Stylish Accessory

The 41 mm version of the Xiaomi Watch S4 was originally designed as a sophisticated and stylish accessory primarily aimed at a female audience. The device looks elegant and neat: the thin 9.5 mm case is connected to the straps through metal fastenings, and the compact 1.32-inch screen makes the watch visually light and almost unnoticeable when worn for extended periods. Besides a wide choice of colors — from classic to bright and delicate — the manufacturer offers three types of straps: a practical silicone strap for sports, a formal leather strap, and a refined Milanese bracelet. The latter is used in the premium Sunset Gold version, adorned with a small lab-grown diamond on the rotating crown. However, it's worth noting that this modification is not available in all countries and stores.

In practical terms, the model also delivers: the protective screen glass is resistant to scratches and abrasions, and its 5 ATM water resistance rating allows you to use the watch during rain, swimming, or hand washing with ease.

Assistant During Workouts and Emergencies

As for functionality, the watch does not strive to impress with innovations but offers everything necessary for monitoring health, physical activity, and everyday comfort. The device displays incoming notifications and calls, and also allows responding to them. Contactless payment is supported, though NFC functionality depends on the region. The battery life lasts up to 4 days in standard mode or about 3 days with active usage and the Always-on Display feature enabled.

For sports activities, more than 150 training modes are provided, and five satellite navigation systems ensure high accuracy in outdoor activity tracking. The watch measures heart rate, blood oxygen level, body temperature, sleep quality, and stress level. Based on this data, the device helps maintain a female calendar. Among the safety features is a loud siren to deter attackers and triple pressing a button to make an emergency call to a chosen contact. There's also an option to share your location in critical situations. When skiing, the watch can detect falls: if the user does not respond within 60 seconds, the device automatically initiates a call to a contact person.
