Key on

On my 03 f150 I need to have the key all the way on just to listen to the radio my question is will this drain the battery?

Yes.
Anytime there is an electrical device in use the battery loses some power if the engine isn't running.
To get to the accessory setting on my 2003, I have to turn the key to the run position then quickly turn it all the way back to accessory.

Are you able to get the key into the accessory position by turning it back instead of forward?

Aftermarket radio? If so, somebody wired it up wrong.

Leaving it in the "run" position drains the battery a lot faster than in the "Acc" position, since the entire electrical system is live when in "run".
