Huawei proved to be using cheat mode in which performance is exploited only when the smartphone is benchmarked

When Huawei , the second largest share of the smartphone's worldwide market , detected a benchmark application, it turned out that it was exploding the score by launching a "back mode" different from the general mode.

Benchmark smartphone drama: We would not call it cheating, says Huawei, but look, everyone's at it • The Register

AnandTech pointed out Huawei's benchmark and cheat act. AndandTech has been known for criticizing the act of pretending smartphones to be high performance more than the actual ability, such as seizing the benchmark · cheat at Samsung's Galaxy S4 so far.

AnandTech's Andrew Fuluane and Mr. Ian Cutres compared benchmark results compared to Huawei's "P20" which uses exactly the same SoC while conducting a benchmark test with Huawei's high-end smartphone "Honor Play" I noticed that it was unusually high. In addition, since AnandTech confirmed that the results were scattered, such as P20's poor scores compared to the old model Huawei Mate 10, the score was improved with subsequent updates, so the more detailed the benchmark of Honor Play It seems that it was to be verified.

As a result of the verification, when Honor Play detects that a specific benchmark application is being executed, a high performance mode (BM mode) which is not performed in normal use due to power consumption increase and high heat generation is activated and benchmark It turned out that it was proved that it was raising the result.

Examining the power consumption during benchmark execution in GFXBench T - Rex (off - screen), the frame rate changed from 66.54 fps to 127.36 fps with BM mode on / off, and the average power consumption was 4.39 W in the normal mode In contrast to BM mode it has been confirmed that the explosion has increased to 8.57 W.

The BM mode adopted in Honor Play has excessive heating of the CPU and GPU, so it generates a large amount of heat, which may cause overheating of the smartphone and further consume more battery, so it is not suitable for general mobile use is. In other words, it can be said that there is a high possibility that the user misunderstands the performance of the terminal in the back mode only to bring out a good benchmark result.

AnandTech believes that performance of a smartphone can not be measured only by the speed of processing speed but should be evaluated after considering other important factors such as battery life and it is no longer considered that it should be judged only by the benchmark result It is.

Mr. Wang Chengle, software director at Huawei's Consumer Business Division, who was asked to answer about the existence of BM mode said, "Other companies have gained high scores by doing the same thing, as Huawei kept silent We admit that cheating behavior is implied, and we are excusing that benchmark results are necessary for competition with other companies, as the result of benchmarking influences consumer purchasing behavior.

As Huawei says, "We are looking for benchmark criteria to accurately reflect the user experience in cooperation with benchmark application developers," there are problems with current benchmark applications that can easily compare the performance of smartphones That's right. Forever the fact that the benchmark · cheat act does not go away may be reversed that the terminal reviewer and users rely on a simple and simple benchmark score as a performance comparison material. The benchmark cheat case will give you the lesson that you should no longer be overconfident in the benchmark application scores that do not reflect much on smartphone usage experiences.
