4.height

163.32mm

165.8mm

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
5.width

77.01mm

76.7mm

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
6.volume

114.45cm³

111.91cm³

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.

Display

1.pixel density

395ppi

395ppi

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

1080 x 2400px

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.

5.LCD display with 3 subpixels per pixels
Xiaomi Redmi 9
Xiaomi Redmi Note 9S
The device has an LCD display with 3 subpixels per pixel, resulting in sharp and crisp images. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
6.has an IPS screen
Xiaomi Redmi 9
Xiaomi Redmi Note 9S
IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. PLS (Plane-to-Line Switching) is a type of IPS screen developed by Samsung, with increased brightness and lower production costs.

Performance

1.CPU speed

2 x 2GHz & 6 x 1.8GHz (MediaTek Helio G80)

2 x 2.3GHz & 6 x 1.8GHz (Qualcomm Snapdragon 720G)

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.
2.RAM

4GB

6GB

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.
3.has an external memory slot
Xiaomi Redmi 9
Xiaomi Redmi Note 9S
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.
4.internal storage

64GB

128GB

The internal storage, also called read-only memory (ROM), 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.
5.Has integrated LTE
Xiaomi Redmi 9 (MediaTek Helio G80)
Xiaomi Redmi Note 9S (Qualcomm Snapdragon 720G)
The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.
6.semiconductor size
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.

Cameras

1.megapixels (main camera)

13MP & 8MP & 5MP & 2MP

48MP & 8MP & 5MP & 2MP

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.
2.megapixels (front camera)

8MP

16MP

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.
3.has built-in optical image stabilization
