Apple’s 2026 iPhone Fold to Boast Largest Battery in iPhone History, Surpassing Galaxy Z Fold Series

The foldable iPhone’s battery is rumored to be significantly larger than that of Samsung’s Galaxy Z Fold 7 and possibly the upcoming Z Fold 8. Reports suggest the iPhone foldable battery capacity could range between 5,400mAh and 5,800mAh, which surpasses the Z Fold 7’s 4,400mAh and even exceeds the expected over 5,000mAh battery of the Z Fold 8. This larger battery could provide longer usage times during multitasking and video playback, addressing the high power demands of foldable displays

Battery Capacity Comparison

- iPhone Fold rumored battery: 5,400mAh to 5,800mAh

- Samsung Galaxy Z Fold 7 battery: around 4,400mAh

- Samsung Galaxy Z Fold 8 battery: likely just over 5,000mAh

- Other foldables like OnePlus Open and Pixel Fold have batteries around 4,800mAh

Apple’s approach to the foldable iPhone battery involves potentially housing dual battery cells inside the device, correlating with its size roughly comparable to two iPhone Air models side by side. This design likely favors battery capacity over ultra-thinness, which could enhance overall runtime and user experience in power-intensive foldable use cases.

Additional Features and Design Insights

Besides the impressive battery, the iPhone Fold is expected to feature advanced technology such as a crease-free 7.8-inch inner OLED display, a durable titanium-aluminum hybrid body, and a dual-screen configuration with a 5.5-inch outer display for convenient tasks. It will likely incorporate Apple’s latest A20 chip and newer modem technology, pushing foldable smartphone innovation further
