What are the main differences in GPS accuracy between Amazfit and Garmin

I have gathered information from recent reviews, user feedback, and technical analyses regarding the GPS accuracy of Amazfit smartwatches versus Garmin models. Here is an outline of the main findings and differences:

***

GPS Accuracy Technology and Hardware

Amazfit watches, particularly newer models like the Amazfit Balance and the Active series, are equipped with advanced GPS technology, including dual-frequency GPS chips operating on L1 and L5 frequencies. This multi-band GNSS support helps improve satellite signal reception and accuracy, especially in challenging environments such as urban areas with high-rise buildings or dense tree cover. The cutting-edge circularly-polarized GPS antennas in some Amazfit models also contribute to better signal acquisition and accuracy across five satellite systems.

Garmin has long built its reputation on superior GPS accuracy, using highly precise GNSS chips supporting multiple satellite constellations including GPS, GLONASS, and Galileo. Garmin devices frequently use advanced positioning algorithms and satellite system selection to maximize accuracy and reliability in navigation and tracking.

While Amazfit has made significant strides by incorporating multi-band GNSS and dual-frequency GPS, Garmin's GPS is considered to be one of the most precise in the industry, especially in complex or high-demand scenarios.

Real-World GPS Performance and Accuracy

User reports and detailed reviews indicate that Amazfit GPS accuracy is generally solid, especially for casual running and outdoor activities. Typical GPS satellite fix times are between 5 to 10 seconds. Amazfit watches perform well on straight segments and moderate-speed routes on cycling and running, but some high-speed corners and curves show occasional overshooting, where GPS trails veer slightly outside the actual path taken. This does not generally affect total distance measurements significantly, but might reduce path precision in technical trail running or cycling.

Garmin watches offer highly reliable GPS tracks that closely follow the actual path with excellent precision through curves and complex routes. Garmin's algorithms produce crisp and accurate location traces with minimal deviation, giving users confidence in distance and pace data critical for training and navigation.

Several GPS comparison tests reveal that while Amazfit's GPS is accurate enough for most users, Garmin consistently delivers a sharper and more trustworthy GPS route accuracy. Garmin's superior GPS accuracy translates into more precise elevation gain data, route adherence, and pace tracking, important for athletes and outdoor adventurers demanding high fidelity.

Software Ecosystem and GPS Features

Garmin provides an integrated ecosystem that enhances GPS capabilities beyond raw location accuracy. Its watches support multiple satellite systems simultaneously, intelligent GPS modes (e.g., SatIQ automatic balancing between accuracy and battery life), routable maps, turn-by-turn navigation, pace strategy tools, breadcrumb trails, and extensive sport mode tracking.

Amazfit focuses on user-friendly GPS features with dual-frequency GPS accuracy enhancements and good baseline sports tracking. Some models support offline maps and basic navigation but lack the depth of mapping and navigation tools Garmin offers. Amazfit's GPS modes include power-saving single-band and high-accuracy dual-band modes that balance battery life with tracking precision.

Training Data and Metric Accuracy Impact

From user community feedback and expert reviews, it appears that while Garmin leads in GPS accuracy, the differences in metrics derived from GPS data—such as training load, recovery, heart rate variability, and calorie expenditure—between Amazfit and Garmin are often minor or statistically modest.

Garmin watches tend to have more precise calorie estimation and stress monitoring, while Amazfit devices sometimes overestimate calories burned but provide largely comparable training load and recovery insights. GPS accuracy differences have limited impact on these derived health and training metrics for casual to moderate athletes.

Battery Life vs. GPS Accuracy Tradeoff

Both brands implement strategies to balance GPS accuracy with battery life:

- Amazfit uses adaptive modes that switch between dual-frequency and single-frequency GPS to optimize battery usage. Users can get substantial GPS active times ranging from about 26 hours in highest accuracy modes to over 50 hours in power-saving GPS modes.

- Garmin devices, depending on the model, also offer multiple GPS accuracy settings and satellite system combinations to extend battery life while maintaining solid tracking. Typically Garmin watches provide robust battery performance even with high-accuracy GPS modes enabled, supporting long-distance events and multi-day adventures.

Summary of Key Differences

- Amazfit offers very good GPS accuracy for casual users with dual-frequency GPS, multi-satellite support, and competitive battery life, but occasionally shows minor deviations on high-speed corners or complex paths.

- Garmin maintains the edge in GPS precision, particularly in challenging environments or for users requiring highly detailed route tracking and advanced navigation features.

- Garmin's software ecosystem enriches the GPS experience with routable maps, advanced pacing, and navigation beyond raw tracking.

- Metric accuracy from training data is broadly similar, with Garmin generally providing slightly better stress and calorie metrics.

- Battery life strategies differ, with both brands offering modes to extend GPS usage balanced against accuracy.

This detailed comparison shows Garmin still leads as the industry standard for GPS accuracy and advanced GPS features, whereas Amazfit offers strong value and capable GPS for everyday users. The choice depends on a user's needs—priority on absolute GPS precision and features versus affordability and adequate GPS for casual or mid-level fitness tracking.
