Amazfit GTS 4 vs Garmin Instinct 2
The Verdict
Amazfit GTS 4 and Garmin Instinct 2 target different users. The Amazfit GTS 4 excels with its vibrant AMOLED display (390 x 450 resolution), weighing just 27 grams, and costs $150 less. Battery life reaches 8 days under typical use with built-in WiFi connectivity for seamless updates and features. Health tracking includes SpO2 and continuous heart rate monitoring, plus sleep tracking. However, the Garmin Instinct 2 ($349) dominates durability and battery endurance, surviving MIL-STD-810 standards and 10ATM water resistance compared to Amazfit's 5ATM. Garmin's 24-day battery life (or 30 days with solar) vastly outlasts Amazfit, crucial for outdoors enthusiasts. The Instinct 2's monochrome MIP display sacrifices visual appeal for power efficiency and outdoor readability. Garmin offers pure ruggedness and navigation focus; Amazfit prioritizes everyday style and display quality. Choose Amazfit GTS 4 for fashion-conscious fitness tracking and daily wear, or pick Garmin Instinct 2 if extreme durability and multi-week battery matter more than screen beauty.
