The Garmin Fenix 9 and Enduro 4 could be launching soon, code spotted in Garmin Connect app suggests

The Garmin Enduro 4 has appeared as a reference in the back-end code of the Garmin Connect app

The code doesn't specify a release date, but it's a new addition in the app's latest update

It points to a launch for the Enduro 4 and Fenix 9, as previous versions of both devices have launched together

I've been devouring every crumb of news we can get about the Garmin Fenix 9 range, and when it will launch. After all, the Fenix 8 quickly made our list of the best Garmin watches after it launched, and is Garmin's preeminent premium watch.

The Enduro series, meanwhile, is effectively a powerful, battery life-focused version of the Fenix watches, and the Enduro 3 launched alongside the Garmin Fenix 8 in 2024. In our Garmin Enduro 3 review we said "the Enduro line puts battery first, all while offering most of the features from the Fenix series", with our reviewer getting almost a month's worth of battery from a single charge.

So it's exciting to hear our first whispers about the Garmin Enduro 4, as it suggests the full Fenix 9 range could be coming soon.

How the Garmin Enduro 4 leaked

The latest information comes courtesy of Gadgets & Wearables, which did an APK teardown examining the code of version 5.26 of the Android Garmin Connect app, and spotted 'Enduro 4' in a device registry.

This was reportedly not in version 5.25, suggesting it's a recent addition — and that a launch could be imminent.

It only adds weight to recent rumors that the Fenix 9 is coming soon. Garmin CEO Cliff Pemble reassured investors earlier this year that he expected "stronger performance in the back half of the year due to the timing of product launches," and that it would be "a very active year for outdoor".

Garmin's outdoor line of watches includes the Garmin Fenix series, alongside other high-profile entries such as the Garmin Instinct series. Given that the Garmin Instinct 3 arrived last year, and that the Fenix 8 is now a few years old, it's not hard to connect the dots. More soon.
