Design Reviews: Difference between iPhone X, iPhone 8 and iPhone 7

The iPhones are currently in the 10th iteration, and it has grown from that the small, squarish ice cream bar to a beautiful and sexy design in the new iPhone X. It might not the first phone in the market to introduce some of its “new” features, such as OLED screens, doing away with the Home button and bezel, and facial recognition technology. Unlike earlier, where Apple was the first to use the Nano SIM in the iPhone 5 in 2012 and dropping the 3.5mm phone jack in favour of the wireless earphone. The only “breakthrough” now is probably because the changes are new to “pure” Apple users, but not entirely new in the market per se.

iPhone X was initially announced on 12 September 12, 2017, and Apple officially released the phone for sale on November 3, 2017

This model of the iPhone is unique because it marks the 10th anniversary of the iPhone series, whereby the “X” in the iPhone X is the Roman numeral symbol for the number “Ten”. We are wondering if the next iPhone would be called the iPhone XI for “eleven”.

If you are thinking of upgrading from iPhone 7 or 6 to iPhone X, this review gives you a quick overview of the key differences:


The iPhone “Plus” series have been using the 5.5″ diagonal LCD Multi-Touch screens with IPS, since it was first introduced in iPhone 6 Plus. However, iPhone X now comes with a larger screen size of 5.8″ diagonal OLED Multi-Touch screen. On top of that, it has a higher resolution of 2436×1125 @458 ppi, as compared to the older 1920×1080 @401 ppi in iPhone 6S Plus to iPhone 8 Plus. Apple call this the Super Retina HD Display, and it also comes with 1,000,000:1 contrast ratio, whereas the rest of the iPhone (including iPhone 8) has 1300:1 ratio.

What this means is that you will get a significantly better screen as compared to the all the earlier versions including iPhone 8. Although both iPhone 8 and iPhone X comes with the new True Tone Display and 3D Touch, the iPhone 8 still has the same resolution as its predecessor.

This improvement in screen could be a good reason to upgrade. It may take some time before all the apps are updated to take advantage of the new resolution, however, there should be noticeable differences in videos and photos on the new iPhone X based on the new design specifications.


By reducing (or removing?) the bezel (the surrounding black area around the screen) of the iPhone X, this allows the phone to have a larger screen but a smaller overall size of about 9% in both length and width. It is slightly thicker than the earlier phones but still remains under 8mm. It is also lighter at 174 grams only.
