Lockdown mode in Android 15 protects your phone from 'juice jacking'

www.androidauthority.com

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.

You certainly don't want anyone jacking your juice without permission.
- That’s why I use a USB condom.
  
  Just in case you are joking (or people think you are) those do exist. Basically a dongle with only the power pins on each end.
- Not necessarily, if you find an exploit that allows you to install malware without user interaction, Mactans famously did that for an older iOS version.
  I'd still argue that making good use of such an exploit and rolling out the necessary, physical infrastructure does not have a great cost/reward ratio.
  
  Why? I have never heard of this happening
I don't use my phone for that, I swear!
This can also be practical in places where the police can force you to unlock your phone with biometrics but not with the PIN.
Ever since I've seen the police here force people to delete the videos of them abusing citizens, I have been very wary of biometric identification.
So far my 'emergency' procedure would be to restart my phone, as it's asking for a PIN after a reboot.
LineageOS has been doing this for a year or so already.
- Same on GrapheneOS :)
- It’s smart! Do not expose logic without first supposing an appropriate level of trust. Software can have errors.
- Pixel UI seems to have it too, but does that not prevent data transfer?
How is this different from current Android
- Lockdown mode was introduced in 2018’s Android 9 Pie release as an optional feature users could add to their power menu. When enabled, lockdown mode hides notifications and disables all forms of authentication except for the user’s primary authentication (PIN, password, or pattern). In Android 12, Google made the lockdown mode toggle appear by default in the Android power menu, though some OEMs hide it or offer their own, similar version of the feature elsewhere.
  Android 15 will further restrict USB access in this mode to help defend against attacks.
  
  Don't you already need to unlock the phone to change USB protocol?
