In almost every press conference of the Android camp today, heat dissipation has become the focus of the talk, such as "stacked waterfall VC stereoscopic cooling system", "all-weather atomic-level heat dissipation engine", "diamond ice core cooling system" and other scare words emerge in an endless stream, and some game phones even plug the cooling fan into it. But compared to the luxury heat dissipation configuration of Android, the heat dissipation of the iPhone is much more shabby, it can be said that it is almost nothing, and even at the Apple conference, it has never been mentioned, why is this so? Let's talk about it.

First of all, the internal structure of Apple's mobile phone is very compact, combined with its simple internal design principles, so that the internal existence of the iPhone is "necessary" components (Apple believes necessary), and the placement structure is simple and orderly.

Why is it said that there are only necessary components inside the iPhone? Isn't heat dissipation necessary for a mobile phone? The answer is obvious, heat dissipation is very necessary for both computers and mobile phones, but the iPhone is not installed with a heat sink like an Android phone, in addition to the internal body design there is no extra place to place the heat dissipation board, the main thing is that Apple chose to solve the problem from another angle, that is, to improve the energy consumption ratio of the chip.

As we all know, Apple's A-series chips, whether it is CPU or GPU, have always been leading the same generation. Taking the recent high popular Qualcomm Snapdragon 8 Gen 1 as an example, according to the CPU test data of Geekbench 5, the A15 single-core is 1724 points, multi-core 4587 points, while the Snapdragon 8 Gen 1's single core is 1204 points, and the multi-core is 3654 points, which are 30% and 20% behind, respectively.

According to Geek Bay data, in terms of CPU multi-core, the energy consumption ratio of A15 is 570 points /W, while the Snapdragon 8Gen1 is only 343 points /W, lagging behind by nearly 40%; and the same is true of the GPU energy consumption ratio, the Snapdragon 8Gen1 is 3.84 points /W, while the A15 is 6.84 points /W, almost only half of the level.
Specifically, in terms of GPU, the data of snapdragon 8 Gen1 is only barely keeping up with the A15 residual version. Geek Bay's test results show that in the 1440P high-voltage test, the A15 full-blood version has a running score of 54 points, while the Snapdragon 8Gen1 is 43 points, lagging behind nearly 20%.
In terms of peak performance, in the same test state, the Snapdragon 8 Gen 1 and A15 Residual Editions have the same score, but the power consumption of the A15 is only 6.5W, while the power consumption of the Snapdragon 8 Gen 1 is 11.2W.
In addition, when the mobile phone is in a medium and high frequency load, for example, in the case of the Bright Mountain Lock 1080P 30 frame, the Snapdragon 8 Gen1 came to a 4.1W score, compared with the Snapdragon's previous processor, this score has indeed improved a lot, but compared with the residual blood version of the Apple A15, the distance is still relatively obvious, not to mention the A15 full blood version of only 3W.
To put it simply, when the mobile phone encounters thermal problems, the Android mobile phone chooses to install a cooling system or even a cooling fan to solve the problem, while the Apple mobile phone chooses to alleviate the performance ratio of the chip, that is, the processor performance ratio of the mobile phone, which is the difference between the two major systems.
There is such a small story about Apple's internal design, in 1980, Apple launched a computer called "apple III.", in the design of the sample, in order to make the computer run more quietly and elegantly, Jobs canceled the computer's cooling fan without authorization, although the engineer repeatedly stressed that no fan computer will crash due to component heating, but Jobs's answer is always a sentence "you don't understand." Now the development of Apple's A-series chips seems to prove that Jobs's decision was correct.
Apple's pursuit is a humanized product aesthetic, and it has a paranoia about beauty from the inside out. In addition to the simple beauty, there is also the tactile beauty and detail beauty of the user experience. In order to give users the most subtle experience through a technology product, Apple is committed to creating the ultimate sense of operation from the tactile aspect, which is a more intuitive and direct finger operation of the interface.
At the same time, the same excellent detail beauty requires many components to support the completion. From the appearance design of Apple's mobile phone, such as the waterproof function of the mobile phone, dual speakers, and the induction of light, etc., it is necessary to support the components in order to achieve the fine and humanized nature of the current Apple mobile phone. It can be said that Apple's mobile phone has an exclusive theory of technological design, but in this case, heat dissipation may not be the focus of Apple's thinking.
In summary, Apple is not unaware of the heat dissipation problem of brand mobile phone products, but deliberately points to different technology trees, by vigorously improving the energy consumption ratio of the processor to achieve the root of the heat problem, but at present Apple has not yet achieved its ideal effect.
