Contrary to previous reports, the battery isn't directly accessible, or easily removable at all. One must remove the middle frame first, then take out the NFC chip and unscrew the motherboard in order to get a shot at replacing the battery. It is a 3.85v 9.82wh 2550mAh li-on unit, and we're very curious if this capacity is enough to ensure a long battery life for the GS 6.
The technician also noted that the camera module has been equipped with a fixed base to help against producing unwanted jitter.
There isn't much more in the way of notable details, but the Galaxy S6 does seem well put together. You can also check out a pretty shot of the Exynos 7420 SoC, commander in chief of the Galaxy S6's processing department.
