Ten years ago, there was no guarantee that the iPhone would succeed. But, it turned into almost the most popular gadget in the world. At the time, the iPhone was radical, meaning that nothing like that didn't exist in the market. Even the design, which was not "boxy", stood out from the competition. Over time, the iPhone has developed his own way, which only its creators understand. In fact, this device is form the start followed by the stigma that despite its expensiveness (among the highest price class) users don't have the feeling that they are getting the most technologically advanced device with all available options and innovations. Often it was correct, but the iPhone is a brand that is difficult to break and because of that, the "dosage" of new technologies became widely accepted.
In the beginning, The iPhone wasn't smartphone at all. With the development of the App Store, he could get a superior device characteristics adapted to everyone. Although, there were some controversies here, because of the limitations of performance, and types of applications. Everything was quickly solved and the App Store is now one of the most used applications store in the world.
In this topic, we will briefly show all the most important things related to each model iPhone (total of 15 models). While doing it, we will put emphasis on the key features and events that have marked them. Of course, by reading these lines, you can follow the development of each model, and, finally, compare the first and the last model, and see the progress of technology in the last 10 years.
This was the first smartphone that had a capacitive touch-screen, which is small by today's standards, but then it was twice as large as any other. It had a resolution of 320x480 pixels, which is unthinkable in today's terms, but it needed to start from some point. It had 4 or 8 GB of memory and Samsung's 32-bit ARM core.
Despite that, the first iPhone was limited. It did not have 3G support, and there weren't a lot of telecom operators to whose network it was compatible (for example, in the USA only AT&T could sell iPhone). The device was actually quite distant from the users, the keyboard on the screen was not as good as physical keyboard (something that has not changed much), and it was also quite expensive compared to the other devices, which offered more features and greater flexibility at that time.
The biggest advantage of this model was that it finally supported 3G network. In addition, the metal casing has been replaced with plastic (that's a shame, because it means that the unit was more sensitive to shocks), and improved compatibility with headphones (a problem that Apple has today). Memory has been increased to 8 or 16 GB, and thanks to the 3G support, the above mentioned Samsung processor was giving better results.
On the other hand, iPhone 3GS was twice as fast as 3G, thanks to the significant progress of the main and graphics processor. In fact, this was the first iPhone that used the ARM Cortex-A core and PowerVR graphics. Of course, the memory was increased up to 32 GB, and the first cases of overheating batteries were reported, because it still was not able to follow the progress.
iPhone 4 was in many ways revolutionary. It was the first smartphone with Retina display, the first with Apple's chip, the first to gain power antenna, the first with front and rear camera, but the last with a uni-core processor.
iPhone 4S will be remembered by the fact it was presented on the day when Steve Jobs passed away. In addition to this inconvenient fact, 4S boasts better graphics, support for HSDPA+ (weaker version of 4G) and Siri virtual assistant.
iPhone 5 was the first real response to the madness that engulfed the market, caused by the Android OS. Screen size has for the first time exceeded 4 inches, the LTE (4G) support was added, just as the Lightning connector, and the first processor made by Apple. The difference between the "fiver" and 5C is in a plastic housing with more colors added.
Well, a little more differences had the model 5S which first introduced TouchID fingerprint sensor to unlock the phone. It was the first 64-bit smartphone, and had an updated version iOS 7, which was significantly different from the previous ones. iPhone SE were actually a repackaged 5S.
iPhone 6/6 Plus/6S/6S Plus
iPhone 6 was the first attempt of Apple to attack the large smartphone segment, and it was the first device with 1GB of RAM. It turned out popular, but rightly criticized because of serious flaws in the design, construction, and manufacture, which have led to frequent failures and shortcomings. Apple was aware of the errors, but their nonchalance ruled out to put the thing on the market. The same thing had happened with its bigger brother, 5.5-inch 6 Plus.
6S brought progress in the construction, as well as a faster processor and better overall performance. In addition, it introduced a haptic interface, and "even" 2GB of RAM.
iPhone 7/7 Plus
The iPhone 7 has a similar situation as with the "six", at least as the addition of the Plus model is concerned. Of course, it hasn't the same complications, although there were initially some problems. The biggest objections are related to the removing of physical Home button, and standard 3.5 mm headphone jack. Apple calls it a revolution, no matter that everyone, including me, consider this move as a foolish. The new iPhone also has a first quad-core processor with a combination of faster and slower cores, and the latest iOS 10.
The future of the iPhone
There are a lot of rumors about the possible features of the iPhone 8. Some were very meaningful, such as a ceramic housing, but some would be desirable, for example an OLED display (which is much more efficient than the LCD or Retina), and wireless charging (still fashionable, but useful detail). The story about the new 10-nanometer chip also has emerged. It should help to reduce energy consumption and increase battery life.
But these are only rumors for now. Whatever new iPhone 8 (let's say it will be called like that) will offer, it will not be as revolutionary as 10 years ago. The evolution of smartphones has slowed a lot, although a growing number of tasks that can be done. Large companies, including Apple, have moved themselves to the smart wearable devices market, predicting their even brighter future (at least now, there is no way for such thing). We can only say that we can't wait until October, and the revealing of the new version of the icon of modern communication technology.
