Xiaomi has officially introduced its first smartphone that’s equipped with its own first-party chipset in China. Known as the Xiaomi 15S Pro, it is basically a new variant of the current generation flagship’s Pro model, which comes with the brand’s own Xring O1 instead of a Snapdragon 8 Elite.
Developed and designed by Xiaomi and fabbed on TSMC’s second-generation N3E 3nm process, the first-party Xring O1 chipset features a ten-core CPU cluster with 2x Cortex-X925 prime cores clocked @ 3.9GHz, 6x Cortex-A725 performance cores between 1.9-3.4 GHz and 2x Cortex-A520 efficiency cores @ 1.8 GHz. The CPU is joined by a 16-core ARM Immortalis-G925 GPU and a 6-core NPU rated at 44 TOPS.
Performance-wise, Xiaomi revealed that its flagship SoC scored over 3 million points on the AnTuTu benchmarking platform, edging out the Snapdragon 8 Elite. Xring O1 also managed over 3,000 single core points and 9,000 multi-core points in Geekbench 6, with the multi-core score edging out Apple’s A18 Pro.
Alongside the chipset, the Xiaomi 15S Pro comes with 16GB of LPDDR5T RAM, up to 1TB of UFS 4.1 storage, USB 3.2 Gen2 connectivity, Wi-Fi 7, and a custom 3-core Xiaomi ISP. Out of the box, the 15S Pro comes with Xiaomi HyperOS 2, which is based on Android 15.

Outside of the chipset swap, the rest of the specs are identical to those of the China-only Xiaomi 15 Pro model. These include a 6.73-inch LTPO AMOLED (QHD+ 120Hz), three 50MP cameras (ultrawide, wide and a 5x periscope) and a 6,100mAh silicon carbon battery with 90W wired charging.
The 16/512GB trim starts at CNY5,499 (~RM3,263), while the 1TB option is priced at CNY5,999 (~RM3,560). In terms of colour options, the phone is offered in either Black or Blue. For now, the new Xiaomi 15S Pro is only available in China, with no international launch plans planned just yet.
