A prominent tipster on Weibo, Smart Pikachu, has just dropped a massive leak detailing the future of Xiaomi’s sub-brand and parent-line flagship killers. Slated for an April 2026 release exclusively in China, the upcoming REDMI K90 Ultra is shaping up to be an absolute powerhouse designed specifically for extreme performance.
For our international readers, it is crucial to note that while the REDMI K90 Ultra is a China-exclusive model, it will heavily influence—and ultimately launch globally as—the Xiaomi 17T Pro, albeit with potential camera and battery optimizations tailored for the global market.
According to the leak, Xiaomi is preparing two Dimensity 9500-powered smartphones to appeal to different market segments: a sub-brand device focused entirely on unthrottled performance (the REDMI K90 Ultra) and a “parent line” device expected to be the upcoming Xiaomi CIVI 6, which will prioritize imaging and design.
Core Content: Pushing Hardware Boundaries
The engineering choices for the REDMI K90 Ultra indicate a complete pivot toward competitive mobile gamers and power users. Here is the technical breakdown of what is driving this device:
-
Processor & Extreme Thermal Management: The device is powered by MediaTek’s flagship Dimensity 9500 chipset. To tame this silicon, Xiaomi is making a highly unusual but welcome engineering choice: the inclusion of a physical active cooling fan. This hardware addition is specifically engineered to eliminate thermal throttling, ensuring sustained peak clock speeds during heavy, prolonged gaming sessions.
-
Esports-Grade Display: Edge distortion is a massive pain point for competitive gamers. To combat this, the K90 Ultra features a 165Hz 1.5K flat display, prioritizing precision touch sampling and visual fluidity over curved aesthetics.
-
Unprecedented Endurance: In a massive leap for smartphone longevity, Xiaomi has managed to pack an 8000 mAh battery into the chassis.
-
Premium Additions: Moving away from optical sensors, the device will utilize an ultrasonic under-display fingerprint sensor for faster, more secure biometric unlocks even with wet hands. It also retains an IP68 rating for total dust and water resistance.
-
Camera Capabilities: While the parent line (Xiaomi Civi 6) will focus heavily on imaging aesthetics, the K90 Ultra isn’t slouching. It is expected to feature a massive 200 MP primary camera to deliver high-resolution pixel-binned photography, making it a well-rounded device despite its gaming focus.

Market Impact and Pricing Realities
The REDMI K90 Ultra is officially targeting a domestic launch in China this April 2026. Because of this, initial pricing will be strictly in Chinese Yuan (CNY). However, industry insiders warn that consumers should brace for a higher price tag than previous generations. Due to the ongoing global chip crisis impacting silicon yields and fabrication costs, the introductory pricing—and its eventual USD ($) equivalent—will reflect these supply chain constraints.
Despite the expected price hike, the inclusion of an active fan, a 200MP sensor, and an 8000mAh battery represents incredible raw value. International fans should keep a close eye on this release, as these exact hardware specs lay the direct foundation for the highly anticipated Xiaomi 17T series hitting the global market later in the year.
