you certainly didn’t expect that there would be a sequel to this year’s iphone 16 series review.

did you instantly feel like you were following a drama?

let me give you some background information first. after we completed a comprehensive review of the new iphone, we suddenly thought of something - guozi specifically emphasized the upgrade of heat dissipation at this year's press conference.

according to them, after upgrading the new heat dissipation structure,the sustained performance of iphone 16 and 16 pro when playing games is improved by 30% and 20% respectively.

this is a rare thing in the entire history of iphone.

guoguo, you make me feel strange!

so tony and i are very curious: what exactly is the heat dissipation upgrade apple is talking about this time? is there really such a big improvement?

in order to clarify this problem, we also found the iphone 15 and 15 pro for comparison, and even dismantled all four phones in one go.

let’s talk about the specific situation slowly next.

first of all, the first thing we explored is what the heat dissipation level of this generation of iphone 16 and 16 pro is compared to the previous generations of iphone 15 and 15 pro.

because guozi only mentioned 30% and 20% improvements at the press conference, and did not mention which generation model it was compared with.

really, we stared at the frame and looked at it several times with a magnifying glass, but we couldn't find the line of small print at the bottom that marked the comparison model.

guoguo is not confident anymore?

eh~ in this case, we have to find the answer ourselves. let’s go straight: genshin impact, qi. . .

can't start at all. . . because after measuring the xumi city running map for 30 minutes on each of the four machines, the frame rates were almost the same at 59 frames. this does not reflect the difference at all!

it can only be said that the optimization of genshin impact has indeed improved now, and pro models can run up to 120 frames, so this time we had to change the test project from genshin impact to its good brother: star iron ,start up!

after 30 minutes of running the xingchahai hub, the frame rate and temperature performance of the four models finally opened up a relatively obvious gap.

the average frame rate of the iphone 15 is only 44.9 frames, the temperature on the back is 50 ℃, the front is 47.4 ℃, and the power consumption is 4.3w (4280.7mw rounded).

in comparison, the average frame rate of the iphone 16 has reached 57.6 frames. based on this calculation, the frame rate has indeed increased by about 28%, which is very close to apple’s claim of a 30% increase. therefore, we have solved part of the previous puzzle. .

in terms of temperature and power consumption, the back of iphone 16 is only 48.3 ℃, the front is only 44.1 ℃, and the power consumption is an outrageous 5.3w (5289mw rounded)

why do you say it is outrageous? because if you read on, you will find that it actually has the highest power consumption among the four mobile phones we tested this time!

i even suspect that the one we have is the chosen one, and its physique is one of the better ones among the standard version.

of course, the matter of physical fitness is purely my personal guess. i will analyze the specific reasons why the 16 performs like this in the later disassembly process.

here we continue to talk about the performance of the two pro models.

the average frame rate of iphone 15 pro is 57.7 frames, the back temperature is 51.1 ℃, the front temperature is 49.1 ℃, and the power consumption is 5w (4919.8mw rounded), which is indeed in line with our consistent impression of a17 pro, it is hot!

but what i didn’t expect this time was that the iphone 16 pro was a bit small?

its average frame is only 0.1 frames more than that of the 15 pro, and its power consumption is only 4.6w. under the premise of upgrading to ios 18, i don’t know why the game scheduling of 16 pro is very weak.

this is obviously not up to what apple said before, that the sustained performance release of 16 pro is improved by 20%, okay!

um. . . isn’t the comparison model of 16 pro 15 pro? let’s put a question mark here and discuss it with you again when we have the opportunity.

from another perspective, we have to admit that this kind of cowardly scheduling is not completely without benefits.that is, the temperature on the back of the 16 pro is only 47.8 ℃, and the temperature on the front is only 42.9 ℃., which can be regarded as the one with the best temperature performance among the 4 models we measured.

moreover, by analyzing the frame rate curve, we can also see that its frame rate is obviously more stable than that of the 15 pro.

i don’t know if you have seen it before. in geek bay’s video interview with apple’s chip boss, johny srouji repeatedly emphasized to yunfei – “we at apple do not pursue extreme running scores, we pursue continuous performance release. ”

okay, okay, you old man really do what you say!

here i have listed the game frame rate, temperature, and power consumption of these machines so that you can have a more intuitive look ~

after talking about the actual game testing part, let’s go straight to the disassembly and see what guozi has done on the heat dissipation of the fuselage this time.

let’s first look at the two standard versions of the iphone. they both have a very typical sandwich structure, with the screen and back panel sandwiched between a layer of aluminum metal frame.

one of the obvious changes in 16 is that,the motherboard has been changed to an "l" shape, the chip has been changed from the right side to the center, and the structure around the chip has also been optimized for heat dissipation.。

the benefits of this are obvious,the heat will no longer be concentrated on the sides, but can be dissipated in the middle of the fuselage.

as for the "100% recycled aluminum heat sink structure" mentioned by guozi at the press conference, we found that it seems to be similar to the aluminum plate of the previous generation 15.

it’s just that the shape is a little different, and there’s an extra layer of graphene heat dissipation film on the side that’s in contact with the screen.

when we dismantled the machine to this stage, i was still complaining in my mind: why do you have to save money on the heat dissipation film? if this 15 also has such a heat dissipation film, will the heat dissipation be better and the performance be stronger? ?

but the result is a bit of a slap in the face, but please allow me to get it out of the way first. we will talk about this small cooling film later. here we will continue to talk about the disassembly of the two pro versions.

after taking apart the iphone 15 pro and 16 pro, we will find that the 16 pro is also a classic sandwich, while the structure of the 15 pro is a little different. the aluminum frame and back panel at the bottom form a bottom case, and the components are assembled here. inside the bottom case, the screen is finally encapsulated.

however, since the components of the 15 pro are closely adjacent to the screen, it is actually not conducive to heat dissipation. even if there is a large graphene heat dissipation film on the back of the screen, it is better than nothing.

in addition, compared to the 16 pro, another disadvantage of the 15 pro is that due to the presence of the wireless charging coil, a large hole needs to be opened in the middle of the aluminum plate. as a result, the heat conduction area of ​​the aluminum plate is also much smaller. less, further weakening the heat dissipation capacity of the entire machine.

therefore, the heat dissipation improvement of this year’s 16 pro is also due to structural changes, but it changes the internal frame of the entire fuselage.

the sandwich structure allows it to have a larger aluminum plate for heat dissipation, and the so-called solid-state diffusion technology, according to my understanding, is that apple better integrates this aluminum plate with the titanium middle frame, so that the heat can be it is transmitted more evenly to the entire fuselage.

at the same time, apple has increased the coverage area of ​​the graphene thermal film, allowing the heat generated by the screen and motherboard to be conducted to the aluminum plate with higher efficiency.

to prove this, we did another round of testing - after removing the graphene thermal film in the iphone 16 and 16 pro bodies, the iphone 16's star iron frame rate dropped from the previous 57.6 frames to 55.7 frames. power consumption has also dropped to 4.6w (4585.8mw).

the 16 pro dropped directly from 57.8 frames to 48.2 frames, 10 frames less, and the power consumption was also reduced to 3.7w (3727.4mw). the body temperature was also a few degrees lower (42.9 ℃ on the front → 41.45 ℃ on the back, 47.8 on the back) ℃→ 45.3 ℃).

it can be seen that all the heat is accumulated inside and cannot come out.

judging from the body design of this year's 16 and 16 pro, i feel that apple has learned the lessons of the 15 pro, summed up some experience, and created a model that apple is working hard to improve in terms of heat dissipation. good student image.

but i want to say, guoguo, let’s talk about it. is there a possibility? you don’t have to summarize the experience in cooling at all. we can just copy the homework of the top android students next door.

wow~ it’s true. before disassembling the phone, i thought that apple had finally adopted the idea of ​​using a vapor chamber on its android flagship this year. after disassembling the phone, i found that there was still graphene here. . . accepted.

damn, forget it, it’s just a complaint, let’s call back the previous issue of the heat dissipation film - if the iphone 15 has a heat dissipation film in the same position as the iphone 16, will the heat dissipation effect be improved?

um. . . the answer is a little, but not much.

after we transplanted the heat dissipation film of the iphone 16 to the iphone 15, the frame rate dropped to only 41.4 frames and the power consumption was only 4w (4077mw) when running the star rail 15 for 30 minutes!

however, after observing the temperature measurement chart, we found that the temperature of the screen area has dropped a bit, indicating that this film does play a small role.

since it is somewhat effective, then... what if we put the film of the 16 pro on the back of the 15?

so we did some dirty work again.

it turns out, what . . . the number of frames rose directly to 49.8 frames, and the power consumption also came to 4.9w (4884mw rounded).

judging from the temperature measurement chart, the heat dissipation area of ​​the core heat source is obviously larger than before. but it still ran less than 60 frames.

at this point, we have almost finished talking about the topic of heat dissipation of the iphone 16 series.

finally, let me summarize for you my opinion on this cooling upgrade. in one sentence:the improvement is obvious, but it still sucks。

after all, the thermal conductivity of the aluminum plate determines that it always has a limit.the final answer may be vc vapor chamber。

as for the reason why the iphone's heat dissipation upgrade looks a bit awkward, i also helped apple fans "adapt" it a little bit.

it’s the interview video from geek bay. lao miao ni mentioned something in it. the chip team also knew that stacking materials could further improve the performance of the a-series chips. however, due to the body design, they had to make compromises to ensure the performance of the chips. low energy consumption.

this actually goes back to that commonplace topic. in apple's product planning process, it isdesign first, everything else must give way to design. to a certain extent, the laws of the ancestors are immutable.

for apple engineers, they have to consider the body size, maintenance solutions, especially the requirements for environmentally friendly and carbon-neutral materials. the combination of various requirements makes it difficult to improve the heat dissipation structure of the iphone.

in our opinion, apple is using a very complicated way to solve a simple problem, but the results may not be as good as the simple method used by android.

i'm very curious: how will apple view this matter, and how will it tell this story?
