How to pick up the phone for the parameters: characteristics and variations in form factor

How to choose the right phone or brief digression on their types

During the existence of mobile phones, they have gone through more than one revolution. The changes affected not only the technical parameters, but also appearance. Each manufacturer in all that time trying to win the market and the consumer's attention, attracting the original form or the eye-catching design. All these types and varieties of devices have been invented since the invention of cell phones.

Monoblocks

The most popular type of phone, which continues to be used confidently to the present. It comprises a single body devoid of moving parts.

To choose the right mobile phone for performance, you should know what kinds of candy bars existed and exist today:

1. Classic, equipped with a numeric keypad. In appearance, these devices look like any normal phone and lack of moving parts. Outstanding representatives of such recent line can be considered an updated Nokia 3310 (cost - 3200 rubles).
   

   BlackBerry traditionally manufactured devices with a full keyboard

2. Smartphones, equipped with a QWERTY-keyboard. This device, including a full set of keys to make it easy to carry out a set text. The most famous brand, producing such models is the BlackBerry. Q10 model of brand catalog can be bought at the price of 12 000 rubles.
3. Models with a folding QWERTY-keyboard. A distinguishing feature of such apparatus is the presence of a pair of covers drop under the screen plane are represented in the form of an unfolded full keyboard. The brightest representative of this class was the Nokia 6800, a year which was the 2003 release.

4. Phones with a flip. Flip - a small hinged lid, which covers the keypad and earpiece. The advantage of such forms is the ability to save the small size of the apparatus, which unfolded as it becomes convenient for the full conversation. The displacement type in the user ranking comes after the appearance of "clamshell". The most prominent representatives of the class is the Samsung N400 and Sony Ericsson Z
5. Monoblock is equipped with a rotary bottom part. This solution has been deployed by Nokia just two models, who could not win the sympathy of buyers due to excessive frills and unusual. working principle is that the lower part of the phone can be rotated 180 ° for quick launch camera. Models who have had this type of form factor, steel Nokia 3250 and Nokia

6. touchscreen smartphone. Habitual each of the phone, which is a candy bar, most of which - a display with a touch input. If we compare what phone is better, the majority of respondents when answering this question will say that it is this type, because it has become familiar and understandable to everyone.

"Folding"

The next form factor cell phones, which is a device consisting of two parts. The upper half - a display and a speaker, positioned on the lower segment of the keyboard and a microphone. Typically, such models are additionally equipped with an external screen having a smaller number of colors and low resolution and are necessary to display alerts or time display.

slider

A variation of a foldable phone, where the opening of the machine and its translation into operation carried out by the parallel sliding the two halves of the housing established in the sled. In addition, it was coined by a slightly modified format, known as a side-slider. In this case, the shift is carried out, not up on the wide side that provides access to a full QWERTY-keyboard.

In stores you can still find the sliders. Basically it is a model of Chinese brands "second tier". For example, Jinga Simple SL100, which is sold at a price - 2100 rubles. When the decision to buy such a device do not look for quality. This extra-option.

Additionally, there may be mentioned about such formats as kick slider smartphone or the hinge fastening moving parts, psevdoraskladushki, lids which contain only the speaker and rotators machines with rotary mechanism, built on the principle of folding knife. All these models are gone and are rarities, which failed to win the market.

How to choose a smartphone on the characteristics and parameters

Entry on the existing form factor is more of a background character as the selection of the phone on the characteristics of this criterion is not taken into account. The reason for that is not the reluctance of the end user and the marketing conditions that exist in the market, which suggest the presence of a single format, recognized by most convenient. If there are some unusual models, they are isolated.

Selection of the characteristics of a smartphone made taking into account the following parameters:

• materials from which the housing is made;
• operating system;
• CPU;
• type of memory;
• matrix;
• a camera;
• Battery capacity.

Phone Select by parameters - body materials

Many people put this criterion is almost in last place. But in fact this decision is wrong. Modern smartphone, especially mid-range or premium offer elegant design, suggesting the use of metal and glass.

Each material has its advantages and disadvantages:

• metal It has a high strength, all metal but the phone is not capable to maintain a normal level of the signal;
• plastic reliable, low cost, but these smart phones look quite cheap;
• glass - it is a very fragile material, especially in the low-cost models.

Some manufacturers produce a limited series of class "luxury", where the manufacture of the material, or rather the outer coating is a genuine leather or wood. All this affects the significant increase in cost.

Processor - an important parameter for the selection of the smartphone

One of the main selection criteria at the decision to buy a new phone is its technical stuffing, the center of which is the processor. To date, more than 70% of the market of mobile processors is represented by two major vendors - Qualcomm and MediaTek. These companies throughout the time are competing.

NOTE! (Click to see)

Products of the first brand may vary high clock speeds or rates of efficiency, but in reality they lose processors by Qualcomm at the expense of the weaker video accelerators. That is why the choice of inexpensive, but a good phone to perform daily tasks, you can safely choose MediaTek. If your smartphone is purchased for the games, then it is better to look at the products under the brand name Snapdragon.

operating system

the most widely used among Android and iOS mobile operating systems. The first version of the OS is totally free and is available on the principle of open source or open source. The second is only installed on the Apple device.

Android - a system that requires users to freedom of action, change the appearance of design, file system modifications, the presence of a large number of applications.

iOS - the choice of buyers who want to acquire the smartphone easy to use, getting regular updates, a strong technical support. Not so long ago the market was present more than one operating system - Windows Mobile, which is installed on their phones, Nokia. But this software during its existence was not perfect, resulting in the loss of popularity.

How to pick up the phone on the screen size

Another important part when choosing a smartphone display, because it determines the quality and comfort of use of color reproduction. When screen the user needs to decide on its size. Display size is expressed in inches. The optimal rate for modern devices ranges from 5 to 5.5 inches.

The second indicator to which you want to look for when considering a better display is its resolution. Most common are two indicators - HD (1280 × 720 dots per inch) and Full HD (1920 × 720 dots). The screen resolution should depend on the size of the diagonal. For devices having a display 5 inches should be selected HD or higher, because otherwise it will be apparent individual pixels on the screen, and decrease sharpness of images.

All permits, reaching higher Full HD (2K, 4K), designed primarily for large TVs. On the screen of the smartphone the difference between the naked eye can notice one person in 10. Another important criterion to look at when you want to choose a cell phone, a type of matrix. Modern manufacturers produce three varieties:

1. TNT. The cheapest option, which is used mostly in the cheapest models. Its resolution is not even full HD. Image contrast is obtained with the disadvantage of substantially inverted when changing the viewing angle.
2. IPS. Matrix, recognized "gold standard" in the manufacture of screens. These displays have good viewing angles, high brightness and contrast settings, provide the most natural color reproduction.
3. AMOLED. Brand invention Samsung, which uses this type in their products. A distinctive feature is the intense black color, high contrast, good energy efficiency. Some users have complained that in the matrix of color AMOLED overly saturated, resulting in an unnatural picture.

Pick up the phone memory performance

Every year the power of smartphones, which requires not only a change of processors, but also improve memory. Inside mobile devices, there are two types:

• RAM, which is used to save the currently running applications and their communication with the central processor;
• ROM or internal, which is similar to a computer hard drive and used to store information.

The minimum amount of RAM that is required for today's smartphone - 2 GB, otherwise the user will encounter a great braking operation. When this criterion is the rule: more - the better. The market is already possible to find machines with up to 8 GB of "RAM". Of this amount will be enough for a couple of years to a smartphone run faster and without glitches.

Permanent memory is increasingly used to host user-generated content, such as photos. Therefore, if you plan to use your smartphone as a replacement for a conventional camera, you should pay for this option special attention or consideration phone purchase option with support for external memory cards of maximum capacity.

How to choose a phone built-in camera in the parameters

Cameras "Soap" a thing of the distant past. Now everyone captures interesting moments to your smartphone. Therefore, the camera is an important criterion for selection. Result obtain quality images will depend on a number of parameters:

1. photosensitivityOr the aperture of the optical module. Expressed as f / n, where n - is the size of the aperture. The maximum value of this fraction is achieved with minimal divider. Therefore, the best images will be obtained on the cameras, where n is minimal. By itself, this parameter indicates the size of the aperture of the pupil, and affects the amount of trapped light.
2. autofocus. There contrast, phase, or combined laser focusing system. Most quality focuses on the subject of shooting laser, but the use of this type of impact on the final cost of the smartphone. The purpose of the option is to get a clear picture in minimum time.
   

   When questions about the quality of images available, you can see the test pictures comparing the work of the Chambers of the most popular smartphones

3. optical stabilization. Indicator, which is more important when shooting video. It is a system that ensures smooth image in the presence of a slight shake (eg operator's hand).
4. The dynamic range of the sensor. There quality depends on the latitude. The higher it is, the less likely to get overexposed frame or lose information on a darkened or too bright areas of the image.
5. hardware component. No less important is the algorithm of the finished photo processing, which is used in the smartphone. Some manufacturers algorithm is adapted so that when the level of illumination excessive smoothing occurs to get rid of noise, which leads to loss of image contrast and field. Check the quality of this factor can only empirically.

A comparison of the characteristics of the battery capacity phones

Since the touch screen consumes a lot of energy, then the choice of battery capacity is important when buying, so as not to charge the device several times a day. Modern technologies allow to create a battery to 6000 mAh capacity. The median, which can be guided, - 3200-3500 mAh. That's enough to normal mode (talk, browsing the Internet and email, casual toy) phone lasted until the evening. When choosing the parameters of the smartphone and the price you should pay attention to the support of fast charging. This will ensure the completion of the battery to 100% of a half hours on the average.

Which phone is best to choose a brand

Many are wondering how to choose a good and inexpensive smartphone simultaneously. There is no single recipe. Some people believe that the products of famous brands (Samsung, LG, Nokia, Sony) quality, even in low-end segment. In reality, the Chinese A-brands (Xiaomi, Meizu, Huawei) offer cheaper models, which are not inferior in performance flagship of the leading manufacturers. We should also mention Apple's, production of which has never been cheap, and most of image, so buy iPhone is largely dictated by the fashion than high-performance machine.

And what do you think is the best smartphone? Maybe there are devices that are no longer manufactured, but you work well? Share them with others. In the meantime, look useful videos on the subject.
