Overview

• Apple’s four‑phone iPhone 17 lineup hits stores on September 19 with preorders underway, as early tests call the Pro Max the best battery performer reviewers have measured.
• The Pro and Pro Max adopt an aluminum unibody with a full‑width camera plateau and integrate a laser‑welded vapor‑chamber cooling system to sustain performance and spread heat more evenly.
• Camera upgrades on the Pro models include three 48MP sensors and a new 4x telephoto that reviewers say delivers sharper zoom with credible 8x results in good light, though low‑light 8x images show more noise.
• Real‑world battery testing reported by the Wall Street Journal found end‑of‑day charge remaining at roughly 54% on Pro Max, 30% on Pro, 27% on iPhone 17, and 19% on iPhone Air.
• The ultra‑thin iPhone Air draws notice for its 5.6mm design and A19 Pro silicon but trades away an ultrawide and telephoto camera and delivers shorter battery life compared with the Pros, according to reviews.
