Apple’s first foldable iPhone expected as early as 2026 could ship with what might be the largest battery ever seen in an iPhone. Leaks originating from a Korean-language blog (via a user called yeux1122) suggest Apple is testing batteries in the 5,400–5,800 mAh range. To put that in perspective, the current iPhone 17 Pro Max uses a 5,088 mAh battery.
Why This Matters for Apple
Tackling Foldable Power Demands
Foldable devices naturally require more energy: they often have dual displays (inner and outer), which can drain power quickly. Apple seems aware of this challenge and is reportedly addressing it head-on. By using high-density battery cells and reengineering internal components, Apple aims to boost capacity without adding excessive bulk.
Efficiency & Design Trade-Offs
To maintain a slim form factor, Apple is said to be shrinking certain internal parts, including the display driver IC, from 28nm down to 16nm, a move that could help improve power efficiency. At the same time, this strategy may let Apple preserve battery life without compromising on the sleek, foldable design.
How It Compares to the Competition
If Apple’s testing numbers hold up, its foldable iPhone could surpass many current foldables on the market:
- Google’s Pixel Fold reportedly has a ~5,015 mAh battery.
- Samsung’s Galaxy Z Fold 7 is rumored to use a 4,400 mAh battery.
With a capacity between 5,400 and 5,800 mAh, Apple’s foldable could offer not only more power but potentially better endurance, especially if combined with its power-optimization efforts.
Other Key Specs: What We Know So Far
Beyond the battery leaks, additional reports outline several other features that might define Apple’s foldable iPhone:
- Display: Expected to be a “book-style” foldable with a ~7.8-inch main screen when opened and a ~5.5-inch cover display.
- Cameras: Leaks suggest a four-camera setup including an under-display front camera for the inner screen.
- Authentication: Instead of Face ID, Apple may use Touch ID on the side button, possibly to save space internally.
- Cellular: The foldable is expected to use Apple’s second-gen C2 modem, which supports high-speed 5G.
- Build & Efficiency: Rumors suggest Apple is pushing for power gains by refining display components, making the device more energy efficient without overly thickening it.
Apple’s first foldable iPhone might not just fold, it could pack a record-setting battery, according to current rumors. If true, the 5,400–5,800 mAh range would make it the most power-packed iPhone ever, underscoring Apple’s effort to tackle the unique energy demands of a foldable device while maintaining efficiency and design elegance.
