Battery life is a standout across reviews, with multi-day real-world endurance and especially strong results on larger or solar variants.

Product 2: Garmin Forerunner 570

Calls work, but audio quality is a compromise: reviewers noted quiet speaker output and less-than-ideal voice clarity.

4.6

Durability impressions are positive. Reviewers mention scratch resistance, pristine condition after use, and very little visible wear over time.

ECG functionality
Product 1: Garmin Fenix 8
3.6

ECG hardware is present, but availability remains region-limited rather than universally accessible.

Product 2: Garmin Forerunner 570

Product 2: Garmin Forerunner 570
4.3

Health stats are generally described as good, with one data-driven review calling overall stat accuracy solid and another saying heart-rate and sleep-stage tracking are pretty good.

heart rate accuracy
Product 1: Garmin Fenix 8
4.3

Heart-rate accuracy is generally strong, but fast intervals and some sport-specific edge cases still trip it up.

Product 2: Garmin Forerunner 570
4.6

Heart-rate tracking is a major strength. Multiple reviewers say it stays close to chest straps, performs well in intervals, and is one of Garmin’s better recent sensors.

LTE connectivity
Product 1: Garmin Fenix 8
