Report: Likely iPhone Ultra Battery Capacity Now Known | News

It is an open secret that Apple is working on a foldable smartphone. Many details of the new device type have already been leaked, from the aspect ratio of the internal display to the hinge to the likely camera equipment. It was previously unclear how much capacity the integrated energy storage would contain. The Weibo account “Digital Chat Station” now claims to have found out exact details. A battery manufacturer that usually produces components for Apple has registered two new models. They would be too small for an Apple smartphone, but together they have a capacity that would be suitable for an Apple foldable.

There is a component with 1,921 mAh and another with 2,962 mAh. In total this would be 4,883 mAh. This capacity is significantly higher than that of the Samsung Galaxy Z Fold 7, but lower than that of the Google Pixel 10 Pro Fold. This means that the iPhone Ultra would be almost on par with the current flagship, the iPhone 17 Pro Max, in terms of nominal energy reserves.

Battery capacities of current smartphones

Model	Capacity (mAh)
iPhone 17e	4,005
iPhone 17	3,692
iPhone Air	3,149
iPhone 17 Pro	3,988
iPhone 17 Pro Max	4,823
iPhone Ultra	4,883*
Galaxy Z Fold 7	4,400
Pixel 10 Pro Fold	5,015

Capacity is only part of the equation
The pure capacity of the installed energy storage is only one factor that influences the actual running time of the device. The screen usually accounts for a large proportion of energy consumption – the bigger, the more. In everyday life, the actual endurance of a battery charge is also determined by how often the iPhone Ultra is operated using the 7.8-inch foldable display when unfolded, and when users make do with the 5.5-inch touchscreen on the front.

Trimmed for efficiency
When developing the Ultra, Apple is said to have paid particular attention to optimizing components and systems for resource-saving operation. This also fits the rumor that the in-house mobile phone chip C2 is used in some regions. The Apple C1(x) has proven to be comparatively energy efficient in tests. However, Apple is unlikely to save on computing power: the iPhone Ultra will receive the regular A20 chip.
