The iPhone 11 only came out in September, but there's already leaks indicating what direction Apple could take with its successor. Korean news outlet ET News reports that Apple has been ordering OLED display panels in 5.4 inch, 6.1 inch, and 6.7 inch varities from Samsung and LG for next year's release of the iPhone 12. This would indicate that Apple is looking to change up its three available models for the next generation of iPhone.
The iPhone 11 features a 6.1 inch LCD, while the iPhone 11 Pro has a 5.8 inch OLED screen, and the 11 Pro Max has a 6.5 inch OLED. The report suggests that the next iteration of the Pro will sport the 5.4 inch display in a size decrease, while the regular iPhone 12 will feature a 6.1 inch display and the Pro Max a 6.5 inch one. So not only will the biggest iPhone be getting bigger next year, but the smallest will be geting just a little smaller.
Earlier this month, the first leak for the iPhone 12 happened when renders of the phones appeared online. The renders showed the phone going into a slab-like design similiar to the fourth generation of iPhones, while it also sported smaller notches from pervious years and a quad-camera on the back. Of course, everything here is far from confirmed, but it would point toward a bigger technology jump than last year's iteration.
