Where Apple Focused Engineering so the iPhone Duo Could Have Desktop-Like Performance

The iPhone Duo’s cooling system hides a clever trick inside its hinge

While a folding iPhone posed a new challenge for Apple’s thermal engineering team, they came up with a creative way to leverage the device’s hinge to their advantage.

Apple's Hidden Thermal Mastery: How the iPhone Duo Achieves Laptop-Class Power in a Folding Frame

Apple just shipped its first foldable iPhone. The Duo, arriving in stores this week, carries a price tag near $2,000 and a design that bends in half. Yet the real story sits inside. Engineers spent years solving heat in a device thinner than any prior iPhone when open. Their fixes let the A20 Pro chip sustain performance once reserved for MacBooks. The numbers sound familiar at first. Up to 20 percent faster CPU. Forty percent faster GPU. Double…

Where Apple focused engineering so the iPhone Duo could have desktop-like performance

To make the iPhone Duo as thin as it is, Apple needed to make a lot of design choices to fend off heat. Here's what they did, how they did it, and where in the device the innovations live.iPhone DuoFolding devices like the iPhone Duo often raise engineering challenges due to their unique design. However, solving problems like making as thin a smartphone as possible can lead to the creation of others, such as keeping it cool.In an interview with …

Exclusive: Apple Routed a Graphite Pipe Through the iPhone Duo’s Hinge. Here’s Why

The A20 Pro is Apple's most advanced mobile processor ever. I sat down with the silicon and thermal engineering teams at Apple to learn how custom technology keeps the chip cool, maximizing performance in the iPhone Duo and 18 Pro lines.

iPhone Duo Graphite Pipe in the Hinge Cools the A20 Pro

Apple routed a flexible graphite pipe through the iPhone Duo’s hinge to move heat between the phone’s two halves. Foldables face a cooling problem that slab phones do not, because the iPhone Duo doubles in thickness once it is closed.... Read more at iPhone Duo Cools the A20 Pro with a Graphite Pipe in the Hinge
