The battery packs in the N70 Max and N90 Max have passed extreme tests including 500J bottom impacts, water fording, and 55°C full-charge needle puncture without thermal runaway. Xiaomi also launched the "Dragon Armor Battery Assurance Plan" offering lifetime warranty and new-car replacement in case of fire.

The N90 Max Explorer Edition represents Xiaomi's bold exploration of space. Built on the N90 Max, which features a larger body with seven seats and a combined range of 1,705km, the Explorer Edition introduces a new large five-seat layout with the industry's only original-design electric pop-up roof for SUVs. When raised, the interior transforms into a two-level LOFT with 2,110mm x 985mm of upper space, 2.29 meters of headroom, and 200kg load capacity, creating what Lei Jun described as "a truly movable house." The pop-up roof underwent rigorous testing including 44km/h rollover and 10,000 open-close cycles. Additional features include one-touch electric bed conversion, wood-grain aluminum flooring, floor heating, an independent compressor refrigerator, and smart electric doors.

With these four models, the Pengcheng "intelligent transformable large space SUV" series has formed a complete product matrix. Lei Jun stated that vehicles should not just be transportation but can become part of living space, "carrying work and passion, connecting career and family, accommodating dreams and distant horizons."

Three Chips Power the AI Ecosystem

On August 24, Xiaomi unveiled the next generation of Xuanjie chips: the AI flagship SoC Xuanjie O3, high-bandwidth AI accelerator Xuanjie O100, and smart driving high-compute AI chip Xuanjie D100. Together, these three chips form the advanced AI computing foundation for Xiaomi's full ecosystem, representing breakthroughs in high energy efficiency, high bandwidth, and high computing power.

At the September event, Lei Jun officially launched two devices powered by the Xuanjie O3: the Xiaomi 18 Fold and Xiaomi Pad 9 Pro Max. The 18 Fold, a "mid-fold" flagship, is Xiaomi's most advanced smartphone to date, developed over 20 months with more than 190 folding-related patents. It features the new Dragon Bone hinge with a three-link structure and 7-series aluminum alloy, passing over 80,000 drop tests. The device achieves a global-leading crease depth of less than 30μm and is the industry's first to mass-produce dual-layer UTG ultra-thin glass. It also debuts next-generation LPDDR6 memory, with Changxin Storage supplying the first domestic LPDDR6 for flagship terminals.

The Xiaomi 18 Fold is a comprehensive flagship with a 7.58-inch inner screen and 5.38-inch outer screen, both using Xiaomi's super pixel technology. It features a Leica triple camera system with a 200MP main sensor and 3.5x periscope telephoto, supporting simultaneous dual-screen shooting. The 6,000mAh stacked battery supports 67W wired and 50W wireless charging. Goodix Technology solutions are integrated, including an independent security chip with high-level certifications, touch control, ultra-narrow side fingerprint sensor, and a CoolPWM smart audio amplifier for premium sound quality.

The Xiaomi Pad 9 Pro Max, also powered by the Xuanjie O3 and HyperOS 4, achieves an AnTuTu score of 5.61 million - the highest ever for an Android tablet - thanks to its form factor and new capillary heat dissipation structure. It supports WPS for Pad, professional version of CapCut, and other productivity software, along with the Super Xiao Ai office suite and desktop-level expansion capabilities.

With these launches, the Xuanjie O3 has entered mass production. Lei Jun disclosed that the Xuanjie O100 and Xuanjie D100 will be commercially available next year, positioning Xiaomi among the very few companies globally that develop smartphone SoCs, AI accelerator chips, and smart driving chips simultaneously. He acknowledged that Xiaomi is still a newcomer in chips but expressed confidence: "No matter how many difficulties lie ahead, we believe that as long as we start chasing, we are on the road to winning."

A Systematic Breakthrough in Self-Developed Technology

In 2020, on Xiaomi's tenth anniversary, Lei Jun established "technology first" as a core principle, beginning the company's transformation from an internet company to a hardcore technology firm. A year later, Xiaomi announced its entry into smart EVs and restarted large-scale chip development, pledging over 100 billion yuan in core technology investment over five years. To date, Xiaomi has invested 105.5 billion yuan in core technology, with 21 billion yuan allocated to chips alone over a planned 500 billion yuan, 10-year commitment.

In 2025, Xiaomi launched the Xuanjie O1, mainland China's first 3nm flagship SoC, with over 1 million terminals shipped. The next-generation Xuanjie chips have completed R&D and testing, with the O3 now in commercial production. The Xiaomi MiMo large model has achieved a complete closed loop across language, multimodal, and voice capabilities, ranking first among open-source models globally on the ArtificialAnalysis comprehensive intelligence and Agent indices in April, and topping the OpenRouter weekly and monthly call volumes in July.

HyperOS has undergone a comprehensive bottom-layer reconstruction, fully connecting scenarios across people, cars, and homes. The latest HyperOS 4 integrates the MiMo large model and fully AI-powered Super Xiao Ai 2.0, enabling cross-ecosystem and cross-device collaboration. In the automotive sector, Xiaomi has delivered over 800,000 vehicles as of September 7 - a record for Chinese new-energy vehicle startups, achieved in just 29 months. The Pengcheng series, built on the Kunlun architecture, addresses common pain points of traditional extended-range vehicles with its disruptive intelligent transformable large space.

Over five years, Xiaomi has built a deep moat in core technologies across chips, AI, and OS, and established three smart factories for phones, cars, and home appliances. The Xuanjie chips now support the full ecosystem's AI computing needs, and Xiaomi has completed its pure electric and extended-range technology platforms. The September launch event showcased these achievements: the Xuanjie O3 and HyperOS 4 power the Xiaomi 18 Fold and Pad 9 Pro Max, the MiMo on-device model has been deployed on the 18 Fold, and the Kunlun architecture's three core technologies are fully realized in the new Pengcheng series. With sustained investment in chips, AI, and OS applied densely across its product lineup, Xiaomi is accelerating toward becoming a global leader in next-generation hardcore technology.
