Powering the Xiaomi 15T may be a MediaTek Dimensity 8400 Ultra chipset. The SoC was introduced with the Poco X7 Pro 5G in January 2025. The handset is expected to run on HyperOS.

The tipster also claims that the Xiaomi 15T will pack a 5,500mAh battery. It may support fast charging at 67W.

On Geekbench AI's single-precision and half-precision tests, it scored 1,336 and 1,356 points, respectively. It also scored 1,974 points on the quantised test. The Xiaomi 15T was listed with Android 15 and 12GB of RAM.

As per reports, the Xiaomi 15T could be priced at EUR 649 (roughly Rs. 66,000). It is said to be offered in a single variant with 12GB of RAM and 256GB of onboard storage. Both the Xiaomi 15T and Xiaomi 15T Pro are reported to come with similar specifications, apart from charging speed and chipset.
