Root Setcpu settings

At 900/900, threshold is pretty much useless to mess around with.

Up/Down thresholds control the CPU scaling based on load. Lets say you had it set to 900max and 480 minimum. Up threshold would (depending on the scaling rate) be the threshold of CPU usage before it goes up to the max frequency. Down threshold is the opposite.

So 50up would mean when your phone is using 50%CPU capacity at that point, it will scale up to 900 from 480, and when you start getting down to 25% or less it will scale back down to 480 from 900.

It's basically how you can balance performance and battery life, but with the minimum and maximum frequencies the same it's useless.
