Unboxing and Design Details

The review unit arrived in the Jungle Green colorway. This version features a green strap made from a combination of fluororubber and nylon braided materials. The strap uses a standard 22mm size, making it easy to swap for another style if desired. Inside the box, the only accessory included is a two-pin magnetic charging puck, which is standard for Xiaomi smartwatches.

The Watch S5 features a 1.48-inch AMOLED display. The screen reaches up to 2,500 nits peak local brightness, ensuring visibility in various lighting conditions. The display is sharp and comes with several preloaded watch faces. Around the screen, the bezel includes a forged carbon element that adds a distinctive style. Both the bezel and the watch body are made from stainless steel, giving the device a solid and premium feel. The right side of the watch houses a crown and a shortcut button for easy navigation.

Features and Functionality

The Xiaomi Watch S5 runs on HyperOS 3. It does not offer the full range of features found on WearOS devices but covers essential functions. Users can access standard health and activity tracking features. The watch includes an onboard speaker and microphone, enabling voice calls. However, the international version lacks cellular connectivity and NFC capabilities.

Xiaomi emphasizes the Watch S5's battery life, claiming up to 21 days of use on a single charge. The full review will test these claims and provide detailed results on battery performance, display quality, and overall user experience.
