Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. 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. While I know the benchmarks I logged aren’t pulling up any trees, the key thing is that Nokia has also realised this. As a result, it has skipped putting the full-fat version of Android on the C21 Plus and opted for the much more lightweight (and less bloated) Android 11 Go. One of the main characteristics of the display is its type/technology, on which depends its performance. 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.

Connectivity options on the Nokia C21 Plus include Wi-Fi 802.11 b/g/n, GPS, Bluetooth v4.20, USB OTG, Micro-USB, 3G, and 4G (with support for Band 40 used by some LTE networks in India). Sensors on the phone include accelerometer, ambient light sensor, proximity sensor, and fingerprint sensor.Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation.

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. 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 Nokia C21 Plus has a large 6.52in 720p IPS display and a dual-camera array. A Unisoc SC9863A processor runs the show, alongside 2GB of RAM, 32GB of expandable storage and a 4,000mAh battery. It uses a specially tailored version of Android for low-power devices, called Android 11 Go, with Nokia promising up to two years of core Android upgrades as well. Nokia C21 Plus review: Price and competition Finally, video is captured at 1080p and 30fps, up from the 720p limit on the Nokia 1.4. Footage looks good for the most part but there’s no image stabilisation so you’ll have to be careful to hold your phone still when recording. Nokia C21 Plus review: VerdictInformation about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU. There’s an okay amount of detail to captured images and the colour balance is nice and neutral but it’s far from perfect. Depending on the light, photographs can look soft and in bright conditions, it had a tendency to overexpose images. There was a fair amount of lag between pressing the shutter button and the camera actually capturing the image, too. 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. Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications.

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. 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. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSMInformation 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. Graphics rendering is also much improved, although the picture here is still rather bleak. An average on-screen frame rate of 16fps in the GFXBench Manhattan 3 gaming test is over three times faster than the Nokia 1.4’s result but there’s still a lot of room for improvement. 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. The 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.
