why 0.80ghz

Why does whenever I have my gaming laptop unplugged the cpu drops to 0.80ghz

Simply put, you'd want to be as efficient as possible when using battery, so lower processor clock would be really helpful for that. You don't want your laptop to suck all of the juice just only for a hour, yeah? And it can potentially increase your battery life as it won't be exposed with heat as much.

 

The Windows power slider have an option from "Battery saver", "Best battery life", "Better performance", to "Best performance". Kind of analyzed of how they works. Battery saver, you guess it, implements the variable clock control of the CPU, even reduces it to at bare minimum of 0.65 GHz when idling, which is really helpful to extend the battery (in my case, would be 1-3 hours more depends of usage), and it reduces the brightness of the screen, lower than the others, which I actually choose for better night-reading. Best battery life, and better performance, I barely use this one, but slightly brighter screen, still with variable clock control (I don't see much difference somehow as I kind of always using it plugged in) . Best performance, when my laptop would be just constantly turboing at 3.1GHz but it kind of helpful for CPU-intensive tasks like rendering.
