In a more extreme marathon test, the Charge 5 reported 38km rather than the full 42km, and it also didn’t deliver mapping data in the app post-run – though the heart rate monitoring largely matched up with a chest strap monitor, so while there are still niggles, there are positives here too. Running metrics such as average pace then clocked us going much faster or slower than we were. On shorter runs, the GPS came up short against a Garmin running watch. But it was a bit of a mixed bag in our outdoor running tests, in terms of accuracy. It’s when Fitbit looks to go beyond those tracking staples that it still comes a little unstuck.įitbit added built-in GPS to the Charge 4 and the feature remains on the latest edition, letting you track any of the outdoor activities covered in the 20 exercise modes available on the Charge 5. If you care about counting steps, monitoring your heart rate continuously or receiving useful and reliable sleep tracking data and insights, that’s what you’ll get from the Charge 5. Fitness tracking is one of Fitbit’s strengths.
