We have managed to get hold of the full specifications of the Sony Xperia P and Xperia U. You can find the full spec list in the Specifications tab at the top of the site. Both the Xperia P and Xperia U will be running on the ST-Ericsson NovaThor U8500 1GHz dual-core chipset.
The Xperia P will have 16Gb of internal storage, 1GB RAM and a 1305mAh embedded battery. The Xperia U will have 8GB internal storage, 512MB RAM and a 1320mAh battery (not embedded). It looks like neither phone will have microSD memory card support from what we’ve seen – although this has to be confirmed.
