How to enable Stay awake in the developer options using ADB?

Question

I'm trying to find a way to enable the Developer options -> Stay awake option via ADB. The solution that I found was to find a way to open developers option menu and then enable stay awake option using setevent command in ADB.

Now I'm trying to find the command that will open the developers options. I found the command that opens display options:

adb shell am start -n com.android.settings/.DisplaySettings

So I think that a similar command that opens developers options exists.

I will also be glad to hear about another way to enable stay awake option via ADB if there is any.

your way is a little cleaner then mine :) – Decalcify

The command does not work on my Android 9 device (Sony). Activity class {com.android.settings/com.android.settings.DevelopmentSettings} does not exist. – Recidivate

Answer 2

You can enable Stay awake option without having to use UI with the following command:

adb shell settings put global stay_on_while_plugged_in 3

Where is this settings database stored? – Matherly

Its stored in /data/system/user/0/settings_global.xml – Crenelate

found it was missing an "s" on "user" - /data/system/users/0/settings_global.xml – Propaganda

Then how do disable it? – Jaquelynjaquenetta

@Jaquelynjaquenetta Set value to 0 to disable it: stuff.mit.edu/afs/sipb/project/android/docs/reference/android/… – Imperator

Answer 3

OK, I found a way:

adb shell am start -S com.android.settings/.Settings\$DevelopmentSettingsActivity

I used this : https://github.com/android/platform_packages_apps_settings/blob/master/AndroidManifest.xml

to find the name of the Activity I needed.

Now I have to figure out how to choose the stay awake option by createing a touch event or something...

Set the 'keep awake while plugged in' setting.

adb shell svc power stayon true

This work on my RedMi Note 5 (Android 9) device, thanks. – Counter

Works on Android 11 (Sony Xperia 10 iii). The 'Stay awake' slider in the 'Developer options' menu changes when this command is issued (from the PC). – Fu

To check the state of the setting, use adb shell dumpsys power | grep 'mStayOn=' – Fu

When toggling mStayOn, also other settings under adb shell dumpsys power change. From my expierience they are mStayOnWhilePluggedInSetting, mUserActivitySummary and mLastSleepReason – Fu

Answer 5

Okay I know it is not what MiSo was asking but I think it may be relevant, I have created an app that will enable/dissable this 'Stay awake' setting as you connect/disconnect ADB.

The code is available open-source here: ABD-Stay_Awake
