A new Universal Charging Solution (UCS) has been approved by the International Telecommunication Union (ITU), a division in the United Nations, according to a Thursday report. The energy efficient charger will be compatible with all cellphones regardless of make and model, with certain unnamed manufacturers already incorporating the standard into their products, the ITU says. Other than the energy savings, the new charger will also help eliminate waste as the charger can be retained as new phones are upgraded and older ones are thrown out.
