i got my console day one, along with a charge and play pack, and i had the same issue start happening within a couple months - sort of.
for me, if the charging plug is hanging with some tension (as in if i am holding the controller a couple feet above the group while it's plugged in, or if i have it set on the edge of a table with the cord hanging off the edge) it will charge (orange light), but if i set the controller down and the cord no longer has any downward tension the light will immediately switch to white and stop charging. there must be a loose connection in the charging port but i can work around it so i never bothered with a warranty swap.
try to jiggle the plug around once you hook it up to your controller and see if the light turns orange.
and yes, late reply, but i don't get on the forums much...
