Product Information

The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM. The capacity of a battery shows the maximum charge, which it can store, measured in mili-Ampere hours. 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.

Battery The batteries of mobile devices differ in capacity and technology. They provide the electrical charge needed for the functioning of the devices. Capacity 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. Carrying only one phone, you will enjoy either fast local networks or the freedom of two roles cause the phone support tow SIM cards connect to two networks simultaneously. Meanwhile, two SIM cards and one TF card could be used at the same time cause Ulefone Note 7 equips three card slots.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.

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. Sensor type 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. 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. 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. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. WidthThe 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). 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. 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.
