A couple of questions about smartphones' performance measurement:

1) Why does AnandTech and other reviewers use benchmarks instead of real games, when testing smartphones' performance? What's wrong with GameBench or similar apps?

2) I found in some review that Injustice 2 played on Galaxy S9+ (Exynos 9810) loads only 7% CPU and 21% GPU. According to other review this game on this model has a limit 30 fps (while 60 fps on Pixel 2 XL), poor graphics and lags. Does it mean game developers do not load processors in full? Why is it so?

Testing real world games is problematic in terms of tooling and repeatability. GameBench is a good effort but it's still inherently very flawed to get empirical data on something. GameBench also doesn't solve the iOS conundrum. As long as real mobile games don't have a built-in benchmarking mode with sufficient repeatability I don't have confidence in publishing numbers through different methods. There are different methods but most require rooting a device which at the time a review should be posted is unfeasible and again iOS is problematic.
