We’ve also included a detailed comparison table for a clear overview.
Design and Display: A Step Up in Style
The Redmi Watch 3, globally launched on December 27, 2022, boasts a compact, lightweight rectangular design (42.58 x 36.56 x 9.99 mm, 31 g without strap), perfect for smaller wrists. Its 1.75-inch AMOLED display (450 x 390 pixels) delivers vibrant colors and sharp visuals, housed in a practical plastic frame that keeps costs down.
In contrast, the Redmi Watch 4, unveiled globally on January 15, 2024, takes a bolder approach with a larger, more polished build (47.58 x 41.12 x 10.5 mm, 31.5 g). Its 1.97-inch AMOLED screen features a 60Hz refresh rate for smoother navigation, paired with an aluminum alloy frame and a stainless steel rotating crown for a premium feel.
Verdict: The Watch 3 suits those who prefer a subtle, compact design, while the Watch 4 appeals to users wanting a bigger, more stylish display.
Performance and Software: Modern Tech Edge
The Redmi Watch 3 runs on a proprietary OS tailored for basic tasks, equipped with sensors like an accelerometer, gyroscope, heart rate monitor, SpO2, and geomagnetic sensor. It supports over 120 sports modes and offers reliable Bluetooth 5.2 connectivity, alongside multi-system GPS (GPS, GLONASS, Galileo, Beidou).
The Redmi Watch 4 steps up with HyperOS, enhancing the interface and customization with over 200 watch faces. Its 4-channel PPG sensor improves health tracking accuracy by 10% compared to its predecessor, and it adds over 150 sports modes with voice guidance. Connectivity upgrades to Bluetooth 5.3, and it includes NFC for contactless payments (select markets), while retaining full GNSS support.
Verdict: The Watch 4 shines with advanced software and precision, though the Watch 3 remains solid for basic needs.
Battery Life: Power That Lasts
With a 289 mAh battery, the Redmi Watch 3 offers up to 12 days of typical use or 7 days with heavy usage, charging fully in about an hour. The Redmi Watch 4, however, packs a 470 mAh battery, stretching its life to 20 days under typical conditions, 10 days with always-on display (AOD), or up to 30 days in power-saving mode.
