Redmi Watch 4 is a budget-friendly smartwatch from Xiaomi’s Redmi lineup (released late 2023/early 2024), known for its large vibrant display, exceptional battery life, and solid everyday features at an affordable price. It’s a great entry-level option for fitness tracking, notifications, and calls—especially if you’re in Nairobi looking for value without breaking the bank.
Key Features and Specs
- Display: Ultra-large 1.97-inch square AMOLED screen (390 x 450 resolution, ~302 PPI), 60Hz refresh rate, up to 600 nits brightness, always-on support. It’s bright outdoors, colorful, and sharp—reviews praise it as one of the best in its class for visibility and aesthetics.
- Design & Build: Aluminum alloy middle frame with rotating crown for navigation, quick-release straps (TPU silicone in most colors). Dimensions: 47.5 x 41.1 x 10.5 mm, weighs ~31.5g (light and comfortable, though the square case looks big on smaller wrists). Available in colors like Obsidian Black, Silver Gray, and strap variants (e.g., white/gray/beige).
- Battery Life: 470mAh battery—up to 20 days in typical use (notifications, heart rate monitoring), or up to 30 days in long battery mode. Real-world users often report 15–25 days depending on GPS/always-on usage—insanely long compared to many competitors.
- Health & Fitness Tracking: Continuous heart rate, blood oxygen (SpO₂), sleep analysis (including stages), stress monitoring, female health tracking. Over 150+ sports modes, built-in multi-system GNSS (GPS + Galileo/Glonass/BeiDou/QZSS) for independent outdoor tracking (no phone needed for runs/cycles).
- Smart Features: Bluetooth calling with built-in speaker/mic (clear calls), notifications, music control, weather, alarms, find my phone. Runs on Xiaomi HyperOS (smooth but some software quirks like occasional bugs or limited app ecosystem noted in reviews). Pairs with Mi Fitness app (Android/iOS).
- Durability: 5ATM water resistance (up to 50m)—safe for swimming, showers, rain (not diving/high-pressure water).
- Other: Bluetooth 5.3, sensors (accelerometer, gyroscope, compass), emergency SOS.
Reviews and Reception
It scores well (often 4–4.5 stars) as a “beautiful budget beast”—praised for the premium-looking AMOLED, marathon battery, accurate basics (heart rate/GPS), and value. TechAdvisor called it “big, budget & beautiful,” NotebookCheck noted great display/battery but some software flaws (e.g., UI glitches, less polished than premium watches). Reddit users love the longevity for daily wear. Drawbacks: No advanced features like NFC payments (in most regions), basic app ecosystem, heart rate less accurate during intense workouts, and it feels more “smartband-plus” than full smartwatch (no third-party apps).
