mAh battery that can last up to 21 days when used in power-saving mode. For those who prefer the convenience of the Always-On Display (AOD), the watch still manages a respectable 9 days of use on a single charge.
The smartwatch is available in several distinct styles:
-
Standard Editions: Available in Black and Silver finishes.
-
Premium Editions: Forged Carbon and Midnight Blue versions for a more sophisticated look.
-
Connectivity: A dedicated eSIM version is also available for those requiring independent cellular connectivity.
Pricing and Availability
Currently, the Xiaomi Watch S5 is exclusive to the Chinese market. The standard Black and Silver models are priced at approximately CNY 1,099 (~$159). The more premium Forged Carbon, Midnight Blue, and eSIM variants retail for CNY 1,299 (~$189). While these competitive prices make it an attractive option in the luxury smartwatch segment, Xiaomi has yet to confirm a timeline for a global release.
