Redmi K90 Pro Max: Xiaomi’s sub-brand Redmi has once again redefined the concept of an affordable flagship with the launch of its Redmi K90 Pro Max. As the latest and most powerful addition to the Redmi K series, the device pushes performance and multimedia boundaries further than ever before. It brings Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, a massive 7,560mAh silicon-carbon battery, and a Bose-tuned 2.1 channel speaker system — features that position it well above traditional “flagship killers.”
After a long hiatus, the “Pro Max” badge makes its return, signaling that Redmi is not just chasing performance but also expanding into premium hardware design and high-end audio innovation. The K90 Pro Max stands out not only for its processing power but also for its ambitious camera system, which features three 50MP sensors including a periscope telephoto lens, and its stunning 6.9-inch OLED display capable of reaching 3,500 nits of brightness.
Designed for those who demand power, performance, and entertainment, the Redmi K90 Pro Max feels more like a full-fledged multimedia device than a standard smartphone. From the 2.1 channel audio system to the ultra-bright OLED display and flagship-level imaging setup, it aims to rival premium offerings from Samsung, OnePlus, and Vivo — but at a significantly lower price point.

Performance and Software
Under the hood, the Snapdragon 8 Elite Gen 5 SoC powers the K90 Pro Max, promising exceptional performance in CPU, GPU, and AI-driven tasks. Built on a 3nm process, this chipset ensures efficient multitasking, lag-free gaming, and superior thermal management. The processor is paired with up to 16GB of LPDDR5X RAM and 1TB of UFS 4.0 storage, ensuring lightning-fast app launches and file transfers.
The smartphone runs HyperOS 3, Xiaomi’s latest Android skin based on Android 16, offering smoother transitions, enhanced customization, and tight integration with Xiaomi’s AI ecosystem. With AI-powered optimizations and improved energy efficiency, users can expect a consistent flagship experience across performance-heavy workloads and day-to-day operations.
Camera Capabilities
Redmi’s camera ambitions reach new heights with the K90 Pro Max, which packs three 50MP sensors. The primary shooter is the same Light Fusion 950 sensor found in the Xiaomi 17 — a 1/1.31” sensor with OIS, 13.5EV dynamic range, and a 23mm equivalent focal length for crisp, balanced images in all lighting conditions.
The second 50MP periscope telephoto lens supports 5x optical zoom (115mm equivalent), allowing users to capture detailed long-range shots without loss of clarity. The third 50MP ultrawide sensor offers a 102° field of view, perfect for landscapes and group photos.
On the front, a 32MP selfie camera ensures sharp portraits and seamless facial recognition. Combined with advanced image processing powered by Snapdragon’s AI engine, the K90 Pro Max delivers professional-grade results across photography and videography.
Audio System: Bose 2.1 Channel Sound
One of the most distinctive features of the Redmi K90 Pro Max is its Bose-tuned 2.1 channel speaker system. Unlike most smartphones that rely solely on stereo output, the K90 Pro Max incorporates an independent woofer module on the rear, placed next to the camera housing. This configuration provides deeper bass, wider sound separation, and richer acoustic detail, creating an immersive listening experience that rivals dedicated portable speakers.
Redmi claims this system offers class-leading bass depth and clarity, making it ideal for media consumption, gaming, and calls. The addition of Bose sound optimization further refines frequencies for a balanced and cinematic output.
Battery and Charging
The 7,560mAh silicon-carbon battery represents a major technological leap in battery design. The use of silicon-carbon chemistry allows for higher energy density and longer life cycles, enabling more power without increasing weight or thickness.
Charging options are equally impressive:
- 100W wired fast charging fills the battery in under 25 minutes.
- 50W wireless charging provides a cable-free boost.
- 22.5W reverse wireless charging lets users power accessories or other devices.
This combination makes the K90 Pro Max one of the most versatile powerhouses available, ideal for heavy gamers, travelers, and multimedia users.
Connectivity and Security
The phone supports 5G connectivity, Wi-Fi 7, Bluetooth 5.4, and NFC for secure payments. The 3D ultrasonic under-display fingerprint sensor ensures quick and accurate unlocking, even with wet or oily fingers. IP68 certification further guarantees the device’s durability in challenging environments.
Price and Availability
The Redmi K90 Pro Max starts at CNY 3,999 (~$561) for the base variant and goes up to CNY 5,299 (~$743) for the 16GB RAM + 1TB model. It is currently available in China, with global release details expected in the coming weeks. Given the feature set, it stands as one of the most competitively priced flagship smartphones in 2025.
