So this is not going to be a marathon option – or even half-marathon option for most. The longest run we did with the Charge 4 was just over 1:40 and after that the battery was down to around 20 per cent. It offers seven days in normal mode and Fitbit claims a life of five hours in GPS mode. The downside of this is that the battery life in GPS is poor.

The GPS (built in for the first time on a Fitbit tracker) performed impressively well compared with a Garmin Fenix 5 and an Apple Watch, so if accurate pace/distance stats are your only/main concern and you’re not interested in other factors, the Charge 4 will meet your needs. That said, the touchscreen controls work well without you having to paw at the device – a bugbear of ours – and there is one button on the side that can also be used to wake the screen, as well as pause/resume sessions. The pixelation means it’s tricky to see on the run, and the Apple Watch-style ‘sleep screen’ function – where you raise your wrist to turn the screen on – doesn’t work well consistently. The screen is too slim and visibility is poor.
