Digital Chat Station leaks detailed specs for Redmi's upcoming gaming-focused flagship, including Dimensity 9500, 165Hz display, active cooling, and massive battery.
The Redmi K90 Ultra is shaping up to be a serious gaming contender after a detailed leak from Digital Chat Station revealed the phone's core specifications. The upcoming flagship, expected to launch in China in April 2026, appears designed to compete directly with gaming-focused devices like the RedMagic 11 Pro.
According to the leak, the Redmi K90 Ultra will feature a "1.5K" LTPS display with a 165Hz refresh rate. This high refresh rate matches what we see on devices like the OnePlus 15, promising smooth, responsive gameplay that's essential for competitive mobile gaming. The combination of the display technology and refresh rate suggests Xiaomi is prioritizing visual performance for gamers.
Powering the device will be MediaTek's Dimensity 9500, currently the company's top-end mobile processor. While the Dimensity 9500 doesn't quite match the Snapdragon 8 Elite Gen 5 in gaming and emulation scenarios, Digital Chat Station suggests optimizations could enable 165 FPS performance in most mainstream games. This positions the K90 Ultra as a capable gaming device, even if it's not quite at the absolute cutting edge of mobile gaming performance.
One of the most interesting revelations is the inclusion of an active cooling fan. This feature directly targets the gaming market, where sustained performance under heavy loads is crucial. The cooling fan would allow the phone to handle AAA gaming sessions without thermal throttling, making it a direct competitor to the RedMagic 11 Pro, which also features internal cooling. This suggests Xiaomi is taking mobile gaming seriously and wants to offer a solution to one of the biggest challenges in smartphone gaming: heat management.
Battery life appears to be another priority, with the leak mentioning a battery capacity exceeding 8,000mAh. Combined with the efficient Dimensity 9500 and active cooling, this could provide excellent battery life even during extended gaming sessions. The report also confirms earlier rumors about custom-tuned symmetrical dual speakers with Bose tuning, promising high-quality audio for both gaming and media consumption.
Additional gaming-focused features include an ultrasonic fingerprint sensor for quick access, an IP68 rating for durability, a dedicated graphics chip for enhanced gaming performance, and a large vibration motor for haptic feedback. These features collectively suggest a device built from the ground up for gaming enthusiasts.
While the Redmi K90 Ultra won't launch until April 2026, these leaked specifications paint a picture of a well-rounded gaming phone that could offer excellent value compared to more expensive gaming-focused devices. The combination of high refresh rate display, capable processor, active cooling, and gaming-specific features positions it as a strong contender in the mobile gaming market.
For users considering an upgrade from previous Redmi models, the K90 Ultra represents a significant leap forward in gaming capabilities. The phone appears to address many of the limitations that mobile gamers typically face, from thermal throttling to battery life to display responsiveness.
The leak doesn't mention pricing, but given Redmi's positioning as a value-focused brand, the K90 Ultra could offer compelling specifications at a more accessible price point than dedicated gaming phones from brands like RedMagic or ASUS ROG.
As we approach the April 2026 launch window, more details about the Redmi K90 Ultra will likely emerge. For now, this leak suggests Xiaomi is making a serious play for the mobile gaming market with a device that combines high-end specifications with gaming-specific features and active cooling technology.
