When lockdown mode is enabled in Android 15, USB data access will be disabled, preventing potential "juice jacking" attacks.

Points taken from article:

  • Android 15 is adding a built-in mechanism to protect your device from “juice jacking” attacks.
  • Charging will be allowed when lockdown mode is enabled in Android 15, but USB data access will not.
  • Juice jacking is a largely theoretical problem you don’t really need to worry about, but it’s still nice that Android will protect you against it.
