Record‑Breaking Battery Capacity
Fixed Focus Digital claims the upcoming iPhone Fold will be equipped with a 5500 mAh battery – the largest ever fitted inside an iPhone. This increase aims to offset the higher power draw of a dual‑screen design and to provide all‑day usage even when the device is constantly folding.
Unconventional Button Layout
According to the second leak, Apple plans to move the volume controls from the traditional left‑side location to the top‑right edge of the device, mirroring the iPad mini’s arrangement. The power button (integrated with Touch ID) and the AI/camera button will remain on the right side.
- Volume buttons: top‑right side
- Power/Touch ID button: right side
- AI (camera) button: right side
This shift is driven by internal architecture: the motherboard resides on the right, and relocating the volume controls eliminates the need to route wires across the screen to the left side.
Hinge and Ribbon‑Cable Engineering
The hinge is the most vulnerable part of any folding phone. Samsung’s experience shows that repeated folding can cause a cascade of failures. For the iPhone Fold, Apple must address two critical concerns:
- Ensuring the display can endure constant folding and unfolding without degradation.
- Reducing the number of ribbon cables that must cross the hinge, which are prone to wear and can affect reliability.
By placing the volume buttons on the top‑right, Apple hopes to minimize ribbon‑cable length and complexity, thereby improving the durability of the hinge mechanism.
