For years, the concept of a foldable iPhone has felt a bit like Bigfoot – everyone claims to have seen signs of it, but actual proof has been scarce. We have watched Samsung and Google iterate on their foldables generation after generation, while Apple has sat on the sidelines, presumably waiting until they could get the formula exactly right. Well, if the latest whispers from the supply chain are to be believed, that wait might finally be nearing its end, and Apple isn’t just planning to join the party; they are planning to crash it with the biggest battery we have ever seen in a foldable.
According to a fresh leak from the tipster known as “Fixed Focus Digital,” Apple’s debut foldable – let’s call it the “iPhone Fold” for now – is shaping up to be a stamina monster. The rumor suggests the device could pack a battery capacity exceeding 5,500 mAh. To put that number in perspective, that is significantly larger than the battery in the powerhouse iPhone 17 Pro Max (rated at 5,088 mAh) and eclipses major rivals like the Google Pixel 10 Pro Fold and Samsung’s Galaxy Z Fold 7.
Why battery size is the real battlefield
This matters because, historically, battery life has been the Achilles’ heel of the foldable form factor. It is simple physics: when you have a device that needs to power two separate screens – one of which is tablet-sized – you burn through energy fast. Usually, manufacturers have to split the battery into two smaller, thinner cells to allow the device to fold, which often results in mediocre performance. If Apple has figured out a way to cram a 5,500 mAh cell into a chassis without making it feel like a brick, they aren’t just catching up; they are solving the biggest pain point of the category.
The leak doesn’t stop at the battery. We are looking at a reported 7.8-inch internal display that claims to be “crease-free” (the holy grail of foldable tech) and a manageable 5.5-inch outer screen. Under the hood, it is expected to run on the next-generation A20 silicon paired with a new “C2” modem.
This combination is crucial. Apple’s chips are already legendary for their efficiency. Pairing a hyper-efficient A20 chip with the largest battery ever put in an iPhone could result in a device that genuinely lasts all day, even with that massive screen lit up for multitasking, spreadsheets, or editing video on the go.
The strategy: better, not first
For the consumer, this shifts the foldable from a “cool toy” to a serious productivity tool. Content creators and business travelers have often shied away from foldables because they can’t afford to be tethered to a power outlet by 3 PM. If Apple delivers best-in-class endurance, this device becomes the ultimate “do-it-all” machine.
The timeline points to a late 2026 launch, likely alongside the iPhone 18 lineup. It seems Apple is sticking to its classic playbook: wait for the technology to mature, watch competitors make the early mistakes, and then release a polished product that dominates the high-end market. If these specs hold true, the “iPhone Fold” won’t just be Apple’s first flexible phone; it might be the first one that doesn’t ask you to compromise on battery life to get a bigger screen.
