On the evening of July 19, the "2024 Lei Jun Annual Speech" was held as scheduled. At the press conference, Xiaomi's fourth-generation large-folding screen mobile phone MIX Fold 4 was first launched, with a starting price of 8,999 yuan. It is claimed to be the most advanced, sophisticated, and lightest fully-equipped large-folding flagship in the history of Xiaomi mobile phones.

Xiaomi MIX Fold 4 offers a new "Gentian Blue" color. This "Gentian Blue" is a dark ink blue color with a strong overall business atmosphere.

The "Gentian Blue" back cover is made of ultra-thin fiberglass technology, not traditional glass. This material can be made thinner and lighter, and has higher strength. The feel is not much different from AG glass, and it will not leave sweat stains and fingerprints when held for a long time.

The camera module of Xiaomi MIX Fold 4 has changed a lot. Although it is still located at the top of the body, its shape has become a "shield". There is a fine grid texture on the "shield" lens module, and the silver Leica logo is printed on one side of the four cameras.

Lightness and thinness are the biggest innovative highlights in the design of Xiaomi MIX Fold 4. Xiaomi MIX Fold 4 weighs 226 grams, has a single-side thickness of 4.59mm, and is only 9.47mm thick when folded. It adopts a metal middle frame and a four-micro-curved body design. When closed, the grip feel of the whole machine is no different from that of a traditional flagship straight-screen machine.

According to the official introduction, in terms of the overall stacking of the machine, the machine uses a three-layer, five-sided three-dimensional motherboard for the first time. The motherboard is equipped with 2545 components and can carry 2.3 times more components than a single-layer motherboard in the same area. The length of the motherboard is shortened by 11.5mm compared to the second generation, leaving a lot of space for the battery.

Xiaomi has also invested heavily in a "full carbon fiber structure" for it, which is said to have 100% carbon fiber hinge floating plate, 100% carbon fiber screen lining, and 100% carbon fiber middle frame battery compartment lining; it uses T800H high-strength carbon fiber, and its impact resistance is increased by 300%.

Xiaomi Mi MIX Fold 4 is equipped with Mi Keel Hinge 2.0, which has 12 teeth and adopts a three-stage connecting rod structure in the form of ultra-fine water droplets. The overall volume is reduced by 34% and the weight is reduced by 16%. 1800MPa ultra-strong steel accounts for 82.6%, and the hinge folding life exceeds 500,000 times. In terms of experience, the texture of the hinge of Xiaomi Mi MIX Fold 4 is good, the damping is moderate, and it is not loose.

Xiaomi MIX Fold 4 is also IPX8 waterproof, which is also Xiaomi's first folding screen that supports IPX8 waterproof.
