Xiaomi 15T 12GB+512GB – Leica Photography Meets Flagship Performance

The Xiaomi 15T 12GB+512GB brings together professional Leica imaging, powerful performance, a large 1.5K AMOLED display and high-speed connectivity in a premium smartphone designed for demanding everyday users.

Powered by the MediaTek Dimensity 8400-Ultra processor and equipped with 12GB LPDDR5X RAM and 512GB UFS 4.1 storage, the Xiaomi 15T delivers fast application performance, smooth multitasking and ample space for apps, photographs, videos and files.

At the heart of its photography system is a Leica triple-camera setup, combining a 50MP main camera with OIS, a 50MP telephoto camera and a 12MP ultra-wide camera. The phone also features a 32MP in-display selfie camera and supports advanced video recording, including 4K at up to 60fps.

Leica Triple Camera System

The Xiaomi 15T features a Leica triple-camera system designed to provide greater versatility across different shooting situations.

The setup consists of a:

• 50MP Leica main camera with Light Fusion 800 sensor, f/1.7 aperture and OIS
• 50MP Leica telephoto camera with f/1.9 aperture and 46mm equivalent focal length
• 12MP Leica ultra-wide camera with f/2.2 aperture and 120° field of view

This combination provides multiple perspectives, from wide landscape photographs to portraits and closer telephoto shots. Xiaomi also provides Leica Authentic and Leica Vibrant photographic styles, Leica filters and several professional photography modes.

50MP Light Fusion 800 Main Camera with OIS

The primary camera uses a 50MP Light Fusion 800 image sensor with a 1/1.55-inch sensor size and 2.0μm 4-in-1 Super Pixel technology.

Its f/1.7 aperture and optical image stabilisation (OIS) help the camera capture detailed photographs while reducing the effects of camera movement, particularly when shooting in challenging lighting conditions.

50MP Leica Telephoto Camera

The dedicated 50MP Leica telephoto camera provides a 46mm equivalent focal length and f/1.9 aperture.

It is particularly useful for portraits and subjects that benefit from a more natural telephoto perspective. Xiaomi also provides a master-lens system with 23mm, 35mm, 46mm and 75mm focal-length options through its computational imaging system.

12MP Leica Ultra-Wide Camera

For landscapes, architecture, group photographs and wider compositions, the Xiaomi 15T features a 12MP Leica ultra-wide camera with a 120° field of view and 15mm equivalent focal length.

The three-camera arrangement provides a broader range of perspectives without relying solely on digital zoom.

Professional 4K Video Recording

The Xiaomi 15T supports 4K video recording at 30fps and 60fps using the rear camera system.

It also supports 10-bit Log video, HDR10+ video across focal lengths and professional video functions, providing additional flexibility for users who want greater control over their video footage and post-production workflow.

32MP In-Display Selfie Camera

For selfies and video calls, the Xiaomi 15T features a 32MP in-display front camera with an f/2.2 aperture and 21mm equivalent focal length.

The front camera supports HDR, Portrait mode, palm and voice shutter functions and video recording up to 4K at 30fps.

6.83-Inch 1.5K AMOLED Display

The Xiaomi 15T features a large 6.83-inch AMOLED display with a 2772 × 1280 resolution, approximately 447ppi and up to a 120Hz refresh rate.

The display reaches a peak brightness of 3,200 nits covering 25% of the display area, helping maintain visibility in bright environments. It also supports a 480Hz touch sampling rate and up to 2,560Hz instantaneous touch sampling in Game Turbo mode.

The panel supports HDR10+ and Dolby Vision, DCI-P3 colour gamut, 12-bit colour depth and up to 3,840Hz PWM dimming. It is protected by Corning Gorilla Glass 7i.

MediaTek Dimensity 8400-Ultra Performance

The Xiaomi 15T is powered by the MediaTek Dimensity 8400-Ultra, manufactured using a 4nm process.

Its CPU configuration consists of one Arm Cortex-A725 core reaching up to 3.25GHz, three Cortex-A725 cores up to 3.0GHz and four Cortex-A725 cores up to 2.1GHz. Graphics are handled by the Mali-G720 GPU, while an NPU 880 provides AI processing capabilities.

The processor is paired with 12GB LPDDR5X RAM and 512GB UFS 4.1 storage, providing fast memory and storage performance for demanding applications, multitasking and large media libraries.

5500mAh Battery with 67W HyperCharge

The Xiaomi 15T incorporates a 5500mAh typical-capacity Xiaomi Surge battery.

It supports 67W HyperCharge, providing fast wired charging when used with a compatible Xiaomi charger. Xiaomi also states that the battery is designed to retain at least 80% of its capacity after 1,600 charging cycles under specified laboratory conditions.

Xiaomi HyperOS

The Xiaomi 15T launched with Xiaomi HyperOS 2, while Xiaomi has announced HyperOS 3 availability for the device through an OTA update, with rollout timing dependent on region.

HyperOS provides the software environment for the phone's applications, connectivity features and Xiaomi ecosystem functions. Supported Xiaomi HyperAI features include AI Writing, AI Speech Recognition, AI Interpreter, AI Search and AI Dynamic Wallpapers, although availability varies by region and language.

5G and Advanced Connectivity

The Xiaomi 15T supports 5G connectivity and Dual SIM configurations.

Depending on the region and carrier, the phone supports combinations of physical Nano SIM and eSIM. It also features Wi-Fi 6E, Bluetooth 6.0, NFC and an IR blaster.

The wide network-band support makes the Xiaomi 15T suitable for use across multiple markets, although actual 5G availability depends on the user's network operator and location.

IP68 Water and Dust Resistance

The Xiaomi 15T carries an IP68 rating for dust and water resistance under specified laboratory conditions.

Xiaomi states that the device was tested for resistance to static freshwater immersion up to 3 metres for up to 30 minutes under specified conditions. This rating should not be interpreted as making the phone completely waterproof, and Xiaomi advises against deliberately exposing it to water.

Premium Slim Design

The Xiaomi 15T measures approximately 163.2 × 78.0 × 7.5mm and weighs about 194g.

Its rounded body and slim profile provide a comfortable grip while maintaining space for the large display, battery and advanced camera system.
