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."

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.

It’s almost like Apple is always working on new processes and materials when manufacturing products.

The entire story about iPhone 15 Pro overheating due to the titanium material was proven to be incorrect, and it was probably just propaganda started by someone at TSMC whispering in Kuo’s ear to shift blame from the A17 Pro.

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.

Not really, it’s pretty normal for Apple, or any other company, to try and make their products better than the model before it. If Apple wants to make the thermal design better, why wouldn’t they?

Yes, but the timing is a little suspicious. It sounds like it’s going to be a major thermal change, not the standard year-to-year minor change.

"Graphene has high thermal conductivity, surpassing that of copper, which is currently used in iPhone heat-sinks."

The iPhone has already had graphite for thermal conductivity, not sure if this random twitter account knows the difference. And what copper heatsink in the iPhone? It just sinks the heat from the chip through the graphite into the aluminum internal frame.

Can it have an ENTIRELY NEW DESIGN.

The timing of what? The "leak?" Because it's not the timing of tech... They didn't start working on graphene cooling systems this month... or this year... or even this decade. Graphene has been the holy grail for 20 years, and Apple has been working on it for a very long time, I promise you. This leak is timed to grab eyeballs and stir suspicion, and it's apparently working.

Is Apple slowly going the way of Intel?

At first, the Ax chips were all about efficiency. It now seems that every year they get a lot more powerful, but also a little bit warmer, and all these little bits warmer are adding up to needing cooling, and in years to come the efficiency has been lost and they’re just really powerful, hot, power hungry chips.

With what Qualicom just released. Apple is got a run for its money.

There is no overheating problem. That is why Apple is addressing better thermals.


Better batteries just in time for the new EU rules on batteries.



Plus a larger form factor, maybe next year I upgrade from my 14 PM…
