Xiaomi 18 Fold Set for September 7 Launch With New Xring O3 Chip

Xiaomi is preparing to unveil the Xiaomi 18 Fold and Xiaomi Pad 9 Pro Max in China on September 7, with both devices set to debut the company’s latest in-house Xring O3 processor. The foldable is expected to mark a major step in Xiaomi’s push toward wider book-style foldables, while the new silicon highlights the company’s growing effort to reduce dependence on third-party flagship chip platforms. Xiaomi is also expected to introduce new electric vehicles at the same event.

The foldable-phone market is entering another important phase. As manufacturers compete to make large-screen devices thinner, faster and more practical, Xiaomi is preparing to bring its own answer to the segment with the Xiaomi 18 Fold.

Xiaomi has now officially scheduled its autumn flagship event for September 7 at 7 p.m. local time in China, where the company will introduce the 18 Fold alongside the Xiaomi Pad 9 Pro Max. Both products are confirmed to debut Xiaomi’s new Xring O3 AI flagship processor, making the event as much about Xiaomi’s semiconductor ambitions as its new hardware.

Xiaomi 18 Fold to Bring a New Direction for Foldables

The Xiaomi 18 Fold is expected to be the company’s next major book-style foldable following the Mix Fold 4. Reports indicate that Xiaomi is moving toward a wider internal-screen format, giving the device a tablet-like experience when unfolded while retaining a conventional smartphone form factor when closed.

Recent images and reports suggest a redesigned body with a horizontal camera arrangement and a wide inner display. The device is reportedly being positioned as a flagship rather than simply another experimental foldable, putting it into direct competition with premium foldable phones from Samsung, Honor and other manufacturers.

According to current reports, the phone could feature a 7.76-inch internal display and a 6.56-inch cover display, both using LTPO technology and supporting adaptive refresh rates up to 120Hz. A 6,000mAh battery and high-speed charging are also among the specifications reported ahead of the launch, although Xiaomi has not yet publicly confirmed the complete hardware configuration.

The camera system is also expected to be a major part of the phone’s appeal. Current specifications listings point toward a 200-megapixel primary camera alongside additional 50-megapixel and 200-megapixel sensors. These specifications should still be treated as pre-launch information until Xiaomi publishes the final configuration.

Xring O3 Is the Real Technology Story

The most significant development may not be the foldable screen at all. It is the processor powering it.

The Xiaomi 18 Fold will become the first smartphone to debut the company’s Xring O3 processor, while the Pad 9 Pro Max will use the same silicon. The move demonstrates Xiaomi’s increasingly ambitious strategy of developing proprietary computing hardware for its flagship products.

The Xring O3 is reported to use a 3nm manufacturing process and a 10-core CPU configuration, with clock speeds reaching up to 4.35GHz. It also incorporates a 16-core G2-Ultra NX GPU. Xiaomi has claimed substantial improvements in graphics performance and power efficiency compared with its previous generation, though independent real-world testing will ultimately determine how those claims translate into consumer devices.

The chip’s importance extends beyond conventional smartphone performance. Xiaomi has positioned the Xring O3 as an AI-focused processor, distributing acceleration capabilities across several parts of the platform, including the CPU, GPU, ISP, DPU and dedicated AI-related components. Reports also indicate support for LPDDR6 memory.

That combination becomes particularly interesting in a foldable smartphone, where manufacturers have to balance high performance against thermal limitations, battery life and the physical constraints of a thin folding chassis.

Xiaomi Is Pairing Its Chip With Chinese-Made LPDDR6 Memory

Another important element of the 18 Fold’s hardware strategy is its memory technology.

Reuters reported that China’s ChangXin Memory Technologies, or CXMT, will supply advanced LPDDR6 DRAM for Xiaomi’s upcoming foldable. Xiaomi has confirmed that the 18 Fold’s Xring O3 processor is designed to support the newer memory standard.

The development gives the 18 Fold an unusual degree of domestic technology integration. Instead of relying entirely on foreign-designed processors and memory platforms, Xiaomi is bringing together its own application processor with memory supplied by a Chinese semiconductor manufacturer.

For China’s smartphone industry, that is strategically significant. It reflects the broader push to develop competitive domestic semiconductor capabilities across processors, memory, packaging and AI acceleration.

Pad 9 Pro Max Will Share the Same Silicon

The Xring O3 will not be limited to Xiaomi’s foldable.

The company is also preparing the Xiaomi Pad 9 Pro Max, which will debut with the same processor. The tablet has already appeared in benchmark listings, providing an early indication of the performance Xiaomi is targeting. A recent Geekbench listing identified the device under model number M367FC.

Reports have suggested a battery capacity exceeding 10,000mAh and 120W wired charging, although Xiaomi has yet to disclose the tablet’s complete specifications. The large-screen device is expected to target demanding workloads such as video editing, drawing and intensive multitasking.

Launching the same proprietary processor across both a foldable smartphone and a flagship tablet could also help Xiaomi establish the Xring platform as a broader computing ecosystem rather than a chip designed for a single flagship handset.

Xiaomi’s September 7 Event Goes Beyond Smartphones

The September 7 event will not be limited to mobile hardware.

Xiaomi is also scheduled to introduce three vehicles — the N70 Pro, N70 Max and N90 Max — at the same event. The combination of smartphones, tablets, proprietary processors and electric vehicles illustrates how far Xiaomi has expanded beyond its traditional identity as a smartphone manufacturer.

That broader ecosystem is becoming an increasingly important part of Xiaomi’s strategy. Its hardware business now spans smartphones, tablets, connected devices, semiconductor technology and electric vehicles, with software and AI increasingly tying those products together.

A Crucial Test for Xiaomi’s Foldable Ambitions

The Xiaomi 18 Fold arrives at a time when foldable smartphones are moving from novelty products toward mainstream premium devices.

The challenge is no longer simply producing a phone that folds. Manufacturers must solve durability, hinge reliability, battery capacity, software optimisation, camera performance, weight and thickness while maintaining flagship-level performance.

Xiaomi’s approach with the 18 Fold appears to be to attack several of those challenges simultaneously: a wide-format foldable design, high-end cameras, a large battery, advanced memory and a proprietary flagship processor.

Whether that combination can compete with established foldable platforms will become clearer after the September 7 launch. For now, however, the event represents something bigger than another smartphone announcement: it is a demonstration of how Xiaomi is attempting to control more of the technology stack behind its flagship products.

What to Expect on September 7

Xiaomi’s September 7 event is now officially confirmed for China, with the Xiaomi 18 Fold and Xiaomi Pad 9 Pro Max confirmed among the headline products and the Xring O3 confirmed as the processor powering both devices.

Pricing, detailed global availability and the final specifications of both products remain among the major pieces of information Xiaomi has yet to reveal. Those details could determine whether the 18 Fold remains primarily a China-focused flagship or becomes a serious international challenger in the rapidly expanding foldable market.

For Xiaomi, the bigger message is already clear: its next generation of flagship hardware is increasingly being built around technology the company controls itself.
