I’ve run this route a number of times before using Strava and the GPS in my Huawei P9, and it’s typically recorded at around 2.85 to 2.9km. However, distance even with the connected GPS seemed to sell me short. That was impressive considering accelerometer-based tracking can be significantly off the mark. The first GPS-connected route was recorded at 2.64km, while the run sans smartphone came up at 2.65km. The real surprise was the margin of error between the results. I took the Charge 2 for a number of test runs, including running the same route back-to-back – once with connected GPS and once without. GPS information will automatically get pulled in. Just start running and it will track in the background, or use the Charge 2 to manually start the run if you want running metrics on the display. You don’t need to trigger the run from the app, either. There’s also no built-in GPS, but if you do go for a run with your smartphone paired, the Charge 2 can use connected GPS for tracking distance and routes.

Without the waterproofing seen on the new Flex 2, swimming is a no-go – which is a shame. Otherwise, you can trigger these from the button on the side. The Charge 2 can begin automatically tracking selected sports and exercises such as hiking, cycling and, of course, running. Slightly disappointingly, it isn’t a smart alarm that can wake you up at a more optimal time. App, battery life & verdict ReviewĪs you’d expect, the Charge 2 has the usual all-day activity and sleep tracking with silent alarm.
