Xiaomi’s Xring O3 Chip Targets a Flagship Foldable as the Company Pushes Toward Chip Independence

Xiaomi’s Xring O3 is the company’s second in-house smartphone system-on-chip, extending a strategy that reaches beyond branding a new processor. Xiaomi is using proprietary silicon to gain more control over key components, improve hardware-software integration and compete with rivals such as Huawei, Apple and Samsung. 3

The announcement comes as smartphone makers face weaker demand and higher memory and component costs. That makes a premium foldable a logical—if demanding—place to showcase Xiaomi’s chip ambitions.

What Xiaomi announced about the Xring O3

Xiaomi introduced the Xring O3 as the successor to its Xring O1. The company said the O3 had entered mass production. Sources familiar with the matter said Taiwan Semiconductor Manufacturing Co. (TSMC) would manufacture it using a 3-nanometre process. 3

The same sources said the processor is expected to power Xiaomi’s next flagship folding phone, with an initial shipment target of 200,000 to 300,000 units. Those details were attributed to anonymous sources rather than confirmed specifications from Xiaomi or TSMC. 3

A smartphone SoC combines core processing, graphics, artificial-intelligence and imaging functions. By designing more of that system itself, Xiaomi can seek tighter coordination between its chips, devices and software while reducing exposure to outside suppliers such as Qualcomm and MediaTek.

Why the foldable matters

The reported O3 foldable would place Xiaomi’s in-house silicon in the company’s premium segment, where manufacturers compete on distinctive designs, camera and AI features, battery efficiency and software—not only price.

It would also be aimed at a difficult market leader. Huawei shipped 1.6 million foldable phones in China in the second quarter and held 68% of the market, according to the figures cited in the reporting. Honor held 13.7% and Oppo 8.5%. 3

A 200,000–300,000-unit initial target would therefore suggest a focused flagship launch rather than an immediate mass-market replacement for Qualcomm-powered phones. It could give Xiaomi a controlled way to test whether its own chip can support a premium device before expanding its role across more models.

The Xring O1 provides an early benchmark

Xiaomi said products using the Xring O1—including smartphones, tablets and watches—had surpassed 1 million cumulative shipments since launch. Sources estimated that about 150,000 O1 smartphones had sold since the chip’s introduction in May 2025. 3

Those figures show both progress and the scale of the challenge. Xiaomi has moved from a first proprietary smartphone processor to a second-generation design, but the O3’s reported initial foldable volume would still be relatively limited compared with the company’s overall handset business.

Xiaomi is pursuing chip control during a smartphone slowdown

The O3 initiative is arriving amid pressure on the broader smartphone market. IDC forecast a 14% decline in global smartphone shipments in 2026, while rising memory and component costs have pushed manufacturers to raise prices and manage product volumes more carefully. 3

Separate industry reporting said China’s smartphone shipments fell 4.3% year over year to 66 million units in the second quarter, with rising memory and component costs contributing to price increases. Xiaomi’s second-quarter shipments fell 21.7%, according to IDC figures cited by Reuters.

Against that backdrop, Xiaomi’s reported first-half figures point to a shift toward higher-priced devices. The company sold 65 million handsets in the first half of 2026 at an average price of 1,329 yuan, compared with 84 million at 1,141 yuan in the first half of 2025 and 83 million at 1,123 yuan in the first half of 2024. 3

An in-house chip cannot remove memory shortages or weak consumer demand. Its strategic value is longer term: Xiaomi can potentially decide more of its product roadmap itself, tailor premium devices more closely and reduce reliance on external chip vendors as competition intensifies.

The O3 is part of a wider Xring roadmap

Xiaomi also said it had contracted TSMC to produce two additional chips:

• Xring O100: a 6-nanometre neural-processing unit designed to run or support Xiaomi’s MiMo large language model across consumer electronics.
• Xring D100: a 3-nanometre processor intended for autonomous-driving applications.

Xiaomi said the O100 and D100 had completed development and were targeted for deployment in 2027. 3

Together, the three chips indicate that Xiaomi’s silicon program is not limited to smartphones. The company is positioning the Xring family across connected devices, AI-enabled consumer hardware and vehicles, while using TSMC as its manufacturing partner.

What is confirmed—and what is not

The confirmed part of the announcement is Xiaomi’s introduction of the Xring O3 and its broader disclosure about the O100 and D100 roadmap. The 3-nanometre manufacturing process for the O3, its expected use in an upcoming flagship foldable and the 200,000–300,000-unit shipment target came from sources familiar with the matter. Xiaomi and TSMC had not immediately confirmed those specific details. 3

That distinction matters. The O3 signals a meaningful step toward Xiaomi’s own chip platform, but its eventual performance, availability and impact on Xiaomi’s supplier mix will depend on the final product and shipment scale—not just the process technology or the processor’s name.
