Huawei Cheats During Benchmarks
Huawei has been sending out phones with secret benchmark modes to inflate their GPU benchmarks. The phone detects the benchmark being run, and sets the SoC to operate at full throttle, going well past its thermal envelope. The cheat was uncovered by using identical private versions of benchmarking software, which hide their names and identifying details. During the legitimate test of a phone running a Kirin 970 SoC, it drew an average of 4.39W, but during the doctored test, it drew 8.57W. It also managed to nearly double its benchmark scores. At all other times, the phone operates as normal. Temperature is a problem for phones, where chips can overcome the limited cooling; most phones almost never run at full-tilt during normal use.
