At the end of the 20th century, only a wealthy person could buy a mobile phone – an official, a successful businessman, or anyone else. There were no difficulties in choosing then, since five or six cell phones were produced annually. But gradually the cost of production fell, as a result of which mobile phones literally flooded stores selling electronics. And with the advent of smartphones, everything has become even worse – these are technically complex devices, in the intricacies of the structure of which not every person is able to understand. If you can’t choose a suitable smartphone for yourself, then check out our article – it will certainly help you.
The principle of operation and the device of a smartphone
A modern smartphone is the same computer, but in miniature. It uses a tiny processor based on ARM architecture, which consumes not too much power and generates almost no heat. Information is processed by the device not only with the help of the processor, but also with the help of RAM – the more it is, the more applications can run in the background. User data (photos, music, games, etc.) is stored in permanent memory. They can also be stored on a memory card, but not every smartphone has a slot for it.
Autonomous operation of such devices is provided by the battery. It can be made using lithium-ion or lithium-polymer technology – this does not play a big role now. But it is worth paying attention to the battery capacity. However, the duration of work depends not only on this parameter, but also on the technology used to produce the display and what resolution it has. And each processor also has its own level of power consumption.
Varieties of smartphones
Many devices are very different from each other. However, it cannot be said that there are a large number of varieties of smartphones. Most often, such devices are divided into three parameters.
Form factor
The vast majority of smartphones sold now belongs to the mono block form factor. This is a familiar bar made of plastic or metal, most of the front panel of which is occupied by an LCD display. But devices with a completely different design also have some popularity. For example, in Japan you can still buy the so-called clamshell. Such a device consists of two halves. Most often, it has two displays.
Such a device may also have a numeric keypad, with the help of which a telephone number is dialed or some other actions are performed. And in some stores, you can still find QWERTY smartphones. Basically, their design is engaged in the company Blackberry. Such devices have a physical QWERTY keyboard. Sometimes it works on a retractable principle – this turns the smartphone into a slider.
Approximate price and power of components
Since almost all modern smartphones are mono blocks, people and companies prefer to divide them by power and estimated cost. For example, telecom operators sell ultra-budget devices under their own brand. Even pensioners can overpower their purchase, but such a device will regularly slow down due to lack of power. About the same can be said about budget smartphones, which are also inexpensive.
A huge number of smartphones belong to the middle or, as it is also called, the mid-budget price category. Among all this assortment, you can find real emeralds that will delight with their work for many years.
Well, the so-called flagships bring the most money to companies. They have support for almost all modern technologies, and some of them have some completely new components. For example, in the spring of 2017, Samsung introduced an iris scanner into its flagship, which no smartphone could boast of before.
Operating system
The last sign of the division of smartphones. Android dominates here – the largest number of devices work under its control like HONOR 50. At the same time, we leave out the version of the operating system, we will talk about it below.
The second place in the popularity rating of operating systems is occupied by iOS – it is preinstalled on every iPhone.
It was never able to achieve a significant share in the Windows market in various implementations – it is not recommended to buy smartphones with it now, since Microsoft may soon stop supporting the mobile version of this operating system.
Conclusion
It is important to look at the features of a smartphone as it is an important decision of your life to buy a smartphone. So, look deeply before buying one.
