Redmi K90 Ultra tipped to pack Dimensity 9500, 8,500mAh battery, and built-in cooling

Redmi is preparing to expand its K90 lineup with an Ultra variant that promises flagship-level specifications, according to a fresh leak from tipster Digital Chat Station. The upcoming Redmi K90 Ultra is shaping up to be a powerhouse device that could challenge premium offerings in the Android ecosystem.

At the heart of the device will be MediaTek's latest flagship chipset, the Dimensity 9500 SoC. This represents a strategic shift for Redmi, as the recently launched K90 Pro Max opted for Qualcomm's Snapdragon 8 Elite Gen 5. The choice of MediaTek's silicon suggests Redmi is betting on the Dimensity 9500's performance and efficiency to deliver competitive flagship experiences at potentially more accessible price points.

The battery specifications are particularly noteworthy. The K90 Ultra is rumored to pack an 8,500mAh battery, which would be one of the largest capacities in a mainstream flagship smartphone. Even more impressive, Redmi is reportedly attempting to fit an even larger cell into the device's chassis. This massive battery, combined with 100W wired fast charging support, should provide exceptional endurance and quick top-ups for power users.

A standout feature that sets the K90 Ultra apart from typical flagship designs is the inclusion of a built-in fan for active cooling. This cooling solution, paired with the high-performance Dimensity 9500, suggests Redmi is targeting sustained performance during intensive gaming sessions or demanding workloads. The fan system could help maintain peak CPU and GPU clock speeds for longer periods without thermal throttling.

On the display front, the device is expected to feature a 6.8-inch panel with 165Hz refresh rate and 1.5K resolution. This high-refresh-rate display should deliver smooth scrolling and responsive touch interactions, while the 1.5K resolution (likely 1220 x 2712 pixels) offers a good balance between sharpness and power efficiency. The phone will also include an ultrasonic in-display fingerprint scanner for secure biometric authentication.

Build quality appears to be a priority as well, with the K90 Ultra reportedly featuring a metal frame construction. This should provide a premium feel and improved durability compared to plastic alternatives.

The Redmi K90 Ultra's specifications paint a picture of a device designed for users who demand top-tier performance without compromise. The combination of MediaTek's latest chipset, massive battery capacity, active cooling, and high-refresh-rate display positions it as a compelling option in the competitive flagship smartphone segment.

While an official launch timeline remains unknown, the detailed specifications revealed in this leak suggest the device is in advanced development stages. Given Redmi's typical product cadence, we might expect to see the K90 Ultra debut in the coming months, potentially alongside other devices in the K90 family.

For context, the K90 Pro Max launched with the Snapdragon 8 Elite Gen 5, a 6.67-inch 2K display with 120Hz refresh rate, and a 5,000mAh battery with 120W charging. The Ultra variant clearly takes a different approach with MediaTek silicon, significantly larger battery, and enhanced cooling capabilities.

The Redmi K90 Ultra represents an interesting strategic move in the Android flagship market. By offering a MediaTek-powered alternative with unique features like active cooling and exceptional battery life, Redmi appears to be targeting a specific segment of power users who prioritize sustained performance and battery endurance over other considerations. As more details emerge, it will be fascinating to see how this device positions itself against competitors from OnePlus, iQOO, and other performance-focused brands in the Android ecosystem.
