Redmi K90 Ultra is set to launch between May and June, sparking excitement with its rumored features. The smartphone reportedly combines a powerful battery with an innovative cooling system, targeting users who prioritize performance and endurance.
The device is expected to feature a 10,000mAh battery, a rare capacity for modern smartphones. This large battery is complemented by 100W fast charging and wireless charging support, ensuring minimal downtime. Remarkably, the phone may maintain a slim profile around 8.5mm thick despite packing such a huge battery.
Display and Performance
Redmi’s upcoming model is anticipated to sport a 6.8-inch OLED display with a 1.5K resolution and an ultra-high refresh rate of 165Hz. This combination promises exceptionally smooth visuals, ideal for gaming and media consumption. As noted by sources close to the leaks, this may mark one of Redmi’s first Ultra flagship phones to emphasize screen fluidity.
In terms of processing power, the K90 Ultra is rumored to use the MediaTek Dimensity 9500 chipset, not the Plus variant. MediaTek reportedly will not release a Dimensity 9500 Plus this year, prompting Redmi to choose the existing high-performance Dimensity 9500 SoC. This chipset remains competitive, delivering flagship-level speed and efficiency.
Innovative Cooling System
A standout feature of the device is the inclusion of an active cooling fan inside the chassis. This anticipates a growing trend toward active cooling solutions in flagship smartphones to ensure thermals remain stable under heavy loads. The fan aims to prevent thermal throttling during long gaming sessions or intensive tasks, enhancing sustained performance.
Build and Additional Specifications
The Redmi K90 Ultra could also come with an IP68 rating for water and dust resistance, a feature that adds durability for everyday use. Design-wise, the phone is expected to present a minimalistic look with a metal frame and an ultrasonic in-display fingerprint sensor, adding to user convenience and security.

Launch and Market Availability
According to industry insiders, the Redmi K90 Ultra will likely debut in China during the May to June timeframe in 2026. Following Redmi’s traditional approach for the Ultra series, the model might remain exclusive to the Chinese market without a global release. This aligns with previous Ultra editions which focused on technological advancements tailored for specific markets.
The combination of a massive battery, active cooling, and a high refresh rate display could position the Redmi K90 Ultra as a strong contender within the flagship segment in China. It reflects Redmi’s strategic focus on enhancing durability and performance stability along with cutting-edge hardware.
As the release approaches, more details are expected to surface, providing clarity on pricing and additional features. For now, the rumored specs indicate that Redmi is committed to pushing boundaries and catering to power users seeking reliable endurance and smooth performance in a sleek design.
