Amazfit GTS 4 Mini vs Withings ScanWatch
The Verdict
Amazfit GTS 4 Mini and Withings ScanWatch target different smartwatch philosophies. The Amazfit delivers a full 1.65-inch AMOLED display with 336x384 resolution, GPS navigation, and Zepp OS's extensive app ecosystem, all while weighing just 31.2g. Battery lasts around 15 days with typical mixed usage. The Withings ScanWatch takes a hybrid approach, pairing a traditional analog dial with a small PMOLED secondary display, achieving an impressive 30-day battery life. It includes ECG capability for medical-grade heart monitoring, while the Amazfit lacks this feature. The ScanWatch is significantly heavier at 58g and costs three times more, but offers premium stainless steel construction with sapphire crystal and WiFi connectivity for standalone syncing. The Amazfit excels for fitness enthusiasts wanting comprehensive training data and app variety on a vibrant screen. The Withings suits those prioritizing all-day battery life, medical-grade health insights, and a sophisticated analog-watch aesthetic. At $99, the Amazfit provides exceptional value for active users. The ScanWatch justifies its premium pricing through specialized health features and longevity between charges, though it sacrifices smartwatch functionality for a more traditional wearable experience. Choose Amazfit for versatility and fitness tracking, or Withings if health monitoring precision and minimalist design matter most.
