Xiaomi Redmi K90 Pro Max: Comprehensive Review & Specifications

Design and Build Quality

The Xiaomi Redmi K90 Pro Max comes with a sleek and premium design that showcases Xiaomi’s attention to detail. The handset measures 163.3 x 77.8 x 7.9 mm and weighs 218 grams, which makes it slightly on the bigger side but still manageable for everyday use. The device features a robust aluminum frame that adds rigidity and premium look, while the front sports Dragon Crystal Glass protection, enhancing durability and scratch resistance.

The phone supports dual Nano-SIM functionality, catering to users who want seamless dual-line usage. Despite its large 6.9-inch display, the phone maintains an ergonomic contour for comfortable one-hand usage for most users. It is available in four stylish colors: Black, White, Denim Blue, and Lamborghini White, giving users plenty of personalization options.

Display Features

The highlight of the Redmi K90 Pro Max’s front is undoubtedly its stunning 6.9-inch LTPO AMOLED display. The screen boasts a 120Hz refresh rate ensuring buttery smooth animations and scrolling, which is beneficial for gaming and multimedia consumption. Supporting Dolby Vision and HDR10+ standards, the display offers vivid colors and excellent dynamic range, making videos and images pop with depth and clarity.

The resolution stands at 1200 x 2608 pixels (19.5:9 aspect ratio), providing a pixel density of around 416 ppi, which assures sharpness and fine detail rendition. Xiaomi’s utilization of Dragon Crystal Glass on the front not only adds durability but also reduces reflectivity, enhancing visibility even in bright environments.

Peak brightness reaches an impressive 3500 nits, which makes this device one of the brightest available on the market — excellent for outdoor usage under direct sunlight. Additionally, the screen utilizes 2560 billion colors and 2560Hz PWM, which helps reduce eye strain during prolonged use.

Performance and Processing Power

Under the hood, the Redmi K90 Pro Max prides itself on Qualcomm’s latest flagship chipset: the Snapdragon 8 Elite Gen 5 built on a 3nm process node. This chipset features an octa-core CPU setup with 2x4.6 GHz Oryon V3 Phoenix L cores and 6x3.62 GHz Oryon V3 Phoenix M cores. For graphics, the phone uses the powerful Adreno 840 GPU, ensuring excellent gaming performance and smooth graphical rendering for resource-intensive applications.

This combination not only provides blazing fast performance but also improves energy efficiency, helping the battery last longer. Complementing the SoC, users can choose between four different RAM and storage options, including 12GB or 16GB of RAM paired with either 256GB, 512GB, or a massive 1TB of internal storage. However, the device does not offer expandable storage via a microSD card slot.

Software and User Interface

The Redmi K90 Pro Max runs Android 16 paired with Xiaomi's custom HyperOS 3. This latest iteration of HyperOS brings enhanced performance optimizations, smoother animations, improved multitasking, and advanced privacy controls. The software environment is designed to be clean and user-friendly with several customization options, making it one of the most adaptable user interfaces on the market.

HyperOS 3 integrates seamlessly with Android 16’s new features, providing better security, privacy features, and power management. Users can also expect full support for the latest multimedia codecs and APIs, making the device future-proof for upcoming apps and games.

The main camera features a 50MP sensor with f/1.7 aperture, 23mm wide lens, a large 1/1.31-inch sensor size, and 1.2µm pixel size. It uses dual pixel PDAF and Optical Image Stabilization (OIS) to ensure sharp and stable shots even in low light.

Accompanying the main sensor is a 50MP periscope telephoto lens with f/3.0 aperture and 115mm focal length, allowing for 5x optical zoom and OIS support. This setup also uses PDAF to ensure sharp telephoto shots from close-range to infinity focus.

The third camera is a 50MP ultra-wide shooter with an f/2.4 aperture and 102° field of view. It features a 1/2.88-inch sensor designed to capture expansive landscapes and group selfies with accurate colors and less distortion.

Additional features include a color spectrum sensor, LED flash, HDR, and panorama modes to enhance shooting versatility. Video capabilities are equally impressive, with support for 8K recording at 30fps, 4K recording up to 60fps, and slow-motion video from 30fps to an ultra-slow 1920fps at 720p resolution. The device also uses gyro-EIS for stabilization and supports HDR10+ video recording.

For selfies, there is a single 32MP front camera with an f/2.2 aperture and 21mm wide lens that captures detailed portraits and supports 4K video recording at 30fps as well as 1080p recording at up to 60fps.
