There have been a ton of rumours about the iPhone 8. The previous rumour, from Japanese Blog Macotakara had said that the iPhone 8 would be the only iPhone to receive wireless charging in 2017. The report also stressed that a separate adapter had to be purchased to charge the iPhone 8 without wires.
Sur mentions that the iPhone 8 will adopt a glass back, as has been by numerous reports. The expected glass back of the iPhone 8 reportedly reduces interference versus the metal back design. Furthermore, Apple is reportedly working on “proprietary features” including things such as fast charging and extended charging.
However Sur noted that there’s still a possibility that wireless charging won’t be included in the iPhone 8 due to increased concern about safety following the Galaxy Note 7’s Saga.
