Snapdragon 888 mobile phone cooling comments: I didn't expect that the mobile phone with the worst performance is not easy to grab.

With regard to Snapdragon 888, the word-of-mouth of the market presents a two-level trend. Some mobile phones have good performance and high user evaluation; Some mobile phones are very unstable, especially in terms of heat dissipation, and have encountered the phenomenon that the temperature value is ridiculously high. The content of this test is the heat dissipation of some Snapdragon 888 models.

The test models are iQOO 7, OPPO Find X3 Pro, realme True Me GT, Redmi K40 Pro, Meizu 18 Pro and Tencent Red Magic 6 Pro.

Let's talk about the cooling measures of six mobile phones:

Tencent Red Magic 6 Pro has the most abundant heat dissipation means, and it is a three-dimensional and multi-dimensional heat dissipation system consisting of ultra-light nano centrifugal fan, heat dissipation canyon air duct, superconducting copper foil, thermal conductive gel, graphene and VC heat sink.

IQOO 7, OPPO Find X3 Pro, realme True Me GT, Meizu 18 Pro adopt liquid cooling for heat dissipation.

As far as the product details page is concerned, Meizu 18 Pro's liquid cooling scheme is the most common, that is, the common VC liquid cooling scheme. Perhaps the official feels that there is nothing to say, and can only use the statement of "super large VC liquid cooling area".

The liquid cooling heat dissipation of realme True GT is improved from the heat dissipation material, and the combination of "stainless steel+copper" is selected. Theoretically, the thermal resistance is lower, which can improve the heat dissipation efficiency to some extent.

The liquid-cooled steam chamber of IQOO 7 is designed with capillary structure, which adds a lot of heat dissipation channels, supplemented by heat pump, which can accelerate the flow of liquid in the steam chamber, which is different from ordinary liquid-cooled heat dissipation.

On the product details page of OPPO Find X3 Pro, there is no description about heat dissipation, but through the poster released by OPPO, it can be seen that the machine also uses VC liquid cooling for heat dissipation, and the core rhetoric is "super-large and ultra-thin", which is very similar to the description on the product details page of Meizu 18 Pro.

There is no description about heat dissipation on the product details page of Redmi K40 Pro, and we have not found other official publicity channels. Friends who have seen the K40 series conference in Redmi should know that Redmi has pinned its hope of heat dissipation on the peripheral device released at the same time-the frozen esports heat dissipation back clip. This is obviously not in line with the original intention of our test. The purpose of our test is the heat dissipation of the equipment itself.

Whether heat dissipation is good or not can't just depend on technology. Consumers are most concerned about the real heat dissipation effect, so we then conducted a heat dissipation test in three links: running, video recording and games.

There are two points for attention before the test:

The thermal temperature measuring gun used in our test will test many values, but the final value is the highest. ※.

※ Before each test, the mobile phone is fully charged.

Here are several rounds of tests.

Operating point

Select Ann Bunny as the running software. I chose this software because it takes about 10 minutes for each test, and it is a software with a long test cycle, which can release the performance of the mobile phone as much as possible. Each mobile phone is scheduled to be tested five times in a row (without rest), and the temperature is measured after each operation. The following are the concrete results.

iQOO 7

The maximum initial temperature of the front is 29.7, and the back is 29. 1.

Although our plan is to test each mobile phone five times in a row, iQOO 7 only completely tested 1 time, and the second and third tests were forced to quit before they were finished, so our second and third temperature measurements were taken immediately after the mobile phone was forced to quit.

After the third game, the highest temperature on the front was 50.7, and the highest temperature on the back was 47.4. This is a rather exaggerated temperature value. It is estimated that the reason for the forced retreat is that the system is for security reasons, so we did not carry out the following tests. If the test continues, the phone will probably be forced to leave the machine because of overheating.

OPPO Find X3 Pro

The maximum initial temperature of the front is 29.5 and that of the back is 29.7.

For some reason, the test interface of the second game always shows 28% progress bar, so the test of this game is not completed. Because of special circumstances, our temperature measurement time this time is 10 minutes after the mobile phone is turned on and running. Under normal circumstances, the time for Ann Bunny to run a game is almost 10 minute.

During running, the highest temperature on the front appeared after the third run, 38.8, and the highest temperature on the back was 35.7, which also appeared after the third run.

The last two temperature measurements are not high. Personally, I guess the mobile phone doesn't run at full power, because after Ann Bunny's revision, the chips of Snapdragon 888 usually run above 800,000, but the last two runs of OPPO Find X3 Pro are only about 700,000, which is obviously not the real strength of Snapdragon 888.

Realme zhenwo GT

The maximum initial temperature of the front is 30.4, and the back is 29.4.

During running, the highest temperature on the front appeared after the third run, with a temperature value of 4 1.7 and the highest temperature on the back was 37.9, which also appeared after the third run.

The running state of realme Real GT is very similar to that of OPPO Find X3 Pro. The last two temperature measurements were not high, and it should also belong to running without full firepower. In the first three tests, the running score was almost 850 thousand, in the fourth test, it was only 770 thousand, and in the fifth test, it was even lower, only 750 thousand It is worthy of being the three brothers of the "green factory", and many situations are so similar.

Redmi K40 Pro

The maximum initial temperature of the front is 29.7 and that of the back is 29.5.

During running, the highest temperature on the front appeared after the fifth running, with the temperature of 50.0 and the highest temperature on the back of 49.7, which appeared after the fourth running.

In the fourth test, I received a system prompt that the temperature was too high. After we choose OK, the mobile phone will continue to run. The last two tests of mobile phones should also belong to full fire running, because the running scores of the last two tests are not particularly different from those of the first three tests.

Meizu 18 Pro

The maximum initial temperature of the front is 29.4 and that of the back is 28.9.

During running, the highest temperature on the front appeared after the fourth run, with a temperature value of 4 1.8 and the highest temperature on the back was 39.8, which appeared after the second run.

After five tests, the temperature values of the last four tests are very close, and the highest temperatures on the front and back are around 40. It seems that this temperature is the limit of mobile phone operation.

Tencent Red Devils Game Phone 6 Pro

The maximum initial temperature of the front is 29.3, and that of the back is 29. 1.

Tencent Red Magic 6 Pro has a special "rapid cooling" option, so we didn't turn on this cooling mode during operation. After the fan is turned on, it buzzes, and the air holes on the left and right sides of the middle frame can also obviously feel the wind from the air-cooled fan.

In the process of charging, we didn't turn on the "fast cooling" mode, and only turned it on during the test, so the subsequent test even appeared below the initial temperature.

During running, the highest temperature on the front appeared after the fifth run, 32.5, and the highest temperature on the back was 30.7, which also appeared after the fifth run. Running points should belong to running points with full firepower. The scores of the five running scores are very similar, and the running scores are all around 840,000.

summary

By comparing the temperature curves, it can be found that the overall temperature values of iQOO 7 and Redmi K40 Pro are on the high side, and the highest temperature can reach about 50. OPPO Find X3 Pro, realme True Me GT and Meizu 18 Pro are in the middle echelon. Tencent Red Magic 6 Pro has fans "plug-in" blessing, and the overall temperature value is low.

The average front temperature (excluding the initial temperature) ranks the highest, reaching 47.76, followed by iQOO 7, with an average temperature of 46.93. 3~6 people are Meizu 18 Pro(40.48), realme True Me GT(36.40), OPPO Find X3 Pro(34.68) and Tencent Red.

The average temperature on the back (excluding the initial temperature) ranks the same as that on the front, and 1 ~ 6 are Redmi K40 Pro(46.98), iQOO 7(43.97), Meizu 18 Pro(37.06), realme True Me GT(34.04) and OPPO Find X3pro (32.

This version is Ann Bunny, which is a big revision after the update. Different mobile phones have completely different "attitudes" towards running. Some mobile phones will run with full firepower (iQOO 7, Redmi K40 Pro), and some mobile phones will run leisurely after the temperature is too high (OPPO Find X3 Pro, realme True Me GT), so the deviation temperature value can only be used as a reference. Because the performance of some mobile phones has not been fully released, it cannot represent the absolute heat dissipation ability.

videotape

The purpose of choosing video for testing is very simple, and long-term video recording consumes the computing power of mobile phone ISP. Friends who have made videos or played time-lapse photography know that the video machine will heat up after being used for a long time, so it is very targeted to test the heat dissipation with video. When testing, the mobile phone selects the option of 1080p 60 frame, and the screen of the mobile phone is adjusted to the brightest. We measure the temperature every 10 minute and record it continuously 1 hour. Here are the specific test results.

iQOO 7

The maximum initial temperature of the front is 26.5, and the back is 26. 1.

In the process of video recording, the highest temperature on the front appeared in the test after 60 minutes of video recording, the temperature value was 42.0, and the highest temperature on the back was 39.0, which also appeared in the test after 60 minutes of video recording. After 20 minutes of video recording, the temperature value tends to be stable.

OPPO Find X3 Pro

The maximum initial temperature of the front is 28.9 and that of the back is 28.5.

In the process of video recording, the highest temperature on the front appeared in the test after 40 minutes of video recording, the temperature value was 44.4, and the highest temperature on the back was 4 1.4, which also appeared in the test after 40 minutes of video recording. After 30 minutes of video recording, the temperature value tends to be stable.

Realme zhenwo GT

The maximum initial temperature of the front is 26.8, and the back is 26.0.

In the process of video recording, the highest temperature on the front appeared in the test after 50 minutes of video recording, the temperature value was 38.6, and the highest temperature on the back was 35.3, which also appeared in the test after 50 minutes of video recording. With the advance of video recording time, the overall temperature of the machine showed an upward trend, and only after 60 minutes of video recording, it decreased in a small range.

Redmi K40 Pro

The maximum initial temperature of the front is 27. 1, and that of the back is 26.3.

In the process of video recording, the highest temperature on the front appeared in the test after 60 minutes of video recording, the temperature value was 44.6, and the highest temperature on the back was 42.3, which appeared in the test after 50 minutes of video recording.

Meizu 18 Pro

The maximum initial temperature of the front is 25.8, and the back is 24.8.

In the process of video recording, the highest temperature on the front appeared in the test after 60 minutes of video recording, the temperature value was 4 1.2, and the highest temperature on the back was 39.8, which also appeared in the test after 60 minutes of video recording. After 20 minutes of video recording, the temperature value tends to be stable.

Tencent Red Devils Game Phone 6 Pro

The maximum initial temperature of the front is 30.6 and the back is 28.0.

Before the video recording, we started the "rapid cooling" mode.

In the process of video recording, the highest temperature on the front appeared in the test after 50 minutes of video recording, with the temperature value of 30.9 and the highest temperature on the back of 29.2, which appeared in the test after 60 minutes of video recording. Due to the existence of the fan "plug-in", the temperature is fluctuating, but the temperature value is very low.

summary

By comparing the temperature curves, it can be found that the overall curve positions of OPPO Find X3 Pro and Redmi K40 Pro are relatively high. IQOO 7 and Meizu 18 Pro followed closely. Tencent Red Magic 6 Pro has a low overall temperature due to the "plug-in" blessing of fans.

The average frontal temperature (excluding initial temperature) ranks 1~6, which are Redmi K40 Pro(42.80), OPPO Find X3 Pro(42.08), iQOO 7(4 1. 17) and Meizu18pro (42.08).

The average back surface temperature (excluding initial temperature) is ranked as 1~6, which are Redmi K40 Pro(40.55), OPPO Find X3 Pro(39.27), Meizu 18 Pro(38.77), iQOO 7(37.95) and Realme True Me GT (32.655).

In the daily use of mobile phones, games are the easiest thing to get hot, so this round of tests has great reference value in real life. The game is Peace Elite. Choose 5G network when testing. When testing, the screen brightness is the highest. The quality of the building is "ultra-high definition" 4K modeling, and the number of frames is "ultra-high". We measured the temperature every 10 minute and played for 2 hours continuously. The following are the specific test results.

iQOO 7

The maximum initial temperature of the front is 25.8, and the back is 24.8.

During the game, the highest temperature on the front appeared in the test after 80 minutes of the game, with the temperature value of 43.2 and the highest temperature on the back of 40.7, which appeared in the test after 30 minutes of the game. The game lasted about 50 minutes, and the game appeared frame locking, and the picture quality and overall fluency were not as good as before. This situation lasted for about 20 minutes. So after 60 minutes and 70 minutes, the back temperature dropped significantly.

OPPO Find X3 Pro

The maximum initial temperature of the front is 25.6, and the back is 24.7.

During the game, the highest temperature on the front appeared in the test after 90 minutes, the temperature value was 43.6, and the highest temperature on the back was 40.4, which appeared in the test after 40 minutes.

As far as personal game experience is concerned, the early stage is ok, but after about 40 minutes, the game experience is very poor. I feel that this phone will often lock frames. After the temperature of the mobile phone rises to a certain value, the temperature value will gradually decrease, but at the same time, the fluency of the mobile phone will also decrease obviously. After the temperature stabilizes, the fluency will gradually recover. (PS: We will use Snapdragon 888' s mobile phone frame rate for long games later. Welcome to continue to pay attention. )

Realme zhenwo GT

The maximum initial temperature of the front is 27.4, and the back is 27.5.

In the competition, the highest temperature on the front appeared in the test 30 minutes after the competition, the temperature value was 43. 1, and the highest temperature on the back was 39.7, which appeared in the test 90 minutes after the competition. As far as the somatosensory state is concerned, it is very similar to OPPO Find X3 Pro, and it feels like there is a frame lock in the middle.

Redmi K40 Pro

The maximum initial temperature of the front is 25.4, and the back is 24.8.

During the game, the highest temperature on the front appeared in the test after 120 minutes, the temperature value was 44. 1, and the highest temperature on the back was 43.0, which appeared in the test after 30 minutes.

This phone doesn't feel obvious screen lock (at least) when playing, but the overall game temperature is high, and the middle finger, ring finger and thumb supporting the back shell of the phone feel very hot.

Meizu 18 Pro

The maximum initial temperature of the front is 28.8, and that of the back is 28.8.

The highest temperature in the front of the game appeared in the test 70 minutes after the game, with the temperature value of 43.6 and the highest temperature in the back of the game of 46.4, which also appeared in the test 70 minutes after the game.

To be honest, this hand tour feels very unsmooth after 30 minutes. The temperature of the front screen is not particularly high, which is acceptable to fingers most of the time, but the temperature on the back is really high, which makes the middle finger and ring finger of the mobile phone feel uncomfortable.

Tencent Red Devils Game Phone 6 Pro

The maximum initial temperature of the front is 26.5, and the back is 25.7.

During the game, the highest temperature on the front appeared in the test after 70 minutes of the game, the temperature value was 4 1.0, and the highest temperature on the back was 39.3, which also appeared in the test after 70 minutes of the game.

The whole game process is very smooth and the temperature value is not particularly high. Compared with other mobile phones, it is totally cool. Even after the "rapid cooling" is turned on, the noise made by the fan is a bit noisy, and sometimes it even interferes with the judgment of the position of the gunshot. Personally, I think this phone is really suitable for playing games. After all, the title is a game phone, but it is not recommended to keep the "rapid cooling" mode on.

summary

Observing the temperature curve, the whole body is in a staggered state. The front Redmi K40 Pro curve is at the top, and the back temperature curve Meizu 18 Pro is at the top.

The average frontal temperature (excluding the initial temperature) ranks 1 ~ 6, which are Redmi K40 Pro(4 1.86), Iqoo 7(4 1.43), Meizu 18 Pro(40.24) and oppo find x3 pro (40.24).

The average back surface temperature (excluding initial temperature) ranks 1 ~ 6, which are Meizu 18 Pro(4 1.46), Redmi K40 Pro(40.88), iQOO 7(39. 13) and RealMe GT (39.

abstract

From the user's point of view, Tencent Red Magic 6 Pro is the first gear in terms of temperature comfort.

About four hours of testing time, the long-term temperature is only about 30. It is not surprising that its comfort ranks first. After all, it is a game mobile phone, which has established a very systematic three-dimensional multi-dimensional heat dissipation system, especially for fans like "plug-in". When the temperature is high, you can blow the wind to cool down, and you can also feel the cool wind blowing from the cooling hole when playing games.

Realme True Me GT and OPPO Find X3 Pro are second gear.

Their temperature will be higher than that of Tencent Red Magic 6 Pro, but most of the time they are within the range that the skin can bear. Take the game as an example, the back supported by fingers generally does not exceed 40, and their liquid cooling does have a certain effect.

Meizu 18 Pro and iQOO 7 are the third gear.

Meizu 18 Pro in the actual game link, the back temperature is surprisingly high, once soaring to 46. For example, playing games with Meizu 18 Pro is equivalent to dragging a warm baby in summer.

As for iQOO 7, although the running temperature of Ann Bunny after the revision can only be used as a reference (PS: users don't often run points during normal use), the actual game link temperature is also relatively high, and both the front temperature and the back temperature rank higher. On the product details page of iQOO 7, the description of capillary structure and power pump is a kind of hype, and the actual effect is not particularly obvious.

Redmi K40 Pro belongs to the fourth gear.

In the ranking of six average temperature values, the machine "won" five firsts and one second. The maximum value generated in the test is generally generated by this mobile phone. In the actual game session, the temperature on the back of the fuselage is generally above 40. After two hours of games, the middle finger, ring finger and thumb supporting the back shell of the mobile phone are a little wet, indicating that the testers who don't sweat have left a lot of sweat stains. This mobile phone used to be difficult to grab, and many friends who are eager to buy choose to increase the price to find scalpers.
