Amazfit GTS 4 vs Samsung Galaxy Watch 3
The Verdict
Amazfit GTS 4 and Samsung Galaxy Watch 3 target different priorities. Amazfit excels in battery longevity, delivering up to 8 days versus Galaxy Watch 3's 1.5 to 2 days, making it ideal for users who prefer infrequent charging. Its 1.75-inch AMOLED display (390 x 450 resolution) is sharper and larger than the Galaxy Watch 3's 1.4-inch Super AMOLED (360 x 360), while weighing just 27 grams versus 48-53 grams. Samsung Galaxy Watch 3 justifies its $399 price with superior health monitoring including ECG capability and premium build materials like stainless steel and titanium, plus NFC for contactless payments and cellular connectivity for standalone operation. The Tizen OS ecosystem offers deeper Samsung integration and more apps. Battery life difference is dramatic: GTS 4 users charge weekly while Galaxy Watch 3 owners charge every 1.5 days. For fitness tracking and everyday wear comfort, Amazfit GTS 4 wins decisively. If you need advanced health sensors, premium materials, and don't mind daily charging, Galaxy Watch 3 delivers. Most buyers seeking practical value and hassle-free battery management should choose Amazfit GTS 4.
