Apple has acknowledged user complaints that iPhone 15 and 15 Pro phones are overheating, reports Forbes, but said that contrary to speculation, it has nothing to do with the phone’s hardware design. Forbes noted an update to Instagram has already rolled out with version 302, released September 27th, to address some of the issues.
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. Also the iPhone 15 pro models are only titanium on the sides (all the way around the phone). The chassis is still Aluminum and the back is still glass.
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!
