Amazfit GTS 4 vs Amazfit GTS 4 Mini
The Verdict
Both smartwatches share Zepp OS 2.0 and core health features, yet diverge meaningfully in design and endurance. GTS 4 delivers a larger 1.75-inch AMOLED display with 390x450 resolution, offering sharper visuals and more screen real estate, plus WiFi connectivity for enhanced features. Its 8-day battery satisfies typical users seeking daily-use convenience. GTS 4 Mini compensates with exceptional 15-day battery life, making it ideal for travelers and those prioritizing minimal charging. At 31.2g versus 27g, the Mini feels slightly bulkier despite its smaller display. Both feature 5ATM water resistance, GPS, and SpO2 monitoring. Performance difference remains negligible given identical processors. Choose GTS 4 if you value display quality and smart features; select GTS 4 Mini if extended battery life and budget ($99 versus $199) matter most. For most users, the Mini's half-price tag and fortnight endurance make it exceptional value.
