Why iPhone does not use USB-C and still use Lightning

USB-C is becoming more and more extensive, many electronic products are beginning to adopt this emerging interface type, which includes Apple's computer equipment, including only a USB-C interface (12-inch) MacBook, There are 2-4 USB-C (Thunderbolt 3) interface, the new MacBook Pro. In the mobile phone and tablet, Andrews camp manufacturers have in their devices on the deployment of USB-C, Apple in the field of mobile devices, still adhere to Lightning. So the question comes, why iPhone is not yet USB-C? Next, let us point a few small points, to Apple and USB-C some of the issues to be explored.

Why does Apple use USB-C instead of Lightning?

We start with a simple point of view to answer this question, Apple from the 2012 iPhone 5 began using Lightning interface, and at that time there is no USB-C. Until August 2014, USB-C was finally finalized.

So why does not Apple wait for USB-C?

Suppose Apple was able to wait until the arrival of USB-C (no extension of the case), it is estimated Apple will take a long time to let the year's iPhone 5, iPad mini and iPad Air are smooth and USB-C compatible, Shen, it is possible that these devices can not be released on schedule, so there is a certain degree of adventure for Apple.

So the time to return to the early release of the iPhone, when the first generation iPhone with a 30-pin Dock interface, which is Apple in 2002 specifically for the iPod to create the interface, but the iPod was very popular and very common, 30-pin Was good enough, then more of a functional needs.

Over time, the 30-pin Dock interface became obsolete and Apple needed something better to replace the 30-pin connector. At that time, USB world is still confusing. At that time there are standard USB-A, miniUSB and microUSB, the latter two can provide advantages in terms of size, because they are relatively small, but this is not enough. Apple hopes to bring some of the more advanced things, some can make them reuse 10 years of things, their goal is not a need to replace the regular replacement.

So, in the USB-C this concept began to be a little familiar with a few years ago, Apple began to study Lightning. Apple initially wanted Lightning to create a symmetrical, easy-to-plug-in, fully digital interface so that it could take on some of the new standards that could come in the future and extend its lifespan. It would also allow Apple to build new interfaces based on that interface device of.

So now, iPhone can use USB-C it?

Apple is free to build iPhone, including the interface into USB-C, but need to consider some issues.

1. USB-C in the interface size is larger than the Lightning, although not much larger, but in the land of space inside the contest, "big" is a big obstacle. The following picture will give you a USB-C interface, the space occupied by a more intuitive understanding of.

2. USB-C is a more open and compatible standard, but at the same time there are restrictions. As for Lightning, Apple can "do whatever they want". This means that if you develop a new technology, Apple can quickly integrate these technologies into their own development of the interface standard, without having to consider the standard agreement to reach a series of issues.

3. USB-C users need to re-adapt, this is the last user to face. The 30-pin Dock connector took 10 years to come to Lightning, and now Lightning has been in use for five years. You know, now there are hundreds of millions of Lightning devices on the market, and Lightning is everywhere.

Is Lightning a way for Apple to control accessory manufacturers?

If the final choice for USB-C to replace Lightning, then the problem came. Lightning licensing chips are mainly used to limit those who are not authorized cables and accessories, if you give up this specification, then Apple's accessories sales will be affected, or at least Apple's control of the accessories ecosystem is weakened.

Apple likes to manipulate everything and be good at making a profit. On the other hand, when you look at the USB-C problems and the fake cables on the market, you might think that Apple's control is actually beneficial.

IPhone will eventually use USB-C?

Apple's Lightning team helped create the USB-C, which is why there are so many similarities between the two reasons, and why Apple will create a USB-C Mac reasons. Perhaps some time in the future, Apple will be equipped with USB-C iPhone, despite the pain of the transition to go through.

The AirPods charging box's charging interface is very similar to the USB-C connector, and we do not know if it's a coincidence, but it may mean Apple wants to use the USB-C interface on the iPhone and iPad. When the day comes, you may not be surprised. USB-C interface has a lot of advantages, perhaps until one day Apple that these advantages are worth enough to allow them to pay the price of transitional pains, that is, USB-C really go to Apple that day.
