We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.
4.width

70.1mm

77.01mm

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

142.1mm

163.32mm

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
6.has a physical QWERTY keyboard
Samsung Galaxy S6 Edge
Xiaomi Redmi 9
Text messaging is much faster due to a hardware keyboard.

Display

1.pixel density

577ppi

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

1440 x 2560px

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.
3.screen size

Performance

1.RAM

3GB

4GB

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

8 x 2.1GHz

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

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.
3.has an external memory slot
Samsung Galaxy S6 Edge
Xiaomi Redmi 9
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.
5.Has integrated LTE
Samsung Galaxy S6 Edge (Samsung Exynos 7420)
Xiaomi Redmi 9 (MediaTek Helio G80)
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.
8.Supports 64-bit
Samsung Galaxy S6 Edge (Samsung Exynos 7420)
Xiaomi Redmi 9 (MediaTek Helio G80)
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.
9.Uses big.LITTLE technology
Samsung Galaxy S6 Edge (Samsung Exynos 7420)
Xiaomi Redmi 9 (MediaTek Helio G80)
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

1.megapixels (main camera)

16MP

13MP & 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.
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
Samsung Galaxy S6 Edge
Xiaomi Redmi 9
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.
4.video recording (main camera)

2160 x 30fps

1080 x 30fps

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.Has a dual-tone LED flash
Samsung Galaxy S6 Edge
Xiaomi Redmi 9
A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.
6.has a BSI sensor
Samsung Galaxy S6 Edge
Xiaomi Redmi 9
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.
7.has continuous autofocus when recording movies
Samsung Galaxy S6 Edge
Xiaomi Redmi 9
When recording movies they stay focussed and sharp.
8.Has phase-detection autofocus for photos
Samsung Galaxy S6 Edge
Xiaomi Redmi 9
