Sony Corp. has unveiled new mobile devices that also function as displays for PlayStation games, as it adds features to win sales in a market dominated by Apple Inc. and Samsung Electronics Co.

The marquee Xperia Z3 smartphone is waterproof and comes with a battery that can stay charged for two full days of active use, Sony said on its website.

The company also announced the Z3 Compact smartphone with a 4.6-inch screen and an 8-inch tablet computer.

Chief Executive Officer Kazuo Hirai has been pushing his One Sony plan to better integrate the company¡¯s electronics and entertainment assets to revive earnings. The PlayStation 4 has been one of the few bright spots for Sony, outselling Microsoft Corp.¡¯s Xbox One, amid a decade of television losses and lackluster demand for Xperia smartphones, which barely crack the top 10 globally in shipments.

¡°Allowing its latest smartphone and tablet remote access to its PS4 and games played on its PlayStation network is another huge step in the right direction,¡± Amir Anvarzadeh, a manager of Japanese equity sales at BGC Partners Inc. in Singapore, said. ¡°The Japanese consumer electronics giant is moving away from the past strategic mistakes of focusing on market share gains.¡±

Sony is forecasting its sixth annual loss in seven years and Hirai cut the company¡¯s full-year smartphone sales projection to 43 million units from an earlier forecast of 50 million.
