Pictures of Fitbit Charge 4 have recently been leaked online, and the latest model looks a lot like the earlier version of Fitbit Charge 3. A retail listing and an FCC listing first showed the images of the newest Charge 4, and both of those listings have been deleted now. The listings also offered a bit of insight into a couple of details about the fitness wearable. The colors of the wearable shown in the images were rosewood and black. The rectangular design of the screen and the pattern on the straps at the wrist are all similar to Charge 3.
‘9to5Google’ was the first to share these images that showed the back and front sides of Charge 4 in both the color options. The logo of Fitbit sits right below the display and appears to have been done in greyscale. The multiple sensors at the back, going by the reports, include a relative SP-O2 sensor and an optical monitor for heart rate. The cutout on the case further suggests that the fitness wearable might also come with an altimeter.
Reports suggest that, just as it was with Charge 3, you can swap out the watchbands easily in Charge 4. Going by the pictures, the dimensions of both are the same, and in that case, you can use the straps of Charge 4 on Charge 3 too. However, there might be a Granite, Black, or Storm Blue special edition for the Charge 4.
The FCC listing that came with the ID XRAFB417 suggested that the latest device will come with NFC and Bluetooth, which is good news because NFC support is only available on the special editions of Charge 3, at present. The listing might be for Charge 4 special edition, or maybe now there will be NFC on all models.
