The Redmi K90 Pro Max stays true to its minimalist roots while showcasing premium craftsmanship that conveys a high-end, sophisticated look. Measuring 163.33 x 77.82 x 7.9 mm and weighing approximately 218 grams, the device feels comfortable in hand and makes a strong impression in both professional and everyday settings. The built-in subwoofer on the back is an eye-catching design element that hints at its superior audio performance. With IP68 certification, the phone is fully protected against dust and water, making it resilient in challenging environments.

At the heart of the Redmi K90 Pro Max lies the Qualcomm Snapdragon 8 Elite Gen 5 chipset, clocking in at up to 4.6 GHz—setting new benchmarks for flagship performance. Paired with the Adreno 840 GPU, this powerful SoC ensures smooth multitasking and top-tier gaming performance. An advanced multi-layer cooling system efficiently dissipates heat, maintaining peak performance even under sustained heavy loads.

Photography takes center stage with a high-resolution 50 MP triple camera setup. The main sensor features the cutting-edge Lighthunter 950 with OIS (Optical Image Stabilization) and a large 1/1.31" sensor size, capturing stunning images even in low-light conditions. A second 50 MP ultra-wide-angle lens with an f/2.4 aperture enables expansive panoramic shots, while a third 50 MP telephoto lens with f/3.0 aperture and 5x optical zoom brings distant subjects closer. For selfies, a 32 MP front-facing sensor is housed within the display’s punch-hole cutout.

The Redmi K90 Pro Max boasts a massive 6.9-inch OLED panel with a sharp resolution of 2608 x 1200 pixels and a buttery-smooth 120 Hz refresh rate. Supporting 12-bit color depth and HDR10+, the display delivers vibrant, accurate colors and deep contrasts. Peak brightness reaches an impressive 3500 nits, ideal for outdoor visibility, while nighttime use is enhanced by the ability to dim down to just 1 nit for comfortable viewing in the dark.

Marking a major collaboration, Xiaomi has partnered with audio giant Bose to elevate the Redmi K90 Pro Max’s sound quality. Featuring dual stereo speakers and a built-in subwoofer, the device delivers rich, room-filling audio. Bose has fine-tuned two distinct sound profiles: Classic Mode emphasizes deep bass, while Balanced Mode offers a refined blend of highs and lows. This integration sets a new standard for audio performance in its price segment. Additional features include Bluetooth 5.4, Wi-Fi 7, and an in-display fingerprint sensor.

Powering the Redmi K90 Pro Max is a high-capacity lithium-ion battery, model BM75, with an exceptional 7560mAh capacity. This ensures all-day (and often multi-day) usage on a single charge. Complementing this is 100W fast charging, allowing users to recharge the massive battery in record time—minimizing downtime and maximizing productivity or entertainment.

Conclusion

The Redmi K90 Pro Max (Battery Model BM75, 7560mAh) redefines what a value-driven flagship can achieve. Combining top-tier performance, a professional-grade camera system, a brilliant display, and now studio-quality audio co-engineered with Bose, it poses a serious challenge to much more expensive competitors. Whether you're a mobile gamer, photography enthusiast, or business professional, the K90 Pro Max delivers excellence across the board.
