Both slippery and fragile. The reason behind the iPhone glass design

iPhone back glass very heavy, flimsy and reduces the color tone. So why does Apple keep making them? GhienCongListen Now share interesting facts for this design. Surely you will be surprised by the reason behind that.

With the first versions, the back of the iPhone was designed with aluminum and plastic. From the iPhone 4, the design is changed with a steel border and a glass back, leading to a design style that is somewhat heavy and fragile. It seems that Apple has redefined and streamlined the design for the iPhone 5,6 and 7 with lightweight, thin but sturdy aluminum. But from the iPhone 8 onwards, we return to the glass back paradox.

What’s wrong with glass?

The biggest problem here is that glass is fragile. If your iPhone screen is cracked, you can feel the crack just by touching it. If it’s the back, you can barely feel it, so you can choose to ignore it or cover it with a case, right? But it’s better not to break anything.

Changing the back glass is also very complicated. Depending on the model, you may have to completely disassemble it to replace it (unless there is a mechanical intervention).

Blog Broken Back Glass The back glass of the iPhone 8, X, XR and 11 series is designed firmly with the case and internal components of the phone. Apple uses epoxy glue and small solder joints to attach the circuits and components to the back. Therefore, replacing the dorsal canal is very complicated and even more difficult than replacing the screen.

Another disadvantage of glass is its weight. Not only heavier than plastic, but also heavier than thin aluminum. Combined with the steel bezels of high-end iPhones since the Xs, this design is considered heavy and bulky.

And finally about the aesthetic factor. For example, the red iPhone 12 is delicate and vibrant with an aluminum finish. But with the glass back, the color becomes faded. The top glass doesn’t look too bad, but the matte coating of the Pro version is quite slippery. Adding the back cover is too heavy.

So what is the reason for the iPhone’s back glass?

The only reason here for the iPhone’s back glass is the Qi charging feature, aka wireless charging. Qi chargers use induction to transfer power to the phone. The metal back won’t accommodate this feature, although plastic can also solve the problem.

In addition to the requirement that the transmission material is glass, Qi has many other disadvantages. The feature is inefficient compared to direct charging and will decrease efficiency if you do not place your phone in the charging dock. You also cannot hold and use the phone while it is charging. Too inconvenient compared to wired charging right?

This is a subjective assessment, but at a macro and global level, this especially affects the environment. While Apple has stopped putting USB chargers in iPhone boxes for environmental reasons.

Comparing Qi and the new Magsafe technology for iPhone 12, charging the iPhone 12 seems to be inefficient. If you are a person who is not very fond of glasses, prepare to live with cracks or simply buy a case.
