The manufacturers of mobile phones creates CPUs and GPUs that are optimized to win benchmarks but if you rerun the tests over a longer time period the CPU&#x2F;GPU will overheat and run into thermal throttle issues. Thus consumers are thinking they are buying a phone which is faster than what they really get in practise.<p>Then marketing wants new features to sell to consumers so you increase the core count which is one way of making the phone faster but at the same time you drain the battery a lot faster.
