May 24, 2025 – Beijing, China — Xiaomi has officially launched its flagship smartphone, the Xiaomi 15S Pro, marking a bold move toward chip independence with its self-developed Xring O1 processor.
This launch represents a major milestone in Xiaomi’s long-term strategy to compete head-on with Apple and Qualcomm in both performance and innovation.
Xring O1: Xiaomi’s First In-House Chipset
At the heart of the Xiaomi 15S Pro is the Xring O1, a powerful 10-core processor fabricated on TSMC’s 3nm process. The chip includes:
- 2 high-performance cores (up to 3.9GHz)
- 16-core Immortalis-G925 GPU
- 6-core NPU with up to 44 TOPS AI computing power
Early performance benchmarks suggest the device exceeds 3 million points on AnTuTu V10, making it one of the most powerful smartphones of 2025, rivaling the Snapdragon 8 Gen 4 and Apple A18 Pro.
Display and Design
The Xiaomi 15S Pro features:
- 6.73-inch QHD+ LTPO AMOLED display
- 120Hz adaptive refresh rate
- 3200 nits peak brightness
- Gorilla Glass Victus 2 protection
With a premium build and IP68 water/dust resistance, it’s available in Carbon Black and Ocean Blue, with a sleek matte finish.
Professional Leica Camera System
Co-engineered with Leica, the triple camera setup includes:
- 50MP main wide sensor (Leica Summilux)
- 50MP ultra-wide lens
- 50MP periscope telephoto (up to 5x optical zoom)
- 32MP front camera for high-quality selfies and video calls
The phone supports 4K Dolby Vision and RAW HDR photography, catering to content creators and photography pros.
Battery and Charging
The device is powered by a 6,100mAh second-gen silicon-carbon battery, featuring:
- 90W wired turbo charging
- 50W wireless charging
- 10W reverse wireless charging
Xiaomi claims a full charge in under 28 minutes wired and 45 minutes wirelessly.
Software and Ecosystem
The 15S Pro ships with Xiaomi HyperOS 2.0, based on Android 15, optimized for smoother animations, better battery management, and tighter integration with Xiaomi’s ecosystem of AIoT devices, tablets, and smart homes.
Pricing and Availability
The Xiaomi 15S Pro is currently available in China, with international launch dates yet to be announced. Two variants are offered:
- 16GB RAM + 512GB storage – ¥5,499 (~$763 USD)
- 16GB RAM + 1TB storage – ¥5,999 (~$833 USD)
Global tech enthusiasts can access the phone via importers, though official global pricing and availability are still pending.
Xiaomi’s Bold Future in Chip Design
Xiaomi’s unveiling of the Xring O1 isn’t just about performance — it’s a strategic declaration. The company has committed to investing over $7 billion in chip development over the next decade, aligning with China’s push for semiconductor self-reliance. By moving away from third-party chipmakers like Qualcomm and MediaTek, Xiaomi hopes to gain tighter control over hardware-software optimization and long-term innovation.
