It has nothing to do with the touch screen. I assume it is a current/ compatibility issue between the device/ cable and charger. I had problems transferring data with other devices when using specific cables too.
I've noticed that my Samsung 0.7 output amp charger charges the moto g significantly faster than my lg 1.2 amp charger even though both are 5v. It should be able to take up to a 1.5amp current, any higher will be restricted by the device.
