Apple might ditch the white plastic antenna strips that are found on the back of the current iPhone 6S and 6S Plus on the next iPhone, according to Chinese news site, Commercial Times. (Via Mac Rumors.)
Instead of the white plastic strips on the back, Apple might use "new compound materials" that would be less noticeable, or even invisible, to allow cellular signal to transmit properly.
The white plastic strips on the back of the current iPhones serve as antennas for the cellular signals. Without the strips, the current iPhones wouldn't get nearly as much signal because cell signal doesn't transmit through metal as well.
The strips were also a point of contention when iPhone revealed the iPhone 6 and 6 Plus, which were the first iPhones to come with the strips. Some people thought they were ugly and ruined the looks of the iPhone.
The same Commercial Times report also mentions that the so-called iPhone 7 might also be more water-resistant than the current iPhone 6S and 6S Plus, which Apple already quietly built to be surprisingly water-resistant.
