It’s quickly becoming common knowledge that the efficiency of a charger plays a big role in the energy consumption of a device. Energy Star makes this very clear, and so does Motorola's history in making efficient chargers for cell phones.
According to Reuters, "The [cell phone] industry has become the world's top consumer electronics business by volume." That means the energy wasted by crummy chargers is significant. And the industry's manufacturers need to step up and fix this issue.
The five biggest cell phone makers are finally taking notice that this might just make a difference on cell phone sales during the recent slump. So, they’ve come up with a common energy rating system, making it easier for customers to comparison shop when it comes to efficiency and minimizing energy costs. The new system is pretty basic. It works with five stars, five being the most efficient. The companies leaping on to this rating method include Nokia, Samsung, Sony Ericsson, Motorola and LG.
If left plugged into the socket, chargers continue to use electricity even if the phone is disconnected. Nokia said around two-thirds of the electricity used by mobile phones is wasted this way. "If the more than three billion people owning mobile devices today switched to a four- or five-star charger, this could save the same amount of energy each year as produced by two medium sized power plants," Nokia said in a statement.
While the rating system likely won’t mean a heck of a lot at first for consumers – touch screen versus keypad is a bigger deal to most shoppers right now – it certainly will make a difference as people penny pinch more and more on their electric bills. It’s a short matter of time before charger efficiency is as important to consumers as battery life for talk time or camera quality.
