Xiaomi 18 Fold and Huawei Mate XT 2: What to Expect From the September 7 Foldable Launches

The September 7 foldable-phone launches are shaping up as a contest between two different ideas of what a large-screen phone should be. Xiaomi’s 18 Fold is positioned as a compact “mid-fold” handset that should be easier to use when closed, while Huawei’s Mate XT 2 continues the company’s push toward a tri-fold phone that opens into a much larger tablet-like display.

Both launches are scheduled for China, and both arrive as the foldable market moves toward larger book-style and multi-fold devices. The important caveat is timing: several specifications, prices, software features, and international-availability claims remain reports or predictions rather than final product facts.

Xiaomi 18 Fold: a compact foldable with flagship ambitions

Xiaomi has confirmed that the Xiaomi 18 Fold will launch in China on September 7. The company has also revealed the device’s unusual display strategy: a 5.38-inch cover screen when closed and a 7.58-inch folding screen when opened. That gives the phone a smaller external footprint than many conventional book-style foldables while still providing a larger canvas for video, multitasking, and productivity. 3739

That positioning is the central idea behind the “mid-fold” label. Instead of treating the closed phone as a narrow compromise, Xiaomi appears to be emphasizing a more manageable, one-hand-friendly form that can still serve as a premium smartphone before opening into a larger display. The exact dimensions, weight, hinge specifications, and durability ratings should wait for the launch presentation.

Confirmed and strongly reported Xiaomi hardware

The Xiaomi 18 Fold is confirmed to use Xiaomi’s Xring O3 flagship processor. Xiaomi has also confirmed Leica co-engineered cameras, although the complete sensor configuration and the claim that the phone will use a specific triple-camera setup have not been established by the strongest available sources. 3941

Another important detail is the phone’s memory technology. CXMT has said it will supply LPDDR6 DRAM for Xiaomi’s upcoming flagship foldable, identifying the Xiaomi 18 Fold as the first commercial phone associated with that memory platform. Reuters describes the development as a notable step for China’s domestic memory supply chain. 33

Reports also describe a revised hinge and a design intended to make the crease less visible, but those details should be treated as pre-launch reporting until Xiaomi publishes a complete specification sheet. 39

What is not confirmed yet

A number of widely circulated Xiaomi 18 Fold claims remain tentative:

• a price of approximately ¥12,000;
• China-only availability;
• the name “Surge OS 4” and MiMo on-device AI features;
• a complete Leica-tuned triple-camera specification;
• battery capacity, charging speeds, and other detailed hardware figures;
• the full list of products appearing at Xiaomi’s September 7 event.

Some reporting expects Xiaomi to show the Pad 9 Pro Max alongside the foldable, but the complete event lineup has not been reliably established. The safest conclusion is that Xiaomi has confirmed the date, display sizes, Xring O3 platform, Leica camera partnership, and LPDDR6 connection—not every specification circulating online.

Huawei Mate XT 2: the tri-fold alternative

Huawei has confirmed that the Mate XT 2 Ultimate Design will be unveiled in China on September 7. Unlike Xiaomi’s compact mid-fold concept, Huawei is extending its tri-fold strategy: the device is designed to fold across multiple sections and open into a much larger screen. 1927

Huawei opened Chinese pre-orders on August 31. Reservation information reported by multiple outlets lists a ¥1,000 deposit, with final-payment timing tied to September 7. The pre-order materials also reveal multiple memory and storage configurations, including privacy-display variants and a high-end 2TB option in some reports. 172129

The privacy display is one of Huawei’s clearest differentiators. Huawei says the technology is designed to keep the screen readable from the front while limiting visibility from wider side angles. That makes the feature more practical than a purely cosmetic edition: it targets people who use a large-screen phone in public spaces. 19

Reports also point to a redesigned folding mechanism intended to protect more of the flexible display when the phone is closed. However, the precise hinge design, cover-screen dimensions, chipset, final price, and international availability remain incomplete or unconfirmed. 1832

Xiaomi and Huawei are choosing different trade-offs

The two phones are not direct copies of one another. Xiaomi’s apparent priority is balance: a phone that is relatively compact when closed but still expands meaningfully when opened. Huawei’s priority is maximum screen area and a more ambitious multi-fold format.

That distinction matters because foldables still ask buyers to accept compromises. Larger screens can improve reading, video, and multitasking, but additional hinges and display sections can increase complexity, thickness, weight, and cost. A smaller closed form can improve everyday handling, but it may provide less space than a full-size tri-fold when opened.

The September 7 launches therefore offer two competing answers to the same product question: should a foldable feel more like a conventional phone first, or more like a tablet that happens to fit in a pocket?

Apple’s expected foldable raises the stakes—but remains unconfirmed

The Xiaomi and Huawei launches are taking place just before Apple is widely expected to enter the foldable category. Reports describe a first book-style foldable iPhone with a cover display of roughly 5.5 inches, an inner display of about 7.8 inches, and a price above $2,000. Apple has not confirmed the product, its specifications, its price, or the date of any launch event. 58

Reporting also disagrees over whether Apple’s September event would take place on September 9 or September 10. That uncertainty makes it inappropriate to describe the rumored iPhone as a confirmed September 9 product announcement.

Even so, analysts expect Apple’s entry to have an outsized effect on the category. IDC estimates cited by 9to5Mac project more than 10 million foldable-iPhone shipments in the first year, at an expected price of about $2,500. That is a forecast, not an Apple sales commitment, but it illustrates why competitors are focusing on premium book-style and multi-fold designs. 3

The foldable market is growing, but not without problems

Market forecasts point to continued growth in 2026. Counterpoint projections cited by 9to5Mac put overall foldable shipments up 21% year over year and estimate that book-style devices could account for 76% of shipments, compared with 52% in 2025. 3

Omdia figures reported by Forbes similarly show book-style foldables gaining share while clamshell shipments weakened sharply in the first half of 2026. The same reporting says 5.1 million foldables shipped globally in that period. 7

Those numbers do not mean foldables have become mainstream. High prices, durability concerns, visible creases, repair costs, thicker designs, and inconsistent software optimization remain barriers. The category is expanding from a premium base, which explains the emphasis on flagship processors, cameras, local component supply, privacy features, and larger productivity screens.

What to watch on September 7

The most consequential announcements will be less about rumor-sheet volume and more about practical trade-offs:

1. Xiaomi’s final price and availability: These will determine whether the 18 Fold is a China-focused showcase or a serious international premium-phone competitor.
2. The real-world size and weight: The mid-fold concept only works if the closed phone is genuinely easier to carry and use than conventional book-style foldables.
3. Huawei’s final tri-fold design: The hinge, display protection, and privacy-screen implementation will show whether the Mate XT 2 improves the usability concerns associated with earlier multi-fold phones.
4. Software support: Large foldables need reliable multitasking, app scaling, and tablet-style workflows—not just impressive hardware.
5. Apple’s response: If Apple enters the market with a high-volume premium device, it could expand consumer awareness of foldables while intensifying competition among Xiaomi, Huawei, Samsung, and other established manufacturers.

The clearest pre-launch verdict is that Xiaomi and Huawei are not simply releasing two more foldable phones. Xiaomi is testing whether a foldable can be compact enough to replace a conventional flagship, while Huawei is testing how far the tri-fold format can go. The final prices, software, durability, and regional availability will determine whether either approach moves beyond China’s premium-device market.
