Nexus 5 won't go into doze mode using ADB

Question

I have a Nexus 5 that won't go into Doze/IDLE mode using ADB commands from Windows. It's adb connected using USB cable and it is working for all other ADB commands. The screen is off.

C:\>adb shell dumpsys deviceidle force-idle
Unable to go idle; stopped at ACTIVE

C:\>adb shell dumpsys deviceidle enable

C:\>adb shell dumpsys battery unplug

C:\>adb shell dumpsys deviceidle step
Stepped to: ACTIVE

C:\>adb shell dumpsys deviceidle step
Stepped to: ACTIVE

C:\>adb shell dumpsys deviceidle step
Stepped to: ACTIVE

C:\>adb shell dumpsys deviceidle enable

C:\>adb shell dumpsys deviceidle force-idle
Unable to go idle; stopped at ACTIVE

Answer 1

First you need run this command:

> adb shell dumpsys battery unplug

Then turn off the screen (this step is crucial), otherwise the device remains in ACTIVE state.

After that run this command until the device state changes to IDLE:

> adb shell dumpsys deviceidle step
Stepped to: IDLE_PENDING
> adb shell dumpsys deviceidle step
Stepped to: SENSING
> adb shell dumpsys deviceidle step
Stepped to: LOCATING
> adb shell dumpsys deviceidle step
Stepped to: IDLE

Answer 2

There may be a condition which prevents the phone from going into IDLE, such as a scheduled alarm clock. Make sure there are no alarm clock apps set to go off in less than an hour of you trying to force the phone into IDLE.
