Xiaomi announces Mi MIX with borderless display
The Mi MIX has a custom-made 6.4-inch, 2040x1080 pixel, 17:9 aspect ratio display that takes up 91.3% of the front. The display has really thin bezels on the top and sides, making it look nearly borderless. There is only one significant bezel, and that is at the bottom, where you will also find the front speaker and camera. The Mi MIX does not have physical buttons at the bottom and is the first Xiaomi phone with on-screen controls. The 17:9 aspect ratio means even with the on-screen buttons you still get full 16:9 area for your content.
The earpiece and proximity sensor are completely hidden and had to be reimagined. The Mi MIX uses a piezoelectric ceramic driver for the earpiece and an ultrasonic proximity sensor, which works through the display.
The body of the Mi MIX is made entirely out of ceramic, with ceramic back, ceramic frame, and ceramic buttons. The design uses a mortise and tenon joint for attaching the display to the body, instead of glue or other adhesives. The industrial design has been done by designer Philippe Starck.
Inside, the Mi MIX runs on a Qualcomm Snapdragon 821. The 128GB model gets 4GB of RAM while the 256GB model gets 6GB of RAM. The 256GB model also gets gold trim, with 18K gold accents on the camera lens and fingerprint sensor on the back. The back camera has 16 megapixel resolution with PDAF and 4K video, and the front camera is 5 megapixels. The phone also has dual SIM connectivity. The whole thing is powered by a 4,400mAh battery with Qualcomm Quick Charge 3.0 fast charging.
The Mi MIX is priced at RMB 3,499 ($515) for the 4GB/128GB model and RMB 3,999 ($590) for the 6GB/256GB model. Both variants come with a leather case.
