Dynamic Range and Color Profile
The standard four key video from the rear camera of the Redmi K20 Pro, OnePlus 7 and Xiaomi Mi 9 all display a similar dynamic range and color profile. The footage appears slightly oversaturated with an emphasis on red hues, yet the results remain clean and consistent. Bearing in mind the price difference between the three devices, the K20 Pro can be purchased for approximately $360, the OnePlus 7 for $530 and the Mi 9 for $470.
Zoom Quality
Though both the Redmi K20 Pro and Mi 9 have 2x telephoto lenses, neither uses them when recording video. When zooming in 2x, the quality of the footage is comparable, however, when zooming in 5x, the OnePlus 7’s footage appears slightly clearer. This is due to its more aggressive HDR rather than its ability to capture more detail.
Ultra-Wide Cameras
The K20 Pro and Mi 9 both have ultra-wide cameras, which make a noticeable difference when recording video. The OnePlus 7, however, does not have an ultra-wide camera, yet still manages to capture more detail and more accurate colors than the other two devices.
Redmi K20 Pro vs OnePlus 7 vs Xiaomi Mi 9 Camera Test Comparison
The Redmi K20 Pro, OnePlus 7, and Xiaomi Mi 9 are three of the most popular smartphones on the market, and each has its own strengths and weaknesses when it comes to camera performance. In this comparison, we’ll take a look at how each phone fares in terms of video and photo quality, as well as stabilization and low-light performance.
Video Quality
When it comes to video quality, the Redmi K20 Pro and OnePlus 7 both have electronic stabilization, which helps to reduce jitter when walking. However, the OnePlus 7 has the edge here, thanks to its sharper footage and ability to record slow motion video at 240 frames per second. The Xiaomi Mi 9 can only record slow motion video in short bursts of 960 frames per second.
Photo Quality
When it comes to photos, all three phones have a dedicated night mode, but the OnePlus 7 comes out on top, followed by the Redmi K20 Pro and then the Xiaomi Mi 9. The OnePlus 7 offers sharper edges and more detail, while the Mi 9’s photos suffer in low light.
Stabilization
The Redmi K20 Pro and OnePlus 7 both offer electronic stabilization, which helps to reduce jitter when walking. However, the OnePlus 7 has the edge here, thanks to its sharper footage and ability to record slow motion video at 240 frames per second. The Xiaomi Mi 9 can only record slow motion video in short bursts of 960 frames per second.
Low-Light Performance
When it comes to low-light performance, all three phones suffer, but the Xiaomi Mi 9 is the furthest behind. Edges have lost a lot more sharpness than on the other two phones, and this trend continues into photos. The OnePlus 7 offers the best low-light performance, followed by the Redmi K20 Pro and then the Xiaomi Mi 9.
Overall, the OnePlus 7 offers the best camera performance of the three phones, with sharp video and photo quality, good stabilization, and excellent low-light performance. The Redmi K20 Pro is a close second, while the Xiaomi Mi 9 lags behind in terms of video and photo quality, stabilization, and low-light performance.
Noise Reduction
The Xiaomi phone utilizes a very aggressive noise reduction technique, resulting in less grain than the K 20. This can be seen when comparing the texture of the bench behind me in this shot, where a massive difference is evident between the Redmi and the Xiaomi.
Night Mode
The telephoto lenses of the Redmi and Xiaomi can be used in night mode, while the OnePlus 7 requires the user to crop into the photo afterwards. This means that if one wishes to zoom in, a lot of fidelity will be lost.
Ultra Low Light
In ultra low light, the Xiaomi Mi 9 produces a messy image, while the OnePlus 7 tends to make the image look too warm. This issue is not restricted to just the OnePlus 7.
Flash
Without external lighting, the OnePlus 7 does a better job of keeping the image true to life when using the flash.
Front Camera
The same trend is seen when using the front cameras, with the K 20 Pro having a bit more grain than its Xiaomi counterpart. When it comes to video from the front camera, the OnePlus 7 crops into the sensor, making the footage look much closer to the user. Additionally, the OnePlus 7 captures more detail than the other two phones.
Rear Cameras
When looking at photos taken with the rear cameras, it is possible to distinguish the Mister Whos The Boss logo on my shirt.
Redmi K20 Pro
The Redmi K20 Pro is a great choice for those looking to take photos in good lighting. Its ultra-wide camera makes a game-changing difference, allowing users to capture more of the scene. In addition, the K20 Pro also allows users to take panorama shots on the front camera, giving them a wider field of view. However, the K20 Pro does not have the best selfie camera, as it can make users look a little bit red in some lighting conditions.
OnePlus 7
The OnePlus 7 has the best selfie camera of the three phones, creating the most bokeh. However, when recording video, the OnePlus 7 crops into the scene, making it less than ideal for vloggers. Additionally, the OnePlus 7 does not have an ultra-wide camera, meaning users cannot capture as much of the scene as they can with the Redmi K20 Pro.
Xiaomi Mi 9
The Xiaomi Mi 9 has great edge detection, even in difficult scenarios. It produces well-balanced colors, almost reminiscent of the iPhone 10s footage. However, the Mi 9 does not have an ultra-wide camera like the Redmi K20 Pro, and it does not have the best selfie camera like the OnePlus 7.
1.6 aperture, you can get some really nice shots.
Redmi K20 Pro vs OnePlus 7 vs Xiaomi Mi 9 Camera Test Comparison
The Redmi K20 Pro, OnePlus 7 and Xiaomi Mi 9 all offer a range of camera features, but how do they compare when put to the test? When it comes to night shots, the K20 Pro captures more than the OnePlus 7, and even more than the Xiaomi Mi 9. The Mi 9 can capture a 117-degree field of view, while the K20 Pro can capture a closer to 105-degree field of view, making for more dramatic shots.
The OnePlus 7 feels the pain when it comes to zooming in, as it lacks a telephoto camera. If you want to take a 10x zoom shot, it is far behind the other two phones. The Mi 9 takes it marginally, with the K20 Pro’s shots being slightly over-sharpened.
Things get interesting when it comes to portrait mode. The K20 Pro and Mi 9 both use their telephoto cameras for this, resulting in less face distortion than the OnePlus 7. With the OnePlus 7, you have to get close to the subject’s face to take a portrait shot, which can make their face look too rounded. The OnePlus 7 does have the closest focusing distance, however, and combined with its wide f/1.6 aperture, you can get some nice shots.
In terms of video, all three phones can record in 4K at 30fps, but the K20 Pro and Mi 9 can record in 4K at 60fps. The Mi 9 also has a 960fps slow-motion mode, while the K20 Pro has a 720fps slow-motion mode.
Overall, the K20 Pro and Mi 9 offer the best camera features, with the OnePlus 7 lagging behind. The K20 Pro and Mi 9 have the advantage of telephoto cameras for portrait mode, as well as higher frame rates for recording video.

Aperture
The Redmi K20 Pro, OnePlus 7, and Xiaomi Mi 9 all feature a 1.7 aperture, which allows for more background blur in non-portrait shots. This is an important feature to consider when comparing the three phones.
Detail
When all three phones are set to 12 megapixels, the difference in detail is minimal. Cropping in 20 times reveals little difference between the three phones. All three phones also have a 48 megapixel mode, but this mode does not always produce the best results.
The Redmi K20 Pro, OnePlus 7, and Xiaomi Mi 9 all offer similar camera performance. The 1.7 aperture allows for more background blur in non-portrait shots, and the 12 megapixel setting produces good detail. The 48 megapixel mode is not always the best option, however.
