How has iPhone evolved, internally

Let’s be honest, the appearance of new iPhone is less stunning as they were compared to a few years ago. Except the infamous “notch”, not much design cue changes have been made from the technological giant since, sadly, the death of Steve Jobs. The “iPhone cycle”, which there would be a major design change every two generations, was recently broken as well.

However, despite lesser of a change on the outside, more changes happened on the inside. Brought to you by On The Go which provides iPhone repairs in Melbourne, we are going to explore the “organs” of i Phones.

The screen

This one might be the most visible “internal” change made to iPhones. As the key component for users to interact with the device, the screen has gone through some major changes over the years. The most notable would be the “retina” screen first introduced on the iPhone 4. Advertised as to match every reception cell in human eyeballs at a normal viewing distance for the truly no alias viewing experience, “retina” was revolution at the time. The 326ppi pixel density soon became a benchmark for screens that other manufacturers tried to catch up.

However, it was not until the iPhone X when OLED screens finally appear on iPhone. Being adopted in other smartphones, Apple was some of the latest to embrace the technology. Yet, the screen also arrived with the notorious “notch” that made the world’s first “all-screen” iPhone, with the removal of fingerprint sensor of course.

Touch ID

I would not say it was a forgotten gem as most would still want the return of Touch ID to i Phones. Introduced with the i Phone 5 S, the home button of i Phones (if you know, you know) were embedded with a fingerprint sensor for bionic unlocking.

The “virtual” home button on iPhone 7 that took away the physical press with a fake haptic vibration to simulate a press saw Touch ID as a key member for the unlocking experience, as the pressure sensor was embedded with a fingerprint sensor.

Sadly, giving way to the “more advanced” Face ID, the fingerprint sensor in iPhone was replaced, though multiple reports have mentioned that Apple might bring back fingerprint unlocking with an under-screen sensor.

The battery

You might wonder that I mentioned battery when iPhone is known with subpar battery life. But Apple actually did hear our far cry. In the iPhone X, there is actually two batteries in the phone. Despite the dual battery did not offer huge increase in capacity, it has shown an initial step from Apple to finally maximizing the space within the thin body for more battery.

Despite not mentioned, I believe the idea was originated from the Mac book line up, as the fading thickness of the laptop had Apple stacking batteries together to fit more battery to its form.

The board

The reason behind the battery change was because of none other than the stacking logic board. In order to maximize the thickness of the phone, Apple stacked two logic board in the iPhone X to create one of the most-dense logic unit in electronic devices, even more dense than the Apple Watch.
