Apple recently said that it's going to be more transparent about iPhone battery health with the iOS 11.3 update, telling users when they need to replace their battery and letting them disable the performance throttling that's landed the company in hot water. That's not the end of this saga, though.
The US Department of Justice and the Securities and Exchange Commission are investigating Apple about its updates that slowed performance on iPhones with older batteries. Sources speaking to Bloomberg say that the agencies are looking into whether Apple violated securities laws regarding disclosures about its updates that throttled older iPhones.
So far, the DOJ and SEC have requested information from Apple. Because the investigation is still early, it's unclear if the agencies will actually take an action against Apple.
Apple apologized for not being more clear about its actions after the news of its performance-throttling updates came out, but we've still seen class action lawsuits and now this investigation come out. The good news is that Apple will be more transparent about iPhone battery health and performance in the future, but for now, it'll have to deal with the DOJ and SEC.
