The Xperia Z-series has never been a big sales generator, and considering the laughable state of Sony’s mobile business, it’s no surprise that the company has decided to kill off the series. Sony confirmed as much on Wednesday when it announced that last year’s Xperia Z5 will be the last Z-series smartphone that it releases. All of the company’s future smartphones will be released through the X-series, with the Xperia X Performance replacing the Xperia Z6 as Sony’s flagship smartphone for this year. The company has also decided to put more focus on releasing smartphones with superior battery life and camera performance.
