Standby time

Quad Cortex
5

The “Standby” mode is not putting the device into a deep sleep. It seem to switch off the screen and that’s it.

But I guess you need to measure the power consumption on the power supply unit to determinate if the is any significant difference between standby and normal operation without any workload.
@ danimaetrix But so if you observed that the device is getting still warm there will be no real/good standby at all.

For all who let the device 24/7 running - at best with the wifi connection/internet connection: well, congratulation ! you are rich ! :slight_smile:

P.S. these are the CPU speed values (MHz) in standby mode:

# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 
450000
# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq 
450000
# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq 
112500
# 
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies
450000 225000 112500

Also from this point it seems that the cpu will not go down to the lowest frequency in standby mode.
But power consumption is not only a question of CPU - I guess also the rest of the hardware runs full power in standby and will not be powered off.
