In more recent models (starting with the iPhone XR), Apple displays non-removable warnings if the battery, display, or camera is replaced by a third party.[222] Additionally, features are disabled upon detection of a "non-genuine" replacement such as disabling true tone or hiding the battery health feature. iFixit notes that a proprietary, cloud-linked System Configuration tool is required to "complete" a part repair, meaning that even replacing a genuine part with another genuine part will fail Apple's "genuine parts" check unless said tool is used.[223]
