Redmi K90 Ultra Launches June 30 With Built-In Fan at Sub-$440

Redmi has confirmed the K90 Ultra for a June 30, 2026 launch in China at 7 PM local time, with the phone set to debut in a price band under CNY 3,000 (~$440) and pairing that mid-range price tag with a built-in cooling fan, the Snapdragon 8 Elite chipset, and a battery that tipsters say will exceed 8,500mAh.

Redmi Pins the Date and the Price Segment

Redmi confirmed the launch date and price band on Weibo this week. Gizmochina’s write-up of the brand’s announcement shows the company holding a China launch event on June 30 at 7 PM local time. The device is positioned as a “performance-focused gaming flagship” in the 3,000-Yuan (~$440) tier.

That price band has become a focal point for Chinese phone brands, which now routinely drop last-generation flagship silicon into mid-range bodies to chase value-conscious buyers. Gizchina’s reporting on the phone’s 3C certification filing shows tipsters had pointed to a starting price of 2,799 yuan (~$410), though Redmi’s own announcement centres the 3,000-yuan line as the marketing band. The brand has not committed to a final price ahead of the June 30 event. Full specifications will be revealed alongside the final price on the same day, June 30. That date is shared with the OnePlus N6 India launch confirmed for June 30, an 8,000mAh battery phone under Rs 25,000.

The Fan Inside the Chassis

The K90 Ultra uses the same active cooling fan as the Redmi K90 Max, per 91mobiles’ coverage of Xiaomi’s announcement. Xiaomi has claimed the fan can drop the phone’s temperature by up to 10°C in 100 seconds of sustained gaming. The K90 Max was the first Xiaomi Group phone to ship with one, per Gizchina’s reporting on the lineup.

Notebookcheck reported the K90 Max’s fan at 18.1mm in diameter, citing Xiaomi’s launch materials for that phone. Images shared by Redmi on Weibo show the K90 Ultra with a wide air outlet positioned beneath the camera module, per Gizmochina, indicating the fan is deeply integrated into the phone’s structure. Gizchina’s read of the design renders suggests Redmi will continue using an independent cooling architecture similar to the K90 Max. That architecture lets the active fan operate without affecting battery capacity or durability features.

The K90 Ultra extends that hardware to a sub-CNY 3,000 phone for the first time. The K90 Max launched at CNY 3,199 (~$468), and the K90 Ultra sits below it on price. Gizchina frames the K90 Ultra as the same fan-cooling philosophy as the K90 Max, at a 400 yuan lower entry price.

Beyond the fan, the K90 Ultra’s Space Silver colour matches the K90 Max’s launch finish, per Gizmochina’s read of the official renders shared on Weibo. The horizontal camera module and dual-camera arrangement also carry over from the K90 Max’s design, according to Gizmochina. Gizchina’s read of the design renders shows the same rear panel layout in both phones. Redmi has not said whether the K90 Ultra ships with the same camera hardware as the K90 Max, including sensor sizes or image-processing pipelines.

Lu Weibing’s 180-Minute Gaming Claim

Lu Weibing, Xiaomi’s Group President, posted the marquee performance number on Weibo ahead of the launch. His claim: the K90 Ultra sustains 144 FPS in a popular MOBA title at maximum graphics over a 180-minute session at 30°C ambient, with no frequency throttling and no frame drops, per 91mobiles’ summary of his remarks. Redmi has not published the test methodology or any independent verification beyond the Weibo post.

Lu also highlighted a dedicated D2 gaming graphics chip, e-sports touch controls, gaming audio effects, and a landscape-orientation network optimisation mode. The D2 chip appeared in leaks for the K90 Max earlier in 2026, per Notebookcheck’s coverage of the K90 Max launch. E-sports touch controls, gaming audio effects, and landscape network optimisation were also features Xiaomi pitched for the K90 Max, per 91mobiles. The K90 Ultra’s gaming feature set mirrors the K90 Max’s, with the active fan shared between the two devices. The K90 Ultra launches at a CNY 3,000 (~$440) price band; the K90 Max launched at CNY 3,199 (~$468).

The Spec Sheet Taking Shape

Full specifications are still pending the June 30 reveal. Tipsters had an early read on the spec sheet, including a June 24 expected-spec rundown, and the 3C certification filing has surfaced the remaining details.

The clear trade-off in the spec sheet is wireless charging. The 3C filing confirms 100W wired support but does not list wireless charging, per Gizchina’s reporting on the certification. Redmi has not commented on the omission, which is unusual for a phone in this segment. Other details from the same filing include an ultrasonic fingerprint scanner under the display, dual stereo speakers, and IP68 plus IP69 dual water-resistance ratings. The 8,500mAh battery figure remains a tipster number rather than a Redmi-confirmed one; the brand has framed the device only as packing a battery “exceeding 8,500mAh.”

What remains unconfirmed at the June 30 reveal includes the final price, the exact display panel, and any regional launch plans outside China. Below is a quick read of where each detail currently sits, with the source for each line. Once Redmi publishes the full spec sheet on June 30, this list will need to be updated.

1. Confirmed by Redmi on Weibo: June 30 launch date, CNY 3,000 price band, Snapdragon 8 Elite chipset, built-in active cooling, Space Silver colour.
2. From the 3C filing (per Gizchina): 100W wired charging, IP68 and IP69 ratings, model number M332BF.
3. From tipsters, including a June 24 expected-spec rundown: 8,500mAh+ battery, 1.5K OLED up to 165Hz, ultrasonic fingerprint scanner, no wireless charging.
4. Pending June 30: final price, full spec sheet, regional availability.

Where the K90 Ultra Sits in Redmi’s Lineup

Redmi’s K90 family now spans four models: the K90, the K90 Pro Max, the K90 Max, and the incoming K90 Ultra. Per Gizchina’s read of Digital Chat Station’s reporting, the Ultra name sits below the Pro Max and Max in hierarchy. The arrangement is down to the chipset choice. The K90 Pro Max uses a Snapdragon 8 Elite Gen 5, and the Max uses a Dimensity 9500, both newer silicon than the Snapdragon 8 Elite in the K90 Ultra.

The K90 Max launched April 21 at CNY 3,199 (~$468), per Notebookcheck’s coverage of its launch, shipping with the Dimensity 9500 and an 8,550mAh battery. The Redmi Note 17 leak pointing to a 9,000mAh battery tracks a similar capacity play into the Note series ahead of a July China launch. The K90 Max carries IP66 alongside IP68 and IP69, while the K90 Ultra’s 3C filing lists IP68 and IP69 without IP66.
