Apple hid a cooling secret inside the iPhone Duo’s hinge, and it could keep your foldable from overheating

A foldable phone gets twice as thick when closed, making it harder for heat to escape, and Apple's A20 Pro chip makes plenty of it. Apple moved the chip's memory beside the processor instead of on top, gave the phone a bigger vapor chamber, and threaded a bendable graphite pipe through the Duo's hinge so heat can travel between the two halves. The pipe was built with the hinge team so it survives years of folding.
