The French agency in charge of competition, consumer affairs, and fraud prevention (DGCCRF) has issued a 25 million euro fine against Apple for failing to warn owners of older iPhone models that updating the operating system would result in slower operation.

In January 2018 the agency began investigating concerns that updating older iPhones to iOS 10.2.1 and 11.2 would slow the operation of the devices. The new operating systems include dynamic power management programs which adversely affected the batteries of iPhone 6, SE, and 7. Once the operating system was updated, it could not be reverted to a previous version, leading to some users having to either replace the batteries or to purchase newer phones.

The DGCCRF held that withholding this information from consumers “constituted a misleading commercial practice by omission.” Along with the fine, Apple is required to issue a press release about the matter on their website for one month. Apple has accepted the fine, and in a statement said they were “happy to have resolved” the situation.
