The device is removable from its wristband, which makes it easier for users to customize it with an additional band. The bottom half of the fitness tracker features the heart rate sensor along with the charging connector. Since there are no screws on the Gear Fit, access to its innards is only feasible by removing the screen assembly, which is held on by adhesive. The screen assembly is attached to a motherboard that is segmented into three sections to accommodate for the curved nature of the Gear Fit. On the motherboard are the Wi-Fi and Bluetooth 4.0 LE receivers in addition to the flash memory and the CPU. All the internal hardware is soldered onto the motherboard.
The device on the Gear Fit is a curved 210 mAh offering that can last for three to four days. The battery itself is encased in a shroud behind the motherboard. The battery is one of the few things you can change in the Gear Fit, but to do so you have to remove the screen assembly and the motherboard. Overall, the Gear Fit scored 6 out of 10 on iFixit’s scale.
