Xiaomi is reportedly developing two new smartphones, and the Redmi K90 Ultra is shaping up to be the standout model for power users and mobile gamers. A fresh leak from well-known tipster Digital Chat Station now claims to reveal the phone’s core specifications, painting a picture of a device built to compete with dedicated gaming phones rather than typical flagship rivals.
One of the biggest highlights is said to be a 1.5K LTPS display paired with a super-smooth 165Hz refresh rate. A screen this fast can noticeably improve responsiveness in competitive titles, making actions feel more immediate and gameplay look cleaner during fast motion. If this spec turns out to be accurate, the Redmi K90 Ultra could appeal to gamers who specifically prioritize high refresh rates and consistent frame delivery.
Under the hood, the leak points to the MediaTek Dimensity 9500, expected to be MediaTek’s top-tier chipset for the generation. While it may not be positioned as the absolute best option for every gaming and emulation scenario compared to the most expensive Snapdragon alternatives, it’s still described as a high-performance chip with enough headroom to target high frame rates in popular mainstream games—potentially reaching 165 FPS with the right software tuning and game support.
To keep performance stable over long sessions, the Redmi K90 Ultra is also rumored to include an active cooling fan inside the phone. That’s a feature usually reserved for gaming-focused devices, and it suggests Xiaomi is serious about sustained performance. Active cooling can help reduce heat buildup during extended matches or graphically demanding games, lowering the chance of throttling that can lead to sudden frame drops.
Battery life could be another major selling point. According to the leak, the Redmi K90 Ultra may pack a battery exceeding 8,000mAh, which would be a huge capacity for a modern smartphone and a clear advantage for long gaming sessions, travel, or heavy daily use.
Audio is also getting attention. The device is said to feature custom-tuned symmetrical dual speakers, and earlier chatter pointed to Bose-tuned sound. If accurate, this could translate into louder, clearer stereo output with better balance—useful for gaming, streaming, and music without needing earbuds.
Additional leaked features round out a spec sheet that sounds decidedly “ultra”: an ultrasonic fingerprint sensor, an IP68 rating for dust and water resistance, a dedicated graphics chip designed to enhance gaming performance, and a large vibration motor for stronger, more precise haptic feedback. Together, these upgrades would position the Redmi K90 Ultra as a meaningful step up from the previous generation, especially for users who want flagship power with gaming-first features.
As for timing, there’s no official release date yet, but current expectations point to a China launch in April 2026. If these specifications hold true, the Redmi K90 Ultra could be one of the most interesting gaming-ready flagships of 2026, targeting high refresh rate fans, performance enthusiasts, and anyone who values long battery life in a premium phone.
