Huawei has been caught optimizing some of its top smartphones to over-perform on benchmark tests. On Tuesday, AnandTech discovered that Huawei’s P20 had been programmed to maximize performance specifically when running 3DMark, a popular benchmarking app. Today, the company behind 3DMark followed up with a statement saying that it had confirmed the findings and would delist the P20, as well as three other Huawei phones with similar behavior, from its benchmark leaderboards.

The delisted phones include the P20, P20 Pro, Nova 3, and Honor Play. Huawei admitted to this behavior in a statement given to Android Authority, saying that its phones are designed to adjust their performance based on the app that’s running.
