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 :) – Izzy Jun 26 '13 at 7:15

    it would have been better unix way: "shutdown" for shutdown and "shutdown -r" for reboot – Mert Akcakaya Oct 3 '13 at 14:22
  • Doesn't work for me though. Nexus 4 on Lollipop 5.0.1 (rooted), 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). – Andrew T. Jan 30 '15 at 5:48

    Try adb reboot -p (leave out shell). – Caleb Xu Mar 9 '15 at 1:07

    reboot -p only reboots my tablet. Doesn't shutdown. – JohnyTex Dec 27 '16 at 13:03

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.

  • "setprop sys.powerctl reboot,recovery" worked for me. Thanks! – spica Jan 17 at 3:35

  • Doesn't work for me on an MIUI Redmi 3. "shutdown: not found". – andrew lorien Dec 14 '16 at 3:18
  • This is not a standard command – Rolf Jul 6 at 16:23
