I am using IMX8 EVK 

flashed Android 11 on SD card, and testing suspend to RAM

device enters suped to RAM and exit OK

but power meaasurments are very hugh (X10 then expected)

according to measurments board 2 HDMI inputs phy are on even in suspend to RAM

1. please advice how to disable that

2. please indicate if Android 11 default image should reach the datasheet suspend to RAM power consumption performance

1. how can I reach lowest power in suspend to RAM using Android + IMX8PEVK? 

2. I think most power consumption is due to HDMI PHY, how can I shut it down before going to suspend to RAM?

Hi גנור

higher power consumption may be due to leakage, may be recommended to look

at AN13249: i.MX 8QuadMax Current Drain with Low- and High-Power Use Cases

>2. please indicate if Android 11 default image should reach the datasheet suspend to RAM power consumption performance

no
