Android Device Idle Mode Not Reducing Current Consumption on i.MX8M EVK

[rohannathi]

Hi NXP Team,

I am working on Android and trying to use Device Idle Mode to observe a significant reduction in current consumption. To measure this, I am using a USB mA meter.

I executed the following commands:

evk_8mm:/ # dumpsys deviceidle force-idle
Unable to go deep idle; not enabled

evk_8mm:/ # dumpsys deviceidle enable
Deep idle mode enabled
Light idle mode enabled

evk_8mm:/ # dumpsys deviceidle force-idle
Now forced into deep idle mode

However, I am not observing any noticeable drop in current consumption on the board.

Could you please advise if I am missing any steps or if additional configuration is required to achieve measurable power savings?

Thank you.

Hello @rohannathi 

I hope you are doing very well.

Could you please clarify how you are connecting the USB mA meter?

Also, you can refer to the i.MX 8M Mini Power Consumption Measurement, Application Note, Rev. 0, 04/2019 in chapter 3.5. Measuring points on EVK platform.

There is explained the way that the EVK was measured.

Best regards,

Salas.
