New rumors suggest the iPhone 18 Pro Max will offer more significant advantages over the standard iPhone 18 Pro this year, particularly in battery life. Leaked regulatory filings indicate the Pro Max model will feature a 5567mAh battery, a roughly 10% increase over its predecessor and a substantial jump from the 4288mAh battery expected for the iPhone 18 Pro.

While both new models are anticipated to benefit from efficiency gains from the A20 Pro chip and C2 modem, the Pro Max will boast a notably larger battery capacity. This increased battery size may result in a slightly heavier device. Additionally, there's speculation that a new variable aperture camera system could be exclusive to the Pro Max model, though this remains unconfirmed by multiple sources.

Historically, Apple has maintained consistency between its Pro models, with the Pro Max typically offering a larger screen and longer battery life, occasionally with an exclusive camera feature. This year appears to continue that trend, with battery capacity emerging as a significant differentiator.
