Newbie question about display on power off mode...

| Hi all,
If any mobile when it is switched off and you connect the charger, it shows
the charging icon on charging.
Can anybody tell me what is the technology behind this. I think on
switching off the mobile, the Operating System will not be shut down and it
will go to a state where only critical components are on. If so, which and
all modules responsible for displaying the charging icon?
It will be very helpful if I get any document/information in this regard.
Thanks in advance,
Raghavendra

depends
if the 'charging icon' is the charging LED, and by off you mean you have
selected the 'Power off' menu item, from the list on the power button.
then the phone is off, and the hardware is showing the LED.
if you power the phone off and there is something showing on the screen,
then likly it is the 'bootloader' which is like a 'bios'. This all
depends how the hardware is done by the ODM.
