The U.S. Federal Communications Commission (FCC) briefly published a 163-page document containing electrical schematics for the iPhone 16e, despite Apple’s formal request to keep the information confidential.
The publication occurred over the weekend in the FCC’s equipment authorization database, where the documents covering iPhone 16e models A3212, A3408, A3409, and A3410 were available before being removed. Before their removal, the files were mirrored by the website fccid.io. It is believed that the leak was likely caused by a filing error from a certification body or lab. Metadata associated with the filing indicated that both short-term and permanent confidentiality were marked as “no,” contrary to Apple’s submitted letter requesting privacy for the schematics and block diagrams. This setting is believed to have triggered the automatic publication of the documents.
For typical iPhone 16e users, the leak is not considered a significant issue. However, the information is valuable for hardware researchers and independent repair shops. The schematics provide detailed board-level information, including antenna locations, connectors, test pads, and hidden traces within the logic board. The documents also show how Apple routes signals between major chips and the layout of test and debug pads.
This level of detail can assist with fault tracing and board-level repairs. It may also help security researchers identify potential hardware-based attack surfaces. As of this report, neither Apple nor the FCC has issued a public comment regarding the incident.
