Amazfit GTS 4 Mini vs Garmin Venu Sq 2
The Verdict
Both watches deliver solid fitness tracking at different price points. Amazfit GTS 4 Mini excels with exceptional 15-day battery life, lighter 31.2g build, and vibrant 336x384 AMOLED display, all at a budget-friendly $99. Garmin Venu Sq 2 costs $250 but adds NFC payments, WiFi connectivity, and superior GPS endurance at 26 hours, plus Garmin's industry-leading workout ecosystem. Health features are comparable: both track heart rate, SpO2, and sleep, though neither includes ECG or skin temperature monitoring. Display sizes are similar (42mm vs 40mm), yet Amazfit's higher resolution offers crisper visuals. Battery longevity heavily favors Amazfit for casual users seeking weekend-free charging. Choose Amazfit GTS 4 Mini if budget matters and daily tracking suffices; select Venu Sq 2 for serious athletes needing advanced Garmin training metrics, contactless payments, and extended GPS adventures.
