Huawei caught cheating benchmark test for P20 smartphones

Earlier this week, AnandTech revealed that the Chinese phonemaker has benchmark detection software installed on the Huawei P20, Honor Play, and possibly other devices packing its homegrown Kirin 970 processor, which makes the chip perform better by raising its power limit.

In the discussion, Huawei explained that its smartphones use an artificial intelligent resource scheduling mechanism.

On the heels of an in-depth analysis at Anandtech, UL Benchmarks (formerly Futuremark) has delisted Huawei's P20, P20 Pro, Nova 3, and Honor Play devices from its public 3DMark Sling Shot Extreme benchmark database.

Nokia’s upcoming Penta-lens camera phone receives MIIT Certification
However, the feature was recently removed on the Nokia 6.1 Plus , according to a thread on the Nokia community forum . It also has an URL link, which takes us to ze.media, which we believe will broadcast the launch event.

A few days ago we published our article addressing Huawei and Honor's inaccurate benchmarking behaviour.

As a response to the investigation, Wang Chenglu, President of Software at Huawei's Consumer Business Group, told AnandTech that the company wanted to follow the benchmarking standards that could meet the real-world experience and Huawei was doing so because "others do the same testing". It's not clear whether Huawei will continue to force the Performance Mode in smartphones during benchmark tests. Then, Huawei/Honor and UL Benchmarks discussed about this issue, and came out with an official joint statement.

Apparently UL and Huawei had a talk.

Rafael Nadal Progresses To US Open Quarter Finals
Isner defeated No. 25 Milos Raonic of Canada 3-6, 6-3, 6-4, 3-6, 6-2 and now faces the victor of the night match between 2009 U.S. Nadal holds a 7 to 3 advantage, though Thiem did beat Nadal earlier this year at the ATP World Tour Masters 1000 in Madrid .

Following reports of benchmark cheating, a number of Huawei smartphone models have been blacklisted by a certain testing company from their benchmark test - another blow to the smartphone company's approach to getting larger market shares. Manufacturers can still implement this kind of special performance mode on their devices, but UL says those modes must be off by default and can only be enabled by device owners.

The peaks are seen during the known benchmark apps' test and the subsequent troughs for the unknown, unlabeled benchmark apps, were blamed on Al by Huawei, saying that Al was the one that decided for those peaks. That's presumably part of the reason why Huawei is launching "Performance Mode" with EMUI 9.0. Huawei smartphones use advanced technologies such as AI to optimize the performance of hardware, including the CPU, GPU and NPU.

In normal benchmarking scenarios, once Huawei's software recognizes a benchmarking application, it intelligently adapts to "Performance Mode" and delivers optimum performance. Huawei according to UL, "is planning to provide users with access to "Performance Mode" so they can use the maximum power of their device when they need to".
