iPhone 18 Pro: Variable Aperture & Bigger Battery Rumored

Apple is anticipated to introduce notable enhancements with the iPhone 18 Pro and 18 Pro Max, potentially launching them as the sole flagships this fall. A key rumored feature is a variable aperture camera, which would allow users to adjust the aperture from f/1.78 to settings like f/4.0 or f/8.0 for creative photographic effects, a first for an iPhone. Manual camera controls are hoped for alongside this feature.

The iPhone 18 Pro Max is expected to boast a significantly larger battery capacity. U.S. versions are rumored to feature a 5,425 mAh battery due to eSIM, while international models with physical SIM trays may have a 5,235 mAh capacity. This represents a considerable increase from the iPhone 17 Pro Max's battery sizes.

Leaks also suggest a shrinking Dynamic Island, with Face ID components moving under the display. This evolution would reduce the physical cutout, offering more screen real estate. The A20 Pro chip, built on a 2nm process, is expected to deliver substantial performance and power efficiency gains, further enhanced by a new vapor chamber cooling design.

New color options are also anticipated, with rumors pointing to "Dark Cherry," "Light Blue," and "Silver-Gray." These models are being compared to historically memorable iPhones like the original iPhone, iPhone 4, iPhone X, iPhone 6 Plus, and iPhone 11 Pro, all of which introduced significant innovations.
