Amazfit GTR 4 vs Apple Watch Series 9
Side-by-side specifications, scores and verdict.
Quick Verdict
Amazfit GTR 4 dominates battery endurance with an impressive 14-day normal mode versus Apple Watch Series 9's 18-hour runtime, making it ideal for users prioritizing longevity between charges. Apple's offering delivers superior health monitoring with ECG and skin temperature sensors absent on the Amazfit, plus watchOS 10's ecosystem integration and cellular connectivity. Display quality favors Apple's 45mm Always-On Retina LTPO OLED (484 x 396), though the Amazfit's 1.43-inch AMOLED (466 x 466) remains vibrant. Performance-wise, both feature 1GB RAM but Apple's S9 SiP chip provides faster app execution. At $199 versus $399, the Amazfit GTR 4 represents exceptional value for fitness tracking and daily wear without frequent charging, while the Apple Watch Series 9 justifies premium pricing through comprehensive health features and seamless iPhone integration. Choose Amazfit for marathon battery life; Apple for complete health insights and ecosystem connectivity.
