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.

Try adb shell reboot -p to shutdown the phone.

    For those who wonder what the "p" stands for: it's short for --poweroff :)

    it would have been better unix way: "shutdown" for shutdown and "shutdown -r" for reboot Oct 3, 2013 at 14:22

    Try adb reboot -p (leave out shell).

    reboot -p only reboots my tablet. Doesn't shutdown.

    How did you find out? It's not mentioned in the official doc: developer.android.com/studio/command-line/adb

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
  • 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.

    Doesn't work for me though. Nexus 4 on Lollipop 5.0.1 (rooted, even after using su), or LG P705 on ICS 4.0.3 (unrooted). I wonder if it's related to ADB version or not (mine's 1.0.32).

    Doesn't work for me on an MIUI Redmi 3. "shutdown: not found". Dec 14, 2016 at 3:18
  • This is not a standard command

In Windows Sub-system for Android(WSA) shutdown doesn't work instead try doing

adb shell reboot -p or

adb shell

Try

adb shell "input keyevent 26"

It's work for me.

    That would put the device to sleep mode or would awake it. 26 is keyevent for power key. This cannot shutdown the phone.
