By "fully discharged" I mean I can't boot my phone at all, not even to 
the white bq screen. And if I plug the phone to the wall, I have to wait 
several minutes before I can turn it on again. Maybe this doesn't mean 
the battery is fully discharged, but if it doesn't, I don't know how to 
"really" drain it to a "real" zero. How can you do that?

Don't worry, I won't try!
