Slow down of loop when servo used

[pelikhan]

Running this program on CPX + SG92R on pin A1,

• on battery, it grinds to a locks within seconds.
• on USB, it slows down to a grind after a minute

#include "CircuitPlayground.h"

CircuitPlayground cplay;

int main()
{
    int status = 0;
    while(1)
    {
        cplay.io.led.setDigitalValue(status);
        cplay.io.a1.setServoValue(30 + rand() % 15);
        cplay.sleep(20);
        status = !status;
    }
}

I don't see it. Do you actually need to have the servo connected?
