Wide foldables promise tablet-like workspace in a pocket, but fitting a large battery around dual display sections and a hinge remains one of the category’s central compromises. Xiaomi may be pushing that balance further with the Xiaomi 18 Fold: a leak attributed to tipster Bald Panda claims the device will use a 6,000mAh battery, alongside 67W wired charging and 50W wireless charging.
A capacity advantage, if the leak holds
The claimed 6,000mAh capacity would be notably large for a book-style foldable. For comparison, the Samsung Galaxy Z Fold8 has a 4,800mAh battery, while the Huawei Pura X Max is listed with a 5,300mAh cell. Battery capacity alone cannot establish real-world endurance, since display behavior, processor efficiency, and software optimization also matter, but Xiaomi would have a larger starting reserve if the reported specification is accurate.
The 50W wireless-charging claim is especially notable for a device expected to make room for a large internal folding panel. The reported 67W wired figure is more restrained by comparison, though neither charging rating nor the battery capacity has been confirmed by Xiaomi.

What Xiaomi has confirmed
Xiaomi has officially confirmed that the 18 Fold will use its 3nm Xring O3 processor and LPDDR6 memory supplied by CXMT. Other details circulating in earlier reports—including an approximately 7.6-inch folding display, a 200MP main camera, and a wide-format design shown in purported images—remain unconfirmed.
The Xiaomi 18 Fold is scheduled to debut in China in September 2026. There is no confirmed U.S. availability, pricing, or launch timeline. If Xiaomi validates the battery and charging claims, the device could stand out among large-screen foldables for users who prioritize longer untethered use over the usual capacity constraints of the category.
