Some users say they have already lost 15 per cent or more of their capacity after less than a year of owning the phone.
Joanna Stern, a personal technology columnist at the Wall Street Journal, said that her phone had already reached 88 per cent battery capacity. She said that she had been told by the Apple Store that her heavy use of the iPhone meant that it had already hit 450 charge cycles – which would represent heavy use of the kind that Apple says can reduce the iPhone’s battery life.
Ms Stern was not alone in her complaint: on Twitter, a number of posts in response to hers and others suggested that other users were surprised by how quickly their battery’s capacity had declined. But others still indicated they were seeing performance in line with previous years, and so it is difficult to know whether there is a problem with this generation’s iPhones more generally.
