iPhone Ultra rumors point to a $2,399 price and a 5,800 mAh battery

Bloomberg reporter Mark Gurman says Apple's first foldable iPhone may land on Sept. 8, and the company is already testing software for a device that folds in half. He listed Sept. 9 as the backup date, with the foldable expected to debut alongside the iPhone 18 Pro and iPhone 18 Pro Max.

Reportedly, the code in the iOS 27 developer beta includes signs of a foldable device with multiple viewing angles, which suggests Apple is getting ready for a new form factor.

The hardware rumors point to a book-style foldable rather than a clamshell. The device is expected to feature a 7.8-inch main display, a 5.5-inch outer screen, and two rear cameras, while earlier problems with the 3D-printed hinge module are said to have been resolved and the phone has entered test production.

Battery life may be one of the biggest talking points. Supply-chain reports say Apple is testing batteries ranging from 5,400 to 5,800 mAh, and the top end would be the highest-capacity battery ever used in an iPhone if it makes it into the final model.

The leak roundup also says Apple's foldable may skip Face ID entirely. Instead, it is rumored to rely on Touch ID built into the lock button, while price estimates start at $2,000 and go as high as $2,399. Apple is also reportedly preparing around 10 million units, though some reports say the on-sale date could slip to late 2026 or early 2027.

Would Apple's first foldable feel worth it if it launched near $2,399 and used Touch ID instead of Face ID?
