Overview

• Pre-production photos shared by leaker Majin Bu show a micro-perforated copper base plate for a vapor chamber inside iPhone 17 Pro prototypes
• The phase-change system evaporates liquid in a sealed metal plate and moves heat to cooler areas before condensation and recirculation
• This will be Apple’s first dedicated thermal management solution for an iPhone, aligning its flagship with high-end Android devices
• Analysts expect the chamber to reduce thermal throttling, keep the A19 Pro chip cooler under heavy loads and extend battery life
• Apple is also reportedly testing lighter aluminum chassis materials to improve heat dissipation through the phone’s frame
