Amazfit GTS 4 vs Samsung Galaxy Watch 5
The Verdict
Samsung Galaxy Watch 5 delivers superior health tracking with ECG and skin temperature monitoring absent on the GTS 4, plus faster wireless charging and Wear OS 3.5's broader app ecosystem. Battery life claims differ significantly,Samsung advertises 40 hours versus Amazfit's 8 days, though real-world usage typically sees the Watch 5 lasting 24 hours. Amazfit GTS 4 compensates with exceptional actual longevity, lighter weight (27g), and lower price point at $199 versus $279. Display quality favors Samsung's Super AMOLED with sharper 396x396 resolution on the 40mm model. For health-conscious users prioritizing comprehensive metrics and app variety, Galaxy Watch 5 justifies the premium. Budget-conscious buyers seeking reliable fitness tracking and extended battery life should choose the GTS 4.
