Audio is another key selling point, with Xiaomi touting a 200 per cent volume boost supported by Hi-Res Audio and Dolby Atmos, delivering louder and more immersive sound for gaming, streaming and music.

The handset runs on the Snapdragon 685 Mobile Platform built on a 6nm process, paired with up to 16GB RAM through memory extension and expandable storage of up to 2TB. It ships with Xiaomi HyperOS 2, bringing features such as Circle to Search, Google Gemini integration and Xiaomi’s cross-device connectivity tools.

Photography duties are handled by a 50MP AI dual rear camera, while an 8MP front-facing camera caters for selfies and video calls. The device also includes Auto Night Mode to enhance low-light photography.
