Display

1.pixel density

402ppi

515ppi

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 2400px

1440 x 3200px

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

6.55"

6.81"

The bigger the screen size is, the better the user experience.

Xiaomi Mi 11
Damage-resistant glass (such as Corning Gorilla Glass or Asahi Dragontrail Glass) is thin, lightweight, and can withstand high levels of force.
5.has an IPS screen
OnePlus 9
Xiaomi Mi 11
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.
6.Has an OLED or AMOLED display
OnePlus 9
Xiaomi Mi 11
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.
7.has a touch screen
OnePlus 9
Xiaomi Mi 11
You can operate the device easily, by pressing the screen with your fingers.
8.refresh rate

120Hz

120Hz

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.has an HDR10-enabled display
OnePlus 9
Xiaomi Mi 11
The display supports HDR10, which is an HDR (high dynamic range) video technology. Compared to standard dynamic range (SDR) video, HDR10 video has greater contrast and color depth, resulting in more realistic images.

Performance

1.RAM

12GB

12GB

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

1 x 2.84GHz & 3 x 2.42GHz & 4 x 1.8GHz (Qualcomm Snapdragon 888)

1 x 2.84GHz & 3 x 2.42GHz & 4 x 1.8GHz (Qualcomm Snapdragon 888)

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
OnePlus 9
Xiaomi Mi 11
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.
With integrated graphics you don’t need to buy a separate graphics card.

Cameras

1.megapixels (main camera)

50MP & 48MP & 2MP

108MP & 13MP & 5MP

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.
4.video recording (main camera)

4320 x 30fps

4320 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.wide aperture (main camera)

f/2.2 & f/1.8 & f/2.4

f/1.9 & f/2.4 & 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.
6.Has a dual-tone LED flash
OnePlus 9
Xiaomi Mi 11
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
OnePlus 9
Xiaomi Mi 11
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

1.has stereo speakers
OnePlus 9
Xiaomi Mi 11
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.has a socket for a 3.5 mm audio jack
OnePlus 9
Xiaomi Mi 11
With a standard mini jack socket, you can use the device with most headphones.
3.Has a radio
OnePlus 9
Xiaomi Mi 11
A built-in FM radio tuner allows you to listen to most of the live-broadcasted FM radio stations without using the internet.
More microphones result in better sound quality and enable the device to filter out background noise.

4.has a removable battery
OnePlus 9
Xiaomi Mi 11
The battery is removable and can be replaced by the user if broken.
The ultra power-saving mode, also called low power mode, is an effective way to extend the battery life of the device. Usually, it involves limiting screen brightness and contrast, disabling location services, restricting connectivity, and turning off nonessential apps.
