As soon as the iPhone 15 Professional overheating complaints began piling up, I mentioned I hoped the iPhone 16 wouldn’t even be impacted by overheating points. I mentioned I anticipated the iPhone 15 Professional’s chip to energy the bottom iPhone 16 fashions subsequent 12 months. One of the best ways to forestall overheating points can be to enhance cooling, reasonably 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 diminished overheating cases 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 a part of the A18 Professional, which is able to energy the iPhone 16 Professional variants. A brand-new chip technology might convey extra effectivity positive factors to the iPhone and, hopefully, scale back overheating. However next-gen A-series chips will even be extra highly effective, and so they’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 unique Apple GPT options to the iPhone 16 Professional and 16 Professional 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 characteristic for me.

If leaker KosutamiSan is appropriate, Apple is engaged on a graphene thermal system for the iPhone 16 sequence to enhance cooling. Furthermore, the iPhone 16 Professional battery will reportedly characteristic a steel shell.

It’s unclear if graphene cooling might be out there to all 4 iPhone 16 fashions, or why solely the iPhone 16 Professionals would get batteries with steel shells. To not point out that we’re nonetheless early within the iPhone 16 rumors season. Apple can attempt 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 mistaken about Apple’s USB-C cables for the iPhone 15 sequence.

However let’s bear in mind how highly effective the A17 Professional chip is. It may 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 area contained in the handset for Apple to squeeze an lively cooling system.

As we noticed from teardowns, graphite movies cowl components of the iPhone to enhance warmth alternate. That’s not sufficient, nonetheless. Graphite shouldn’t be graphene.

Smartphones will throttle efficiency when overheating to allow them to calm down. However that’s not one thing I would like from my future iPhone 16.

Utilizing a graphene system may enhance cooling considerably, however that’s simply hypothesis. A steel case for the battery would assist transfer warmth towards the iPhone’s exterior. This might assist with warmth dissipation. However once more, now we have no method of understanding whether or not it will actually work. Including extra steel contained in the telephone would additionally improve the burden.

If Apple will go ahead with this cooling thought, we must 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 appears to be like like on the within, in accordance with PBKreviews’ teardown.
