Leaker Says iPhone Fold Battery Will Be Huge — Biggest Yet for an iPhone New leaks suggest that Apple’s first foldable iPhone — widely referred to as the iPhone Fold — could include the largest battery ever seen in an iPhone, potentially by a significant margin. The information comes from industry leakers and corroborating supply‑chain chatter published recently.
According to a well‑known Weibo leaker dubbed Fixed Focus Digital, the iPhone Fold may pack a battery of at least 5,500 mAh — and possibly even larger — once final production decisions are made. If accurate, that capacity would surpass the current record held by the iPhone 17 Pro Max (around 5,088 mAh) and likely top the next iPhone 18 lineup as well.
What’s more, multiple sources indicate Apple has been testing battery sizes in the ~5,400–5,800 mAh range for the foldable device, and some rumors even point toward near‑6,000 mAh cells. This would be especially notable because foldable phones typically have to balance power demands across two screens — the main interior display and a smaller exterior one — which tends to increase overall energy consumption.
By comparison with current foldable rivals on the market, this would give Apple a potential edge: the Google Pixel 10 Pro Fold reportedly has around 5,015 mAh, and the Samsung Galaxy Z Fold 7 has about 4,400 mAh. So a battery in the 5,500 mAh+ range could put the iPhone Fold at the forefront of foldable battery capacity if these rumors hold true.
The iPhone Fold is expected to launch alongside the iPhone 18 Pro and Pro Max later in 2026, with Apple positioning its first foldable as a premium device that rethinks internal component layout — including battery placement — to maximize endurance without compromising design.
Worth noting: None of this has been confirmed by Apple, and leaker claims should be treated with caution until official specs are announced. Nonetheless, the consistent reporting suggests that battery size is a major focus for Apple’s entry into the foldable phone market.
