Comparing GPS, Heart Rate, and Cadence Smartwatches: Amazfit Balance 3 vs High-End Garmin

The Amazfit Balance 3 recorded GPS, heart rate, and cadence data nearly identical to a high-end Garmin during a 7.5K run, according to a side-by-side performance test by Gadgets & Wearables. While the devices showed minimal variance in raw biometric and spatial tracking, the Garmin provided significantly more detailed training analysis and recovery metrics.

The test, published June 26, 2026, focused on how the Amazfit Balance 3 compares to Garmin’s premium athletic tier in real-world conditions. The results indicate that the gap in hardware sensor accuracy between mid-range and high-end wearables has narrowed, even as the gap in software-driven athletic insights remains wide.

How did the raw metrics compare?

During the 7.5K distance, the Amazfit Balance 3 and the Garmin device produced closely aligned results across three primary data points: GPS distance, heart rate, and cadence. This parity suggests that the optical heart rate sensors and GNSS (Global Navigation Satellite System) chips in the Amazfit device perform at a level comparable to Garmin’s professional-grade hardware for standard running activities.

According to Gadgets & Wearables, the cadence—the number of steps a runner takes per minute—showed little to no meaningful difference between the two watches. This consistency is critical for runners who use cadence to optimize form and reduce injury risk.

The similarity in heart rate data indicates that the Amazfit Balance 3’s PPG (photoplethysmography) sensor effectively tracks cardiovascular effort during steady-state exercise, matching the readings of the more expensive Garmin alternative.

Why was there a gap in training analysis?

Despite the hardware parity, the two devices diverged sharply in how they interpreted the data. Gadgets & Wearables reported bigger gaps in training analysis, referring to the software algorithms that transform raw numbers into actionable athletic guidance.

High-end Garmin devices typically utilize a suite of proprietary metrics, including Training Load, Recovery Time, and Training Readiness. These tools analyze the relationship between heart rate variability (HRV), sleep quality, and exercise intensity to tell a user if they are overtraining or ready for a high-intensity session.

The Amazfit Balance 3 provides fitness tracking and health snapshots, but it lacks the deep longitudinal analysis found in Garmin’s ecosystem. Where the Garmin analyzes the physiological impact of the 7.5K run to suggest a specific recovery window, the Amazfit primarily records the event as a completed activity with basic summary statistics.

What does this mean for wearable consumers?

The findings highlight a shift in the wearable market where “accuracy” is no longer the primary differentiator for premium brands. For a casual runner or a fitness enthusiast, the Amazfit Balance 3 provides the necessary raw data to track progress without the high cost of a professional sports watch.

However, for competitive athletes, the value of a high-end Garmin lies in the interpretation of data rather than the collection of it. The ability to quantify “strain” and “recovery” allows athletes to adjust their training volume based on physiological markers, a feature that remains a competitive advantage for Garmin.

This distinction mirrors a broader trend in the industry where hardware commoditization is forcing premium manufacturers to pivot toward software services and AI-driven coaching to justify higher price points.

The Amazfit Balance 3 positions itself as a lifestyle and wellness tool that can handle athletic tasks, while the Garmin remains a dedicated training tool that happens to function as a watch.
