iPhone 16 Rumored to Feature New Thermal Design
- Thread starter MacRumors
- Start date
- Sort by reaction score
People have been routinely predicting a price raise since the 6. Time for a new hobby.
So they are admitting of the overheating issues so next year they can turn back the heat on the 15 so people upgrade
Thermal resistance in electronics packaging is often dominated - not by thermal resistance of the bulk material (e.g., copper), but by the thermal interfaces. I have low confidence in graphene as a mature and deployable technology. They would likely use graphene as an interface layer, and they will have to watch yield very carefully. They likely already do x-ray every cpu after the mainboad is assembled to inspect the die for voids. As far as I know, graphene can't be bonded or physically attached well, there could be ageing problems with the interface if it isn't studied closely. The risk is that 4 or 5 years down the road, air voids could develop between the CPU and heat spreader /chassis and cause overheating in aged devices.
There was someone on MacRumors who has the exact same MagSafe charger as me, but his iPhone 15 Pro Max was overheating.
Sounds to me like those complaints were people not making use of their 14-day return period and exchange it for a good model.
Which means Apple has backed off of the performance to make up for poor thermal design.
This does seem sketchy because better heat conductivity in the heat sinks will make the electronics cooler, by making the case hotter.
My guess is that with the price of copper, this is only a cost reduction effort. After all that is what Cook is known for.
The 12 was an entirely new design. We’ve had the same design since the 12, but the X through 11 were a different design. So if you thought the X was perfect, there would have been no need for the redesign of the 12.
Apple could easily create a new industrial design again.
After having lightning for years and upgrading to the 15 Pro Max, I can say I really like USB-c on the iPhone and I wish apple did it sooner. You will like it too when you upgrade. Another quality-of-life update is the 8 GB RAM. Multi-tasking is much better, with far less app refreshes (where you lose the context that was in app and it starts over from scratch). In fact, I don't get any forced app refreshes/reloads anymore.
So I guess everything after the iPhone 1 onward was defective? Should've just stopped making new iPhones then rather than indirectly admitting that all their iPhone designs are defective...
Ti has a lower thermal conductivity than SS. As much as a factor of 2 depending on the SS alloy. Not sure how well Apple assesses that when considering new materials.
Jony Ive clearly did not assess the material and handling impacts when they decided to use the SS band as the antenna on the iPhone 4. Clearly evident Apple knew they had a problem, which is why they released the bumper cases at the same time and the legendary quote from S.J. “You are holding it wrong”.

Do we know if this is simply because the update throttles performance, thereby reducing heat generation? Better thermal management is never a bad thing, especially if it allows Apple to turn up their chips.
Not necessarily true. The update could just as easily fixed a run-away thread/process that was causing the heat in the first place.
I didn’t say we’ve had the same exact design since the X. I said since the X the designs have been good.
If you really want to get technical, the 15 models are different also due to the slightly rounded edges vs the 14 models.
Trust me, I would love to see your mockup of a new “industrial design” you are envisioning. Please share.
As far I’m concerned, it’s a phone and works a such. The designs since the X have been extremely comfortable in hand.
I think the use of such interfaces is often overlooked by consumers too. In older hardware that runs “hot” it’s usually because the interfaces between the processors and heat sinks has degraded/dried out etc
Replacing it is often a sure way to have a system running like new. I’m addition to removing built up dust.
