Two lawsuits have been filed against Apple on Thursday by plaintiffs in California and Illinois, who argue that the company did not have consent to slow down their iPhones, according to multiple reports.

Background: The legal challenges come after the company admitted, under specific circumstances, it does reduce performance on devices. However, it said the practice is necessary to avoid total device shutdowns on devices with underperforming batteries. The acknowledgment came after a Reddit discussion was followed up with a benchmarking firm confirming something amiss in its testing.

What's happening: The plaintiffs claim they are entitled to various forms of compensation, per the Guardian. They are also reportedly seeking class action status, along with owners of Apple smartphones older than the iPhone 8 in the country who found similar issues.
