Under the hood, the MediaTek Dimensity 8400 Ultra processor could be powering the upcoming Xiaomi 15 series device. This falls in line with the previously spotted Geekbench listing of the Xiaomi 15T as well.

Fueling the device will be a 5,500mAh battery, paired with 67W fast charging support. The live image of the device also reveals that the phone will be using Leica's Summilux optical lens. This is the same lens that the Xiaomi 14 Ultra uses and is said to bring a wider aperture for more light and details.
Apart from this, nothing else is known about the device. However, with the Xiaomi 15T series global launch scheduled for September 24, 2025, we just have to wait around a week to know all the details.
