Redmi K90 Max Specifications and Features
The dual-SIM Redmi K90 Max runs Android 16-based HyperOS 3. Its 6.83-inch 1.5K (1,280 x 2,772 pixels) M10 display supports up to 165Hz refresh rate, a 480Hz touch sampling rate, 3,500Hz instantaneous touch sampling, 480Hz multi-finger touch sampling, and peaks at 3,500 nits brightness. The panel also carries HDR10+ and Dolby Vision certification.
Under the hood sits a MediaTek Dimensity 9500 chipset, paired with up to 16GB of LPDDR5x RAM and up to 1TB of UFS 4 storage. A dedicated D2 display chip handles gaming-focused processing. Thermal management is taken seriously here — the phone features a 6,000 sq mm ice-sealed circulating cooling pump and over 12,000 sq mm of graphite coverage, plus an active cooling fan that Redmi claims can bring temperatures down by around 10°C in just 100 seconds.
The rear camera system consists of two sensors: a 50-megapixel main camera with OIS and an f/1.68 aperture, backed by an 8-megapixel secondary shooter. On the front, a 20-megapixel camera covers selfies and video calls. Audio is handled by a 1115x symmetrical stereo dual-speaker setup, co-tuned with Bose.
Connectivity is comprehensive, covering 5G, Wi-Fi 7, Bluetooth 4, NavIC, GPS/AGPS, Galileo, GLONASS, BeiDou, NFC, OTG, and USB Type-C. The phone carries IP66, IP68, and IP69 ratings for dust and water resistance. Security is managed by a 3D ultrasonic in-display fingerprint sensor, and the onboard sensor array includes an accelerometer, ambient colour temperature sensor, electronic compass, gyroscope, IR remote control, flicker sensor, and an X-axis linear motor.
Powering everything is the 8,550mAh battery, which supports 100W wired fast charging and 22.5W reverse wired charging for topping up other devices on the go.
