The simple answer is........no your charger alone can't drain your battery.
Why?
In order for the charger to draw power there must be a compete circuit made. That can only happen when the phone is plugged in and charging. The phone charging circuits will cut off when the phone is full stopping the draw of electricity.
The bare cord plugged in is just that.......a bare inactive cord doing nothing.
