Leak: iPhone 18 and iPhone 18e to share 4430mAh battery
A reported leak also tips both Apple models for a 6.3-inch display, with the iPhone 18e possibly switching from a notch to Dynamic Island.
A new leak reported by 9to5Mac suggests that Apple's iPhone 18 and iPhone 18e will both use a 4430mAh battery and adopt a 6.3-inch display, according to digitaltoday.co.kr. The same leak covers a third model, the iPhone Air 2.
The report says the iPhone 18e could grow to 6.3 inches and may move from a notch to Dynamic Island. The iPhone 18's main camera is said to shrink slightly in size while keeping its 48-megapixel resolution.
The ultra-wide camera is reported to remain exclusive to the iPhone 18 and may be omitted from the iPhone 18e, widening the gap between the two models on imaging.
The leak also mentions A20 chip efficiency improvements as something that could combine with the larger battery, but it did not include any A20 specifications.
Earlier expectations
