As soon as the iPhone 15 Pro overheating complaints began piling up, I mentioned I hoped the iPhone 16 wouldn’t also be impacted by overheating issues. I mentioned I anticipated the iPhone 15 Professional’s chip to energy the bottom iPhone 16 fashions subsequent 12 months. The easiest way to forestall overheating points can be to enhance cooling, relatively than depend on software program.
After that, Apple did certainly launch an iOS 17 replace to repair bugs within the working system. iPhone 15 Professional and 15 Professional Max customers reported that the repair lowered overheating situations with out impacting efficiency. However different individuals mentioned that their telephones had been nonetheless stricken by overheating points. As I mentioned greater than as soon as, some overheating is regular for smartphones, particularly when gaming or operating apps that tax the processor.
Different rumors then mentioned Apple may create a model new chip for the iPhone 16 and 16 Plus. A mysterious entry-level A18 processor might be part of the A18 Professional, which is able to energy the iPhone 16 Professional variants. A brand-new chip era might convey extra effectivity positive aspects to the iPhone and, hopefully, scale back overheating. However next-gen A-series chips can even be extra highly effective, they usually’ll clearly nonetheless generate warmth when operating extra intensive duties.
Now, two months after the iPhone 15 launch, an insider claims Apple is engaged on a graphene cooling system for the iPhone 16 sequence. And it’s a rumor I hope comes true.
I nonetheless haven’t upgraded my iPhone 14 Professional, and I don’t intend to this 12 months. It’s not as a result of the iPhone 15 Professional has overheating issues. Final 12 months’s mannequin continues to be nice for my wants. However I’ll get an iPhone 16 subsequent 12 months, particularly if Apple plans so as to add exclusive Apple GPT features to the iPhone 16 Pro and 16 Pro Max. Native generative AI help is my primary request for the upcoming iPhone sequence.
Then, I’d need higher battery life from my subsequent iPhone. Contemplating the iPhone 15 Professional’s overheating points, higher cooling would even be a top-three function for me.
If leaker KosutamiSan is right, Apple is engaged on a graphene thermal system for the iPhone 16 sequence to enhance cooling. Furthermore, the iPhone 16 Professional battery will reportedly function a metallic shell.
It’s unclear if graphene cooling will likely be obtainable to all 4 iPhone 16 fashions, or why solely the iPhone 16 Professionals would get batteries with metallic shells. To not point out that we’re nonetheless early within the iPhone 16 rumors season. Apple can strive varied concepts earlier than committing to something.
Additionally, whereas KosutamiSan has been correct earlier than, not all his predictions got here true. Most lately, he was fallacious about Apple’s USB-C cables for the iPhone 15 series.
However let’s bear in mind how highly effective the A17 Professional chip is. It might probably play console-grade video games, and it outscores Macs with M1 and M2 chips in benchmark exams. The rationale it overheats additionally has to do with cooling. There’s restricted house contained in the handset for Apple to squeeze an energetic cooling system.
As we noticed from teardowns, graphite movies cowl components of the iPhone to enhance warmth change. That’s not sufficient, nevertheless. Graphite will not be graphene.
Smartphones will throttle efficiency when overheating to allow them to calm down. However that’s not one thing I need from my future iPhone 16.
Utilizing a graphene system may enhance cooling considerably, however that’s simply hypothesis. A metallic case for the battery would assist transfer warmth towards the iPhone’s exterior. This might assist with warmth dissipation. However once more, we’ve no method of figuring out whether or not it might actually work. Including extra metallic contained in the telephone would additionally improve the load.
If Apple will go ahead with this cooling thought, we should always hear extra about it as we get nearer to the iPhone 16’s launch. Even when the rumor doesn’t pan out, I definitely hope the iPhone 16 may have higher cooling than the iPhone 15.
In the meantime, right here’s what the iPhone 15 Professional seems to be like on the within, in line with PBKreviews’ teardown.
