Depending on exactly what you mean there can be reasons why you would wish to fly at reduced throttle.
1. It is always useful to have a significant power 'reserve', for instance to ensure the take off is positive and the run reasonably short.
2 The amps being taken from the battery and thus flight duration is proportional to throttle. The less throttle you use the longer the flight.
3. More power means more heat generated in the motor, ESC and battery. At continuous full power the cooling of the motor and ESC may be an issue, particularly on a really hot day.

As solentlife says the correct selection of ESC and battery that matches the power requirements of the motor and its prop will make throttle 'position' just a matter of how you want to fly.

The only way to be sure everything is operating within its specification is to use a Watt meter.
