A timeline of foldable iPhone rumors. Reports suggest an announcement on 9 September, possible pre-orders from 12 September and a launch in Japan several months later. The device is said to feature a 7.8-inch inner display and a 5.5-inch outer display, with efforts reportedly focused on making it thinner and improving thermal design.
This roundup of rumors based on MacRumors lists “Ultra” and “iPhone Duo” among the possible names for the foldable iPhone. “Ultra” is often cited as the internal name, but the official name has not been decided. Some reports point to an announcement on 9 September, with the launch either afterward or around the same time. At present, the only confirmed information is the date of the event. Production of the required components is facing difficulties, with reports of several hundred units being produced per day as of late August. Apple is conducting repeated validation to ensure that the device meets its quality standards. The launch timing by region, including Japan, may be 2–3 months after the US launch.
Balancing a thinner design with the inclusion of the necessary features is a key focus. The display is said to measure approximately 7.8 inches when unfolded and 5.5 inches when folded, while the exterior is expected to be slightly smaller than an iPad mini. Reports also describe a rear-camera design in which the camera bump ends partway along the back. Internally, Apple is considering an A20 chip, C2 modem and one of its largest battery configurations, using 2 cells. Reports indicate that Apple has moved toward including MagSafe, and references to foldState and other elements that return the folded state have been found in iOS 27.
