Environmental sizing of smartphone batteries

摘要: Smartphone use has increased at a phenomenal pace worldwide. In 2011 more smartphones have been sold than desktop pc's, notebooks, netbooks and tablets together. The total worldwide smartphone sales reached 472 million units in 2011, 149 of them were the fourth quarter 2011. is, like almost every other mobile device, powered by batteries, limited size therefore capacity, which makes energy management paramount. While global demand devices continuously expands, density batteries grown an insignificant rate, but period still decreases because high loads big screens. this paper we studied power breakdown five on sale We defined three different user profiles for “heavy”, “moderate” “light” users can state that theoretically it is sensible to re-size battery based profile. keeping acceptable decrease capacity moderate light with 25%, reducing needed product 2.1 3.4PJ per year. practice aging will result decreasing over its life. When taking into account most comply only resizing strategy sensible. This 20% all producing 0.5 0.9PJ.
