iPhone Ultra (Fold) Battery Specs Leaked, Dual Cell Design Possible
The general consensus is that Apple will unveil its first foldable iPhone at a launch event in September, and at that point, most of our questions will be answered.
This includes whether the device will be called the iPhone Ultra or iPhone Fold, or something else entirely. We're also hoping to get some official clarification on battery life, but in the meantime, a well-known leaker has shared some interesting design specs.
According to Weibo's Digital Chat Station, the iPhone Ultra (we'll call it that for now) will adopt a dual-cell battery design with each cell having a capacity of 1,921mAh and 2,962mAh respectively, totaling 4,883mAh. This is reportedly based on regulatory filings submitted by Apple's battery suppliers.
While this figure is slightly lower than some previous rumors had predicted, the leaker mentioned that it's likely a minimum capacity. The final capacity could be higher, and supply chain sources have claimed that the final capacity could exceed 5,000mAh.
For easy comparison with existing smartphone models (both regular and foldable designs), here are some figures:
• Motorola Razr Fold (2026): 6,000mAh
• Apple iPhone 17 Pro Max: 5,088mAh (eSIM only) / 4,823mAh (nano SIM)
• Google Pixel 10 Pro Fold: 5,015mAh
• Samsung Galaxy S26 Ultra: 5,000mAh
• Motorola Razr Ultra: 5,000mAh
• Samsung Galaxy Z Fold 7: 4,400mAh (rated capacity 4,272mAh)

A 4,883mAh dual-cell battery isn't exactly groundbreaking in the smartphone industry, foldable or otherwise. As another reference point, Apple's iPhone 18 Pro Max is rumored to have the largest battery ever seen on an iPhone, with eSIM-only models packing 5,425mAh and nano SIM models boasting 5,235mAh.
Another big question mark is the price. Past leaks and rumors suggest that the iPhone Ultra could cost over $2,000 depending on storage options, potentially ranging from $2,300 to $2,500. There are also whispers that the iPhone Ultra might be in short supply compared to the iPhone 18 series, which could make Apple's first foldable phone difficult to get your hands on.
Of course, none of this is official. We'll have to wait for Apple's launch event to confirm whether the dual-cell battery rumor and other leaked information are accurate.
