Apple’s first foldable may pack the biggest battery in the iPhone-verse. According to the latest leak, not just the battery, but Apple is also testing a different design layout for its button.
Apple’s long-rumoured iPhone Fold may finally be taking shape, and if new leaks are to be believed, it could arrive with a huge battery and a striking redesign.
Fresh rumours circulating on Chinese microblogging platform Weibo suggest that Apple is testing a 5,500mAh battery, the largest ever in an iPhone, along with several design tweaks tailored for a foldable form factor.
Apple, as usual, has not confirmed or commented on the speculation, but the steady drip of reports over recent months points to one of the company’s most ambitious hardware projects yet.
Apple iPhone Fold: Biggest iPhone battery yet
According to the new information, the 5,500mAh battery would mark a significant leap over Apple’s current flagship, the iPhone 17 Pro Max, which is expected to feature a 5,088mAh cell. The increase in capacity is unsurprising given the demands of foldable displays, which require more power to drive larger, dual-screen configurations.
The move would also address one of the biggest complaints about early foldable smartphones, poor battery life. By prioritising endurance, Apple seems to be positioning the Fold as a reliable daily driver rather than a novelty device.
Analysts note that the company has historically been conservative with battery upgrades, preferring to optimise efficiency through chip design and software. A larger battery therefore signals Apple’s recognition that foldable phones need more than software cleverness to compete in the premium segment.
iPhone Fold: Design changes and camera upgrades
The leaks also mention a revised button layout, with higher-profile volume controls relocated toward the top of the device. This adjustment could make the phone easier to use when unfolded, improving reachability and ergonomics, a consistent issue in existing foldables.
Other rumoured enhancements include updated camera hardware, a refined hinge mechanism, and improvements to the chassis that could boost durability. Apple is reportedly testing multiple hinge prototypes to reduce visible creasing and maintain balance when the device is half-open.
Although details remain under wraps, these iterative design choices suggest that Apple is applying its trademark attention to long-term usability, ensuring the Fold feels familiar to iPhone users while offering something distinctly new.
Apple has not officially acknowledged the
iPhone Fold project, but the frequency of component leaks, supplier reports, and patent filings paints a clear picture of active development. The company has historically waited for new form factors to mature before entering a category, a pattern seen with both the Apple Watch and AirPods.
If that strategy holds, Apple’s first foldable could arrive with fewer compromises than early rivals, offering stronger build quality, better optimisation, and the battery stamina foldable phones have long lacked.
