Xiaomi 18 Fold Launched With XRing O3, 7.58-Inch Display and 6,000mAh Battery
Xiaomi has officially launched the Xiaomi 18 Fold, a new wide-format foldable smartphone that takes a different approach to the traditional book-style design. The phone debuted in China on September 7, 2026, with Xiaomi positioning it around portability, a large tablet-like inner display and its latest in-house XRing O3 processor.
Unlike many conventional foldables, the Xiaomi 18 Fold uses a wider form factor designed around an approximately √2:1 paper-like aspect ratio. When unfolded, it provides a 7.58-inch display, while the outer screen measures 5.38 inches.
The phone also combines a Leica camera system, 6,000mAh battery, 67W wired charging and 50W wireless charging in a 219-gram body.
Xiaomi 18 Fold Price in China
The Xiaomi 18 Fold starts at ¥10,999 in China.
The available configurations are:
| Variant | Price |
|---|---|
| 12GB + 256GB | ¥10,999 |
| 12GB + 512GB | ¥11,999 |
| 16GB + 512GB | ¥12,999 |
| 16GB + 1TB | ¥14,999 |
| 16GB + 1TB Ceramic Edition | ¥15,999 |
The Ceramic Edition is a limited version with a different rear construction and is priced higher than the standard 1TB model.
The phone went on sale in China from September 10, 2026. Xiaomi’s official store currently lists the Xiaomi 18 Fold from ¥10,999.
A New Wide-Format Foldable Design
The Xiaomi 18 Fold is designed around a wider foldable form factor rather than the tall proportions commonly associated with traditional book-style foldables.
It has a 5.38-inch outer screen and a 7.58-inch inner display. Both screens use a paper-like √2:1 aspect ratio, which Xiaomi says is intended to make switching between the folded and unfolded displays more natural.
The phone measures 117.8 × 83.6mm when folded, with a folded thickness of 10.68mm. When unfolded, it reaches a thickness of just 5.02mm and weighs approximately 219 grams.
Xiaomi also uses a redesigned Dragon Bone Hinge with a three-stage linkage structure. The company combines it with a 7-series aluminium frame and Xiaomi Dragon Crystal Glass 3.0. The inner display uses a dual-layer ultra-thin glass structure.
7.58-Inch 120Hz Inner Display
The main display measures 7.58 inches, giving the Xiaomi 18 Fold a tablet-like viewing area when opened.
The outer display measures 5.38 inches, making the folded device significantly closer to a compact passport-like shape than a conventional narrow foldable.
Both displays support an LTPO refresh rate from 1Hz to 120Hz, allowing the phone to vary the refresh rate depending on the content and usage scenario. Xiaomi lists up to 4,000 nits of peak brightness under specified conditions.
The inner screen also uses an anti-reflective film designed to improve visibility.
XRing O3 Is the Main Performance Upgrade
The Xiaomi 18 Fold is the first smartphone to use Xiaomi’s new XRing O3 flagship processor.
The chip is built on a 3nm process and uses a 10-core all-big-core CPU design. Xiaomi has also introduced a 16-core G2-Ultra NX GPU with the platform.
Xiaomi previously reported an AnTuTu score of more than 5.22 million points for the XRing O3. That figure comes from Xiaomi’s testing environment, so independent benchmark results may differ.
Another major change is memory technology. The 16GB + 1TB version uses LPDDR6 RAM, while lower configurations use LPDDR5X memory.
Leica Triple-Camera System
Photography is another major focus of the Xiaomi 18 Fold.
The phone has a Leica-branded triple-camera system consisting of:
- 200MP Leica main camera
- 50MP Leica periscope telephoto
- 50MP Leica ultra-wide camera
The periscope telephoto camera offers 3.5x optical zoom, giving the foldable a dedicated long-range camera rather than relying entirely on digital cropping.
Xiaomi has also focused on the way the foldable’s two displays can work alongside the camera system. The phone supports simultaneous dual-screen shooting, which can allow the subject and photographer to view different screen areas during certain shooting scenarios.
6,000mAh Battery and 67W Charging
The Xiaomi 18 Fold packs a 6,000mAh battery using Xiaomi’s Jinshajiang battery technology.
The phone supports 67W wired fast charging and 50W wireless charging. This is notable for a foldable with a relatively thin unfolded profile, as larger batteries are usually more difficult to accommodate in compact foldable designs.
Battery performance will naturally depend on how frequently the large inner screen is used, network conditions, brightness and application activity.
HyperOS and On-Device AI
The Xiaomi 18 Fold launches with HyperOS 4 and includes Xiaomi’s growing on-device AI ecosystem.
The XRing O3 platform has been designed with AI processing in mind, while Xiaomi also integrates its MiMo on-device models into the phone.
The large internal display is also designed for productivity. Xiaomi supports split-screen layouts that can divide the screen into multiple application areas, making it possible to work with several apps simultaneously.
Durability and Hinge Improvements
Foldable phones have traditionally faced questions around hinge and display durability, so Xiaomi has highlighted the engineering of the 18 Fold.
The new Dragon Bone Hinge uses a three-stage linkage system, while the inner screen combines dual-layer UTG glass with flexible materials. Xiaomi says the phone underwent extensive controlled drop testing and uses strengthened materials throughout the body.
Xiaomi also claims that the foldable’s crease averages no more than 30 micrometres in depth under its testing methodology. This is a manufacturer measurement rather than an independent durability test.
Colors and Ceramic Edition
The Xiaomi 18 Fold is available in Black, Warm Gold White and Nishino Red, while a limited Ceramic Special Edition is offered for the 16GB + 1TB configuration.
The Nishino Red finish is one of the more distinctive options, while the standard colors give the phone a more restrained appearance.
Xiaomi 18 Fold Availability
The Xiaomi 18 Fold launched in China, with the September 7 unveiling followed by sales beginning September 10.
As of the latest official Xiaomi listings reviewed, there is no confirmed India launch or global availability announcement for the Xiaomi 18 Fold. Xiaomi India’s current product listings do not include the device.
Indian buyers should therefore avoid treating unofficial imported pricing or expected India prices as official Xiaomi pricing.

What Makes the Xiaomi 18 Fold Different?
The most unusual part of the Xiaomi 18 Fold is its wide mid-fold format.
Instead of simply making a traditional foldable larger, Xiaomi has designed the device around a roughly √2:1 aspect ratio. The approach provides a wider inner canvas while keeping the outer display relatively compact.
The combination of a 7.58-inch inner screen, XRing O3 processor, 200MP Leica camera, 6,000mAh battery and 219-gram weight gives the phone a specification package that is clearly focused on portability and high-end hardware.
Xiaomi 18 Fold: Final Takeaway
The Xiaomi 18 Fold is a significant change from Xiaomi’s earlier foldable approach. It combines a wider form factor with a 7.58-inch inner display, 5.38-inch outer screen and 5.02mm unfolded thickness.
Its other major highlights include the XRing O3 3nm processor, Leica 200MP triple-camera system, 6,000mAh battery, 67W wired charging and 50W wireless charging.
The Xiaomi 18 Fold starts at ¥10,999 in China, with the range extending to ¥15,999 for the limited Ceramic Edition. For Indian readers, the important point is that official India availability has not been confirmed, so China pricing should not be presented as an India price.
