Potential 20pct Smartphone Battery Life Improvement With New Memory [news.bbc.co.uk]

Smartphones could have their battery life extended by up to 20% by changing what type of memory they use. Samsung has announced plans to produce memory modules built of what is known as a phase change material. These modules are built of a substance that records or erases data when it is heated and typically use far less power than existing equivalents. Samsung said modules made of the memory material would roll off its production lines later in 2010.
