Selecting the best Garmin is no mean feat, considering that the 2026 line-up is simply amazing. However, after numerous tests and experiments, it seems that I have been using the Garmin Enduro 3 much more frequently than the Fenix 8. Although the Fenix 8 is undoubtedly the “glamour” watch, the Enduro 3 appears to be the authentic instrument for professional athletes.
The following are reasons why the Garmin Enduro 3 beats the Fenix 8 as my preferred device.
The Battery King Has Arrived
There is, of course, the matter of the battery life. Though the Fenix 8 Solar 51mm certainly isn’t bad in its own right, the Enduro 3 blows it out of the water. With its improved solar panel, I am seeing battery figures that seem almost impossible. In GPS mode, you could expect to hit 320 hours of battery life with plenty of sunshine.
If there is one thing that I hate doing when it comes to my smartwatch, it’s charging it. With the Enduro 3, I can literally forget about needing to plug it into the USB-C port for weeks on end, maybe even over a month. As DC Rainmaker pointed out in his extensive analysis of the Enduro 3, it is the “better Fenix 8” and the most efficient power-per-dollar watch from Garmin ever.
Weight and Wrist Comfort
Both watches have a case diameter of 51mm; however, in terms of comfort, the Enduro 3 is noticeably lighter than the Fenix 8. It has a weight of just 63g without the band, whereas the Fenix 8 weighs 72g and increases according to the materials used.
The difference may not seem significant at first glance, but when you think about how it would feel after running for 50 kilometers or hiking through rough terrain, those 9 grams will start to make a difference. In addition, I found the UltraFit nylon strap that comes as a default option with the Enduro 3 far more comfortable than the usual silicone straps that come with the Fenix models.
The MIP Display Advantage
Yes, we all know that AMOLED is the “future,” and the Fenix 8 display looks amazing. However, for me, the Memory-in-Pixel (MIP) display of the Enduro 3 beats the Fenix 8 screen in terms of practical use for training. The MIP display on the Enduro 3 is perfect under bright, direct sunlight, and I do not have to wake up the display or crank up the brightness level.
Tom’s Guide mentioned this correctly, and that is why I would say that the AMOLED display works best when you are using your watch indoors like a “smartwatch,” but outside, the MIP display of the Enduro 3 is still the champion of clarity.
Cutting Costs and Removing Unnecessary Features
There are three features in the Fenix 8 that I will not use: a microphone, a speaker, and waterproof buttons. They are really nice additions, but there is no need to pay extra for hardware features that aren’t necessary for me to use.
And guess what? It is less expensive, too. The Enduro 3 was released for $899 compared to the 51mm Fenix 8 Solar for $1,199. That means you will spend an additional $300 for a watch with a lower battery life and features that won’t improve your performance.
Expert Opinions: What the Pros Say
This opinion is echoed by other specialists who share my views regarding the Enduro 3 as the better option when it comes to performance:
-
DC Rainmaker: His reputation is based on his famous statement saying that the Enduro 3 is the “Cheaper/Better Fenix 8” since the device retains all necessary software features (the latest interface and mapping capabilities) and exploits its hardware to the fullest extent possible to achieve greater endurance.
-
The Quantified Scientist: The reviewer characterizes the device as a “specialist designed for one mission: unlimited endurance,” adding that if you lead an adventurous life in places where electricity outlets do not exist, the Enduro is your only true companion.
-
DesFit: Frequently makes mention that the Enduro 3 is basically just an enhanced Fenix 7X Pro—the most advanced qualities from its predecessor combined with the new software from the Fenix 8, all while reducing its cost.
Final Thoughts
However, the Fenix 8 is a masterful engineering marvel; however, it is a “jack of all trades.” The Garmin Enduro 3 is a professional. It is lightweight, durable, more affordable, and has an enhanced battery compared to its rivals. If one sees their watch not as a fashionable accessory but as something functional, then the decision becomes quite obvious. I would always choose endurance over a microphone.
