Xiaomi is said to be developing two new smartphones, with the Redmi K90 Ultra being one of them. Recent leaks indicate that this high-end model will feature some impressive characteristics, including speakers tuned by Bose. According to a comprehensive report by Digital Chat Station, a well-known leaker, key specifications of the device have been revealed.
Display and Refresh Rate
Among the newly revealed information is a “1.5K” LTPS display that is rumored to have a refresh rate of 165Hz. This means that the Redmi K90 Ultra could deliver a display performance similar to that of the OnePlus 15, which also boasts a 165Hz screen.
This high refresh rate could make the smartphone an excellent option for gamers. Digital Chat Station also mentions that the device will be equipped with the Dimensity 9500, the latest top-tier SoC from MediaTek. While it doesn’t quite match the Snapdragon 8 Elite Gen 5 in gaming and emulation capabilities, it remains a solid processor.
Gaming Performance and Cooling
With the right optimizations, this SoC could allow the smartphone to achieve 165 FPS in most popular games. Another exciting detail from the report is the addition of an active cooling fan. This feature positions the Redmi K90 Ultra as a direct rival to the RedMagic 11 Pro, which also comes with internal cooling.
The presence of a cooling fan implies that the Redmi K90 Ultra can sustain intense tasks, such as AAA gaming, over extended periods without experiencing performance drops. Digital Chat Station notes that the phone will be equipped with a battery exceeding 8,000mAh and confirms that it will include custom-tuned symmetrical dual speakers.
Additional Features
Other intriguing details from the report include an ultrasonic fingerprint sensor, an IP68 rating for water and dust resistance, a dedicated graphics chip to boost gaming performance, and a sizeable vibration motor. All these features would make the upcoming phone a significant upgrade over its predecessor (12/256GB currently priced at $376.41 on TradingShenzhen). While a specific release date hasn’t been provided, the Redmi K90 Ultra is anticipated to debut in China in April 2026.
