Feminists have hit out at Apple for focusing on bigger iPhones, saying they are not suitable for women's hands.
The smartphone giant released three new handsets earlier this week, discontinuing the final remaining four-inch model.
Caroline Criado Perez, a female rights activist took to Twitter to voice her frustration, calling for Apple to "design for our bodies."
Ms. Perez added that Apple has "failed to update the only phone that fit the average woman's hand."
