> Ming-Chi Kuo, an Apple analyst at TF International Securities, said any overheating issue was probably due to “compromises” in the phone’s design as the company attempted to reduce the product’s weight. > The iPhone Pro model has a frame made from titanium, a poor conductor of heat, which could hamper the handset’s ability to disperse heat. Previously, Apple has used stainless steel for its high-end phones.

  Well, it's not Thermal Conductivity then. I just looked it up. Stainless Steel 15 W/m-K Titanium 17 W/m-K Aluminum 210 W/m-K Effectively, Stainless Steel & Titanium have the same thermal conductivity. https://www.hardrok.com.au/thermal-activity-in-stainless-steel-compared-to-other-metals#:~:text=Stainless%20steel%20has%20among%20the,alongside%20its%20anti%2Dcorrosive%20properties https://www.hardrok.com.au/thermal-activity-in-stainless-ste....

    The issue here is users complaining that the phones get too hot to handle, which immediately eliminated conductivity. A thermal conductivity problem would've looked like the phone overheating without the outside getting too hot to handle. (picture the circuit board inside a thermos)

      that's not necessarily true. Heat has to go somewhere eventually. It could be that the CPU is much hotter than the temperatures felt on the frame. but yea, if the cpu is 45 C and the frame is 40 C, you'd be right.
