Sony Xperia S repels dirt and recharges fast27
What wasn't listed with the specs is the fact that Sony told Swiss web site PocketPC.ch that thanks to the phone's "UV-active nano-coating," the Sony Xperia S repels dirt and also protects the device from the everyday wear and tear that a smartphone faces. Another feature on the Sony Xperia S is the improved lithium-polymer technology that allows the device to charge in half the time of a regular battery. Just 10 minutes of charging time will get the Xperia S up and running for 1 hour.
The Sony Xperia S will be launched overseas in the second week of March with its U.S. cousin, the Sony Xperia Ion, rolling out in the second quarter.
