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...
