Apple preps a fast and furious iPhone 17 Pro Max with extra cooling

Currently, Apple uses a combination of hardware and software cooling, such as heat dissipating graphite sheets, processor clock frequency throttling under continuous pressure, lowering the display brightness, and even shutting down the phone’s operation if needed.

Vapor chambers work on the heat pipe principle, providing a flat vacuum sealed enclosure with a small amount of fluid inside. When heat comes in contact with the finned sink attached to it, the fluid evaporates to condense in cooler areas, absorbing the heat. It then gets wicked back to the heat source in a never-ending cycle, keeping the system running in a more stable manner with less thermal throttling.
