Information about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen. The battery type is determined by its structure and more specifically, by the chemicals used in it. There are different battery types and some of the most commonly used in mobile devices are the lithium-ion (Li-Ion) and the lithium-ion polymer battery (Li-Polymer). talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 2G cellular network.

A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.

Models

Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.

stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 3G mobile network. Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width

The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 2G cellular network.

Information about the height, i.e. the vertical side of the device when it is used in its standard orientation.Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc.
