When using Futaba BLS 451 servos for example these are very modest. Savox 1258/Align DS610 are much more demanding, one alone taking up to 15Amps peak for the instance of a second. And for very extreme example take high voltage Savox servos SB-2271SG HV. They demand up to 27Amps (1 Servo!) peak which you can see when measure the power consumption with an oscilloscope.

On the other hand it is a very good practice, when using such high power servos as mentiond above, to decouple the servo power completely from receiver and microbeast and use a regulator as power supply or some kind of power bus/power distribution system (which simply may be connecting the power wires from the servos directly to the battery). So voltage loss and internal resistance are reduced to a minimum (the higher the current and the higher resistance, the more voltage you will loose!).
