Charge faster with the world’s first 20W wireless quick charging
Wireless charging like you’ve never seen before
The days of slow wireless charging are in the past. New innovations have now made it possible to reach full charge in 90 minutes with wireless charging–that’s even faster than traditional 18W wired charging.
World’s highest resolution image sensor for smartphones so far
4 times the resolution, 3 times the light sensitivity
What does it mean to have a camera with 4 times as many pixels as the typical 12MP smartphone? It means that when you zoom in, there is still enough detail to create a quality photo. With the large 1.6μm 4-in-1 Super Pixel and 1/2” CMOS image sensor, photos are lively with color. In fact, Mi 9’s camera takes photos with more details than a 4K television.
All new AI triple camera – More than just another lens
A wider angle and a closer shot
The secret to amazing photography? Three essential lenses: wide angle, telephoto, and ultra wide-angle. Mi 9 has a lens with a view wider than typical lenses, and the camera is capable of correcting for distortion. It even supports macro photography, so there’s no limits to your creativity.
Shoot for the moon
Powerful Night and Moon modes
With the large 1.6μm 4-in-1 Super Pixel and 1/2” CMOS image sensor, Mi 9 takes the Xiaomi Night mode experience to another level. Then with Moon mode, zoom in to see the beams of moon in your photos.
20MP Beautify selfie camera
Front camera with AI portrait mode
The 20MP high resolution sensor can intelligently combine pixels into a single 1.8μm pixel, making photos brighter in dim light. With the improved AI Beautify and AI portrait modes, each selfie becomes dreamy masterpiece.
Holographic color scheme
Not a single color, but a blend of metallic reflection and rainbow hues
Feel the future with colors that move and sway with the light
If you’ve ever been intrigued by the mysteries of a starry night sky, then you will love the look of this phone. Made with nanometer-level coating, the finish brings out all the colors of the light as it hits the phone, creating a spectacular sight.
