It sounds about right to me. For example, I have a Samsung phone that predates the EU agreement by a couple of years and even though it charges off 5V at USB current levels and uses USB for data syncing, the charging/data connector is some proprietary Samsung one and it can't charge from a USB port with the official cable. There's a couple of Samsung connectors, Sony Ericsson had one, Nokia favoured barrel jacks with various oddball voltage and current requirements, and Motorola Razr phones used the mini USB port for charging in a way that was incompatible with everything else. |
