The specifics that enable Apple's proprietary functionality are contained in the proprietary silicon, software, etc. not the schematics. Granted, there are some specifics that could be interesting from a design analysis perspective like the bill of materials (BoM) cost, or the specific choices made in the design (e.g. using a buck regulator IC to improve efficiency, tradeoffs between cost and redundancy, etc...). I maintain that most of the specifics contained in the schematic aren't useful for an engineer designing another phone. An experienced electronic engineer facing the same design problems would make similar decisions regarding which components to use, based on known principles - but that's only if they could access Apple's proprietary chips in the first place. Everything we can see in the schematic could have been generated from a teardown as you mentioned. Not sure what "certain consumers" you're referring to - I imagine the schematics would help repair shops most in knowing what test points to diagnose and what components are involved. Huawei, Xiaomi, et al. don't need Apple's schematics. They have plenty of design engineers of their own, and can't access Apple's chips anyway. The parts that do use market-available chips don't have any critical details that might take away Apple's edge.
