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.

For those who wonder what the "p" stands for: it's short for --poweroff :) – Izzy Jun 26 '13 at 07:15

it would have been better unix way: "shutdown" for shutdown and "shutdown -r" for reboot – Mert Akcakaya Oct 03 '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 05:48

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

How did you find out? It's not mentioned in the official doc: https://developer.android.com/studio/command-line/adb – minipif Jan 22 '19 at 01:22
so strange on my lg g5 i have to do adb shell reboot -p. if i do adb reboot -p it just reboots and ignores the flag. – j2emanue Mar 26 '19 at 09:40
works fine on a nokia 6.1 running android 9 without root. at first glance I thought that it just rebooted because of the splash screen immediatly showing, but it was the "charging" mode that automatically booted up since the phone is plugged for adb. – XioRcaL Apr 15 '19 at 08:01
Google Glass XE23 doesnt power off with the button as some docs indicate so I needed this to power off for storage. Thanks! – rainabba May 22 '20 at 20:02

Seems to power off immediately, no graceful shutdown(?). – Golar Ramblar Jul 31 '21 at 19:13
Does not work for my phone with AOSP rom on Android 10 unfortunately, seems to be model, adb version or Android Version related? – phrogg Sep 20 '21 at 14:28

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.}

"setprop sys.powerctl reboot,recovery" worked for me. Thanks! — spica, Jan 17 '19 at 03:35

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

adb shell reboot -p or

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. – Firelord Jan 10 '23 at 07:37
