Now that the Xiaomi 15 series launch is over—both globally and in China—the company is already focusing on the next release: the Xiaomi 15S series. The new lineup is expected to debut in China within the next few months. However, it might not reach international markets under the same name. Meanwhile, a fresh leak has revealed some key specs of the upcoming device.
Xiaomi 15S Pro key specifications leaked
An upcoming mysterious Xiaomi smartphone with the model number 25042PN24C has been listed on China’s 3C certification website. Even though the website does not revel the exact moniker of the smartphone, the device is most likely the Xiaomi 15S Pro.

According to a certification website, the Xiaomi 15S Pro will support up to 90W fast wired charging and, as expected, 5G connectivity. But the more interesting reveals are its satellite network support and UWB (Ultra-Wideband) technology.
UWB tech is a short-range wireless communication feature that enables highly precise location tracking. In smartphones, it can improve device pairing, smart home control, and even digital car key functionality. For example, you could unlock your car just by walking up to it or point your phone at a smart device to control it instantly—no manual connection needed. This makes UWB a handy upgrade for seamless, fast, and secure interactions between devices.
