How to shift device in Doze Mode (Android Preview M / Marshmallow)?

Question

I followed steps described here:

https://developer.android.com/preview/testing/guide.html#doze-standby

Circumstances:

• Android Debug Bridge version 1.0.32

• Nexus 9 with Preview M

Shell:

$ adb shell dumpsys battery unplug

=> worked, device unplugged

$ adb shell dumpsys deviceidle step

=> Output: Stepped to: ACTIVE

$ adb shell dumpsys deviceidle -h

=> does not work => Output:

Device idle controller (deviceidle) dump options:

[-h] [CMD]

-h: print this help text.

Commands:

step

disable

enable

whitelist

I tried it with:

adb shell dumpsys deviceidle enable

But it didn't work.

So my question, as mentioned above, how to shift the device in Doze-Mode? What did i make wrong?

Answer 1

There is a better way to achieve this in the new releases:

$ adb shell dumpsys deviceidle force-idle

No need to unplug from power, no need to wait for the screen to turn off.

Answer 2

Ok, i got it. The trick was to turn the screen off! After that

$ adb shell dumpsys deviceidle step outputs:

IDLE_PENDING

then

SENSING

then

IDLE

then

IDLE_MAINTENANCE

then

IDLE

then

IDLE_MAINTENANCE

and so on...

Answer 3

Yes, it appears that Google's developer testing guideline is incorrect. I just recently discovered this as well and posted a bug about it here with the correct steps to get the device to idle (aka doze).

Answer 4

You can find my full answer posted on the similar topic here: How to test Doze Mode on Android?

Idle State - In order to put the device into an Idle state you can use the following adb commands:

>adb shell dumpsys battery unplug
>adb shell dumpsys deviceidle force-idle

Active State - In order to put the device back into the Active state you may simulate the following key event:

> adb shell input keyevent KEYCODE_WAKEUP

I also needed a quick option to toggle between Active and Idle states so I wrote a batch script adbIdleModeSwitch.bat for these purposes, you may download and use it: https://drive.google.com/file/d/0B81qFnPX_eUUYTMxOTd1UG94NVk/view

Answer 5

$ adb shell dumpsys deviceidle -h

This command only outputs a help message like common unix program.

IDLE means Doze mode. In the article you linked, you can regard Doze mode as device idle mode.
