Xiaomi Launches 18 Fold in China With First In-House Flagship Chip
The new foldable challenges Samsung's dominance with a proprietary XRing O3 processor and a massive 6,000mAh battery.
Xiaomi has officially launched the Xiaomi 18 Fold in China, marking a significant pivot in the company's hardware strategy. Following its initial debut at IFA 2026, the device is now available for purchase starting at ¥10,999, with a premium limited-edition ceramic version priced at ¥15,999.
The device's most critical upgrade is the inclusion of the XRing O3, Xiaomi's first in-house processor used in a flagship smartphone. Beyond the silicon, the 18 Fold emphasizes endurance and portability; it features a 6,000mAh battery that supports 67W wired and 50W wireless charging. Physically, the handset weighs 219 grams and measures 10.68mm in thickness when folded.
A Strategic Shift in Silicon
For years, Xiaomi relied on Qualcomm and MediaTek for its high-end processing needs. The transition to the XRing O3 signals an ambition to control the entire hardware stack, a vertical integration strategy similar to the one employed by Apple. By designing its own silicon, Xiaomi can more tightly optimize the interaction between its software and hardware, potentially increasing efficiency and performance in the demanding foldable category.
Challenging the Industry Standard
Xiaomi is positioning the 18 Fold as a direct hardware alternative to the Samsung Galaxy Z Fold 8. The most visible point of contention is battery life. While the Galaxy Z Fold 8 carries a 4,800mAh battery, Xiaomi's 6,000mAh cell offers a substantial increase in capacity, addressing one of the most persistent complaints regarding foldable devices. This aggressive approach to specifications suggests Xiaomi is no longer content with following the industry lead set by Samsung, but instead aims to outpace it in raw utility.
The Foldable Landscape
The 18 Fold enters a crowded and intensifying market. It currently competes with the Galaxy Z Fold 8 and the Huawei Pura X Max, while the industry continues to anticipate a rumored foldable entry from Apple, often referred to as the 'iPhone Ultra.' As Xiaomi moves toward proprietary chips and larger batteries, the focus of the foldable war is shifting from the mere novelty of the folding screen to the fundamental performance and longevity of the device. Whether the XRing O3 can compete with established mobile platforms remains the primary question for the coming year.
