The Sony Xperia S (coming to Europe in March), which will go by the name Xperia Ion when it comes state-side in the second quarter, just had a couple of interesting features revealed that were not shared before at the CES demonstration. Along with the regular gamut of high-end features like a 720p display, a 1.5GHz dual-core CPU, and a 12-megapixel Exmor R camera, the phone will also boast a "dirt-repellent - UV-active nano-coating" and a newly advanced fast-charging system for the battery. Here's a quote from the AndroidCentral article with more details on this new fast-charging system,

The product manager also reportedly spilled a few details on the new battery tech employed by the Xperia S. The phone is said to use improved lithium-polymer technology that's capable of recharging in half the time taken by earlier models, with ten minutes of charging time apparently being enough to power the device for a whole hour.
More and more, these new Sony phones are beginning to look pretty impressive. They are packing in a ton of powerful features, they have a slim and elegant design, and Sony has, so far, held to its commitment to update their phones to the newest version of Android far more quickly than in the past, and even faster than several of their competitors sometimes. Is Sony worth a new look in 2012?
