Back in 2013, benchmarking firm 3DMark delisted the results from several devices. The Samsung Galaxy Note 3 (both Snapdragon and Exynos versions), Galaxy Note 10.1 (2014) tablet, HTC One (M7) and HTC One mini were removed from the 3DMark site for cheating. How did these devices game the system? Samsung and HTC allegedly included software on the aforementioned devices that had their processors run at maximum speeds when benchmark apps were run.
UPDATE: Huawei has issued a rather lengthy statement today.
Today, 3DMark has delisted several Huawei handsets (including one Honor model) after it reached the same conclusions as a published report. The latter called out Huawei for inflating the benchmark results on models like the Huawei P20 Pro, Huawei Nova 3 and the Honor Play. This has the effect of making these models appear to run faster than competing phones. Benchmark apps are designed to quantify the performance of certain aspects of a handset for comparison purposes. The 3DMark app in the Google Play Store measures an Android phone's CPU and GPU performance using different tests that are each designed specifically for low-end to high-end handsets.
Like it did with Samsung and HTC five years ago, 3DMark accused Huawei of including software on the P20 Pro, Nova 3 and Honor Play that recognized when a benchmark testing app was running, and pushed the processors on the phones to run all out. Usually, only phone enthusiasts even bother looking at benchmark scores. An even smaller number will consider the results when purchasing a new phone. Still, some manufacturers (usually not mainstream firms) do mention these scores when promoting a new handset.
