iPhone 17 Pro Max Are you disappointed with Aluminum

Back then, the chips were not hot. The A4 for example, was about 1W. Today, the power consumption of A18 is an order of magnitude larger.

Apple started using foil sheets, then upgraded to graphene sheets to spread the heat, and now to vapor chamber.

Titanium has very poor thermal conductivity, it's like insulation. Aluminum was always the best choice. Most heatsinks are aluminum. Apple has decades of experience and a huge investment in carving aluminum unibodies. iPhone 15 Pro was an anomaly.

This. People don’t understand the difference in metals behind titanium being cool. Which it is. But it’s not the best in every application — and for a phone alum provides more ups than downs.

Yes it's surprising how bad titanium is as a thermal conductor. So this iPhone Air may throttle a lot. It's always something.....
