Just another thought,
Before moving to my first iphone (5) with the new power connector I used blackberries. Having a dedicated, secure dock or place to charge your phone goes a long way to avoiding problems with your microusb ports as they tend to be a bit fragile.
I also always stuck some Prestik over my charging and earphone ports to prevent dirt and water incursion.
But again, I'm the guy who bolts the family laptop to the table believing that a laptop is a portable computer and not a computer to be operated on a lap.
So take my opinions from whence it came.
