Redmi K90 Ultra: First Leaks of a XXL Model Designed for Performance
Just a few months after the release of the Redmi K90 and K90 Pro Max, initial rumors regarding the Redmi K90 Ultra are already circulating. This model, based on leaks, is said to push endurance and power even further, reaffirming Xiaomi’s aggressive expansion strategy in the performance segment.
Redmi K90 Ultra: An Anticipated Successor Already a Topic of Discussion
The Redmi K90 Ultra is expected to be released several months after the first models in the series—possibly in mid-2026 if Redmi follows the schedule of the K80 Ultra. However, the smartphone is already generating buzz, fueled by the first tidbits from Digital Chat Station. While nothing is official yet, there are enough hints to outline what the upcoming “Ultra” model from the brand could look like.
According to these leaks, Xiaomi is clearly aiming to distinguish the upcoming Redmi K90 Ultra from its siblings, the Redmi K90 and Redmi K90 Pro Max, by focusing on a faster display, a massive battery, and a design heavily geared towards gaming.
The Redmi K90 Ultra is said to feature a 6.8-inch LTPS OLED display with a 1.5K resolution and an impressive refresh rate of 165 Hz. This choice would position it among the most fluid smartphones on the market, falling somewhere between a premium device and a dedicated gaming machine.
The frame would be made of metal, indicating a more robust design. The device would also benefit from enhanced water resistance, aligned with the high standards of premium competitors. Other discussed features include an ultrasonic fingerprint sensor under the display and an upgraded audio system.
A Gigantic Battery to Last Longer
Probably the most notable information is that the Redmi K90 Ultra could sport a battery close to 8,000 mAh. Such a capacity is rare in a “mainstream” smartphone, placing this model in a unique category, ideal for intensive gaming sessions or multimedia marathons.
The phone could also utilize a software layer dedicated to high refresh rates, optimized for gaming performance—another sign that Redmi is targeting users seeking a durable and powerful device.
MediaTek Support with the Upcoming Dimensity 9500 Plus in Sight
Under the hood, rumors suggest a MediaTek Dimensity 9-series chipset, possibly the Dimensity 9500+, expected in 2026. This is a yet-to-be-officialized chip presented as the next big step for MediaTek in the high-end market.
No reliable information has surfaced regarding the camera, although sources indicate a “performance-oriented” smartphone, which suggests that Redmi will prioritize a solid configuration without necessarily competing with flagship photography standards.
A Clear Strategy: Taking the Performance Segment Further
By focusing on a 165 Hz display, an extraordinary battery, and a future high-end SoC, Redmi appears to be aiming to solidify its position: offering high-performance smartphones at consistently aggressive prices. This Redmi K90 Ultra could also pave the way for an international variant rebranded under the Xiaomi name, as seen with other models.
If these rumors hold true, the Redmi K90 Ultra could become one of the most appealing phones for mobile gamers and intensive users. Now we just need to await the first official images and, importantly, the confirmation of this XXL battery.
