Battery & Elevation Test: Garmin Edge 830 vs. Stages Dash vs. Wahoo Elemnt Roam

Three high-end cycling GPS computers. One 14,000-foot elevation test. Which computer came out on top?

If you are looking to do a big ride where elevation is important—Everesting, anyone?—what is your best bet for a cycling GPS computer? As part of the VeloNews Project 14er, I tested three computers for battery life and elevation accuracy.

The three computers in this test and their claimed battery lives were:

I tested them by climbing 14,000 feet with my colleague Betsy Welch, starting from a known elevation in Idaho Springs, Colorado, and riding to the top of Mount Evans—twice. While each computer has its own pros and cons, we focused just on two things in this video: battery life and elevation accuracy.

Active Pass software, powered by Today’s Plan, allows you to overlay data from multiple sources. I typically use this to compare power data from different meters or smart trainers, but it also works for elevation comparisons, too. Since the climb was 6,500 feet, we had to add an extra 1,000 feet on the second lap by doubling back midway up. Photo: Ben Delaney

To make the battery test as apples-to-apples as possible, I standardized the computers by following a route and using power on each. For the Edge 830 and the Dash L50, I set the brightness level to auto. Battery life could have been increased on both—especially the Dash, which runs very bright—by manually lowering the brightness. The Elemnt Roam doesn’t offer any brightness adjustment, it just does it on its own.

To judge elevation, I used known U.S.G.S. elevation data from the bottom and top. I consulted Strava but did not rely on it entirely. Strava is a great resource for camaraderie and ride inspiration, and the elevation data on the site is helpful but not always 100% precise. For instance, Strava Segments are based solely on the elevation recording of the single computer from the individual who created the Segment. Strava Routes, on the other hand, use a compilation of elevation data from Strava’s database.

Watch the video above to see how each computer fared.

The Stages Dash at center had the highest battery burn rate, but also the brightest screen, as you can see.
