REDMI may be preparing an unconventional approach for its next high-end smartphone. Instead of relying solely on the latest flagship chipset, the upcoming REDMI K90 Ultra is rumored to combine proven flagship hardware with active cooling technology in an effort to compete with significantly more expensive devices.
According to a new leak from well-known tipster Digital Chat Station on Weibo, REDMI’s strategy centers on maximizing sustained performance rather than simply chasing the newest processor.

The leak claims that the REDMI K90 Ultra will be powered by Qualcomm’s Snapdragon 8 Elite chipset rather than the newer Snapdragon 8 Elite Gen 5 found in upcoming flagship smartphones.
On paper, that might sound like a disadvantage. However, REDMI reportedly plans to pair the chipset with an active cooling fan, a feature rarely seen outside gaming-focused smartphones.
The addition of a built-in fan is said to help maintain performance during extended gaming sessions and demanding workloads by keeping temperatures under control. According to the rumor, this cooling solution could allow the K90 Ultra to deliver sustained performance levels that rival devices equipped with the newer Snapdragon 8 Elite Gen 5 but without active cooling systems.
If accurate, the move would give REDMI a unique way to narrow the performance gap while potentially keeping costs lower than traditional flagship competitors.
The approach is reportedly aimed at helping the REDMI K90 Ultra compete directly with the HONOR Win and HONOR Win RT, two performance-focused smartphones that are expected to target a similar segment.
Battery life also appears to be a major focus.
The leak suggests the REDMI K90 Ultra will feature a battery capacity exceeding 8,000mAh, placing it among a growing number of smartphones pushing well beyond the battery capacities typically found in premium devices.
Beyond performance and battery life, the K90 Ultra is also rumored to inherit a range of accessories and peripherals similar to those offered with the REDMI K90 Max, which debuted in April. The leak does not specify exactly which peripherals will be included, but the suggestion points to REDMI continuing to build a broader ecosystem around its flagship-tier devices.
For now, REDMI has yet to officially confirm any details about the K90 Ultra. Still, the latest rumor suggests the company is exploring a different formula for flagship competitiveness. One that relies on cooling efficiency and long-term performance rather than simply adopting the newest silicon available.
If the leak proves accurate, the REDMI K90 Ultra could emerge as an interesting alternative for users seeking flagship-level performance, extended battery life, and a potentially lower price tag than devices powered by next-generation chipsets.
