Xiaomi 18 Fold to Get a 6,000mAh Battery With Fast Charging

According to a Weibo tipster (@pandverybald), the soon-to-be-announced Xiaomi 18 Fold might also get a 6,000mAh battery. The tipster didn't provide more details about the battery, but said the foldable would get 67W wired charging and 50W wireless charging. This is a noticeable hike in battery capacity over the previous Xiaomi Mix Fold 4, which had a 5,100mAh battery. Charging speeds remain the same as with the previous foldable.

The same source also revealed that the smartphone might feature Xiaomi's Xring O3 processor. Xiaomi recently confirmed that its upcoming 18 Fold foldable and flagship tablet, the Pad 9 Pro Max, will run on its new Xring O3 processor. At an event held in China, the company showcased the successor to the Xring O1. It also revealed that its new processor managed an AnTuTu score of 52,28,014 points. The chipset will have a deca-core layout with a maximum clock speed of 4.35GHz using its C1-Premium core.

Battery and processor aside, the Xiaomi 18 Fold will have a brand-new design. Its design moves away from the taller book-style form factor to a wider format for both its cover display and its main folding display. A recent report revealed the unannounced foldable's new design, showing a wide, visor-like rear camera module with three cameras. The leak also gave us a glimpse of its wide cover display and the new red finish.

Previously leaked specifications include a 6.56-inch cover display and a 7.76-inch inner folding display. Both displays might feature LTPO technology with an adaptive 120Hz refresh rate. The main camera is reported to pack a 200-megapixel sensor, while the remaining two are said to be telephoto cameras. Thanks to a new hinge design, the device might also offer IP68 dust and water resistance.
