"Your parents' licence will not cover you while you're away at uni unless you only use a device that's powered solely by its own internal batteries and not connected to the mains."
I'm not at university right now, but it seems like such a ridiculous thing. If they did come banging on someone's doors, if they somehow knew you were breaking this rule, couldn't they just disconnect their appliance (e.g., iPhone)?
The point is that this law seems really trivial. Best case scenario: you have a device with absolutely amazing battery life and you charge it overnight, then watch however many hours of whatever you want covered by your parents' TV license. That could work for a laptop/tablet...
I don't get it. Why bother with such a dumb law?
Is this right?
