REDMI’s next performance beast is already creating serious hype online. On February 5th, well-known tech blogger Digital Idle Talk Station shared new details about an engineering prototype described as a “sub-series D9500 dual-core performance phone.” The leak quickly caught attention because the device reportedly includes premium flagship features like an X-axis linear motor (0815±), symmetric dual speakers with tuned sound, a 3D ultrasonic fingerprint scanner, and top-grade IP68/IP69 dust and water resistance.
As expected, netizens are now strongly guessing this mystery device is the upcoming REDMI K90 Ultra. And honestly, the speculation makes sense. Previous leaks already hinted that the K90 Ultra is set to deliver top-level performance, likely powered by the upcoming MediaTek Dimensity 9500 chipset. If true, this would instantly make it one of the most powerful Redmi phones ever built.
What makes the leak even more exciting is the rumor that Redmi may add an active cooling fan to the phone. One tipster suggested the brand could place a micro-fan inside the camera module (DECO), which would help control heat during heavy gaming while still maintaining IP68-level protection. If Redmi pulls this off, it could be a major advantage over competitors in the same segment.

Display details also sound impressive. The REDMI K90 Ultra is expected to feature a large 6.8-inch flat screen with 1.5K resolution and a super-smooth 165Hz refresh rate, which is perfect for gamers and power users who want ultra-fast responsiveness and fluid visuals.
Battery life could be another big highlight. Early leaks suggest the phone may come with a massive 8500mAh battery, along with 100W wired fast charging. If this turns out to be accurate, the K90 Ultra could easily become one of the strongest battery performers in the premium performance category.
The “Ultra” editions in Redmi’s K-series have always been known for raw power, and the K80 Ultra already received strong user reviews in the market. Pricing will be a key factor again. For reference, the K80 Ultra’s 12GB + 256GB variant launched at 2599 RMB, which is approximately $360 USD. If Redmi keeps a similar price point while adding upgrades like the Dimensity 9500 and active cooling, the REDMI K90 Ultra could become one of the most competitive performance smartphones of the year.
