Fitbit Charge 6 vs Huawei Watch GT 4 (46mm)
The Verdict
Fitbit Charge 6 excels as a Google ecosystem smartwatch with fitness-focused features, offering ECG capability, NFC payments, and solid AMOLED display in a lighter 37g aluminum package. Its 7-day battery life is respectable, though not exceptional. Huawei Watch GT 4's 46mm model dominates with a larger 1.43-inch AMOLED screen featuring superior 466x466 resolution, plus skin temperature monitoring and nearly double the battery endurance at 14 days. The 48g stainless steel build feels more premium, with Bluetooth 5.2 and excellent health tracking minus ECG. GT 4 costs $90 more but delivers significantly better longevity between charges and a more immersive display experience. Choose Fitbit if you're invested in Google services and value portability; pick Huawei GT 4 if battery life and screen real estate matter most and you can work within HarmonyOS's app ecosystem.
