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. Front camera Modern smartphones have one or more front cameras and their positioning has led to various design concepts – pop-up camera, rotating camera, notch, punch hole, under-display camera, etc. Aperture Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation. CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications.

Information about additional software and hardware features of the front camera which improve its overall performance. One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions.

Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor.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. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology Information about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC 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.

f/2.2, като може да записва видео в резолюция до 1080p при 30 кадъра в секунда. Има и система за автофокус със засичане на фазата. В софтуерно отношение е използвана Android 10 с MIUI 12. Сред останалите характеристики на Redmi 9A са Wi-Fi n, Bluetooth 5.0, Micro USB порт и жак за слушалки. Конструкцията му е пластмасова и с размери 164.9 x 77.1 x 9 мм и тегло 196 гр. Телефонът се предлага в сив, син и зелен цвят. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. The SAR body rating shows the maximum level of exposure to electromagnetic radiation when the device is positioned against the body at the hip. The highest SAR value of mobile devices allowed in the US is set to 1.6 W/kg per 1 g of tissue. It is specified by the FCC and the CTIA follows whether the mobile devices comply with this standard. In India, the highest body SAR level is limited to 1.6 W/kg per 1 g of tissue. The Telecom Engineering Centre (TEC) or an internationally accredited lab measures and certifies the mobile devices comply with this standard. W-CDMA (Wideband Code Division Multiple Access) is an air interface used by 3G mobile networks. It is one of the three different UMTS interfaces together with the TD-SCDMA and the TD-CDMA. The standard provides faster data transfer speeds and allows more users to connect to the network simultaneously.

The SAR head rating shows the highest level of exposure to electromagnetic radiation measured when the device is held next to the ear in a talk position. In Europe, the SAR limit for hand-held mobile devices is set to 2 W/kg per 10 g of tissue. This standard is specified by the CENELEC, complies with the IEC standards and follows the ICNIRP Guidelines 1998. One of the main characteristics of the display is its type/technology, on which depends its performance.
