MicroUSB is good for USB connection but really lousy for charging the device. As it happens you need to charge modern phones almost daily so the connector is subject to extra wear and possible bending/breaking...

A while back I learned that repair shops have a list price for repairing damaged microUSB ports, as it seems to be the top contestant for repair, the other being of course fixing broken iPhone displays

What I'd like to see is a sturdy enough connector for charging only, standardized for all handhelds, or wireless charging.
