Never heard of the burn in. I hanged my navigation buttons to look like lollipop. There is a theme.
I've read the quick charge 2.0 is supported on the z3. You'll need a 2.0 charger and it only works using the usb port, not the mag port.
With the long battery life, I don't have a need for quick charge. I like having the mag chargers so I don't need to open the USB flap.
