The schematics were published in Mac Fan's June 2016 edition.
There is an article of the same exact size of design draft of so called iPhone Pro(5.5-inch) which has 5.5 inch LCD display in Mac Fan June, 2016 edition. According to the article, the size is 158.22 x 77.94 x 7.3 mm, and dual lenses will be introduced to iSight camera. The size itself is identical with iPhone 6s Plus, but there isn't the hole for head phone jack plug any more at the bottom.
While we are unable to confirm the authenticity of the schematics they do match up with previous leaks. It's been rumored that the iPhone 7 will feature a dual lens camera (Plus model only), simplified antenna bands, no headphones jack, and possibly a Smart Connector.
Yesterday, a new report predicted that the iPhone 7 could be waterproof and dustproof; as well as, feature a new touch sensitive home button.
