Redmi K90 Ultra Features and Specifications

The Redmi K90 Ultra is powered by Qualcomm’s flagship Snapdragon 8 Elite chipset, paired with a dedicated D2 discrete graphics chip for improved gaming performance and higher frame rates. The phone offers up to 16GB LPDDR5X Ultra RAM and 512GB UFS 4.1 storage, ensuring smooth multitasking and faster app loading.

One of its biggest highlights is the physical active cooling fan, which operates at just 32dB to keep thermals under control during extended gaming sessions. Xiaomi says the cooling module also carries IPX8 and IPX9 ratings, while the phone itself is certified IP66, IP68, and IP69 for dust and water resistance.

The handset sports a 6.83-inch flat AMOLED display with a 165Hz refresh rate and up to 3,500 nits peak brightness, making it suitable for gaming and outdoor use.

Powering the device is a massive 8,550mAh Jinshajiang battery with 100W wired fast charging and 22.5W reverse wired charging support. Xiaomi has also included a battery bypass charging feature that powers the motherboard directly during gaming, reducing heat buildup and helping preserve long-term battery health.

For photography, the Redmi K90 Ultra features a 50MP primary camera with Optical Image Stabilisation (OIS) alongside an 8MP ultra-wide sensor. A 20MP front-facing camera handles selfies and video calls.

The smartphone also includes a 3D ultrasonic fingerprint scanner, a linear haptic motor, and Bose-tuned stereo speakers for an enhanced multimedia experience. Xiaomi’s partnership with Tencent brings exclusive gaming optimisations, including custom touch controls and dedicated gaming zones for supported titles, further strengthening the Redmi K90 Ultra’s appeal as a performance-focused flagship.
