How can I shutdown my Android phone using an adb command?

Question

How do I halt an android phone using adb command? I can reboot, but I don't know how to halt.

I tried shutdown -k wait command, but it did not work.

Answer 1

Try adb shell reboot -p to shutdown the phone.

Answer 2

Note: All the following commands below require root access.

On Android Oreo, this works and does a graceful shutdown:

adb shell su -c 'am start -a com.android.internal.intent.action.REQUEST_SHUTDOWN'
adb shell su -c 'am start -n android/com.android.internal.app.ShutdownActivity'  #alternative; the aforesaid intent is supposed to be passed to this component under normal circumstances, but calling the component alone works too
adb shell su -c 'svc power shutdown'       # alternative; tested on Android 5.0, 6.0.1 and 8.1.0

Following is an alternative and is tested on Android 4.2, 5.0 and 6.0.1. I do not know about Nougat but it doesn't work for Oreo though.

adb shell su -c 'am start -a android.intent.action.ACTION_REQUEST_SHUTDOWN --ez KEY_CONFIRM true --activity-clear-task'   # I kept this here for historical purposes only.

For low-level and instant shutdown

If you're running Android KitKat or above^* and have root access, you can try this command:

adb shell su -c 'setprop sys.powerctl reboot,recovery'

• replace su -c with adb shell to run the command using adb
• replace reboot,recovery with reboot to reboot the device
• replace reboot,recovery with shutdown to shutdown the device

^* _{The last version on which the command is tested upon is stock Android 6.0.1.}
