Apple Says iPhone 15 Pro's Titanium Frame Does Not Contribute to Overheating Issue

[Tagbert]

While the titanium side frame part might be an alloy, it's bonded to the inner aluminum side frame.

Yes, and the inner chassis transfers heat to the outer frame.

It is actually a titanium alloy. Grade 5 titanium is mixed. Titanium is far superior for heat dissipation as well, over stainless steel. Top of the line car exhausts are titanium. I think we will see better battery health stats this year being tue titanium is dissipating the heat better.

Throwing in performance car exhaust is sort of a red herring in this discussion. It's great for racing primarily because titanium alloys weigh a fraction of equivalent steel. Ti alloys are also more thermally stable than steels. Ti alloys are also very corrosion resistant. Exhaust heat dissipation is distant fourth place consideration because it's complicated by way more than the metal of the pipes. As a principal, generally, one would NOT want heat dissipated from the exhaust to the chassis of a car. Finally, TI also has a markedly different sound.

Meanwhile, Steel's heat dissipation properties can vary as widely as can Titanium alloys, depending on some very precise properties of the alloys.

The phone heating issue has earmarks of software bugs that allow runaway factoring, hashing (or some other calculation process) owing to changes in the cpu's instruction set, particularly the instructions to monitor, throttle or snuff out runaway threads. What's less clear is why certain programs run afoul -- are they the programs that are poorly coded, or the ones that were correctly coded, or the ones that use dirty tricks, albeit correctly coded?
