    Is there a way to sync a device, any type, just for data and not battery charging ? For example I want to sync my running watch just for data transfer, but I don´t want to charge it and drain Mac battery.

    Not that I know of, since it is transferring data it is going to power the bus on the machine anyways. What do you think data is? It's electricity. It will always use battery power to do read write operations.

    OK. Thought that like some charge /sync cables one could opt only charging or both.
