Xiaomi 15 Ultra

Xiaomi is one of the most popular smartphone manufacturers in the world that garnered the attention of the world with “flagship killer” phones. Like similar companies before it, it gradually shifted to the flagship space itself with a series of phones named after itself. The Xiaomi 15 Ultra is the company's flagship offering for the year 2025.

Xiaomi 15 Ultra Overview

Leica Quad-Camera System

The Ultra series remains heavily focused on photography, even more so than Samsung and Apple’s flagships. It retains the large circular quad-camera module inspired by Leica cameras and is available in three versions: two-tone silver and black, along with plain black and white models. The biggest upgrade in the camera system is a 200MP periscope camera with 4.3x zoom, offering improved low-light performance through a larger sensor, faster aperture, and higher resolution. Xiaomi refers to the phone as “Night God” to highlight its low-light photography capabilities. The other three cameras are 50MP each, with minor adjustments from the 14 Ultra. Notably, the main camera now has a fixed f/1.63 aperture, replacing the variable aperture from the previous model. Additionally, the third-generation Photography Kit, an optional accessory, includes a case and a camera grip. It features a new red finish, a larger 2,000mAh battery that doubles as a power bank, and retains the same controls: shutter button, video button, zoom lever, and exposure dial.

Display and Design

The phone features a 6.73-inch WQHD+ AMOLED display with a 120Hz refresh rate and peak brightness of up to 3200 nits. It supports HDR10+ and Dolby Vision. The design incorporates Xiaomi’s Guardian Structure with Gorilla Glass protection and IP68 water and dust resistance.

Performance and Software

The Xiaomi 15 Ultra is powered by the Snapdragon 8 Elite processor, paired with LPDDR5X RAM and UFS 4.0 storage.  Compared to its predecessor, the 8 Elite has a significant performance margin. However, if you do not care about playing high-performance requiring games, the performance might just even be an overkill. Meanwhile,  It runs on Xiaomi HyperOS 2.0, based on Android 15. The device includes a 3D dual-channel cooling system. In addition, Xiaomi has bought various AI features in its system. Xiaomi’s HyperAI features include a Creative Assistant and a Productivity Assistant. The Creative Assistant enables object removal, sky and reflection enhancement, blur reduction, and AI-driven image and video editing. The Productivity Assistant provides context recognition for tasks such as text, translation, and search, along with voice recognition for transcription and instant translation. It utilizes Google Gemini Nano 2 and Google Circle-to-Search for functionality.

Battery and Charging

It houses a 5110mAh battery with support for 90W wired and 80W wireless charging. It also offers 18W reverse wireless charging. Xiaomi claims the battery retains 80% capacity after four years of use. The phone supports dual SIM, Bluetooth 6.0, WiFi 7, NFC, and USB Type-C 3.2 Gen 1.
