For the upcoming iPhone 16, Apple will adopt the same color-infused back glass that features on the standard iPhone 15 models, claims a new rumor out of China. Last year, Apple debuted a custom dual-ion exchange glass process on the non-premium iPhone 15 models that gives the rear glass layer a frosted effect that contrasts with the main frame color. Apple's description of the effect on the iPhone 15: "For the first time in a smartphone, colour is infused throughout the back glass, creating five beautiful colours. The back glass is strengthened with an optimised dual-ion exchange process before being polished with nanocrystalline particles and etched to create a luxurious, textured matte finish." According to the Weibo-based leaker "Fixed focus digital," who claims to have seen the iPhone 16 color scheme , Apple will use the same process for the back glass on the new models, which could come in as many as seven colors this year as opposed to five. iPho
