The Charge 5 captures movements with a three-axis acceleration sensor. In addition to the optical heart rate sensor, which is mandatory for wearables, the sensors now also include a skin temperature sensor as well as red and infrared sensors to monitor the blood oxygen saturation (SpO2). The reason for this might be the EDA scan, which is a health function that needs two sufficiently large contact areas on the case. In its accessory program, Fitbit offers additional colors, sports bands, and leather bands from Horween.įitbit had replaced the button on the side of the Charge 3 with a sensor key in the Charge 4. As before, two different band sizes are included: S for a wrist circumference between 130 and 170 mm (~5.1 - 6.7 in) and L for 170 to 210 mm (~6.7 - 8.3 in).

Fitbit replaces the hard resin bands of the Charge 4 with softer versions made from silicone in the Charge 5. The case is made from aluminum, glass, and resin.
