Xiaomi Redmi Watch 4

The Xiaomi Redmi Watch 4 launched globally in January 2024 at approximately $122, bringing a large-screen, feature-rich smartwatch experience to the budget tier. The standout feature is its 1.97-inch AMOLED display with 450x390 resolution and 600 nits brightness, one of the largest screens available in its price category. The aluminum alloy case measures 47.5x41.1x10.5mm and weighs 31.5g without strap, keeping the watch lightweight despite its expansive display. Xiaomi HyperOS powers the interface with a clean health dashboard and companion app. Core tracking features include optical heart rate monitoring, SpO2 blood oxygen, sleep stage analysis, stress monitoring, and step counting. GPS covers outdoor activities using GPS, GLONASS, Galileo, and BeiDou satellite systems. With 150-plus sport modes and an impressive 20-day battery life from the 470 mAh cell, the watch outperforms many pricier alternatives on pure endurance. Bluetooth calling enables hands-free wrist-based call management, and 5ATM water resistance covers swimming and water sports. For budget-conscious buyers who want a visually striking, large-format smartwatch with long battery life and comprehensive tracking, the Redmi Watch 4 delivers exceptional value. It is best suited to casual fitness users and step-counter shoppers who want maximum display size and battery duration at a sub-$125 price, without requiring premium health sensors or a full app ecosystem. The HyperOS platform is smooth for daily use, and the companion Xiaomi app provides accessible health trend visualization on both Android and iOS.
