The Fitbit Charge 4, just announced, doesn’t change much visually from the previous model. It does, however, incorporate a GPS and SpO2 sensor to focus on active minutes rather than steps, and it’s much smarter.
Already seen through a few rumors, the Fitbit Charge 4 is now official. The excellent activity wristband doesn’t change its look but incorporates some exciting new features. In particular, it is the first tracker of the American brand to have an integrated GPS to track training sessions better outdoors. It must be admitted that in full confinement, it is not the best marketing asset, but there is no doubt that it will be useful to some people as soon as outings are allowed again.
Contactless payment and Spotify
Also, there are other new features such as Spotify management directly on the wrist (remember that despite compatibility with Google Fit and Apple Health, this is a proprietary operating system that animates the object, which limits the number of compatible applications), as well as contactless payment.
Autonomy is announced at 7 days, or 5 hours with the GPS continuously active.
Active minutes rather than steps
Counting the number of steps to motivate oneself to exercise is good, but for those who are exercising with a performance goal, this indicator is far from relevant. After all, walking or running around your block doesn’t require as much energy.
So, as is already the case with some applications, such as Google Fit, for example, the Fitbit Charge 4 carefully monitors all activities that increase the user’s heart rate, with the goal of the 150 minutes per week recommended by the World Health Organization. It also allows those who wish to lose weight to have a better vision of the fat elimination and cardio zones to modulate their exercises correctly.
Sleep and oxygen in the blood
In addition to GPS, the Fitbit Charge 4 gains the sleep tracking function found on the brand’s watches, which we rather appreciated during our test of the Versa 2. The application generates a “sleep score,” which is displayed directly on the screen of the bracelet connected to the alarm clock.
Finally, there is also a SpO2 sensor in the small case that estimates variations in the oxygen saturation rate in the blood. It makes it possible, as on the Honor Band 5, for example, to identify cases of sleep apnea and other respiratory disorders.
