6.height

148.9mm

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
The Ingress Protection (IP) rating classifies the degree of protection against dust and water. Higher ratings are better. For example, a device rated IP68 can resist immersion into water for a certain time, specified by the manufacturer.
8.volume

89.94cm³

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.
Text messaging is much faster due to a hardware keyboard.

Display

Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
2.resolution

1080 x 2340px

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
The bigger the screen size is, the better the user experience.
Damage-resistant glass (such as Corning Gorilla Glass or Asahi Dragontrail Glass) is thin, lightweight, and can withstand high levels of force.
OLED (Organic Light-Emitting Diode) displays are formed of organic materials that emit light. They have higher contrast ratios and wider viewing angles compared to LCDs. AMOLED and POLED are types of OLED displays.
Gorilla Glass is one of the most popular brands of chemically strengthened glass, manufactured by Corning. Several versions have been developed, the newer ones being more durable and providing better damage resistance.
You can operate the device easily, by pressing the screen with your fingers.
The frequency at which the screen is refreshed. Higher frequency results in less flickering (less noise) and more natural movement representation in action-intense scenes.
9.Always-On Display

The user can see information such as date, time, and notifications even when the screen is off. The functionality can be enabled or disabled.

Performance

Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.
2.CPU speed

2 x 2.86GHz & 2 x 2.36GHz & 4 x 1.95GHz (Huawei Kirin 990 5G)

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.
The internal storage refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device.
The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
It can support faster memory, which will give quicker system performance.
A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.
Using big.LITTLE technology, a chip can switch between two sets of processor cores to maximize performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximize battery life.

Cameras

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
The number of megapixels determines the resolution of the images captured with the front camera. A higher megapixel count means that the front camera is capable of capturing more details, an essential factor for taking high-resolution selfies.
Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.
The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
5.wide aperture (main camera)

f/1.9 & f/2.2 & f/2.4

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.
7.has a BSI sensor
Huawei P40
A BSI (backside illuminated) sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality.
When recording movies they stay focussed and sharp.
Phase-detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.

Audio

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
With a standard mini jack socket, you can use the device with most headphones.
