I think that's why you get so high currents. This
# echo >/sys/class/backlight/gta02-bl/brightness 0

You must have done something wrong. I frequently test power comsumption
and I get 54 mA on
Because display and GPS chip may be powered on for a long while, I

Phone is GTA02v5. Distribution is latest SHR unstable, with almost 0% CPU load.
No devices(WIFI, GSM, etc) opened before this test. Battery capacity
is about 88%.
My test method is, for example: set displ
