Apple’s long-anticipated iPhone Fold could pack a massive battery and bold design changes, according to fresh rumors on the Chinese microblogging platform Weibo. Leakers with a mixed but established track record shared the details, which 9to5Mac reported Monday.

A representative for Apple did not immediately respond to a request for comment.

Biggest iPhone battery yet

According to the latest report, Apple is testing a 5,500-mAh battery for the iPhone Fold. If accurate, that would make it the largest battery ever used in an iPhone by a significant margin. For comparison, the iPhone 17 Pro Max is expected to ship with a 5,088-mAh cell, already the biggest battery Apple has put in a nonfolding iPhone.

The jump in capacity makes sense given the demands of a foldable design, which typically requires more power to drive a larger internal display. It also suggests Apple may be prioritizing battery life as a key selling point, an area where early foldables from other manufacturers have often struggled.

Buttons, cameras and other design tweaks

Separate leaks point to additional hardware changes, including higher-profile volume buttons positioned toward the top of the device. The shift could improve usability when you unfold the phone, where traditional button placement can feel awkward.

The same report references updated camera hardware and refinements to the hinge and chassis, though specific details remain vague. Taken together, the changes hint at Apple continuing to iterate on ergonomics and durability — two areas where foldable phones face the most scrutiny.

While Apple has yet to publicly acknowledge the iPhone Fold, the growing volume of leaks suggests development is well underway. If these rumors hold, Apple’s first foldable could arrive with fewer compromises than earlier entries in the category.
