With the relentless advancement of smartphone technology, Xiaomi, a leading domestic mobile phone brand, continues to drive independent innovation. Recently, whispers about Xiaomi's upcoming 15S Pro have garnered significant attention in the tech community. As a monumental phone celebrating Xiaomi's 15th anniversary, it not only heralds the debut of Xiaomi's self-developed Xuanjie O1 chip but also introduces comprehensive upgrades across imaging systems, screen displays, battery life, and more. Let's explore the highlights of this flagship phone, set to officially unveil on May 22.

The most striking aspect is that the Xiaomi 15S Pro will be the first to feature Xiaomi's self-developed Xuanjie O1 chip. According to reliable sources, this chip leverages an advanced 3nm process technology, marking Xiaomi's formal entry into the realm of high-end self-developed chips. Lei Jun himself announced on social media that the Xuanjie O1 chip has commenced mass production, a significant milestone in Xiaomi's chip independent research and development journey. While specific chip architecture details remain under wraps, leaks suggest a 1+3+4 CPU design, comprising a single X4 super core, three A720 large cores, and four A520 small cores, promising impressive performance.

In terms of design, the Xiaomi 15S Pro inherits the refined aesthetics of the Xiaomi 15 Pro, sporting a metal frame with a four-curved wrap design, presenting a sleek "four equal-width sides" look. The seamless glass sandwich structure and flat metal frame offer a cohesive visual experience. The display boasts a 6.73-inch 2K resolution full-depth four-curved screen, supported by LTPO adaptive refresh rate technology, enhancing visual immersion while balancing battery life and display performance.

Imaging has always been a cornerstone of Xiaomi's flagship phones, and the Xiaomi 15S Pro does not disappoint. Leaks indicate that the phone will continue to sport a Leica-certified imaging system with a triple rear camera setup, including a 50-megapixel main camera, coupled with ultra-wide-angle and telephoto lenses to cater to diverse shooting scenarios. Leica's color science and professional filter modes promise an enhanced photography experience. Notably, the Xiaomi 15S Pro has secured radio approval from the Ministry of Industry and Information Technology and supports ultra-wideband (UWB) radio transmission, enabling precise indoor positioning and device interconnectivity.

Battery life sees a significant leap with the Xiaomi 15S Pro, expected to carry a battery capacity exceeding 6000mAh, with rumors hinting at an internal target of 7000mAh or more, significantly alleviating battery anxiety. Charging capabilities are equally impressive, with the phone passing 3C certification and supporting 90W wired fast charging while retaining wireless charging options, balancing speed and convenience. This high-capacity battery, coupled with efficient charging technology, ensures even heavy users can navigate through a full day seamlessly.

As Xiaomi's 15th-anniversary masterpiece, the Xiaomi 15S Pro embodies more than just a hardware upgrade; it reflects Xiaomi's profound commitment to technological innovation and user experience. Pioneering the Xuanjie O1 chip signifies Xiaomi's fortified hardware integration and system optimization capabilities. The evolving Leica imaging system underscores Xiaomi's unwavering pursuit of professional photography excellence. The synergy of a battery over 6000mAh and 90W fast charging directly addresses daily user pain points.

The Xiaomi 15S Pro launch will coincide with other significant Xiaomi ecosystem products.
