The Redmi K90 has officially launched, raising the bar for high-performance smartphones with a comprehensive suite of flagship-grade features. From its cutting-edge chipset and ultra-bright display to its massive battery and versatile camera system, every aspect of the K90 is engineered for peak performance and everyday reliability.

Flagship Performance: Snapdragon® 8 Gen 3 Mobile Platform

At its core, the Redmi K90 is powered by the Qualcomm Snapdragon® 8 Gen 3 Mobile Platform, built on an advanced TSMC 3nm process. With a peak CPU clock speed of 4.32GHz and an integrated Adreno™ GPU, the device delivers exceptional processing power and graphics performance—ideal for demanding gaming, multitasking, and AI-driven applications.

Memory and storage options include up to 16GB of LPDDR5X RAM and 1TB of UFS 4.0 storage, ensuring lightning-fast app launches, smooth transitions, and ample space for apps, photos, and media.

The K90 features a 6.59-inch flat OLED display with a resolution of 2510 × 1156 pixels. It supports a 120Hz adaptive refresh rate and a 480Hz touch sampling rate, offering fluid scrolling and ultra-responsive touch input.

The screen covers the full P3 color gamut and supports 12-bit color depth (68.7 billion colors) for rich, accurate visuals. With a peak brightness of 3500 nits in various scenarios, content remains clearly visible even under direct sunlight.

Importantly, the display uses full-range DC dimming across all brightness levels to reduce eye strain. It also supports HDR10+, HDR Vivid, and Dolby Vision, and integrates 3D ultrasonic fingerprint recognition for fast, secure unlocking—even with wet fingers.

Redmi K90 is equipped with a massive 7100mAh (typical) / 6960mAh (minimum) lithium-polymer battery—officially designated as model BM76—delivering multi-day endurance for most users without compromising on form factor.

Power management is handled by Xiaomi’s self-developed Pengpai P3 charging chip and Pengpai G1 battery gauge chip, enabling intelligent power distribution and precise battery monitoring. The device supports 100W wired turbo charging for rapid replenishment, as well as 22.5W wired reverse charging to power accessories like earbuds or smartwatches.

Charging compatibility includes widely used standards such as QC 2.0/3.0/3+, PD 2.0/3.0, via a USB Type-C port. A compact, high-efficiency 100W GaN (gallium nitride) charger is included in the box.

The rear camera array combines three sensors for flexible photography:

• Main Camera: 50MP Light Hunter 800 sensor (1/1.55") with OIS, f/1.88 aperture, and 4-in-1 pixel binning (2.0μm effective pixel size) for superior low-light performance and dynamic range.

• Telephoto Lens: 50MP sensor with f/2.2 aperture, optimized for portraits and mid-range shots.

• Ultra-Wide Lens: 8MP sensor with a 120° field of view and f/2.2 aperture for expansive landscapes and group photos.

Video capabilities include 8K@30fps, 4K@60fps, and slow-motion recording up to 960fps.

The front-facing 20MP camera supports features like gesture shutter, teleprompter mode, portrait bokeh, real-time beautification, and multiple watermark styles—making it ideal for vlogging and video calls.

Measuring 157.49 × 75.25 × 8.0 mm and weighing 206g, the K90 balances a large battery with a comfortable, ergonomic form. The back features a signature square quad-camera module, while the aluminum frame bears a subtle “REDMI” logo for added sophistication.

Additional highlights include dual symmetrical stereo speakers, an infrared blaster for controlling home appliances, and X-axis linear vibration motor for tactile feedback. The device runs Xiaomi HyperOS, delivering a smooth, intuitive, and secure user experience.
