Xiaomi Mix Fold 4 is here: thinner and lighter body, SD 8 Gen 3 and 5x periscope camera

Foldables in China are developing rapidly - slimming down in size while offering more powerful chipsets, cameras and larger batteries. Xiaomi’s new Mix Fold 4 is impossibly thin and light and it’s going directly at the recently launched Samsung Galaxy Z Flip6 and Honor Magic V3 while offering a larger main display, four rear cameras including a 5x periscope lens.

At just 226 grams, Mix Fold 4 weighs as much as Honor’s Magic V3 and it’s nearly as thin - 4.59mm unfolded and 9.47 mm in its folded state. Xiaomi went with a curved frame design with the sides tapering into the aluminum frame.

Mix Fold 4’s internal structure features T800H high-strength carbon fiber which is remarkably light while offering a 300% improvement in impact resistance compared to the Mix Fold 3.

This is also the first Xiaomi foldable with an IPX8 rating, making it water resistant up to 1.5 meters for 30 minutes.

There’s a 6.56-inch LTPO OLED cover display with FHD+ resolution, a 1-120 Hz adaptive refresh rate, and a 21:9 aspect ratio.

The star of the show is the 7.98-inch main panel which is made from Ultra Thin Glass (UTG) and also features FHD+ resolution and an adaptive 1-120 Hz refresh rate. Xiaomi claims both displays can crank out up to 3,000 nits peak brightness and each of them comes with a 20MP front-facing camera.

Like its recent flagship foldable rivals, Xiaomi Mix Fold 4 brings Qualcomm’s Snapdragon 8 Gen 3 chipset paired with up to 16GB RAM and 1TB storage.

Xiaomi didn’t spare any resources in the camera department where the Mix Fold 4 brings a Leica quad camera setup with Summilux lenses.

The main shooter features a 23mm equivalent 50MP main sensor with f/1.7 aperture and OIS. You also get a 50MP 2x portrait sensor (47mm) and a 10MP periscope with 5x optical zoom and 115mm equivalent lens. The fourth shooter on the back is a 15mm equivalent 12MP ultrawide lens.

Mix Fold 4 boots Xiaomi HyperOS based on Android 14 and packs a 5,100mAh Xiaomi Surge battery with 67W wired and 50W wireless charging.

Xiaomi Mix Fold 4 in black, white and blue

Xiaomi Mix Fold 4 comes in black, white, and blue colors. Pricing starts at CNY 8,999 ($1,237) for the 12/256GB trim and goes up to CNY 9,999 ($1,375) for the 16/512GB version and CNY 10,999 ($1,513) for the top-of-the-line Mix Fold 3 with 16GB RAM and 1TB storage.
