According to the latest rumors and speculations of online publications, the next generation of Apple's smartphone will finally receive an impressive screen. Everyone seems confident that the next iPhone 5, which is expected to launch closer to this fall, will feature a 4-inch display.
But while we have heard many theories as to how Apple might come up with such changes, we have not yet heard any explanation regarding their nature. Why is it that Apple suddenly wanted to resize the iPhone screen after 5 years of following the same course? Of course, the simplest explanation is that Apple is making the iPhone screen larger in order to compete with its Android competitors. But given that the 3.5-inch phone is already the top-selling device in almost every country, it really doesn't make sense.

David Pogue, editor of The New York Times, suggests that it has something to do with the battery of the future smartphone. He believes that enlarging the iPhone's screen will allow Apple to use the larger battery needed for various new smartphone features, such as LTE:
David Pogue is really right. The use of 4G technology and the issue of the iPhone battery is extremely important. An enlarged display, a powerful processor, a powerful graphics card and support for the LTE network - the significance of a powerful battery is evident. But if you don't like the big battery theory, then Matthew Panzarino, editor of TheNextWeb, has another interesting suggestion. He believes Apple could introduce a 4-inch 16: 9 iPhone to make it more comfortable to watch high-definition video:
However, in the end, these assumptions are pure speculation. Apple will introduce a large screen in the upcoming iPhone 5, but the real reasons for this innovation will be announced only by the company's management.
