Apple’s Foldable Ambitions: New Battery Specs Hint at a 5,000 mAh iPhone Ultra
The long-rumored entry of Apple into the foldable smartphone market is gaining significant momentum. Recent leaks originating from the well-known tipster Digital Chat Station on Weibo suggest that Apple’s supply chain is already preparing the hardware necessary for a dual-cell battery configuration-a design choice standard for foldable devices to balance weight and power distribution across two halves of a folding chassis.
Decoding the Power Specs
The certification data reveals two distinct battery units with rated capacities of 1,921 mAh and 2,962 mAh. When combined, these provide a total rated capacity of 4,883 mAh. In the smartphone industry, manufacturers typically market the “typical” capacity, which rounds this figure up to a clean 5,000 mAh.
This capacity is a critical milestone for the upcoming iPhone Ultra. By hitting the 5,000 mAh mark, Apple is positioning its foldable device to compete directly with the endurance levels of current flagship powerhouses, ensuring that the power-hungry internal displays of a foldable don’t compromise daily usability.
Competitive Landscape: Apple vs. Samsung
The race for foldable dominance is heating up, and the iPhone Ultra is being measured against the industry standard-bearer, Samsung. Interestingly, these leaked specs place the iPhone Ultra in direct competition with the rumored Samsung Galaxy Z Fold8 Ultra.
While the Galaxy Z Fold8 is currently projected to feature a 4,800 mAh battery, Apple’s slightly larger capacity could provide a necessary edge, especially considering the optimization differences between iOS and Android. For context, as foldable technology matures, manufacturers are moving away from the sub-4,500 mAh batteries that plagued early-generation foldables, recognizing that users demand all-day battery life regardless of the device’s form factor.
Launch Timeline and Expectations
Despite a flurry of conflicting reports over the past year suggesting potential production bottlenecks or design delays, the latest industry intelligence indicates that the iPhone Ultra remains on track for a September release.
Apple is expected to unveil this groundbreaking device alongside the standard flagship lineup, including the iPhone 18 Pro and the iPhone 18 Pro Max. By launching the foldable alongside its traditional high-end models, Apple is signaling that the “Ultra” is not merely an experimental prototype, but a core pillar of its future hardware strategy.
As we approach the autumn launch window, the focus will likely shift toward how Apple plans to integrate its software ecosystem with the unique folding display, a challenge that has historically been the primary hurdle for foldable adoption. With a 5,000 mAh battery likely under the hood, the hardware foundation for a successful launch is finally falling into place.
