As schematics of Apple's forthcoming trio of iPhone handsets leaked onto the web a while back, the inevitable has happened and we're seeing an increase in leaks of 3D renders based on those schematics, and also physical dummy models which bring them to life in the real world - except they don't actually function, of course.

Most of this stuff is produced by case makers, the latter in particular because it helps them create accessories well in advance of Apple's expected September announcement.

And even though they don't power on or showcase some of the hardware and features, they do still give us a good idea of what to expect in terms of design. Some features are also indicated by certain physical design choices, of course, such as the number of camera ports, display notches, and so on.

A couple of video showcases have now been posted online showing these dummies for all three of Apple's 2018 iPhones in minute, hands-on detail.

One such video comes from prominent tech Vlogger Marques Brownlee, while the other comes via a Youtuber called Dravid Sajin.

In both videos there are a couple of mistakes or speculative assumptions about the iPhone names, as at this stage we really don't know what Apple plans to call the new devices following the iPhone X. There are a lot of different theories fighting it out right now.

The main thing we do know for certain is there will be three of them, as shown in both videos, ranging from a 5.8 OLED-screened iPhone X successor, a 6.5in OLED "iPhone X Plus", and a 6.1in LCD-screened iPhone which is beleived to cost less, in the vein of the iPhone SE, but much larger.

All of them feature iPhone X-style design language, including the display notch and lack of a front physical key, with 3D face scanning, aka Face ID believed to be taking the place of Touch ID on all models.

The phones are expected to be launched at an event in early-to-mid September and then released to market within a couple of weeks, likely within the same month. However, rumours persist that the LCD model may be delayed until November due to screen manufacturing issues; whether that means announcement or just release is unclear.

Depending on how Apple prices the phones this could all be for nought, of course, with the company not seeing the best sales of the iPhone X due to many consumers refusing to pay in excess of $1000 for a smartphone regardless of what bells and whistles it has onboard.
