How many cellphone battery chargers do you have lying in drawers at home? Every time you buy a new model you need a new charger because no two models seem to use the same type of charger. You would think that since the manufacturers are able to invent such incredibly smart devices they could manage to develop a universal battery charger.
However there is hope. An article in The Guardian claims that mobile manufacturers have actually agreed to implementing a universal battery charger enabling us to use the same lead even if we change model. This is part of a wave of "green" measures announced at the Mobile World Congress being held in Barcelona. Other new features will include devices with solar panels and devices made from recycled material.
