Amazfit GTR 4 vs Fitbit Versa 4
The Verdict
Amazfit GTR 4 excels in battery longevity with up to 14 days of normal use versus Fitbit Versa 4's 6 days, making it ideal for users prioritizing extended wear between charges. Versa 4 compensates with superior health tracking features: ECG capability and skin temperature monitoring that GTR 4 lacks, plus a larger 1.58-inch AMOLED display versus GTR 4's 1.43 inches. Both offer GPS, NFC, SpO2, and heart rate monitoring. GTR 4's lighter 34g design and Zepp OS provide snappier performance, while Versa 4's transition to Wear OS promises better app ecosystem long-term. Price-wise, Versa 4 undercuts at $179 versus $199. Choose GTR 4 if battery life dominates your priorities; select Versa 4 for comprehensive health data and ecosystem potential despite shorter battery endurance.
