The upcoming foldable iPhone could have the biggest battery ever in an iPhone, according to leaker “yeux1122“.

He says the tech giant is is testing a battery in the 5,400–5,800 mAh range. For comparison, the iPhone 17 Pro Max has a 5,088 mAh battery.

° It will feature a 24MP under-display selfie camera on the inner screen.

° It will include another 24MP selfie sensor on the cover display. 

° It might come with only two rear-facing cameras: a 48MP primary sensor and a 48MP ultra-wide sensor.

° Touch ID returns as a side button, as Face ID may be absent due to thickness and internal space constraints.

° The foldable iPhone will have a book-style design, featuring an approximately 7.8-inch crease-free inner display and an approximately 5.5-inch outer display.

° The rear camera features a dual-lens setup, with one front-facing camera available in both folded and unfolded states.

° It will measure 9–9.5mm thick when folded and 4.5–4.8mm when unfolded.

° The hinge will combine stainless steel and titanium alloy, while the casing opts for titanium alloy.

° It will use the same high-density battery cells as the ultra-thin iPhone 17.
