Xiaomi 15S Pro: The Powerful Return of Self-Developed Chips and UWB Technology, Ushering in a New Era for Xiaomi's High-End Flagships

As Xiaomi celebrates its 15th anniversary, co-founder Lin Bin officially confirmed the existence of the Xiaomi 15S Pro. This marks the long-awaited return of the Xiaomi S-series flagship after nearly three years and signifies a significant breakthrough in Xiaomi's technological innovation. This highly anticipated flagship phone not only fulfills the long-held expectations of Xiaomi users but also showcases Xiaomi's ambition in self-developed SoCs, UWB ecosystem collaboration, and cross-device connectivity a complete internal and external revolution is brewing.

Following the success of the Xiaomi 12S Ultra, which solidified its position in the high-end market with its Leica imaging and Snapdragon 8+ Gen 1 combination, the S-series has become Xiaomi's testing ground for cutting-edge technologies. Unlike the annual iterations of the standard numbered series, the S-series typically employs a "half-generation upgrade" strategy, focusing on breakthrough technological innovations in a specific area while upgrading core hardware. The Xiaomi 12S Ultra introduced the 1-inch large-sensor and Leica color science; the Xiaomi 15S Pro expands this mission further, not only continuing its imaging advantages but also realizing the commercial application of its self-developed chip and addressing key shortcomings in its smart ecosystem.

The most significant highlight of the Xiaomi 15S Pro is undoubtedly its self-developed chip. Market reports suggest this chip is based on TSMC's N4P process, utilizing an octa-core three-cluster architecture (1+3+4), offering comparable overall performance to the Snapdragon 8 Gen 2.5. While initially targeting the mid-to-high-end market, the strategic significance of this self-developed chip is undeniable. From the Surge C1 imaging chip and Surge P1 fast-charging chip to this integrated SoC attempt, Xiaomi is steadily building its robust chip design capabilities. The choice of the N4P process (TSMC's enhanced 5nm) reflects Xiaomi's pragmatic technological approach, ensuring a balance between energy efficiency and cost-effectiveness while avoiding the high risks and costs associated with 3nm processes.

More importantly, this self-developed SoC can deeply optimize the low-level scheduling mechanism of the MIUI OS, particularly in scenarios involving connectivity with the Xiaomi SU7 smart car. Chip-level optimization will significantly improve the response speed of features such as UWB positioning and digital keys. Against the backdrop of high Snapdragon 8-series chip prices, the large-scale application of this self-developed chip will effectively reduce hardware costs, potentially lowering the prices of future high-end models. Furthermore, the inclusion of customized NPU and ISP modules contributes to differentiated imaging and AI capabilities, laying a solid foundation for Xiaomi's future development. However, the ultimate performance of this self-developed chip is closely related to the optimization level of the MIUI OS. Good system optimization will maximize the chip's performance advantages, while poor optimization could lead to performance limitations or even prevent it from reaching its full potential. Further observation and verification are therefore necessary.

Beyond the self-developed SoC, the Xiaomi 15S Pro is expected to offer many other surprises. Based on current leaks, it will inherit the design language of the Xiaomi 15 Pro, featuring a 2K resolution fully symmetrical micro-curved screen. This aims to maintain the immersive visual experience of a curved screen while mitigating mis-touches through the symmetrical design. It will also support a 120Hz refresh rate, high-frequency eye protection PWM dimming, and ultrasonic fingerprint unlocking. The rear Leica triple-camera module will likely retain the "big-eyed cute" design, with minimal anticipated changes to the lens specifications.

In terms of battery life, the Xiaomi 15S Pro will house a 6000mAh+ ultra-large capacity silicon-carbon anode battery, paired with 90W wired fast charging and 50W wireless fast charging. In addition to inheriting many advantages of the Xiaomi 15 Pro, the Xiaomi 15S Pro introduces new selling points. If the self-developed SoC is the "inner strength" of the Xiaomi 15S Pro, then the return of UWB (Ultra-Wideband) technology is its "connecting meridian." UWB debuted in the Xiaomi MIX 4 in 2021 with its "one-touch connection" feature, allowing users to quickly control smart devices by precisely pointing their phone. However, due to limited ecosystem maturity at the time, this technology was absent in subsequent models. The return of UWB technology is clearly deeply linked to Xiaomi's automotive strategy.

Combined with the Xiaomi SU7 smart car, UWB enables keyless entry, precise car location, and synchronization of personalized in-car settings. It also has the potential to become a central hub for smart homes, building a new paradigm for cross-device collaboration. The numerous highlights of the Xiaomi 15S Pro, including the commercialization of its self-developed SoC, the scene-based application of UWB technology, and the balance between ultra-large battery and fast charging, give it strong market impact.

The unveiling of the Xiaomi 15S Pro is more than just a new phone launch; it represents a significant step forward in Xiaomi's journey of technological innovation. It embodies years of technological accumulation and innovation, representing Xiaomi's new posture in the high-end flagship market. The successful commercialization of its self-developed SoC will further enhance Xiaomi's influence in the mobile phone industry chain and provide strong impetus for its future development. The return of UWB technology signifies Xiaomi's determination and confidence in building a comprehensively interconnected ecosystem. The phone's ultimate performance will undoubtedly serve as a critical benchmark for Xiaomi's technological strength and innovative capabilities. Through the Xiaomi 15S Pro, we see Xiaomi's ambition and strength in the high-end market, as well as its unwavering commitment to technological innovation. Whether Xiaomi can stand out in the fiercely competitive market with this flagship phone remains to be seen. The success or failure of the Xiaomi 15S Pro will also have a profound impact on the entire mobile phone industry, providing valuable experience and reference for other manufacturers in the application of self-developed chips and UWB technology.

In conclusion, the launch of the Xiaomi 15S Pro is a significant milestone in Xiaomi's development, representing a breakthrough in the high-end flagship market and signaling Xiaomi's continued commitment to technological innovation, bringing more surprises and expectations for users. The success or failure of this phone is not only related to Xiaomi's own development but will also have a profound impact on the entire mobile phone industry. The technological innovation and product highlights of the Xiaomi 15S Pro alone are enough to make it one of the most anticipated flagship phones of the second half of 2023. Let us look forward to the official launch of the Xiaomi 15S Pro and witness Xiaomi's new chapter in the high-end market.
