Today, the cell phone has become an indispensable device for almost every person. There are a huge variety of different models of mobile phones on the modern market, from elementary devices (for example, for your grandmother) to models with an infinite number of possibilities. The choice of a mobile phone must be approached with maximum attention, because not every person can afford to frequently change cell phones. So, in order to make the right purchase, you need to know the following characteristics.
Instructions
Step 1
Form Factor
At present, the most popular designs of cell phones are as follows: standard candy bar, clamshell and slider. • candy bar - the most common type of phones, it has one screen and a keyboard. If you choose such a model, then you should not chase the minimum size of the phone, since you will have to constantly hold the phone to your ear to hear the interlocutor, or to your mouth to answer him. Also, such mobile devices do not have screen protection, so it is advisable to carry the phone in a case.
• All candy bar problems are solved in clamshell phones. In such models, the microphone and speaker are placed at an optimal distance, so you do not have to be torn between the desire to hear or answer the interlocutor. For maximum convenience, choose a "clamshell", which has an external screen, on which you can see the caller's number. The only drawback of such models is that the design of the phone is designed only for a certain number of openings and closings.
• A slider is a device in which the screen and keyboard are placed on different parts. Only the keyboard is protected in the slider, so these phones should also be stored in a case.
Step 2
Display.
The quality of the image that you see on a phone screen depends on several characteristics: the type, size and resolution of the display. The main types of phone displays are UFB, STN, TFT and OLED screens. The first two are used on low-cost models, while OLED and TFT screens can be found on upper-mid-range phones. The screen size should be selected according to your needs. If you are going to watch videos or pictures often, then it is worth buying a phone with a large screen.
Step 3
Battery type and capacity.
One of the most important factors when choosing a phone is the duration of its operation, it depends on the type and capacity of the battery. There are now two types of batteries used in mobile phones: lithium-ion and lithium-polymer. Phones equipped with lithium-ion batteries do not need to be charged until they are completely discharged. But lithium polymer batteries are energy-intensive and long-lasting.
As a standard for mobile phones with the usual set of functions, batteries with a capacity of 600-800 mAh are used, and for communicators - 1000-1500 mAh.
Step 4
Memory.
If you need a phone with advanced multimedia functions, then you should choose a model with the ability to connect external memory cards. Otherwise, you may face the fact that, having an excellent mp3 player, you will not be able to store even a dozen different songs.
