Key Features & Major Redesigns
1. Large 1.97-Inch AMOLED Display
The Redmi Watch 4 introduces the largest screen in the series history. The 1.97-inch AMOLED display offers a 60Hz refresh rate that makes scrolling through notifications and apps incredibly smooth. With a peak brightness of 600 nits, it remains completely legible even under intense afternoon sunlight.
2. Premium Aluminum and Stainless Steel Case
Moving away from plastic builds, this generation upgrades to a high-strength aluminum alloy middle frame. It is completed by a precision-engineered stainless steel rotating crown on the side, allowing you to easily navigate menus, adjust settings, or return home with mechanical tactile feedback.
3. Extended 20-Day Battery Longevity
Equipped with an optimized 470 mAh battery, this watch eliminates daily charging anxiety. It delivers up to 20 days of runtime under typical operation, up to 30 days in long-battery mode, and up to 10 days when leveraging the interactive Always-On Display (AOD) functionality.
4. Independent Multi-System GNSS Tracking
Outdoor athletes can ditch their smartphones during training. The integrated multi-system GNSS chip accurately logs your running paths, walking routes, and cycling distances independently. It pairs with over 150 sports modes, ranging from indoor swimming to outdoor hiking.
Smart Bluetooth Calling & Health Tracking Hub
The device features an integrated speaker and microphone array that lets you answer and conduct Bluetooth phone calls directly from your wrist when paired with your smartphone.
On the wellness side, an upgraded 4-channel PPG sensor module monitors your heart rate, sleep quality, stress levels, and blood oxygen saturation (SpO2) around the clock. All your recorded statistics sync directly to the native Mi Fitness app on Android or iOS, letting you review your fitness trends over weeks and months in a beautifully structured dashboard.
