Its a bit of both. If the data pins are shorted facing the device (so that the device detects its own outgoing signal on the incoming pin) it will consider the port a dumb charger port and attempt to charge from it based on the cable quality. If there is a proper port response, and the port claim to be a charging port, the device can ask for more than 500mA in increments of 100mA. There will be limitations depending on there being ongoing data traffic or not. |
