Product Information

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. Battery The batteries of mobile devices differ in capacity and technology. They provide the electrical charge needed for the functioning of the devices. Capacity Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. 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).

Information about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well. 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.Bluetooth, EDGE, FDD-LTE, GPRS, GSM, HSDPA, HSPA, HSPA+, HSUPA, LTE, LTE-A, SMS, UMTS, VoLTE, WCDMA, WiFi 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. The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute. Information about the electric current (amperes) and voltage (volts) the charger outputs. The higher power output allows faster charging.

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 capacity of a battery shows the maximum charge, which it can store, measured in mili-Ampere hours. One of the main characteristics of the display is its type/technology, on which depends its performance.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. 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 process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.

talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 2G cellular network. Information about additional software and hardware features of the rear camera which improve its overall performance.

RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.
