85 per cent of iPhone owners who’ve updated their phones have never used Siri, according to new research — and those that have are divided on whether Siri lives up to Apple’s promises. That number is based on a survey of 2,330 Apple-owning folk in the US who have upgraded to iOS 7, the latest software for iPhone and iPad. Analysts Intelligent Voice carried out the survey to find out if Apple had oversold the capabilities of Siri. 46 per cent of a group that had used Siri stated it was a disappointment, while a separate group was also divided on Siri’s accuracy. iOS 7 adds new voices and new languages for Siri, a voice-activated personal assistant. In theory, Siri is supposed to understand a range of questions and commands in order to carry out tasks on your phone — such as calling someone, or tweeting — and find out information for you.
