Xiaomi 15 Ultra RAM: 16GB Internal Storage: 512GB

The Xiaomi 15 Ultra, launched in February 2025, is Xiaomi’s most advanced flagship smartphone to date, positioned as a premium device for photography enthusiasts, tech power users, and anyone seeking high-end performance. It builds on the success of the 14 Ultra, refining key hardware areas and further deepening its partnership with Leica for mobile imaging excellence.

Display & Design

The device features a 6.73-inch LTPO AMOLED display with a resolution of 3200 x 1440 pixels, supporting 120Hz adaptive refresh rate, HDR10+, Dolby Vision, and an extraordinary peak brightness of 3200 nits, ensuring visibility even under direct sunlight. It is protected by Xiaomi Shield Glass 2.0 and has a premium build combining an aluminum frame with either eco-leather or glass-fiber back panels. Despite its large camera module, the phone maintains a sleek form factor at 9.4mm thickness and 226g weight.

Performance

Under the hood is Qualcomm’s latest Snapdragon 8 Gen 4 (branded Elite), built on a 3nm process for efficiency and raw power. Paired with 12GB or 16GB of LPDDR5X RAM and 256GB to 1TB UFS 4.1 storage, the 15 Ultra handles multitasking, gaming, and AI-based tasks with ease. It runs on Android 15, skinned with Xiaomi’s HyperOS 2, offering fluid transitions and deep integration with the Xiaomi ecosystem.
