This last round of testing is nothing more than a comprehensive test, and after several rounds of testing, no problems were found, but testing this kind of thing does not mean that there is no problem the first time, there is no problem the second time, and there will be no problem in the third time.

Otherwise, how could those car manufacturers recall the vehicles they sold from time to time, because they didn't test them before they were put on the market?

Not necessarily, before leaving the factory, it must have been tested and inspected many times, and no problems were found in the results, but after it was sold, consumers found problems.

Therefore, although it seems to be a sure thing, it may not be that there will be no problems in this test, and there may be problems.

"CPU Temperature is Normal"

"The system is working properly"

"The screen is displayed normally"

How can there be no professional test equipment for the test, among them, for this test, a number of monitoring software has also been developed, so that the mobile phone is connected to various interfaces, and then linked to the monitoring software in the computer, which can be used to monitor the operation of the major hardware and software inside the mobile phone.

"Open the app randomly!" Lin Yashi was the person in charge of this test, she stayed next to Tang Hao, and remotely commanded the test work.

In the past, she went out in person, and this time she wanted to go out in person, but when the big boss came to the scene, she couldn't leave the big boss alone, and in the end she could only let the people below do it, and she was responsible for commanding.

"Open the Penguin app. View CPU usage"

One of the staff members in charge of controlling the phone opened the penguin's chat app. Report the number of the next step jù monitoring.

"Normal!"

"Switch to running in the background. CPU occupancy"

"CPU usage is decreasing!"

Foreground running and background running are two modes, just like the maximization and minimization of the computer, when you maximize, the proportion of running will increase, and minimization, which is the background running mode, will definitely decline, which is common sense.

"Try running in the background. Open the other apps again. Lin Yashi ordered.

This time the test is definitely not only a test of the phone's hardware, but also a test of the operating system.

Whether it is a KT mobile phone or a COS operating system, they all belong to the same company, if one of them has a problem and one of them has no problem, it is not the result that Tang Hao wants.

The result he wants is that the two are combined, and this integration has a professional name, which is called compatibility!

Compatibility is important, if the compatibility is not good. The result can be imagined, wasting the running space resources of the mobile phone. It also can't play the powerful performance of the operating system.

Whatever the point, compatibility is very simple.

Of course, it is impossible to achieve 100% compatibility, and 100% compatibility only exists in theory, not in practice.

Unless someone really develops a completely intelligent operating system one day, which can make the operating system evolve and mutate automatically, it is possible to achieve 100% compatibility.

Many people say that the compatibility is very good when it comes to compatibility in software and hardware, and few people dare to say that it is 100% compatible.

100% compatible, that is the limit of the two, that is to say, the biggest limit of your hardware, and the limit of the operating system, and this limit is obviously unattainable, either the hardware affects the play, or the operating system is not perfect enough, which affects the play.

In short, there is always a problem in between, which prevents it from reaching its limits.

Don't forget, a small problem with a piece of hardware, such as not being perfect when talking about tin, may affect the performance of the entire component, and those hardware are made by people, or people control the machine, how can it be 100% perfect.

"Normal!"

"The number of items is normal!"

"Open another app."

Lin Yashi once again gave the order: "Switch to background running, cut the screen." ”

"The occupancy rate has increased, the screen is not stuck at all, and there is still 65% of the memory space."

"What's the temperature of your phone?" Lin Yashi asked.

"15 degrees!"

"Open the mobile game and play for ten minutes." Lin Yashi still attaches great importance to the temperature of the mobile phone.

The temperature may seem small, but it's very important, because when the application is running at high speed, causing the CPU to run at high speed, it will generate heat, and then the temperature of the whole phone will rise.

The COS operating system has a hard standard, that is, the temperature cannot exceed 27 degrees, once this degree is exceeded, the operating system will force the shutdown program to start.

For example, if you run a huge mobile game application and play for a long time, the temperature of the mobile phone keeps rising, and within the time together, if you can't control the heat dissipation and let the temperature reach 27 degrees, then the phone will be turned off.

In this case, consumers will only list your product as one of the problematic products, so that not many people will buy your product.

"What is the maximum amount of the previous test when using mobile games?" Tang Hao asked curiously.

"There was no pause in between, and the temperature was 23.3 degrees for an hour."

Lin Yashi paused, and added: "Because it is a metal back shell, even if it is 23.3 degrees, I feel that the temperature is very high. ”

"An hour?"

Tang Hao pouted, he had already gotten the answer he wanted, an hour is a long time, and there are crazy people who play mobile games for an hour in a row, but after an hour, 23.3 degrees, it is already qualified, because he knows very well that once the mobile phone is placed on the ground, the metal back shell can quickly dissipate heat, even if you are still running the mobile game at this time, you can still dissipate heat.

In this way, even if you play the mobile game for more than half an hour, you will not be afraid of shutting down.

"Our battery is a problem, in the standby state, it can be used for 133 hours, but if you continue to talk and play some applications, the power consumption is very fast, under normal circumstances, it will not last more than 30 hours, and the continuous hour of mobile games, the power consumption is as high as 36%." Lin Yashi is obviously not satisfied with the battery.

"That's what smartphones are all about."

Tang Hao didn't think it couldn't be, there should be such a number jù, it should be very good, but the shortcomings, he will not put down, and said at the moment: "In the research of batteries, you can increase investment, with the emergence of larger mobile games, the higher the requirements for batteries." ”

"The battery is really a hard wound." Yang Lan also agreed
