iPhone Ultra Leaks With Actual Numbers: 4.5mm Thin, 5,800mAh Battery

Apple’s folding phone won’t be called the iPhone Fold. The name doing the rounds now is “iPhone Ultra” — a detail that surfaced from Digital Chat Station a few days back. Then came a leaked video from Jon Prosser of FPT, and suddenly, there’s a lot more to talk about.

Prosser didn’t just drop renders. He came with actual numbers. Unfolded, this thing measures 4.5mm thick. For context, the Galaxy Z Fold 7 sits at 4.2mm unfolded — so Apple’s not far off, arguably in the same conversation. Folded, it goes to 9.5mm, which is genuinely competitive for a device with two full display panels sandwiched together.

The renders themselves are a step up from those murky dummy unit photos that floated around earlier. Those didn’t tell you much. These do. The body is industrial metal, the camera arrangement runs horizontally across the back with two lenses, and the front display has a corner punch-hole cutout — same placement Oppo used on the original Find N back when that form factor was still figuring itself out. Wide aspect ratio, shorter than the Z Fold 7 in overall height. The closest visual comparison is actually Google’s original Pixel Fold, not Samsung’s lineup.

On battery — reports point to a 5,800mAh cell. The Z Fold 7 runs 4,400mAh. Even the Galaxy Z Tri Fold, which splits its battery across three sections to hit 5,600mAh, comes in just under. Apple apparently decided that if you’re building a large-format folding device, you put a large battery in it. Straightforward logic, not always followed.

The “Ultra” branding still feels odd for a folding phone; that name has lived on the high-end Pro Max tier for a while now. Whether Apple sticks with it through launch is another question entirely.
