It has been rumored for months that Xiaomi is preparing for the premiere of the flagship smartphone Xiaomi 15S Pro, which will be built on a processor of the company’s own design (details), and now additional information has appeared about this.
To be more precise, yesterday, April 6, the day of Xiaomi’s 15th anniversary, the company’s executives, including founder Lei Jun and co-founder Lin Bing, took to social media to celebrate the event.
In a remarkable conversation with fans, Lin Bing casually confirmed the existence of the upcoming Xiaomi 15S Pro smartphone. This is the first time the model has been officially recognized, although no promotional materials have been provided so far.

The Xiaomi 15S Pro will be the brand’s first flagship S-series since the Xiaomi 12S, which was released almost three years ago. According to the leaks, it retains the main design elements of the Xiaomi 15 Pro, including a 2K display curved on four sides and a triple Leica camera.
The main improvement is the battery, which is expected to have a capacity of more than 6,000 mAh. In addition, the smartphone will support fast charging up to 90 watts.
In addition, Xiaomi 15S Pro may debut with its own chipset based on TSMC’s N4P process technology – the new chip uses a standard three-cluster eight-core layout.
A well-known Digital Chat Station insider also spoke about the key specifications of the future Xiaomi processor – one Arm Cortex X925 super core with a frequency of 3.2 GHz, three Cortex A725 cores with a frequency of 2.6 GHz and four energy-efficient Cortex A520 cores operating at a frequency of 2.0 GHz.

The Imagination Technologies IMG DXT72 graphics chip with a clock frequency of 1.3 GHz will be responsible for the graphics. Preliminary estimates indicate that it can outperform the Adreno 740 in the Snapdragon 8 Gen 2, offering significant graphics potential.
