Leaks about the foldable iPhone have finally disclosed a battery that remains stable under pressure.
Foldable iPhone leak hints at the largest battery ever in an iPhone
For years, the idea of a foldable iPhone has been akin to the legend of Bigfoot – many claim to have seen hints of it, yet actual evidence has been limited. We’ve observed Samsung and Google improve their foldable devices with each iteration, while Apple has remained on the sidelines, likely waiting to perfect their approach. However, recent rumors from the supply chain suggest that Apple’s wait may be coming to an end, with plans to make a grand entrance featuring the largest battery ever seen in a foldable device.
A recent leak from a source known as “Fixed Focus Digital” indicates that Apple’s first foldable device – temporarily dubbed the “iPhone Fold” – could be a true powerhouse when it comes to battery life. The rumor claims it might offer a battery capacity greater than 5,500 mAh, which is considerably larger than the 5,088 mAh battery found in the impressive iPhone 17 Pro Max, not to mention surpassing key competitors like the Google Pixel 10 Pro Fold and Samsung’s Galaxy Z Fold 7.
Why battery size is crucial
This is significant because battery life has historically been a major weak point for foldable devices. The physics are straightforward: powering two separate screens – one tablet-sized – leads to rapid energy consumption. Manufacturers often end up dividing the battery into smaller, thinner cells to accommodate the folding design, which can result in unsatisfactory performance. If Apple has indeed managed to fit a 5,500 mAh cell into a compact chassis without making it feel bulky, they are not only catching up but also addressing the major concern in this product category.
The leak also reveals details beyond the battery capacity. The expected specifications include a 7.8-inch internal display that is said to be “crease-free” (the ultimate goal in foldable technology) and a 5.5-inch outer display. It is anticipated to be powered by next-generation A20 silicon paired with a new “C2” modem.
This combination is vital. Apple's chips are renowned for their efficiency. Combining a high-efficiency A20 chip with the largest battery ever seen in an iPhone could lead to a device that genuinely lasts all day, even with extensive multitasking, such as working on spreadsheets or editing videos on a large screen.
The strategy: prioritize quality over being first
For consumers, this shifts the perception of foldables from mere “novelty” devices to serious productivity tools. Content creators and business travelers have often avoided foldables due to concerns over battery life around mid-afternoon. If Apple can deliver exceptional endurance, this device could become the ultimate all-in-one machine.
The timeline suggests a potential launch in late 2026, likely alongside the iPhone 18 lineup. It appears Apple is adhering to its traditional strategy: waiting for technology to advance, observing competitors' early missteps, and then launching a refined product aimed at dominating the premium market. If these specifications are accurate, the “iPhone Fold” won’t just be Apple’s initial foray into flexible smartphones; it may very well be the first device that doesn’t require users to trade battery life for a larger screen.

Foldable iPhone leak suggests innovative engineering and a design reminiscent of the iPhone X
Apple's foldable iPhone may deviate from conventional hardware designs, rearranging buttons and cameras to optimize battery life and display area in what could be its most daring redesign yet.
The much-anticipated foldable iPhone is starting to appear more tangible, and if the latest leak is credible, it may come with a radical redesign for its physical buttons, camera arrangement, and internal configuration. Typically, volume controls are found on the left edge and the power button (with Touch ID) on the right side of a standard iPhone. However, on the iPhone Fold, the volume buttons might be located on the upper right side, similar to the layout seen on the iPad mini.
If Apple eliminates the 128GB option again, the iPhone 18 Pro could become significantly more expensive
Apple might be planning a classic pricing strategy that doesn’t appear to be a price increase at first glance. By altering the starting storage capacity, they can raise the cost for customers seeking their desired model. Last fall, Apple removed the 128GB iPhone 17 Pro model, forcing customers who wanted that Pro version to start with the 256GB option, which came with a $100 price increase.
