Width information - refers to the horizontal side of the device in its standard orientation during use.

Height information - refers to the vertical side of the device in its standard orientation during use.

Information about the thickness of the device in different units.

Information about the weight of the device in different units of measurement.

The approximate volume of the device, based on the dimensions provided by the manufacturer. Refers to devices with a rectangular parallelepiped shape.

Information about the colors in which this unit is offered for sale.

Materials used to make the device body.

A system on a chip (SoC) integrates various hardware components such as a processor, graphics processor, memory, peripherals, interfaces, etc., as well as the software required for their operation.

Information about the technological process by which the chip is manufactured. The value in nanometers is half the distance between the elements in the processor.

The main function of the processor (CPU) of a mobile device is to interpret and execute instructions contained in software applications.

The capacity (bits) of the processor is determined by the size (in bits) of registers, address buses and buses for data. 64-bit processors offer better performance than 32-bit processors, which, in turn, are more powerful than 16-bit processors.

Instructions are commands with which the software sets / controls the processor. Information about the instruction set (ISA) that the processor can execute.

The cache memory is used by the processor to reduce the time it takes to access more frequently used data and instructions. L1 (Level 1) cache is small and is much faster than both system memory and other levels of cache. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2.

L2 (level 2) cache is slower than L1, but instead has a larger capacity, allowing more data to be cached. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in L3 cache memory (if available) or in RAM memory.

The processor core executes program instructions. There are processors with one, two or more cores. Having more cores increases performance by allowing multiple instructions to execute in parallel.

The clock speed of a processor describes its speed in cycles per second. It is measured in megahertz (MHz) or gigahertz (GHz).

A graphics processing unit (GPU) handles computation for a variety of 2D / 3D graphics applications. In mobile devices, it is most commonly used by games, consumer interfaces, video applications, and more.

Like a processor, a GPU is made up of several working parts called cores. They handle the graphical computing of various applications.

Speed \u200b\u200bis the clock speed of the GPU and is measured in megahertz (MHz) or gigahertz (GHz).

Random access memory (RAM) is used by the operating system and all installed applications. The data that is saved in RAM is lost after the device is turned off or restarted.

Information about the type of random access memory (RAM) used by the device.

The frequency of the RAM determines its speed of operation, more specifically, the speed of reading / writing data.

One of the main characteristics of the screen is the technology by which it is made and on which the image quality of information directly depends.

On mobile devices, screen size is expressed in terms of the length of its diagonal, measured in inches.

Approximate screen width

Approximate screen height

The aspect ratio of the long side of the screen to its short side

Screen resolution indicates the number of pixels horizontally and vertically on the screen. Higher resolution means sharper image detail.

Information about the number of pixels per centimeter or inch of the screen. Higher density allows information to be shown on the screen in clearer detail.

Screen color depth reflects the total number of bits used for color components in one pixel. Information about the maximum number of colors the screen can display.

The approximate percentage of the display area on the front of the device.

Information about other functions and features of the screen.

The most common types of flashes in mobile devices are LED and Xenon flashes. LED flashes give softer light and, unlike brighter xenon ones, are also used for video shooting.

One of the main characteristics of mobile device cameras is their resolution, which shows the number of pixels horizontally and vertically in an image.

Information about the maximum supported resolution for video recording by the device.

Information about other software and hardware features associated with the main camera to improve its functionality.

The capacity of a battery indicates the maximum charge it can store, measured in milliampere-hours.

The type of battery is determined by its structure and, more precisely, by the chemicals used. There are different types of batteries, with the most common mobile devices using lithium-ion and lithium-ion polymer batteries.

2G talk time is the period of time during which the battery charge is completely discharged during continuous 2G talk.

Standby time in 2G is the period of time during which the battery charge is completely discharged when the device is in stand-by mode and connected to a 2G network.

Talk time in 3G is the period of time during which the battery charge is completely discharged during a continuous conversation on a 3G network.

3G standby time is the period of time during which the battery is fully discharged when the device is in stand-by mode and connected to a 3G network.

Information about some additional characteristics of the device battery.
