The Xiaomi Mi MIX 2S has been launched at an event in China. With no major design changes, the second-generation bezel-less smartphone scored high on its camera capabilities. During the launch event, Xiaomi stressed on the amazing DxOMark photography score of 101 that the Mi MIX 2S achieved. At that score, the Mi MIX 2S should theoretically surpass the current best Samsung Galaxy S9+. But, that’s not what is meant by the ‘best smartphone camera ever’.

All new smartphones are religiously subject to DxOMark testing which scores smartphones on the bases on their camera quality. Now this includes still photo and video output. The Xiaomi Mi MIX 2S, differs from the Mi MIX 2, primarily in the camera department. It includes a dual-camera setup at the back with a combination of 12-megapixel wide angle lens and 12-megapixel telephoto lens. However, what makes the system powerful is the underlying AI technology that helps deliver quality images.

The setup includes a Sony IMX 363 sensor with f/1.8 aperture and 1.4µm pixels which is claimed to allow 25 percent more light more detailed low-light shots. The second camera utilizes a smaller 1/3.4-inch sensor combined with an equivalent 46mm telephoto lens for zooming. The camera features include AI-based scene selection, Portrait Mode, dual-pixel autofocus, 4-axis OIS, optical zoom, and hardware-level multi-frame noise reduction.


Xiaomi says the Mi MIX 2S got a DxO score of 101 for photography, the highest among smartphones. However, the actual score is 97. DxOMark says the overall score of the Mi MIX 2S is 97, a little behind the Galaxy S9+ and Google Pixel 2. “At an overall DxOMark score of 97, the Mi MIX 2S runs neck-and-neck with some high-end devices from more established manufacturers such as Apple, Google, and Samsung,” the firm says.

The Mi MIX 2S achieves a photo sub-score of 101 points, same as the iPhone X. The standout feature of the Mi MIX 2S is its “excellent phase detection autofocus system that is fast, accurate and very repeatable, together with its nice balance between texture preservation and noise reduction.” As DxOMark says, “In low light, the Xiaomi Mi MIX 2S renders some of the smoothest files we’ve seen, and luminance noise is very well-controlled in outdoor images, too.”

In Video score, the Mi MIX 2S achieves only 88 points, which is lower than the still photo performance. The main video strengths include excellent autofocus system and electronic stabilization system. Noise is fairly well-controlled as well, however, the dynamic range is found as a little limited in some clips. Below are some of the test shots by DxOMark with the Mi MIX 2S.

Overall, the photo sub-score of 101 is among the best the firm has rated. The performance is good in all lighting conditions, super-fast and accurate autofocus, as well as bold color rendition. “The Xiaomi Mi MIX 2S strikes a nice balance between noise and texture, too, and although it doesn’t quite offer class-leading sharpness in outdoor pictures, it’s not bad, and its low-light results are some of the smoothest we’ve seen,” the firm concludes. However, for those looking at purchasing the smartphone for the video skills, Mi MIX 2S is considered ‘run-of-the-mill’.
