**Example**: **Example**:
`obsdfreqd -m 100,50 -r 40` will start the daemon, when power is plugged in, maximum frequency is 100 and threshold is 40, on battery the threshold is 40 and the max is 50. `obsdfreqd -T 90,65` will start the daemon, when power is plugged in, maximum temperature is set to 90°C and 65°C when on battery.

If CPU usage <= `threshold`, reduce frequency by `downstepfrequency` down to `minfrequency` every `timefreq` milliseconds when `inertia` reached 0. `inertia` lose one point every cycle the CPU usage is below `threshold`. If CPU usage <= `threshold`, reduce frequency by `downstepfrequency` down to `minfrequency` every `timefreq` milliseconds when `inertia` reached 0. `inertia` lose one point every cycle the CPU usage is below `threshold`.
When flag `-T` is used, if the temperature exceeds the defined limit, the `maxfrequency` is decremented every cycle. When the current temperature is below the limit, the frequency limit is incremented at every cycle.
When switching from/to battery, values switch to mode specific when user defined. When switching from/to battery, values switch to mode specific when user defined.
