California, Dec 22: Two iPhone users have filed a lawsuit against Apple (AAPL) after the technology giant admitted to slowing down their older phones for ‘optimal performance’. The plaintiffs, both users of iPhone 7 brought a class action lawsuit in California on Thursday, reports claimed.

The duo claimed that Apple never sought permission from them before slowing down their phones. They are also reportedly trying to get the case certified to cover all people in the United States who owned iPhones older than iPhone 8.

Stefan Bogdanovich and Dakota Speas also claimed damages from Apple as they allegedly suffered economic damages and other harms for the company’s action, MSN claimed.

Reportedly Apple has not commented on the issue yet.

Apple has confirmed what some conspiracy theorists suspected, that it intentionally slows performance of older iPhones as batteries weaken from age.

The admission played into concerns that Apple was stealthily nudging iPhone users to upgrade to newer models by letting them think it was the handsets that needed replacing and not just a matter of getting new batteries.

“Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices,” an Apple spokesperson said in response to an AFP inquiry.
