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). Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology

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. 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. Focal length and 35 mm equivalent Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. 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.You should manually readjust the focus of pictures often, since there are some slight problems here, and also the screen overall is too dark. The speaker is rated below the level of this price class, which is low anyways, and the graphics card is weak and hardly future proof. UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology. Information about the manufacturer and model of the image sensor used by this camera of the device. 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. Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation.

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. 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. 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. 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. There are several pre-installed apps that support the management of the smartphone and provide extended functions. LG subsidizes the affordable price by installing a few apps, like Facebook, for example. However, since these are just three apps, we can live with that.

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. Even the K8’s GPU performance was good, as graphics tends to be an area where MediaTek chips have struggled in the past compared to their Qualcomm-based counterparts. In GFX Bench GL’s offscreen Manhattan 3.0 test, for example, the LG K8 scores a very reasonable 188 frames (around 3.0fps), putting it ahead of the 3rd Gen Moto G which only produced 103 frames (or 1.7fps). Battery The batteries of mobile devices differ in capacity and technology. They provide the electrical charge needed for the functioning of the devices. Capacity 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. 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.

talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 2G cellular network.

Emissions

As with the LG K10 (2017)before, with the LG K8 (2017) the Korean manufacturer also delivers quite a high-quality budget smartphone, which offers features not always found in this price range. First, there is the decent equipment supporting NFC and the modern bluetooth standard. However, for the highlight of a fingerprint sensor, you look in vain. Instead, there is a good call sound and cameras that are very good for this price class. Precise input devices and a removable battery with a decent runtime also belong to the upsides of the LG K8 (2017), and the casing appears relatively high-quality as well. 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.

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.
