Xiaomi has launched the Redmi K100 in China, a phone built around battery life. According to the specifications the company published, it carries a 10,000mAh silicon-carbon battery with 100W fast charging. The starting price is 3,499 yuan (about $525), which places it in the mid-range segment rather than among top-tier flagships.

The K100 runs a Snapdragon 8 Elite, with up to 16GB of RAM and up to 512GB of UFS 4.1 storage. The screen is a 6.83-inch AMOLED with a 2,772 x 1,280 resolution, a 165Hz refresh rate and peak brightness of 3,500 nits. The rear has a dual camera with a 50MP main sensor and an 8MP ultrawide. The phone is IP69K-rated for dust and water resistance and supports Wi-Fi 7.

The comparison with rivals is the sharpest point of the launch. Samsung and Google remain on batteries of roughly 5,000-6,000mAh: the Galaxy S26 Ultra has a 5,000mAh Li-ion battery and the Pixel 11 Pro XL 5,115mAh, although both are phones costing thousands of dollars. The gap is stark, and the K100 is only the latest example of a trend Chinese brands have already pursued: the Redmi Note 17 Pro Max already brought a 9,210mAh silicon-carbon cell, and the Oppo A7 Pro Max has extended its 10,000mAh battery to new markets.

The K100 is not an isolated case within its own series either. Earlier leaks had pointed to it as the longest-lasting model in the family, with a 10,000mAh battery and a dedicated display chip, and the official launch confirms that line. The standard model follows the Redmi K100 Pro Max, aimed at gaming, and sits at a noticeably lower price.

There are no dates or prices for Europe. According to unconfirmed reports, the K100 could reach global markets as a POCO F-series phone, as happened with the earlier K90 and K80. These remain speculation, and for now the phone is available only in China.
