The Redmi K90 Pro Max redefines the “flagship killer” category in late 2025 with a monstrous 7,560mAh battery and PC-grade gaming performance.
Powered by the Snapdragon 8 Elite Gen 5 and featuring a unique Bose-tuned 2.1 speaker system, it is a multimedia beast.
While the massive 6.9-inch screen and industrial design may be bulky for some, the hardware value is undeniable.

Design & Build Quality
The Redmi K90 Pro Max abandons the curved trends of the past for a bold, flat-edged industrial aesthetic. The back panel comes in a unique “Tech Denim” texture that resists fingerprints, alongside standard Golden White and Matte Black glass options.
Durability is a priority, featuring “Dragon Crystal Glass” on the front and a reinforced aluminum mid-frame. It carries both IP68 and IP69 ratings, ensuring survival against submersion and high-pressure water jets.
At 218g and 7.9mm thick, it manages to hide its massive battery well, though the large rectangular camera island dominates the upper rear, causing a slight wobble on flat surfaces.
Display
The device sports a massive 6.9-inch M10 LTPO OLED panel that is a visual treat. It offers a sharp 1.5K resolution (1200 x 2608 pixels) and supports a variable refresh rate from 1Hz to 120Hz.
Brightness is exceptional, hitting a global peak of 3,500 nits, making outdoor visibility effortless. The “Qingshan Eye Protection 3.0” ensures reduced eye strain with high-frequency PWM dimming.
Colors are punchy and accurate, with full coverage of the DCI-P3 gamut. HDR10+ and Dolby Vision support make streaming content look cinematic, especially on such a large canvas.
Performance
At its core lies the Snapdragon 8 Elite Gen 5 (3nm), paired with a dedicated D2 graphics chip. This combination obliterates benchmarks, scoring over 4 million on AnTuTu.
Real-world gaming is flawless. Titles like Genshin Impact and Zenless Zone Zero run at a locked 120fps at maximum settings, thanks to the 3D Ice-Sealed cooling system that keeps thermals in check.
With up to 16GB of LPDDR5X RAM and 1TB of UFS 4.1 storage, multitasking is instant. Apps remain in memory for hours, and file transfers are lightning-fast.
Camera System
Redmi has shed its “performance-first, camera-second” reputation. The triple 50MP setup is versatile and capable.
- Main: 50MP Light Hunter 950 sensor with OIS delivers excellent dynamic range and night shots that rival premium flagships.
- Telephoto: The 50MP periscope lens offers 5x optical zoom and 10x lossless hybrid zoom, a rarity in this price segment.
- Ultrawide: The 50MP ultrawide captures detail-rich landscapes without significant edge distortion.
Video recording peaks at 8K 30fps, with 4K 60fps offering rock-steady stabilization. AI features like “Magic Eraser 4.0” and live translation work entirely on-device.
Battery & Charging
The standout feature is the 7,560mAh silicon-carbon battery. It easily provides two full days of heavy use, clocking over 12 hours of screen-on time in mixed testing.
Charging is rapid with the included 100W GaN charger, filling the massive cell in just under 35 minutes.
- Wired: 100W (0-100% in ~35 mins)
- Wireless: 50W (requires proprietary stand)
- Reverse: 22.5W (charges accessories quickly)
Software & Extra Features
Running Android 16 with HyperOS 3.0, the interface is smoother and more interconnected than before. Bloatware is reduced, though still present.
The audio is a game-changer: a 2.1 channel setup co-engineered with Bose, featuring a dedicated sub-woofer unit for genuine bass response.
Connectivity is future-proof with Wi-Fi 7, Bluetooth 5.4, and an ultrasonic fingerprint sensor that works with wet hands.

Comparison with Competitors
