does the length of a cable affect the time it takes to charge a device?

Hello,

I am having a discussion with a co-worker in regards to charging cellphones. With the emergence of Fast charging home/car chargers will the length of the cable affect the time it takes to charge a device?

for example:

let's say a 4ft cable with fast charger will charge to 100% in 45 min.

would a 15 foot cable charge in the same time or would it take longer?

my assumption is that it should take the same amount of time because the difference in the cable is irrelevant due to the speed at with the power is flowing.

I apologize if this is a noob question but it has peaked my curiosity..
