Connect your Android device over adb to get adb shell and check the default screen timeout value already set,
$ adb shell settings get system screen_off_timeout 30000
As you can see above for our android device the default screen timeout was set to 30 sec i.e. 30 * 1000 ms, now we can change this value to say 45 sec as,
$ adb shell settings put system screen_off_timeout 45000
The display information can be obtained using below command,
$ $ dumpsys power | grep Screen mLastScreenBrightnessBoostTime=0 (3088734 ms ago) mScreenBrightnessBoostInProgress=false mSuspendWhenScreenOffDueToProximityConfig=false mDozeAfterScreenOff=true mMinimumScreenOffTimeoutConfig=10000 mMaximumScreenDimDurationConfig=7000 mMaximumScreenDimRatioConfig=0.20000005 mScreenOffTimeoutSetting=45000 mMaximumScreenOffTimeoutFromDeviceAdmin=900000 (enforced=true) mScreenBrightnessSetting=0 mScreenBrightnessModeSetting=1 mScreenBrightnessOverrideFromWindowManager=-1 mDozeScreenStateOverrideFromDreamManager=1 mDozeScreenBrightnessOverrideFromDreamManager=17 mScreenBrightnessSettingMinimum=1 mScreenBrightnessSettingMaximum=255 mScreenBrightnessSettingDefault=102 Screen off timeout: 10000 ms Screen dim duration: 2000 ms
As you can see above, if we change the “screen_off_timeout” to 45 sec, it changes as “mScreenOffTimeoutSetting=45000” as reported in dumpsys.
