A new leak has allegedly revealed battery size details for the iPhone Ultra, a rumored foldable device from Apple [1].
These specifications are significant because they provide the first glimpse into how Apple intends to manage power in a foldable form factor. If verified, the battery capacity will determine whether the device can compete with existing foldables in terms of endurance and weight.
According to reports published July 10, the leak focuses specifically on the size of the battery intended for the Ultra model [1]. This device is expected to be part of a limited lineup for the year, with some reports suggesting only three iPhone models will be released in 2026 [2].
The timing of the leak comes as the industry anticipates an official announcement in September [1, 2]. This cycle of early disclosures has become a hallmark of Apple's product launches, often stripping away the surprise of the official event.
Mark Gurman said, "Apple leaks have sucked all the fun out of iPhone season" [3].
While the iPhone Ultra is the focus of current foldable rumors, other leaks have detailed different models in the upcoming lineup. For instance, previous reports indicated the iPhone 17 Air would be 9.5mm thick when including the camera bump [4].
Apple has not officially confirmed the existence of the iPhone Ultra or its specific battery specifications. The company typically maintains strict secrecy regarding hardware details until the products are unveiled on stage.
“Apple leaks have sucked all the fun out of iPhone season”
The emergence of battery specifications for a foldable 'Ultra' model suggests Apple is moving closer to a hardware pivot. By targeting a high-end foldable segment, Apple seeks to capture the premium market currently held by competitors, though the success of the device will depend on balancing battery life with the structural constraints of a folding screen.
