iPhone 18 Pro Unveiled: Variable-Aperture Camera, A20 Pro Chip, and Extended Battery Life

Apple officially unveiled the iPhone 18 Pro and iPhone 18 Pro Max on September 9 at its Cupertino event, marking the first major iPhone launch under new CEO John Ternus. In India, the iPhone 18 Pro starts at Rs. 1,64,900, while the Pro Max starts at Rs. 1,79,900. Apple’s first foldable model, the iPhone Duo, is priced at Rs. 2,99,900. Pre-orders open on September 12, with sales beginning September 18.

Variable-Aperture Camera Leads the Upgrades

The biggest change is in the camera. The iPhone 18 Pro features a 48MP Fusion main camera with a mechanical variable aperture — a first for any iPhone. Six laser-cut blades adjust automatically or through four manual stops, opening as wide as f/1.48 for low-light shots. A new Pro Controls panel lets users manually adjust shutter speed, white balance, and aperture, along with an on-screen histogram.

A20 Pro Chip and Battery Life

The phone runs on Apple’s A20 Pro chip, built on a 2-nanometre process, delivering significant speed and efficiency gains. Battery life also improves, with the Pro Max offering up to 43 hours of video playback — the longest on any iPhone to date.
