Sony Ericsson has reported its financial results for the third quarter of 2011 and has committed to a smartphone-only future.

Sales were up 33% on the previous quarter to 1.586 billion Euro, although this is slightly less than Q3 2010. Income before taxes was 31 million Euro - half the Q3 2010 figure but a dramatic improvement from the previous quarter’s loss.

The Advertising Standards Authority has upheld a complaint against Sony Ericsson for the phone specifications shown on its website.

The web page for the Xperia X8 smartphone claimed ‘Standby time (up to) 446 hours’ with a note below reading ‘Battery performance may vary depending on network conditions and configuration, and phone usage’. An ASA investigation was launched after receiving a complaint that suggested the standby time for the smartphone was substantially less than the advertised figure.
