Finally, with 900 nits peak brightness, 700 nits overall brightness, and HDR10+ support, the display offers excellent viewing angles, depth and color contrast.

Powered by Xiaomi’s own AI algorithm, Mi MIX FOLD’s external and internal displays can generate images and videos in super-resolution and are even capable of doubling the resolution of pictures from 720p to 1440p. For video, the AI algorithm triples the resolution, enhancing the quality from 480p to 1440p.


Having received widespread acclaim for its dual speakers on previous devices, Xiaomi further elevated the sound system on Mi MIX FOLD by creating the first-ever smartphone quad speakers setup. The symmetrically designed dual 1216 speakers are positioned on either side of the screen and boast a large 0.65mm amplitude and 1.34cc-equivalent sound cavity. The speaker’s innate properties are strengthened by 15V Smart PA which drives the sound level up to 40% louder than that of Mi 10 Pro. Mi MIX FOLD inherits the legacy of the Mi 11 series with professional-grade tuning through SOUND BY Harman Kardon.

Mi MIX FOLD is the industry’s first smartphone to adopt true panoramic surround sound. Using Xiaomi’s own quad-speaker array algorithm, the device can realize 3D spatial audio field playback, which builds an additional sound dimension on top of the foundational dual speakers, creating a true 3D spatial audio listening experience.


Powered by Dolby Vision and a quad-speaker 3D panoramic sound system, Mi MIX FOLD is an absolute beast for viewing content, offering an immersive viewing experience with vivid colors, full-bodied sound quality and a super large display surface. The device also supports multi-window, allowing you to watch up to four videos in different windows on the display at the same time.

Mi MIX FOLD also offers a completely unrivaled gaming experience on a mobile device. At 8.01” in size, the device has more vertical space giving a much wider field of view than traditional smartphones. The bigger the screen, the better the work! Mi MIX FOLD’s super large display is the ultimate productivity booster for busy people on the go, supporting a wide range of highly practical work tools such as split-screen, multi-screen drag and drop, parallel windows, Desktop mode, AI meeting assistant, and many more.


Mi MIX FOLD debuts the Surge C1 processor – a professional image processing chip developed by Xiaomi. The product of two years of development and RMB 140 million in R&D investment, this chip provides exceptionally high performance while occupying low CPU and storage space. This enables it to service an improved 3A algorithm and low-light focus capabilities for more accurate autofocus, auto exposure and auto white balance, significantly improving image quality.

Mi MIX FOLD is also the world’s first smartphone with Liquid Lens technology, opening the era of bionic photography. The liquid lens uses the principle of human eye bionics, forming a lens-like structure with a transparent fluid wrapped in film, very different from traditional optical lenses. The radius of curvature of the spherical surface can be accurately changed thanks to a high-precision motor based on Xiaomi’s self-developed technology, which allows for 3X optical zoom, up to 30X telephoto, and a minimum focus distance of 3cm. One lens virtually covers the functions of two lenses. You can shoot micro-details up close, and gaze at magnificent rivers and mountains from a distance. The Liquid Lens also offers high light transmittance, ultra-low dispersion, and excellent resistance to extreme environments. It can maintain the fluid form in an environment from a low of -40°C to a high of 60°C, ensuring stable, long-lasting, and high-quality optics.

In addition, Mi MIX FOLD is also equipped with a 108MP pixel main camera and a 13MP ultra-wide angle camera with an impressive 123° field of view. The 108MP pixel main camera is equipped with a 7P lens, which can directly output 108MP pixel high-definition photos. The 123° ultra-wide angle camera supports smart switching, allowing an astounding field-of-view when shooting buildings and scenery. At the same time, AI ultra-wide-angle distortion correction is used to effectively improve the edge distortion of the picture. Not only can it eliminate the edge distortion of landscapes, it can also correct distortion on faces in ultra-wide group photos.
