Xiaomi Redmi K90 Specifications
The Redmi K90, announced and released on October 23, 2025, enters the market as a powerful upper-midrange phone with a flagship feel. It has a sturdy aluminum frame with a glass front and carries an IP68 rating, making it resistant to dust and water. The front is dominated by a 6.59-inch AMOLED display with a sharp 1156 × 2510 resolution, 419 ppi density, HDR10+, Dolby Vision, and a super-bright 3500-nit peak. The 120Hz refresh rate and 2560Hz PWM dimming make the screen smooth and comfortable for long use. Available in Black, White, Blue, and Purple, the phone also includes reliable stereo speakers tuned by Bose, adding a premium touch to the multimedia experience.
Performance is one of the K90’s strongest areas thanks to the Snapdragon 8 Elite chipset built on a 3nm process. The octa-core Oryon V2 CPU and Adreno 830 GPU offer excellent speed for gaming, multitasking, and heavy apps. It runs on Android 16 with HyperOS 3 and comes in several storage options including 12GB or 16GB RAM and up to 1TB UFS storage, although there’s no card slot. The triple-camera system includes a 50MP main sensor with OIS, a 50MP telephoto lens with 2.5x optical zoom, and an 8MP ultrawide camera. Video recording goes up to 8K30 with gyro-EIS and HDR10+, while the 20MP selfie camera handles clean 1080p video. An ultrasonic in-display fingerprint sensor and full connectivity support like Wi-Fi 7, Bluetooth 5.4, NFC, and an infrared port complete the package.
The large 7100mAh silicon-carbon battery is another highlight, offering long endurance even under heavy use. The phone supports 100W wired fast charging using PD3.0, QC3+, and PPS standards, and it can also reverse-charge other devices at 22.5W. With USB-C, Hi-Res wireless audio, dual-SIM support, and a price of about $401 (Rs 35,990 in India), the Redmi K90 stands out as a strong value-for-money device. It blends premium build quality, a brilliant display, powerful performance, and versatile cameras into a well-rounded phone that feels more expensive than it is.
