Mobile World Congress: Sony comes out fighting with new smartphones

Sony stole a march on its competitors on the opening day of Mobile World Congress in Barcelona with the launch of three new smartphones and a complementary earpiece.

The Japanese company — which has fallen behind the likes of Apple, Samsung, and HTC in the smartphone game — came out fighting at the technology conference with its range of Xperia X handsets.

Users will be particularly keen to see how the “smart battery” technology, which Sony claims can deliver up to two days battery life stands, stands up to scrutiny.
