Amazfit GTS 4 vs Samsung Galaxy Watch 4
The Verdict
Both smartwatches deliver premium experiences with distinct strengths. Amazfit GTS 4 excels in battery life, lasting up to 8 days versus Galaxy Watch 4's typical 20 hours, making it ideal for users prioritizing longevity. Samsung's offering compensates with superior health tracking via ECG capability (missing on Amazfit), NFC for contactless payments, and optional LTE connectivity. Display quality favors Samsung's Super AMOLED with higher resolution options (450x450 on 44mm), while Amazfit counters with excellent AMOLED performance in a lighter, more compact 42mm form factor. Galaxy Watch 4 runs Wear OS 3.0 with broader app compatibility and Google integration, whereas Zepp OS 2.0 offers simplicity but limited ecosystem. At $199 versus $249, Amazfit GTS 4 represents exceptional value for fitness-focused users who value battery endurance. However, Samsung Galaxy Watch 4 is the better all-rounder for those wanting comprehensive health monitoring, mobile payments, and deeper smartphone integration. Choose Amazfit for battery longevity; pick Samsung for feature completeness.
