Over the years, worked for Apple to improve each version of the iPhone, but mostly, the focus of Apple is less on technical detail and more emphasis on the main features, but that doesn’t mean she didn’t made changes under the hood.
In fact, according to the test conducted recently by the company OpenSignal, I have decided to learn how improved speed of communication, cellular phones, and iPhone over the years. According to the findings, the good news is that Apple tend to improve the speed of the cell phone every new model of iPhone is launched.
There are some exceptions, such as the iPhone and SE which was released in the year 2016 which was in fact slower compared with the iPhone 6 and iPhone 6 Plus, which were issued in the year 2014. There are also iPhone XR which runs the device at a speed slower than the iPhone XS and iPhone XS Max, but this is expected due to the differences in the antennas used.
Of course, when it comes to speed communications cellular, there are many things that can affect them. For example, can influence to poor coverage on the speed of the cell phone in your smartphone. May be affected by the speed and also the number of people in the region who use the same cellular network, etc., so you must take these things into consideration while looking at these numbers.
