Byte, a UK-based retailer that sells Apple-certified accessories and parts, recently posted a video in which they showed off a few supposedly genuine parts for a second-generation Apple Watch, including a thinner OLED Force Touch display and a significantly thicker battery potentially giving the wearable device a few more hours of run time.
Today, Byte published precise measurements for the above components and the numbers lead to the conclusion that Apple may have been able to squeeze in a much more powerful battery without making the Apple Watch 2 any thicker.
