Xiaomi (小米) Notebook Pro 14 packs 72Wh battery and ships with 100W GaN adapter — up to 19.8 hours claimed

Big battery, fast charging

Xiaomi (小米) has reportedly equipped its new Notebook Pro 14 with a 72Wh battery and says energy density reaches 800 Wh/L. IT Home (IT之家) reports the company claims up to 19.8 hours of battery life — including 12.4 hours of continuous video playback and 15.8 hours of online meetings — and that the laptop ships standard with a 100W gallium nitride (GaN) power adapter for “rapid top‑ups.” These figures have been published by the vendor and should be read as manufacturer claims.

Design and thermals

The Notebook Pro 14 uses a one‑piece die‑cast magnesium alloy body with a velvet finish, a titanium alloy keyboard support plate, a high‑strength carbon‑fiber bottom cover and graphene‑aluminum cooling fins, all aimed at lowering weight while improving heat dissipation. Xiaomi says the machine weighs just 1.08 kg and will be offered in Mist Blue, White and Elegant Gray finishes.

Performance and cooling

On the performance side, the top configuration reportedly includes Intel’s latest Core Ultra X7 358H processor, paired with a large 10,000 mm² vapor chamber, high‑speed quiet fans and a three‑channel cooling layout to enable sustained performance up to 50W. For Western readers: Intel’s Core Ultra line is the company’s newer mobile branding intended to compete with ARM‑based efficiency and AMD’s mobile chips in thin‑and‑light laptops.

Market context

Xiaomi is best known globally for smartphones and smart‑home gadgets; its laptop push is part of a broader strategy to extend the brand into premium PC hardware. Amid ongoing global supply‑chain tensions and U.S. export controls on advanced semiconductors, Chinese PC makers continue to rely on Intel and other international suppliers for high‑performance mobile CPUs. Can a big battery plus 100W GaN charging shift buyer priorities toward endurance and thinness? Xiaomi is betting it will.
