Across the broad feature landscape, these two watches are strikingly well-matched. Both deliver HRV tracking, VO2 max estimation, resting heart rate monitoring, readiness scoring, irregular heart rate warnings, call handling, notifications, vibrating alerts, a stopwatch, and a camera remote — a feature set that covers health monitoring, communication, and everyday smartwatch utility comprehensively on either device.
Two standout differentiators pull in opposite directions. The Huawei Watch Fit 4 Pro includes ECG technology, which the Bip 6 lacks — a clinically significant addition that allows users to take on-demand electrocardiogram readings directly from the wrist, useful for detecting atrial fibrillation and providing data that can be shared with a physician. It also offers substantially more internal storage at 4 GB versus just 0.5 GB on the Bip 6, which matters for users who want to store music or data locally on the device. The Amazfit Bip 6 counters with voice commands, a convenience feature absent on the Huawei that allows hands-free interaction — practical during workouts or when the phone is out of reach.
Weighed against each other, the Huawei's advantages carry more substance. ECG is a meaningful health monitoring capability that goes beyond what most fitness trackers offer, and the 8x storage advantage opens up use cases the Bip 6 simply cannot support. Voice commands are useful but represent a narrower day-to-day benefit by comparison. The Huawei Watch Fit 4 Pro holds the stronger hand in this category, particularly for health-conscious users who want deeper cardiac insight.
