The choice of a cell phone depends on many criteria. How to choose exactly what you need? The answer to this and some other questions is already ready.
To begin with, let's define with. Here the assortment is divided into 2 categories:
-Mobile phone.
The device is already familiar to most of us. The main differences will be in the manufacturer, the shape and color of the case, and some functions.
-Smartphone.
This is more than just a mobile phone. The smartphone has its own operating system. This significantly expands the list of installed programs, additional functions for almost every taste. Smartphones are very popular today, the choice here is wider.
If the device is intended for a child or an elderly person, then you should pay attention to simple models of mobile phones with large keys, good screen backlighting and a minimum of functions.
As soon as the choice with the class of the device is made, we proceed to the choice of the case. There are also several options here:
- Monoblock. This is a classic among cell phones. Differs in reliability due to the absence of moving elements.
- Slider. The body has two parts, one of which extends upward. The size is compact, the screen is large enough compared to the candy bar.
- Folding bed. The peak of its popularity has already passed and is smoothly becoming a thing of the past. Nevertheless, it has its own circle of users, that is why the majority of manufacturers still keep clamshell models in their lineup.
The main thing here is your convenience. Each of the proposed control systems has its own fans.
The touch screen has a larger area, control is carried out with the help of fingers, as well as with the help of control buttons (usually from 1 to 3, and in modern models they may be completely absent). It should be noted that the touchscreen uses more power, which means that the battery will drain faster. In cold weather, the sensor may not respond well to touch. Also, the touch screen needs a protective film. It is recommended to purchase and stick it immediately upon purchase in order to save the screen from scratches.
in turn are divided into:
Capacitive - a more modern and convenient type of screen. Reacts exclusively to touching with fingers or special stylus (ordinary ones are not suitable).
Resistive - responds to touch with any hard object (a stylus is included, but you can also use a pencil).
Resolution and are also important for good clarity and image.
The high resolution of the screen guarantees a clearer picture.
Image quality depends on the type of screen. There are a lot of them, I will give only a few of the most popular:
TFT, TFD - are distinguished by a sufficiently high clarity and contrast of the image, good screen performance. The disadvantage is high power consumption.
IPS and S-IPS are one of the varieties of TFT screens. Here the viewing angle and reaction speed are increased. They have perfect black color and good color rendition.
OLED - high contrast, brightness and energy efficiency. These displays are significantly thinner than others. The cost of smartphones with such a screen is quite high.
AMOLED is a more advanced OLED technology. Accordingly, more expensive.
The most popular operating systems these days are:
IOS is an operating system exclusively from the manufacturer Apple (iPhone).
Android - this OS is very popular and most manufacturers release smartphones based on it. Updated frequently enough.
Windows Phone is a familiar interface from Windows. Slightly less options for installing programs and applications.
BlackBerry - this operating system is used only in smartphones of the same name. Accordingly, less common than the previous ones.
There are also some other operating systems such as Symbian, Samsung Bada and others.
Battery
A smartphone always consumes significantly more power than a mobile phone. Autonomous work of a smartphone is usually about a day. Therefore, the battery must have a large capacity. The higher it is, the longer you can use your smartphone without "recharging".
CPU
The performance and speed of the smartphone depends on the type and speed of the processor, the number of cores. The higher these numbers, the more powerful your device is.
The most common processors are single-core, but the number of more powerful smartphones with 2 or even 4-core processors has been steadily growing over time. If you plan to watch high-definition video and perform work in several applications at the same time, then it is worth considering models with two or more cores. With a clock frequency of 800 MHz, and possibly even higher than 1 GHz.
Also depending on your needs is selected. In smartphones, it is usually higher, respectively, the quality of the photo taken by the device increases. It should be noted that the vast majority of smartphones at the moment cannot replace a digital camera.
