First iPhone 18 Pro teardown shows larger battery and vapor chamber

AI-summarised brief · reviewed before publication

A short video teardown by REWA Technology reveals that Apple’s iPhone 18 Pro retains its overall design but introduces a larger vapor‑chamber cooler that now contacts the A20 Pro processor directly, improving thermal management. The battery is about 1.7 % larger than the iPhone 17 Pro, confirming modest capacity gains reported by Joanna Stern. The Dynamic Island has been narrowed, with the infrared camera cutout shifted to a screen corner, a change that may complicate aftermarket display repairs. The teardown also notes new materials and cable alterations, though Apple has not publicly detailed these. Repairability appears reduced, as the repositioned infrared sensor poses a new challenge for third‑party display manufacturers. The iPhone 18 Pro and Pro Max are already shipping to customers.

💡 Why It Matters

· Apple’s tighter integration of cooling and processor boosts sustained performance, while the slimmer Dynamic Island and tougher repair profile signal a shift toward higher‑end, less serviceable flagship devices.

iOS 27’s Wallet app adds feature that will make you want to…

Apple’s iOS 27 introduces a bill‑splitting feature that integrates Apple Cash with Apple Wallet, Messages, and the Camera app’s Siri mode.

The feature supports common tip percentages and works across multiple Apple interfaces, aiming to streamline post‑meal settlements. Adoption depends on users having Apple Cash set up, but the seamless workflow could boost its usage.

💡 By embedding bill splitting directly into core Apple apps, the update positions Apple Cash as a more convenient alternative to third‑party payment services, potentially reshaping everyday peer‑to‑peer transactions.
