If I remember correctly, battery level was practically the only "offline feature" of the pin. A device whose only working feature is to check its own battery level isn't much use.
If that was the case, they wouldn't need the age-verification for "adult" features, because there would be no "adult" features. Right?
Note: Because of dependency on architecture and system changes to any current version of Apple operating systems (for example, macOS 26, iOS 26 and so on), not all known security issues are addressed in previous versions (for example, macOS 15, iOS 18 and so on).
