Xiaomi 15T Pro Review: Dimensity 9400+ Power Meets Leica Imaging

Have you ever thought that a smartphone could bring surprises in performance, imaging, battery life, and even communication without a network? The debut of the Xiaomi 15T Pro seems to be trying to give a definite answer. As the only flagship model in the Xiaomi 15 series equipped with a Dimensity chip, it not only packs powerful hardware configurations but also, through in-depth cooperation with Leica, takes mobile imaging experience to a new level. More importantly, it has made many optimizations in some “invisible” details, such as heat dissipation, endurance, and cross-device interconnection—these are often the key aspects that most affect the user experience in daily use.

Let’s first look at the most core part—performance. The Xiaomi 15T Pro is powered by the Dimensity 9400+ processor, based on TSMC’s 3nm process technology. The CPU adopts an architecture combination of one 3.7GHz Cortex-X925 ultra-large core, three Cortex-X4 large cores, and four Cortex-A720 efficiency cores. Judging from the parameters alone, this already belongs to the top level of the Android camp. The actual benchmark score reaches 1.56 million. What does that mean? Compared with Samsung and OPPO models at the same price point, which generally perform around 1.3 million, it leads by nearly 20%, making multitasking or high frame-rate gaming more effortless.

In terms of graphics performance, the GPU core scale integrated in the Dimensity 9400+ has also been significantly enhanced compared with the previous generation. In high-load games such as Genshin Impact, the Xiaomi 15T Pro can maintain nearly full-frame operation. Combined with the Ring Cold Pump 3.0 cooling system, even after 30 minutes of continuous gaming, the body temperature is about 5°C lower than that of the previous generation. This improvement is highly perceptible to gamers—no more worries about the phone turning into a “hot potato.”

Imaging has always been a key focus of Xiaomi’s flagship lineup. This time, the 15T Pro features a Leica professional triple camera system, including a 50MP main camera (Light and Shadow Hunter 900 sensor, with a 18% larger light-sensitive area than the previous generation), a 50MP telephoto lens (JN5 sensor, supporting 5x optical zoom and 20x hybrid zoom), and a 13MP ultra-wide-angle lens. Particularly noteworthy is its telephoto performance—at the 5x focal length, detail retention is excellent, color reproduction is true-to-life, and even under extremely low-light conditions, algorithms can still achieve usable shots. From actual sample photos, its tonal style carries a touch of “German flavor,” with moderate contrast and well-controlled highlights, easily capturing photos with a strong storytelling feel.

In video, both the main and telephoto cameras support 4K 60fps recording. Combined with HyperOS’s system-level stabilization and noise reduction algorithms, the dynamic capture success rate is much higher. Notably, through the newly added “One-Shot Transfer” function, the Xiaomi 15T Pro can quickly transfer photos and files to nearby Apple devices, making cross-platform sharing extremely convenient—very user-friendly for multi-device users.

In terms of battery and charging, the Xiaomi 15T Pro is equipped with a 5500mAh high-energy-density battery, offering up to one and a half days of normal use—an obvious improvement over its predecessor. For charging, it supports 90W wired fast charging (charger sold separately), providing very efficient top-ups—just the amount of time you spend washing up in the morning is enough to charge for half a day’s use.

In addition, several innovative features also add extra value to this product. For example, the off-grid communication technology supports point-to-point file transfer within 200 meters, allowing original image sharing even in no-signal environments; the satellite SMS function can send short messages via satellite when there is no ground network, which is very practical for outdoor enthusiasts or emergency situations. The display features a 6.83-inch flexible screen with 1.5K resolution, a local peak brightness of up to 3200 nits, and supports a 1–144Hz adaptive refresh rate—achieving a perfect balance between smoothness and power efficiency.

On the system level, HyperOS 3.0 further enhances fluency, animation, and interconnection experience, especially strengthening AI-related preprocessing capabilities. For example, 0.2 seconds before pressing the shutter, the AI algorithm has already begun RAW-domain noise reduction, greatly improving night photo success rates. Meanwhile, the phone can also be used as an external camera for tablets, enabling cross-device collaborative shooting and expanding creative possibilities.

Overall, the Xiaomi 15T Pro does not blindly pursue flashy specifications but delivers solid improvements in multiple dimensions such as performance, imaging, battery life, and communication. It may not be the cheapest flagship, but it is indeed a sincere creation with a well-balanced overall experience—especially suitable for users with higher demands on smartphones. If you’re looking for a device with outstanding imaging, powerful performance, and the ability to handle extreme communication scenarios occasionally, it’s definitely worth your serious consideration.
