Xiaomi 18 Fold brings a wide foldable design to China

The Xiaomi 18 Fold is a short, wide foldable phone announced in China on September 7, 2026. It combines a 5.38-inch outer display, a 7.58-inch inner display, Xiaomi XRING O3, a 6,000mAh battery and a Leica-branded triple-camera system in a 219g body. China launch prices run from RMB 10,999 to RMB 15,999, while no official US launch or local MSRP was confirmed as of September 12, 2026.

The reported China retail start was September 10, separate from the announcement date. For US readers, that distinction matters: a Chinese-market unit is not the same thing as an officially sold US product.

A passport-style foldable with two different jobs

The Xiaomi 18 Fold takes the usual book-style foldable and makes it shorter and wider. Closed, its 117.8 × 83.6 × 10.68mm body presents a compact outer screen. Open, the phone measures 117.8 × 163.8 × 5.02mm and reveals a much broader tablet-like workspace.

That format changes the emphasis of the device. The outer display is designed for ordinary phone tasks, while the inner panel gives apps more room for reading, multitasking and media. The inner screen uses a 7.58-inch AMOLED panel with a 2364 × 1672 resolution; the outer screen is a 5.38-inch AMOLED panel at 1712 × 1168.

Both displays use LTPO technology with adaptive refresh rates from 1 to 120Hz. Xiaomi also lists peak brightness of up to 4,000 nits for each panel. Those figures describe the hardware; they do not, by themselves, establish battery life or outdoor viewing performance in every situation.

The hands-on footage adds useful physical context: it shows the hinge, crease, camera samples and HyperOS multitasking, including two apps displayed side by side. It is hands-on context rather than a standardized battery, thermal or benchmark test.

Xiaomi 18 Fold specifications at a glance

The storage options make the top configuration notably different from the entry model: the range runs from 12GB of RAM with 256GB of storage to 16GB with 1TB. The Ceramic Edition is available in the 16GB+1TB configuration.

Xiaomi XRING O3, memory and battery

Xiaomi XRING O3 is the phone’s in-house processor. It uses a 3nm process and combines a 10-core CPU with a 16-core G2-Ultra NX GPU and a quad-core NPU. Xiaomi reports 200 TOPS of tensor performance and says on-device decoding is 45% faster than its previous-generation flagship processor.

The technical analysis of the chip used a development board, not a finished Xiaomi 18 Fold. That makes it useful for understanding the processor’s architecture, but its benchmark results should not be treated as retail-phone scores.

A separate owner result reached 4,475,718 points in AnTuTu on a 16GB+1TB retail unit under favorable conditions: the phone was folded, without a case, in airplane mode and performance mode, with the battery at 100% and the device at 25°C. Results reportedly ranged from 3.02 million to 4.47 million. That is an individual, non-standard result—not a general performance guarantee.

The battery is one of the phone’s headline hardware choices. Its 6,000mAh silicon-carbon pack supports 67W wired HyperCharge and 50W wireless HyperCharge. Xiaomi also describes 20% high-silicon content and energy density of up to 920Wh/L. Those are component and charging specifications, not a measured endurance figure.

Leica cameras: a flexible three-camera setup

The rear system includes three cameras: a 200MP main camera, a 50MP periscope telephoto camera and a 50MP ultrawide camera, with Leica branding.

The main camera is listed with a 1/1.56-inch HP5 sensor, an f/1.7 aperture, optical image stabilization and a 23mm-equivalent focal length. The telephoto offers a 3.5× optical zoom, an f/2.8 aperture, optical stabilization and an 80mm-equivalent focal length. The ultrawide camera uses a 17mm-equivalent focal length and an f/2.4 aperture.

The combination gives the Xiaomi 18 Fold a broader shooting range than a foldable with only a main and ultrawide camera. It does not, however, prove that the phone will produce better images than a particular Apple or Samsung model. Camera quality depends on processing, lighting, stabilization and the specific comparison conditions.

Video recording is listed at up to 8K at 24 frames per second, with 4K recording at 30 or 60 frames per second. Dolby Vision is also reported for 4K recording.

China pricing and US availability

Xiaomi’s official China launch prices are configuration-specific:

These are China launch prices, not US retail prices. Currency conversions can change with exchange rates, and they do not account for taxes, import costs, retailer margins or differences in support.

As of September 12, 2026, no official US launch or local MSRP was confirmed. The same current status applied to the other markets tracked for this launch, including Germany, Spain, France, Italy, the Netherlands, Poland and Brazil. Third-party imports, if offered, should not be confused with official local availability.

What the Xiaomi 18 Fold means for US buyers

The hardware proposition is straightforward: the Xiaomi 18 Fold trades the tall, narrow profile of many book-style foldables for a wider outer body and a more square inner workspace. It also brings a large battery, a three-camera Leica system and Xiaomi XRING O3 to a 219g design.

The practical decision is less straightforward. There is no confirmed US MSRP or official US retail launch as of September 12, 2026. That leaves the China launch price as useful context, but not as a reliable estimate of what an imported device would cost in the United States.

For readers watching the category rather than buying immediately, the Xiaomi 18 Fold is an important design statement: a foldable can aim for a compact passport-style exterior without giving up a large inner display. Its specifications are ambitious. Its international purchase path remains the bigger question.
