Soon after news emerged that Apple admitted to slowing down iPhone performance as the devices' batteries age, multiple lawsuits have been filed against the company.

CNBC reported that Stefan Bogdanovich and Dakota Speas filed a class-action lawsuit in U.S. District Court for the Central District of California against Apple, claiming the company never asked for consent from them to alter the performance of their phones.

The lawsuit says Apple breached the implied contracts with Bogdanovich and Speas "by purposefully slowing down older iPhone models when new models come out and by failing to properly disclose that at the time that the parties entered into an agreement," according to WCBS.

The complaint also says that the two are entitled to compensation because the slowdown of their devices cause them to suffer “economic damages and other harm.”

"Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components," Apple said in a statement to The Verge about performance of the devices.

“Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions. We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future,” Apple said in the statement.

Bogdanovich and Speas are trying to get the case certified to cover all U.S. owners of iPhones older than the iPhone 8, according to CNBC. Their suit is not the only one against Apple since the company released its statement about iPhone battery speed. WCBS reported that a second class-action lawsuit was filed in Illinois on Thursday night.

The Chicago Sun-Times reported that the suit was filed in Chicago by two people in Illinois as well as by Ohio, North Carolina and Indiana residents with iPhone models 5 through 7.

The suit says Apple “needlessly subjects consumers to purchasing newer and more expensive iPhones when a replacement battery could have allowed consumers to continue to use their older iPhones.”

Unspecified damages are being sought in the suit.
