With the Xiaomi 15T Pro, Xiaomi finally sheds the reputation of the T models as budget compromises. The new device delivers a major surprise in testing–and suddenly ranks among the best smartphones of the year.
A new chip, an unusually strong endurance rating, and a significant performance leap make even established flagships look outdated. The test impressively shows why the 15T Pro makes a real statement in the smartphone world.
A T Model That Puts Flagships Under Pressure
Until now, Xiaomi’s T models were considered stripped-down versions of top smartphones. But the Xiaomi 15T Pro impresses with full performance. In the extensive lab test by COMPUTER BILD, it achieved a speed rating of 1.0 and competes with expensive flagships like the Xiaomi 15 Ultra or the Poco F7 Ultra. The new MediaTek processor is responsible for this.
The MediaTek Dimensity 9400+ in the Xiaomi 15T Pro, manufactured using the modern 3-nanometer process, is not only more energy-efficient but also noticeably faster than its predecessors. In benchmark tests, the 15T Pro achieves performance levels typically reached only by high-end models. The base model Xiaomi 15T also benefits from the technological leap with the Dimensity 8400 Ultra.
The MediaTek processor demonstrates that speed doesn’t necessarily mean Qualcomm. This is a remarkable step for Xiaomi and sets the 15T Pro apart from its predecessors.

Xiaomi 15T Pro with Long-Lasting Battery
Particularly impressive is that the high computing power does not come at the expense of battery life. In the standardized battery test, the Xiaomi 15T Pro lasted 15:01 hours. This is a significant improvement compared to the 14T Pro, which lasted 11:31 hours.
The 5500-mAh battery and the efficiency of the 3-nm chip together contribute to this long runtime. This allows the 15T Pro to even surpass the 15 Ultra, which lasted 13:24 hours. Despite the strong performance, the device remains remarkably energy-efficient.
