iPhone X vs iPhone 8 vs iPhone 7: Should We Upgrade?

Upgraded iPhones – iPhone X/iPhone 8/iPhone 8 Plus

 
The three updated iPhones this year are the slick all-screen iPhone X, the latest iPhone 8 and 8 Plus, made available with wireless charging.

 

How does the latest iPhone tend to differ?

 
The iPhone X has a different appearance in comparison to the other iPhones. It’s more like the Essential Phone and the Samsung Galaxy S8 though with an increase in screen-to-body ratio. On slimming down the bezels and eliminating the home button, Apple seems to have packed a 5.8-inch OLED display in a reduced body than the iPhone 7 Plus together with the iPhone 8 Plus. Towards the top of the display is included an IR camera, for the front facing camera together with an array of sensors - `Dot Projector’ and 1Flood Illumination’.

Moreover, Apple has also switched the aluminium frame utilised from the time of iPhone 6 with a glass back though has maintained the comfortable curved edges that are now of `medical grade’ stainless steel on the iPhone X. Regardless of the claim of Apple that the glass tends to be most durable in a smartphone, glass tends to be a fragile material which would mean that the user would not only have to cope with the likelihood of cracking the display when the phone tends to fall but the rear as well.

At first glance, iPhone 8 and iPhone 8 Plus tends to look similar to the iPhone 7 and iPhone 7 Plus which seems to appear like the iPhone 6, with chunky bezels together with home button/fingerprint reader. Apple has also included a glass back to the iPhone 8 and iPhone 8 Plus which tends to make it more delicate than its precursors.
 

What is the size of the iPhone X in comparison to other phones?

 
Some users have the penchant to the tiny, easy to use one hand dimensions. The amazing news is the `no bezel’ design which shows that the iPhone X is somewhat the same to the iPhone 8 than the Plus irrespective of its big screen. With regards to statistics, the iPhone X is said to be about 5.2mm taller than an iPhone 8 though the iPhone 8 Plus tends to be a substantial 14.8mm taller than the iPhone X. Moreover the iPhone X also tends ot be the same size as the Samsung Galaxy S8.
 

How does the iPhone X tends to work without a home button?

 
In order to get to the Control Centre, user could swipe down from the top of the screen towards the left, swiping down from the right side opens the notifications. These are small changes and not too complex. TouchID that are in-built in the home button have been replaced by FaceID on iPhone X tough TouchID tends to remain on the iPhone 8 and 8 Plus.
 

What is Face ID?

 
Since the home button has been eliminated from the iPhone X together with the fingerprint sensor by Apple, it has come up with a standby in the form of Face ID which is a facial-recognition security process enabling the user to unlock their phone with their face. Face ID, unlike Samsung’s Galaxy Note 7, utilises the new depth sensing camera of iPhone X for verifying the features which means that it is unable to be fooled with an image, the way the system of Samsung tends to do. It functions by utilising a `Flood Illuminator’, which provides adequate light for infrared camera as well as `Dot Projector’ for firing `30,000 invisible IR dots’ at one’s face. Thereafter the IR image together with the dot pattern is moved through neural networks for the creation of mathematical model of the face and is then matched to a stored 3D model. The information related to facial is protected by same `secure enclave’ utilised by TouchID while at the same time the data processing is carried on-device rather than of the cloud. Apple has stated that its tech is good enough for FaceID to function in the dark and also if one intends to improve on their looks like grow a beard, wear glasses etc. It’s left to be seen if FaceID would be living up to the promises made by Apple.
 

Should we care if iPhone X has OLED screen?

 
The iPhone X is said to be the first phone of Apple to have OLED display though Samsung had been utilising the same in its devices for several years. Apple’s IPS LED displays utilised tend to be good though OLED technology enables richer colours together with deeper blacks which is owing to the ability of turning each single pixel on or off whenever required. Considering stability, OLED seems to be a good upgrade due to its fantastic contrast of OLED screens which seems excellent for videos as well as photos and this is the reason people prefer an OLED TV. Hence it is good news that Apple has made the switch even though it has come up with this idea a bit late.
 

Are the latest iPhones faster?

 
The iPhone X and iPhone 8 features a new six-core A11 system-on-a-chip –SoC, comprising of four low-power core together with two performances cores which tend to build on 10nm FinFET manufacturing system rather than the 16nm process of A10 Fusion in the iPhone 7. Apple, on decreasing the process, has filled more transistors in a smaller space enhancing the performance as well as the battery life. Apple has claimed that the iPhone X has the potential of lasting for two hours longer on a charge than the iPhone 7 as well as it is 25% faster on performance cores and 75% faster on the energy efficient cores. In the meanwhile Apple has created its own Graphics Processing Unit – GPU for the A11 SoC breaking off with Imagination Technologies. Both the iPhone 8 and 8 Plus tends to have the same A11 SoC like the iPhone X. But the A11 seems to be a tough sell if one is a user of iPhone 7 and are also new to the features.

How Face ID Works On iPhone X

Face ID
After months of waiting, rumors and scandalous leaks in macmyth.com, the iPhone X is now here. With it comes Face ID, the new method of user authentication that replaces Touch ID. The fingerprint gives way to us as an element to unlock the terminal, confirm purchases in the App Store or verify payments with Apple Pay. How exactly does this system work? Macmyth.com is here to explain everything about Face ID in iPhone X.

Firstly, Face ID is a system that uses a front camera and an infrared camera, as well as a support light and an infrared projector. This means that the iPhone X not only sees a front camera, in two dimensions but also does a three-dimensional recognition that detects the depth of the faces, as well as the extensions between factions: distance between eyes, shape, and size of the face. nose, etc.

Face ID emits 30,000 invisible infrared dots that help rebuild the mathematical model of the face that has been built. If an unspecified quantity matches, proceed to verify the user. This is interesting because it is a high enough amount to be able to detail and leave out mismatched elements that are very easy to change in a face.

For example, if one day we put on glasses or we change the ones we already have, if we go to wearing sunglasses if we make up if we leave a beard or shave, if we wear a hat ... All these variations, according to Apple, are controlled and will not be a problem when checking with Face ID.

A processor designed for Face ID


This verification takes place in real time thanks to the new processor, Aion Bionic. It brings a neural motor that uses neural networks and machine learning to adapt to the facial variations. We discussed before and learn what changes in the face of the user to anticipate as well and to be able to carry out the verification. Face ID can reach 600,000 million operations per second while processing the images it obtains by "looking" at the face. It's specific hardware to help facial recognition system, the new cornerstone of iPhone X.

According to the tests that Apple has spoken, Face ID cannot be deceived by photos, 3D facial molds or other forms of impersonation. Although he has not specified how he will achieve the latter (depth-first), he may employ life-sensing mechanisms common in advanced facial recognition systems.

In any case, it will also require attention. That is to say, in order to unlock it, you will need to be looking at the terminal, it will not be enough to be looking at something nearby or distracted, a measure designed to prevent accidental unlocking.

Apple has also explained, according to its evidence, the probability of obtaining a false positive. That is the probability that someone other than us will be able to access the terminal. For Face ID, it is a possibility between a million. Something far superior to what the Touch ID offers (one in 50,000) and of course the four-digit PIN lock (one in 10,000, that is, each combination between 0000 and 9999).
