Redmi is reportedly working on the Redmi K90 Ultra for China. It will succeed the Redmi K80 Ultra, which debuted in June 2025. A previous report claimed that the K90 Ultra would launch much earlier than its predecessor. Now, a new Weibo post by a reliable tipster has emerged supporting this claim.
Redmi K90 Ultra launch timeframe (rumored)
According to Experience More, a sub-series performance-focused smartphone powered by the Dimensity 9500 is currently in development. While he did not mention the name of the device, it appears that he could be referring to the Redmi K90 Ultra.
He added that the device, carrying the model number 2604FRK1EC, is said to feature an ultra-high refresh rate display along with a built-in cooling fan, indicating a strong focus on gaming and sustained performance. This model number, along with its Redmi K90 Ultra branding, was spotted in the GSMA IMEI database back in December 2025.
The numbers “2604” indicate that the Redmi K90 Ultra may debut as early as April in China. The device will be powered by the Dimensity 9500, not the Dimensity 9500 Plus chip as previously speculated. The D9500+ is expected much later in the second half of the year.
As per reports, the K90 Ultra is expected to feature a massive 6.8-inch display offering a 1.5K resolution and a 165Hz refresh rate. Under the hood, it may pack an 8,500mAh battery with 100W charging. Other rumored features include a metal frame, an ultrasonic in-display fingerprint sensor, and full water resistance.
The Xiaomi 17T Pro is said to be a tweaked version of the K90 Ultra designed for the global market. This device, which is said to carry the model number 2602EPTC0G, may lack a few features, including the cooling fan. The model number for the 17T Pro also hints at an early launch, but since the Xiaomi 17 and 17 Ultra have not yet launched globally, it appears that the 17T Pro may debut within the first half of this year.
