Comment(by gena2x):
I did measurements with multimeter, and found following.
First, i measured qtmoko on nand:
fully loaded qtmoko = 220mA
qtmoko sleeps without deepsleep enabled = 32mA
qtmoko sleeps with deepsleep enabled = 9-18mA
on om-gta02-34, the power consumption with loaded X is 250mA
on om-gta02-34, in suspend, it is 100mA
some additional info: both u-boots draw 350mA while in menu -> strange.
additionally i found that i can't do GSM calls in multimeter configuration
in qtmoko.
additionally i found that if i disconnect usb power supply, i can't
register to gsm network in multimeter configuration (and can with adding
usb power supply), both reliable.
