According to a leaker, the iPhone 18 Pro Max is set to feature a larger battery for exceptional battery life. Digital Chat Station, a known source, claims the device will have a battery capacity between 5,100 and 5,200 mAh. Paired with improvements from the A20 Pro chip built on TSMC's 2nm process, the phone could offer impressive battery performance.

The current iPhone 17 Pro Max already boasts the largest iPhone battery at 5,088 mAh, providing up to 39 hours of battery life, according to Apple. Recent tests confirm Apple's lead in battery efficiency. Considering these factors, the iPhone 18 Pro Max could comfortably exceed 40 hours of use, making it a top contender in the market.

Simultaneously, the first foldable iPhone, expected to debut alongside the iPhone 18 Pro and Pro Max, is rumored to have class-leading battery life, potentially exceeding 5,500 mAh. This would establish it as the largest capacity of any iPhone or rival foldable device. The new phones are expected later this year.
