iPhone 16 Rumored to Feature New Thermal Design

Apple plans to introduce a new thermal system on the iPhone 16 to reduce overheating, according to the leaker known as "Kosutami."

iPhone 16 Mock Header Updated 1
In a recent post on X (formerly Twitter), Kosutami explained that Apple is working on a graphene thermal system for the ‌iPhone 16‌ lineup, while the iPhone 16 Pro models could add metal battery casings to reduce overheating. The move appears to come in response to widely encountered overheating issues experienced with the iPhone 15 Pro, which Apple addressed through a software update earlier this year.

Graphene has high thermal conductivity, surpassing that of copper, which is currently used in iPhone heat-sinks. Apple has been interested in graphene for thermal management for some time, filing patents related to its exploration of the material for heat dissipation in portable devices. Apple previously transitioned the Apple Watch's battery from black foil casings to ones made of metal with the Series 7, so an equivalent change on the ‌iPhone‌ seems plausible.

Seems sketchy.

iPhone 15 overheating reports seem to have died down after the recent software updates. My 15 Pro doesn’t get any warmer than my 13 mini did when being pushed.

I don't think it's going to be hit with consumers...

I wonder how they never caught the heat issue during the device’s testing phase.

If there wasn’t a defect in the design with the current generation (like Apple said), then they wouldn’t be changing it for the next generation.

Good ol’ indirect self admission.

Any excuse to hike the price, I guess.

My 15 Pro Max has never got warm nevermind hot.

What is 'black foil' if not also metal?
Wait, is this an X-Files thing (black oil)? ?
