Expert opinion
The Active Max scored 81% on tfk’s standard 10-mile GPS accuracy test, a second-tier result behind the best current dual-frequency chipsets such as the Suunto Vertical and Coros Pace 3 at 92%, but ahead of typical single-frequency watches at this price. Its Airoha AG3352B chipset performed well in a road tunnel and in sections prone to multipath error near buildings, weaker on some easy-reception sections than expected. Heart rate accuracy was inconsistent: some workouts matched a reference to within 1%, others showed workout-level errors up to 10% from underreporting during harder efforts. Amazfit claims up to 64 hours of continuous GPS recording; real-world estimation during testing suggested closer to 40 hours at minimum brightness with the always-on display disabled, though this remains competitive at the price. The watch has no ANT+ support, cannot control a smart trainer, and does not sync inbound Strava routes, though it does sync structured TrainingPeaks workouts and supports Stryd running power.

Battery life
Amazfit claims up to 25 days of typical smartwatch use and up to 64 hours of continuous GPS recording, figures enabled by the single-frequency chipset, a lightweight OS and a large 658mAh cell. In mixed real-world use including regular GPS workouts, a week between charges was comfortably achievable. Estimated continuous GPS battery life from testing was closer to 40 hours at minimum brightness with the always-on display disabled, still competitive against rivals at this price. Charging is not fast: roughly 2 hours for a full charge, with around 50% reached in an hour.
