just looked into it. you're right, it's just absurdly inefficient. the phone might die in 4 hours of screen on time or so, and with energy going that fast I'm sure it would cause heating problems that may take a toll on the OLED screen and battery longevity. i feel the option should exist one way or another, automatically going to 120 at a certain temperature after a certain duration or something.
