Dynamic, Durable, and X Mode are the standard operating modes for ROG phones

The first option is the default, evenly balanced choice between endurance and performance.

In order to get the most battery life out of the 6,000 mAh capacity, the second will limit performance.

The latter will maximise performance by utilising the internal vapour chamber and Asus' 

expertise in maintaining things (though we do suggest attaching an AeroActive Cooler to it). 

The ROG Phone 7 Ultimate could not respond to the 3DMark Extreme Stress Test in X Mode. 

It did become really hot, but it resisted throttling. This is obviously the worst case scenario because the 3DMark test is designed to.
