Redmi is reportedly preparing an ultra variant for the K90 series shortly after unveiling the Redmi K90 and K90 Pro Max in October 2025. Early leaks suggest the Redmi K90 Ultra will bring significant upgrades, focusing on a large battery and powerful chipset to enhance flagship-level performance.
The Redmi K90 Ultra is expected to house an 8,000 mAh battery, a notable increase compared to its predecessor, the K90 Pro Max. This substantial capacity aims to deliver extended battery life, making it a key feature that stands out for heavy users and gamers alike.
In addition to hardware, the device is rumored to include software optimizations that support a high frame rate. According to sources such as Digital Chat Station, this combination of large battery and optimized software could make the K90 Ultra a strong contender in the gaming smartphone market.
Display and Design
The K90 Ultra is likely to feature a 6.8-inch LTPS OLED display with a 1.5K resolution, providing clear and sharp visuals. It will support a 165 Hz refresh rate, which is impressive for this segment, ensuring smooth motion in gaming and everyday use.
Design-wise, the screen is rumored to have curved edges for a more immersive viewing experience. The handset may also feature a metal frame to boost durability and offer a premium feel consistent with flagship devices.
Water resistance is expected to be upgraded to better protect the phone against accidental exposure to moisture. The device will reportedly include an ultrasonic under-display fingerprint sensor, which promises faster and more accurate unlocking compared to traditional optical sensors.
Audio capabilities are also anticipated to receive an enhancement, although detailed specifications have not been disclosed yet. This aligns with the phone’s positioning as a multimedia and gaming-focused device.
Powered by MediaTek Dimensity 9 Series
The Redmi K90 Ultra is set to be powered by a chipset from MediaTek’s Dimensity 9 series. Industry insiders anticipate the Dimensity 9500 Plus to be the likely candidate, expected to launch in 2026.
This chipset choice demonstrates Xiaomi’s strategy to diversify its supply chain, following trends set by the earlier Redmi K90 Pro models. The Dimensity 9500+ is known for delivering strong performance while maintaining power efficiency.
Details about the camera setup remain scarce, but sources indicate that the K90 Ultra will prioritize performance over high-end photographic features. This differentiates it from the previous Pro version, which focused more on camera improvements.
Launch Timeline and Market Positioning
The Redmi K90 Ultra might follow a similar release pattern as its predecessor, the Redmi K80 Ultra, which launched in mid-2025. If Xiaomi adheres to this schedule, the K90 Ultra could debut around mid-2026, initially targeting the Chinese market.
There is also speculation about a global variant or a rebranded model for international audiences, similar to how the Redmi K90 Pro was adapted into the Poco F8 Ultra. This approach allows Xiaomi to maximize its market reach while offering tailored features.
With its massive battery, high refresh rate display, and advanced chipset, the Redmi K90 Ultra is positioned to attract consumers looking for a capable device for gaming and productivity. These strengths may help Xiaomi solidify its presence in the upper mid-range to flagship segment.
Further information on official specifications and pricing in USD is expected as the launch date approaches. Potential buyers and tech enthusiasts should watch for announcements to confirm these preliminary details.
