When writing:

adb reboot -p

I expect the unit to power down indefinitely. Instead, it just reboots automatically, the same as having written:

adb reboot

only.

Why is that? What should I write?

    From my notes, adb shell reboot -p.

  • shell only means it opens a shell first and writes the same there.

    @JohnyTex Nein, it's not the same. adb reboot -p means execute adb with arguments reboot and -p. adb shell reboot -p means execute a shell on the device, then execute the program reboot with argument -p which resides inside the device. This is the difference.

  • Yes, what I meant (sloppily) was that the result is the same, right?

Many phones start booting when a power cable is attached. This could be the reason here for the phone rebooting instantly instead of staying off.

  • Do know what could be done about that?

  • @JohnyTex you would have to disconnect your phone just after issuing the command Feb 9, 2017 at 8:37

This should work

adb shell reboot -p

    Welcome to the Q&A site Android Enthusiasts Stack Exchange. While this is a valid answer, could you edit and expand on the reason why it works? Otherwise, it's okay.
