How to enable High Performance Mode on HTC One M8

It’s simply a mode that is as tuned as possible, it’s also VERY power hungry so it’s not recommended for regular use.

First you need to enable Developer options. Then just open Settings > Developer options, where you have High Performance mode.  If you have any power saver mode enabled, you MUST disable that first. Your benchmarks will now score a little higher.

And, do know that it disables ANY power saver mode.

And yes, it works on One M7 running 4.4.x/sense 6 as well.
