Dickson said on Twitter that the iPhone 6 will be just 0.22 inches thick (or around 5.58 millimeters), and that it will pack an Ultra-Retina screen with a pixel density of 389 pixels per inch (ppi). He also said the phone will pack an A8 processor clocked at 2.6GHz.
“These specs could be the real thing,” Dickson added, without specifying his source or revealing other details about the handset.
For comparison, the iPhone 5s has a 4-inch display with 1136 x 640-pixel resolution and 326 ppi, a 64-bit A7 processor clocked at 1.4GHz and an M7 motion coprocessor. It’s already incredibly thin at 0.30 inches (7.6 millimeters) thick, so a 0.22-inch iPhone would be insanely thin.
