Garmin Enduro 4 arrives with huge battery life, but the Fenix 9 may still be the better buy
Garmin has expanded its premium smartwatch lineup with the new Garmin Enduro 4, a rugged multisport GPS watch built for athletes who want maximum battery life, reliable navigation, and durable outdoor performance. As expected from the Enduro series, endurance is the main attraction. This is a watch designed for ultra-distance runners, hikers, cyclists, and outdoor adventurers who do not want to worry about charging during long training blocks or multi-day trips.
The Enduro 4 sits close to Garmin’s Fenix family in terms of core features. Like the Fenix 9, it offers advanced fitness tracking, offline maps, standalone navigation, and a wide range of sports modes. However, Garmin clearly positions the Enduro line around one major advantage: extended battery life. For serious endurance athletes, that can be a major selling point. For more casual users, it may simply mean charging the watch far less often.
Compared with the Garmin Enduro 3, the Enduro 4 brings several refinements. The case design has been updated, and Garmin has also revised the strap system. Internal storage has doubled to 64 GB, giving users more room for maps and data. That sounds impressive, although the previous 32 GB capacity was already enough for most owners.
Performance has also improved. The Enduro 4 includes 50% more RAM and uses the newer processor platform also found in the Garmin Fenix 9 series. In everyday use, this should make the watch feel a bit faster and smoother, especially when working with maps. Zooming and moving around maps is more fluid, and Garmin has introduced a slightly angled map view that can make navigation feel more natural.
Still, the performance jump may not be dramatic for everyone. The biggest gains are likely to appear in demanding situations, such as loading very long and complex routes directly on the watch. For normal workouts, navigation, and daily smartwatch use, the difference between the Enduro 3 and Enduro 4 may only be a matter of seconds.
That raises an important question: should Enduro 3 owners upgrade to the Garmin Enduro 4? For many people, the answer may be no. The new model is clearly better, but not necessarily better enough to make an upgrade essential. If the Enduro 3 already meets your needs, especially in terms of battery life and mapping, the Enduro 4 may feel more like a refinement than a must-have replacement.
For new buyers, the decision becomes more interesting. The Garmin Enduro 4 offers excellent endurance, a memory-in-pixel display, strong outdoor features, and improved hardware. But Garmin’s own Fenix 9 may be a more appealing all-around smartwatch for many users.
One key difference is size. The Enduro 4 is available only in a large 51 mm case, which may not suit every wrist. The Fenix 9, on the other hand, comes in multiple case sizes, making it easier to find a comfortable fit. The Fenix 9 also includes extra hardware features, such as a microphone and dedicated diving functions, giving it broader appeal beyond endurance sports.
The Enduro 4 does have one important advantage for fans of traditional outdoor sports watches: it keeps the memory-in-pixel display instead of switching to AMOLED. While AMOLED screens are brighter, more colorful, and increasingly common in premium smartwatches, many outdoor athletes still prefer memory-in-pixel displays for their excellent visibility in sunlight and efficient power use. For users who prioritize battery life and outdoor readability over vivid colors, this remains a strong reason to consider the Enduro 4.
Ultimately, the Garmin Enduro 4 is a highly capable multisport GPS watch with outstanding battery life, improved performance, more storage, and refined mapping. It is best suited for endurance athletes and outdoor users who need maximum runtime and dependable navigation.
However, it is not an obvious upgrade for Enduro 3 owners, and it faces strong competition from the Garmin Fenix 9. If you want the longest battery life and prefer a memory-in-pixel display, the Enduro 4 is a compelling option. If you want more size choices, extra smartwatch features, and a more versatile premium package, the Fenix 9 may be the smarter choice.
