What Upgrading to iPhone 18 Pro From iPhone 17 Pro Gets You

The useful part

Apple's new iPhone 18 Pro and iPhone 18 Pro Max largely build on last year's models with a series of targeted upgrades rather than a major redesign. The most notable changes dial in better performance, camera capabilities, battery life, and wired charging speeds. The iPhone 18 Pro and Pro Max retain the same 6.3-inch and 6.9-inch display sizes, 3,000-nit peak outdoor brightness, and 48-megapixel Ultra Wide and Telephoto cameras with 4x Telephoto and 8x optical-quality zoom.

How it works

• The Main camera, however, receives substantial upgrades, including the new variable-aperture system.
• MagSafe and Qi2 charging also remain capped at 25W, while the overall industrial design â€" minus the Dynamic Island â€" is largely unchanged.
• A20 Pro chip replaces the A19 Pro, with up to 20% faster CPU and 40% faster GPU performance.
• Twice the AI processing performance, with a new Dual 16-core Neural Engine.
• Redesigned vapor chamber with three times the surface area, enabling up to 40% better sustained performance.

What to take from it

Smaller Dynamic Island that can display up to three Live Activities at once. Variable-aperture 48MP Main camera with Æ'/1.48, Æ'/1.8, Æ'/2.8, and Æ'/4 settings, replacing the fixed Æ'/1.78 aperture on the iPhone 17 Pro models. New manual camera controls for aperture, shutter speed, white balance, and histogram.
