Amazfit GTR 4 vs Samsung Galaxy Watch Ultra
Side-by-side specifications, scores and verdict.
Quick Verdict
Amazfit GTR 4 delivers exceptional value with its 14-day battery life, vibrant 1.43-inch AMOLED display, and essential health tracking (heart rate, SpO2, sleep) at $199. Samsung Galaxy Watch Ultra commands premium pricing at $650 with titanium construction, advanced health features (ECG, skin temperature), superior 3000-nit Super AMOLED display, and LTE connectivity for standalone calls/texts. Performance-wise, the Exynos W1000 chip with 2GB RAM significantly outpaces GTR 4's Huangshan processor, enabling smoother app performance and faster load times. Battery endurance heavily favors GTR 4 in standard mode (14 vs 60 hours in Power Saving mode). Health tracking is comprehensive on both, but Ultra's ECG and skin temperature monitoring provide deeper insights. For fitness enthusiasts seeking affordability and longevity between charges, GTR 4 excels. For professionals requiring cellular independence, premium durability (Titanium Grade 4), and advanced biometric data, Galaxy Watch Ultra justifies its premium investment. Choose GTR 4 for value; choose Ultra for capability.
