I just came across a new energy efficiency rating system that the top 5 cell phone manufactures have come up with to rate their chargers. Apparently 2/3 of the energy used by consumers for their cell phones actually occurs when the phone is charging in but the charger is left plug in to the wall. This no-load consumption is where most of the energy use comes from.
According to this new rating system, anything under 0.03W gets a 5 star rating (very efficient). So I was just wondering if anyone new what kind of no-load consumption Blackberry chargers draw. Might be a good idea for RIM to comply with the big manufacturers on this.
Right, I know it stops charging when the battery is full, but what about when you leave the charger plugged into the wall without the phone attached? It draws some kind of power, just not sure how much.
