`adb reboot -p` usually reboots instead of power-down which it is supposed to

Question

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?

shell only means it opens a shell first and writes the same there. — JohnyTex, Dec 27 '16 at 13:02
@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. — Grimoire, Dec 27 '16 at 16:23
Yes, what I meant (sloppily) was that the result is the same, right? — JohnyTex, Dec 27 '16 at 17:08

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 Feb 09 '17 at 08:25
@JohnyTex you would have to disconnect your phone just after issuing the command – Timo Schwarzer Feb 09 '17 at 08:37

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. – Andrew T. Aug 08 '23 at 17:23
