Foldable iPhone Said to Feature Massive 5,500mAh Battery

According to recent reports from supply chain leakers, Apple’s first foldable iPhone is being designed with a battery that could reach 5,500mAh, making it the largest battery ever put into an iPhone (via MacRumors).

To put that 5,500mAh figure in perspective, the current battery king in Apple’s lineup is the iPhone 17 Pro Max, which features a 5,088mAh cell. Most current foldables on the market struggle to even reach the 5,000mAh mark. The Samsung Galaxy Z Fold 7, for instance, relies on a 4,400mAh battery, and Google’s Pixel 10 Pro Fold sits at 5,015mAh.

By using high-density silicon-carbon battery technology, Apple can pack more power into a smaller physical footprint. This tech allows the phone to stay relatively thin, rumored to be just 4.5mm when unfolded, without sacrificing the “all-day” battery life users expect.

While the battery is the headline, the internal hardware is shaping up to be a powerhouse. The device is expected to run on the upcoming A20 chip, which is built on a 2nm process. This new chip isn’t just about speed; it is designed to be significantly more efficient, meaning it draws less power from that massive battery.

The design itself is expected to feature a 7.8-inch main display that is crease-free. Apple has reportedly been working on a liquid metal hinge and a custom display structure to ensure the middle of the screen looks perfectly flat when opened. On the outside, you’ll likely find a 5.5-inch cover screen for quick tasks.

Interestingly, some familiar features might be changing. Reports suggest Apple may skip Face ID for this model to save internal space, opting instead for a Touch ID sensor built into the side power button. It’s a move we’ve seen on the iPad Air, and it allows for a cleaner, notch-free display.
