The latest leaks surrounding the upcoming Redmi K90 Ultra suggest a major leap forward in mobile technology, especially for gamers and power users. The new device is shaping up to be more than just an incremental update; it represents a significant shift in Xiaomi’s engineering philosophy. With groundbreaking features previously unseen in a mainstream Redmi phone, the K90 Ultra is poised to shake up the market.
Redmi K90 Ultra Specs: A Paradigm Shift for Gaming
The most talked-about feature is undoubtedly the inclusion of a built-in active cooling fan. This technology, typically reserved for niche gaming phones, is being integrated into a Redmi device for the first time. This hardware solution aims to provide sustained peak performance from the powerful MediaTek Dimensity 9500 chipset, preventing thermal throttling during intense gaming sessions. It seems Xiaomi is moving beyond software optimizations to create a true hardware beast.
Furthermore, the device is set to push the boundaries of battery life and display technology. Leaks indicate the Redmi K90 Ultra will be equipped with a colossal 8,500 mAh battery, a capacity that dwarfs the 5,000-6,000 mAh standard in today’s flagships. This promises multi-day usage on a single charge. To complement this, 100W fast charging support will ensure the massive battery can be refilled quickly, minimizing downtime for users.

On the front, users will be treated to a 6.8-inch 1.5K resolution OLED panel with an ultra-smooth 165Hz refresh rate. This is an upgrade from its predecessor’s 144Hz screen, offering a tangible advantage in competitive mobile games where every millisecond counts.
Early Launch Date and Premium Design
Redmi also appears to be adjusting its launch schedule. The device, identified by the model number 2604FRK1EC in the GSMA IMEI database, is expected to launch in April 2026. The “2604” in the model number points to this earlier window, a strategic move to get ahead of competitors. This is about two months earlier than the typical June or July release for Redmi’s “Ultra” models.
In terms of design, the K90 Ultra is expected to feature premium materials, including a metal frame and more rounded corners for better ergonomics. Other high-end features like an ultrasonic in-display fingerprint scanner and an IP68 rating for water and dust resistance are also anticipated. Following its debut in China, the device is expected to launch globally as the Xiaomi 17T Pro. However, it remains uncertain whether the global version will retain the physical cooling fan.
