Amazfit GTR 4 vs Samsung Galaxy Watch 7
Side-by-side specifications, scores and verdict.
Quick Verdict
Amazfit GTR 4 excels in battery longevity with an impressive 14-day runtime in normal mode, making it ideal for users prioritizing extended wear between charges. Samsung Galaxy Watch 7 counters with superior health tracking—featuring ECG and skin temperature monitoring absent on the Amazfit—plus a brighter AMOLED display (2000 nits vs. unspecified), more robust processor (5-core Exynos W1000 with 2GB RAM), and Wear OS 5's broader app ecosystem. The Galaxy Watch 7's 30-hour battery still demands daily charging despite premium positioning. Build quality favors Samsung with Armor Aluminum and Sapphire Crystal protection. For fitness enthusiasts and health-conscious users willing to charge nightly, the Galaxy Watch 7's comprehensive health suite and software capabilities justify the $100 premium. Budget-conscious buyers prioritizing endurance should choose the Amazfit GTR 4.
