According to source of CNET an HTC spokesperson said that,” Thank you for your email about the HTC One (M8). Benchmarking tests to determine maximum performance of CPU and GPU, and similar to the engine in a high performance sports car, our engineers optimise in certain scenarios to produce the best possible performance.
HTC confessed that its HTC One M8 scored varied results in two different AnTuTu benchmark test tools. This lower score mode aims to combat ‘cheating’ techniques used by manufacturers. Users of new mobile now can activate this mode using a toggle within the semi hidden developer tool of Android.
It also added, “For those with a need for speed, we’ve provided a simple way to unleash this power by introducing a new High Performance Mode in the developer settings that can be enabled and disabled manually. The HTC One (M8) is optimized to provide the best balance of performance and battery life, but we believe in offering customer choice, as there may be times when the desire for performance outweighs the need for battery longevity.”
