Mobile chargers get energy-use rating system

Summary:A group of mobile-hardware heavyweights have joined forces to help cut the carbon footprint of mobile use

LG, Motorola, Nokia, Samsung Electronics and Sony Ericsson have joined forces to launch a common energy-rating system for mobile-phone chargers to alert shoppers which models are the most power hungry.

The system will reveal how much power the charger uses when plugged into a socket after the phone has finished charging, using a star rating: no stars for the most energy-guzzling brands, five stars for those who chug down the least electricity.

The ratings are based on the Energy Star system used in the US, as well as the European Commission's energy standards.

In the short term, the information won't be made available on the chargers at the point of sale and will be confined to each manufacturers' website.

Asked if Nokia plans to limit the chargers shipped with its phones to four-star and five-star models, a spokeswoman for the manufacturer told ZDNet UK's sister site, silicon.com: "We are increasing the number of products with four- and five-star chargers and rolling these out with many high-volume products."
