Question-Reverse tactile button

00:45:27

If the LED is off, will it drain the battery?
(Power supply is a regular cellphone battery)
Since the current is still flowing, im not really sure,
Im sure it will be better for me to use a a switch with a "normally closed function". 
i was just curious about transistors , maybe if i remake this circuit and let no current pass through maybe it would solve my problem. But still i wanted ask if you guys know the answer. Thanks in advance

Yeah it will drain the battery because the the resistor is a voltage drop
