Early details point to the Redmi K90 Ultra, with emphasis on sustained performance, battery life, and display upgrades, hinting at a notable shift in Redmiβs flagship strategy this year.
Redmi K90 Ultra key details tipped

According to information shared by tipster Digital Chat Station, the Redmi K90 Ultra is expected to be powered by the Dimensity 9500 chipset. Previous iterations of K-series Ultra phones have featured βPlusβ versions of Dimensity 9-series chipsets, such as the Dimensity 9400+, Dimensity 9300+, and Dimensity 9200+. Recent reports reveal that this time MediaTek has no plans to launch the Dimensity 9500+, which was expected to be an overclocked version of the existing Dimensity 9500.
What makes the Redmi K90 Ultra stand out is the reported inclusion of an internal cooling fan. This would make it the first Xiaomi group smartphone to feature active cooling, aimed at maintaining stable performance during extended gaming sessions. The cooling system is expected to allow the chipset to run closer to its peak capabilities without thermal throttling.
The Redmi K90 Ultra is tipped to pack an 8,500mAh battery, with internal testing reportedly ongoing to push the capacity even higher. Fast charging support is said to reach 100W via wired charging, with possible compatibility with high-power PPS standards.
The display is expected to be a large flat panel measuring around 6.8 inches, offering 1.5K resolution and a refresh rate that could go as high as 165Hz. With more games now supporting higher refresh rates, this setup should deliver a smoother experience. Other anticipated features include a metal frame, an ultrasonic in-display fingerprint sensor, and full water resistance.
The Redmi K90 Ultra may launch in May or June this year. The brand is also expected to unveil the Redmi K Pad 2, a performance-focused tablet, alongside it.
