According to a source for Nikkei, Apple will be rolling out 3 different iPhones next year. Two will have OLED displays at 5.8 and 6.1 inches. This follows Apple’s past strategy of an iPhone and a Plus model. The third will be metal backed with a 6.1 inch LCD display. This is in line with Apple’s past lower-cost offerings with the iPhone 5c and iPhone SE. With a metal back, the LCD model is unlikely to have wireless charging.
