Apple iPhone 8

The iPhone 8 is 138.4 x 67.3 x 7.3 mm. Above the 4.7" display, there is a facetime camera and a couple of sensors. There is no headphone Port; you have to shift to wireless. The power key and volume keys are placed on the right and left sides of the handset. And the fingerprint scanner is located at the bezel.

With the recent upgrade of all glass over front and back, Apple says that "it is the most resistant glass ever made in smartphone history." The rear glass enables wireless charging. The iPhone glass finishes with a seven-layer colour process and aluminium design makes it unique and resistant to scratches and fingerprints.  

The front design looks bezel heavy and looks identical to previous generations, which makes it outdated. It is splash, water, and dust resistant and available in three new brand colours: New space grey, silver, and gold. 

AR:  It is the world's largest platform for augmented reality, and you can experience mind‑blowing AR games powered by A11 Bionic. 

CPU: The A11 Bionic is the dynamic chip ever made in a smartphone that features a faster CPU. Compared to the A10 fusion of previous models, the four efficiency cores perform up to 70%, and two performance cores perform up to 25% faster. The performance controller harnesses all six cores simultaneously, providing more power and excellent battery life to customers.

GPU: The three‑core GPU newly designed by Apple for the first time is up to 30% faster than A10 fusion. The power drives the tasks smoothly.

AR:  It is the world's largest platform for augmented reality, and you can experience mind‑blowing AR games powered by A11 Bionic.
