Xiaomi Debuts TSMC-Manufactured Xring O3 Processor in Foldable Phone Battle with Huawei

Key Highlights

• Xiaomi introduced the Xring O3, its latest proprietary smartphone processor, manufactured using TSMC’s advanced 3nm process technology
• The processor will drive Xiaomi’s next premium foldable smartphone, with production goals set between 200,000 and 300,000 devices
• Two additional Xiaomi-designed chips are in TSMC’s pipeline: the Xring O100 neural processor for artificial intelligence and the Xring D100 for self-driving capabilities
• The smartphone industry faces a projected 14% decline in worldwide shipments during 2026
• Xiaomi’s handset sales dropped to 65 million units in H1 2026, compared to 84 million in the corresponding 2025 period

On Monday, Xiaomi revealed its latest Xring O3 smartphone processor, with manufacturing handled by Taiwan Semiconductor Manufacturing Company leveraging 3-nanometre fabrication technology. This announcement represents the company’s second proprietary chip following the Xring O1’s debut in May 2025.

The O3 processor is slated to become the engine behind Xiaomi’s forthcoming premium foldable smartphone. Industry sources with knowledge of the company’s strategy indicate Xiaomi has established shipment objectives ranging from 200,000 to 300,000 units for this particular model.

Foldable smartphones represent the premium segment of the mobile market. By entering this category, Xiaomi directly challenges Huawei, which dominated China’s foldable phone sector with a commanding 68% market share during Q2, delivering 1.6 million units to customers.

Neither Xiaomi nor TSMC provided official statements regarding the chip’s production partner, manufacturing process details, or shipment projections when contacted. The sources providing this information requested anonymity due to the confidential nature of these strategic plans.

Broadening the Silicon Portfolio

Monday’s reveal encompassed more than the O3 alone. Xiaomi disclosed that it has engaged TSMC to manufacture the Xring O100, a 6-nanometre neural processing unit engineered to execute its MiMo large language model directly on end-user devices.

Additionally, a third processor called the Xring D100 emerged—a 3-nanometre chip developed specifically for autonomous vehicle applications. According to Xiaomi, the O3 has already entered volume manufacturing, whereas the O100 and D100 have completed their development phases and are scheduled for market introduction in the following year.

The Xring O1, representing Xiaomi’s inaugural proprietary chip, found its way into smartphones, tablets, and smartwatches. During last week’s earnings presentation, the company reported that total shipments of O1-equipped devices surpassed the one million milestone since introduction. Approximately 150,000 smartphones incorporating the processor have reached consumers since May 2025.

Market Contraction and Cost Pressures

Xiaomi’s strategic chip development initiative unfolds against challenging market conditions. The manufacturer delivered 65 million mobile phones during the first six months of 2026 with an average selling price of 1,329 yuan, representing a significant decrease from 84 million units priced at 1,141 yuan during the comparable 2025 timeframe.

Industry analysts at International Data Corporation project global smartphone shipments will contract by 14% throughout 2026. Escalating costs for memory modules and other essential components have driven device prices upward, subsequently dampening consumer purchasing activity.

Through in-house chip development, Xiaomi mirrors strategies previously adopted by Apple, Samsung, and Huawei. Manufacturers exercising greater control over their component supply chains achieve cost reductions and enhanced product differentiation compared to competitors relying exclusively on standardized processors from suppliers like Qualcomm and MediaTek.

The Xring O3’s introduction provides the most definitive evidence to date of Xiaomi’s dedication to establishing a comprehensive proprietary chip development roadmap spanning smartphones, artificial intelligence applications, and automotive technologies in the years ahead.
