Product Information

The handsets are both 6.5in devices featuring a V-shaped notch for said selfie camera. While both phones are near enough the same physical size, the two handsets also differ in terms of their battery capacity: 3,000mAh on the regular phone and 4,000mAh on the Plus model. Both batteries, unusually, are user-replaceable, which is a design decision that’s gone out of fashion over the course of the last decade and something we’ve certainly missed.

Information about the manufacturer and model of the image sensor used by this camera of the device. Nokia C21 Plus mobile was launched on 27th February 2022. The phone comes with a 6.52-inch touchscreen display offering a resolution of 720x1600 pixels and an aspect ratio of 20:9. Nokia C21 Plus is powered by an octa-core Unisoc SC9863A processor. It comes with 2GB, 3GB, 4GB of RAM. The Nokia C21 Plus runs Android 11 (Go edition) and is powered by a 4000mAh battery.Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology Information about additional software and hardware features of the rear camera which improve its overall performance. 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. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. 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.

Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSMThe Nokia C21 Plus runs Android 11 Go Edition, which is a tailored version of Google’s mobile OS specifically designed for low-end devices. What this means is that the phone launches with tweaked ‘Go’ versions of Google’s applications, such as Chrome, Maps and Gmail. The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements. 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 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.
