These new iPhone 8 renders reiterate one unusually large power key
While there aren't many differences from similar concept images we've seen drawn so far - the AR-touting vertical dual camera and the all-screen front are still a go - what struck us as interesting is the size of the power/lock key on the right side. It could, apparently, grow up significantly when compared with the current iPhone power buttons. The potential reasons for the increased size may deal with ergonomics, or, alternatively, an extra space to incorporate Touch ID in.
A finger scanner in the power key is not a novel concept, and has been done before, so when we factor in the rumors that Apple is struggling with the idea to embed a new and unproven in-display fingerprint scanning technology in the OLED screen of the iPhone 8, it might make sense that they would leave their options open with regard to the ultimate Touch ID placement.
