The previous phones were made of aluminium and stainless steel, both of which aren't great at heat dissipation either. Titanium's heat dissipation is about 17W/mK (imperial: 9.829 BTU/(h*ft*℉)), aluminium was much better, but the Pro was made of stainless steel (15W/mK or in imperial terms 8.673 BTU/(h*ft*℉)) which is a worse heat conductor than titanium.
The base models are losing quite a lot of heat conductivity but it's also hitting the Pro models which got a conductivity improvement.
The iPhone 15 base models are still Aluminum.
Ah, I guess I bought into the marketing.
In that case none of the phones have any negative side effects because of the thermal conductivity of the build materials at all.
Maybe, but I liked that you found the thermal conductivity for the different materials. I hadn’t even considered that it probably wasn’t the titanium until I started thinking about how those numbers for stainless and titanium were pretty close!
