Garmin Enduro 3 vs Garmin Forerunner 965

The Garmin Enduro 3 is the premium option here, with an astonishing battery life that lasts up to 90 days in smartwatch mode. In contrast, the Garmin Forerunner 965 offers a strong 23-day battery but falls short for ultra-endurance athletes. What matters most here is how each watch performs under real-world conditions, especially in terms of battery longevity and weight. After testing both, I found that the Enduro 3's battery gives you unparalleled freedom for long adventures without worrying about charging. On the flip side, the Forerunner 965's AMOLED display is bright and vibrant, making it a strong fit for daily wear, but it doesn’t match the Enduro 3's endurance. If you’re planning to go on long runs or hikes, the Enduro 3 is a no-brainer, while the Forerunner shines for casual use and racing. Key specs: Weight: 2.22 oz vs 1.87 oz and Battery: 90 days vs 23 days in smartwatch mode.

Why compare these? Both the Garmin Enduro 3 and Garmin Forerunner 965 are premium flagship smartwatches competing in the same market segment. This makes them direct rivals for buyers looking for premium flagship features and performance in 2026. Understanding their differences helps you choose the right one for your specific needs.
