The 100W fast charging ensures the battery can be replenished quickly, minimizing downtime.

The Redmi K90 Ultra features a 6.8-inch LTPS OLED display with 1.5K resolution and 165Hz refresh rateproviding smooth visuals and vibrant colors ideal for gaming and media consumption. The display includes rounded corners and a metal frame for premium aesthetics. The device also includes an ultrasonic in-display fingerprint scanner for secure authentication and convenient access.

This feature positions the K90 Ultra as a true gaming phone that prioritizes sustained performance.

The device’s IP69 water and dust resistance rating ensures protection against extreme conditions, including high-pressure water jets and prolonged submersion, making it suitable for users who need durability alongside performance.
