Two large shareholders have urged Apple to study whether iPhones are proving addictive for children and that intensive use of the smartphones may be bad for their mental health, Bloomberg News reported Monday.
"There is a growing body of evidence that, for at least some of the most frequent young users, this may be having unintentional negative consequences" on their health, said Jana Partners LLC and California State Teachers' Retirement System (Calstrs) in a letter sent to Apple dated January 6.
The "growing societal unease" over the intensive use of smartphones by children is "at some point is likely to impact even Apple", they warned, according to Agence France Presse.
The two shareholders, which between them own about $2 billion in Apple shares, called on Apple to develop additional means for parents to restrict the use of mobile phones by their children.
They said confronting this issue now would enhance the value of the firm in the long-term for all shareholders.
Bloomberg said an Apple spokesman declined to comment on the letter, which was first reported by the Wall Street Journal.
Apple already provides parental controls on iPhones that allow restricting access to certain apps and content, AFP said.
The letter represents a new source of pressure on Apple, after being forced to apologize last month for slowing down the performance of older iPhone models.
