Xiaomi has officially launched the Xiaomi 18 Fold in China, introducing a new wide-format foldable phone with a 7.58-inch inner display and a 5.38-inch outer screen. The phone is positioned as a premium flagship and brings together Xiaomi’s new Xring O3 processor, a Leica-backed 200MP triple-camera system, and a 6,000mAh battery.
The Xiaomi 18 Fold also stands out for its relatively thin and light body. Xiaomi has focused on making a large foldable easier to carry while still packing it with high-end hardware.
Xiaomi 18 Fold gets a wide foldable design
The Xiaomi 18 Fold uses a book-style folding design, but its proportions are wider and more compact than some traditional foldables. When opened, it provides a large screen that is closer to a small tablet, while the outer display can be used like a normal smartphone.
The inner display measures 7.58 inches, while the cover screen measures 5.38 inches. Both displays use AMOLED technology and support a 120Hz refresh rate. Xiaomi has also given both screens a peak brightness of up to 4,000 nits under specified conditions.
The phone is about 5.02mm thick when unfolded and weighs around 219 grams. That is notable for a device with such a large folding display and a 6,000mAh battery.

200MP Leica triple camera leads the camera setup
Photography is one of the biggest highlights of the Xiaomi 18 Fold.
The main rear camera uses a 200MP sensor with an f/1.7 aperture and Leica optics. Xiaomi has paired it with a 50MP ultra-wide camera and a 50MP periscope telephoto camera.
The telephoto camera supports 3.5x optical zoom, giving users a dedicated lens for distant subjects instead of relying only on digital zoom.
The camera system also supports high-resolution video recording. The main camera can record 8K video at 24 frames per second, while slow-motion recording can reach 960 frames per second at 1080p under supported settings.
The three-camera setup gives the phone more flexibility for different types of photography:
- 200MP main camera for detailed everyday photos and cropping
- 50MP ultra-wide camera for landscapes, buildings and group shots
- 50MP periscope camera for long-distance photography and optical zoom
- Leica tuning and optics for Xiaomi’s premium photography experience
The front camera uses a 16MP sensor. It is designed mainly for video calls, selfies, and other front-camera tasks.
Xring O3 brings Xiaomi’s own flagship chip
Another major part of the Xiaomi 18 Fold is the Xring O3 processor.
Xiaomi is using its own 3nm Xring O3 chip in the phone. This is an important step in the company’s effort to develop more of its own smartphone silicon rather than relying completely on outside chip suppliers.
The Xring O3 has a 10-core CPU and a 16-core GPU, with CPU boost speeds reaching up to 4.35GHz according to published specifications. Reports on the chip also highlight its focus on AI processing and power efficiency.
The phone can also be configured with LPDDR6 memory. Xiaomi’s top model combines 16GB of RAM with 1TB of storage, giving users a large amount of space for apps, photos, videos, and other files.
The Xring O3 is therefore not just another component inside the phone. It is one of the main reasons the Xiaomi 18 Fold is being positioned as a flagship device.
Large 6,000mAh battery with fast charging
Foldable phones often have to balance a large screen with battery life, and Xiaomi has given the 18 Fold a 6,000mAh battery.
The phone supports 67W wired charging through USB-C and 50W wireless charging.
The battery capacity is particularly notable considering the phone’s thin design. Xiaomi has managed to fit a large battery into a body that is only about 5mm thick when unfolded.
Actual battery life will still depend on factors such as screen brightness, network conditions, gaming, camera use, and whether the large inner screen is used for long periods.
Thin body is one of the biggest design highlights
The Xiaomi 18 Fold is designed to be more compact than many large foldable phones.
At about 219 grams, it is relatively light for a foldable with a 7.58-inch internal screen. When unfolded, the phone is only around 5.02mm thick, while the folded thickness is considerably greater because the two halves of the device sit together.
Xiaomi has also given the phone an IP59 rating for protection against dust and water under the specified testing conditions.
The phone is available in black, a red finish, and a warm gold-white option, while Xiaomi also offers a ceramic special edition at the top end of the range.
Xiaomi 18 Fold price and availability
The Xiaomi 18 Fold has launched in China. The starting model comes with 12GB of RAM and 256GB of storage.
The price increases with additional storage and memory, with the highest standard configuration offering 16GB of RAM and 1TB of storage. Xiaomi is also offering a ceramic special edition at a higher price.
| Variant | China launch price |
|---|---|
| 12GB + 256GB | CNY 10,999 |
| 12GB + 512GB | CNY 11,999 |
| 16GB + 512GB | CNY 12,999 |
| 16GB + 1TB | CNY 14,999 |
| Ceramic 16GB + 1TB special edition | CNY 15,999 |
The Xiaomi 18 Fold has been announced for the Chinese market, but Xiaomi has not confirmed a wider international launch at this stage.
A foldable built for productivity and entertainment
The large inner display gives the Xiaomi 18 Fold a clear advantage for tasks that benefit from more screen space.
Users can open several apps, read documents, browse the web, edit content, watch videos, and use other tablet-style applications on the larger screen. The wide design also gives Xiaomi room to create a more comfortable layout for multitasking.
The outer display remains important because users do not need to unfold the phone for every small task. Calls, messages, quick searches, notifications, and other simple activities can be handled from the cover screen.
This two-screen approach is one of the main reasons people choose foldable phones in the first place.
Gaming gets an AI graphics boost
The Xring O3 is also paired with new graphics technology designed to improve mobile gaming.
The phone uses Arm’s Mali G2-Ultra NX GPU, which includes an AI-based graphics accelerator. The technology is designed to support features such as AI upscaling, neural frame-rate upscaling, and neural denoising.
These features are intended to improve image quality and frame rates without requiring a matching increase in power use. Support for individual graphics features and games will depend on software integration.
That makes the Xiaomi 18 Fold more than a large-screen productivity device. Its hardware is also aimed at people who want to play demanding games on a foldable.
Why the Xiaomi 18 Fold matters
The Xiaomi 18 Fold shows how quickly premium foldable phones are changing.
Instead of simply making a conventional phone that folds in half, Xiaomi has focused on three areas at the same time: a large and bright display, flagship-level camera hardware, and a custom processor.
The 200MP Leica camera gives the phone a strong photography focus, while the Xring O3 shows Xiaomi’s growing interest in designing its own chips. The 6,000mAh battery and relatively light body also address two common concerns with foldable phones.
Its biggest limitation for buyers outside China is availability. Xiaomi has not yet confirmed when the 18 Fold will reach other markets.
Final verdict
The Xiaomi 18 Fold is an ambitious flagship foldable that combines a large 7.58-inch inner display with a compact outer screen, a 200MP Leica triple-camera system, Xiaomi’s new Xring O3 chip, and a 6,000mAh battery.
Its relatively low weight and thin unfolded body make the design particularly interesting, while 67W wired and 50W wireless charging add to the premium package.
For now, the biggest question is not the hardware but global availability. Xiaomi has launched the 18 Fold in China, but an international release has not been confirmed. If the phone eventually reaches more markets at a competitive price, its combination of camera hardware, custom silicon, large displays, and slim design could make it a serious competitor in the premium foldable market.
