That is not the cable's fault -- more likely, it must be a 'dumb' charger. USB devices per default get 100mA from the host, but can request to get the full 500mA. When you plug your phone into a pc, it should be able to negotiate for that, but some (esp. car) chargers don't 'listen' to the USB. So if your phone consumes ~100mA at idle, there's your reason.
