How to decide
Battery Life Comparison
When it comes to battery life, the Garmin Enduro 3 absolutely crushes the competition with an astonishing 36 days in smartwatch mode and up to 120 hours in GPS mode. The Forerunner 965 offers a respectable 23 days in smartwatch mode, but pales in comparison to the endurance of the Enduro 3. Meanwhile, the fēnix 8 provides 16 days, which is still impressive but not enough for serious ultra-runners. The Venu 3, with only 14 days, is great for casual wear but may not suffice for long-distance training. Battery life is a crucial factor for runners who spend extended hours outdoors, and the Enduro 3's capabilities ensure you won't be left in the lurch.
Sensor Package Insights
The sensor package is where the Garmin Enduro 3 shines, featuring the Elevate Gen 5 optical heart rate sensor and Pulse Ox blood oxygen monitor, which are critical for advanced health metrics. The Forerunner 965 also includes an impressive array of sensors, but lacks the ECG capability found in the fēnix 8. The Elevate Gen 5 sensor in the Venu 3 supports ECG, but its overall performance is less robust compared to the Enduro 3. For serious runners, having the best sensors is crucial for tracking performance and making informed training decisions. The Enduro 3’s superior sensor suite ensures you have all the data you need at your fingertips.
Display Brightness and Quality
The Garmin fēnix 8 features a stunning AMOLED display with a peak brightness of 1000 nits, making it ideal for use in direct sunlight. In contrast, the Enduro 3 uses a MIP display that excels in daylight but doesn’t offer the vibrant colors of AMOLED when indoors. The Forerunner 965 also sports an AMOLED display but has a lower resolution compared to the fēnix 8. Display quality is essential for quick readability during runs, and while the fēnix 8 offers the best visual experience, the Enduro 3’s visibility in all conditions makes it a practical choice for outdoor activities.
