iQOO has introduced the Z11S, a mid-range smartphone that prioritizes battery longevity above all else.
It is the company's first device to pack a massive 10,000mAh battery, developed in collaboration with CATL.

The battery uses second-generation semi-solid technology and 'Magic Cube Packaging 2.0' to achieve high energy density.
Despite the large cell, the phone measures just 8.59mm thick and weighs 225 grams.
That's only 11 grams heavier than the Galaxy S26 Ultra, despite having double the battery capacity.
Charging is supported at 44W wired, which may not be the fastest but ensures the phone can last over two days on a full charge.

Under the hood, the Z11S is powered by the MediaTek Dimensity 7500 octa-core chip, built on TSMC's N4P process.
It features ARM's latest C1 cores and reportedly scores around 1.31 million on AnTuTu V11.
iQOO also promises a 24% improvement in single-core performance and five years of smooth usage.
The device sports a 6.83-inch AMOLED display with 2800 × 1260 resolution, 10-bit color, and a 144Hz refresh rate.
