Redmi K90 Ultra Officially Launched: Everything You Need to Know About the New Redmi K90 Ultra

Xiaomi has once again shaken up the highly competitive mid-range smartphone market with the official introduction of the Redmi K90 Ultra. Following a wave of industry leaks and intense consumer anticipation, the Chinese technology giant unveiled the new device at a launch event in Beijing earlier today. Serving as the direct successor to the widely popular K80 Ultra, the latest iteration promises flagship-level performance, ultra-fast charging, and a refined design language—all wrapped in an aggressive pricing strategy.

Premium Aesthetics and a Top-Tier Display

The Redmi K90 Ultra introduces a sleeker, more polished aesthetic compared to its predecessor. Xiaomi has opted for a glass back and an aluminum frame, giving the device a distinct premium feel that defies its mid-range categorization. The camera module has also been redesigned, now featuring a more integrated and sophisticated look.

At the front, the device boasts a stunning 6.67-inch AMOLED display with a 1.5K resolution. Gamers and multimedia enthusiasts will appreciate the incredibly fluid 144Hz refresh rate, ensuring exceptionally smooth animations and highly responsive touch interactions. Furthermore, the display supports Dolby Vision and HDR10+, delivering vibrant colors and deep contrasts.

Uncompromising Performance and Rapid Charging

Under the hood, the Redmi K90 Ultra is powered by the MediaTek Dimensity 9300+ chipset. Built on a cutting-edge 4nm process, this processor is designed to deliver immense processing power and remarkable thermal efficiency, easily rivaling some of the most expensive flagship devices on the market.

To complement this powerful core, Xiaomi has equipped the phone with up to 24GB of LPDDR5X RAM and a massive 1TB of UFS 4.0 internal storage, ensuring that multitasking and data transfer speeds are virtually instantaneous.

One of the standout features of the K90 Ultra is its battery and charging capabilities. The device houses a robust 5,000 mAh battery, which is designed to easily last a full day of heavy usage. However, the real headliner is the staggering 120W fast wired charging support. Xiaomi claims this technology can fully charge the device from zero to 100% in under 20 minutes, virtually eliminating battery anxiety.

Capable Cameras and Competitive Pricing

In the photography department, the Redmi K90 Ultra features a versatile triple-camera setup on the rear. The primary shooter is a 50MP Sony IMX890 sensor equipped with Optical Image Stabilization (OIS), promising sharp and clear photos even in low-light conditions. This is accompanied by an 8MP ultra-wide-angle lens and a 2MP macro sensor. For selfies and video calls, a 20MP front-facing camera is housed within a discreet punch-hole cutout.

The smartphone ships with Xiaomi’s new HyperOS based on Android 16, offering a clean, customizable, and highly optimized user interface. Additional features include an IP68 rating for water and dust resistance, dual stereo speakers, and an in-display fingerprint scanner.

Currently launched exclusively in China, the Redmi K90 Ultra starts at a highly competitive 2,599 Yuan (approximately $358) for the base 12GB/256GB model. The top-tier configuration with 24GB of RAM and 1TB of storage is priced at 3,599 Yuan (approximately $496). While Xiaomi has not yet confirmed international availability, history suggests the device could reach global markets later this year, potentially rebranded under the Xiaomi ‘T’ series.
