GPF5 is linked to in/out port WLAN_GPIO1 of same CON7901 (aparently related
to wlan wakeup)
Here GPF5 is high (1) when the wifi is disabled and goes down

Remove SD card and SIM card and see?

I also did this using qtmoko (setting deep sleep mode in

Deep sleep only matters if the GSM chip is on.
Should I conclude to a hardware bug ?
Any idea where/how I should look for ?
My expertise
So I checked charge_now during suspend (measuring before and after
suspend of course) and it seams that the battery is then discharging
at the rate of 23mA, which leads to a total of approx 50 hours.
That looks indeed like either mis-measurement or software
mis-configuration, e.g. you

Ruling out mis-measurment for now, apart from GPS abnd bluetooth do you
know of some chip that could draw so much current ?
How much does it consume if you turn GSM off?
Should be ~3 mA.

What's the surest way to turn it of, bypassing the distribution ?
I use om gsm power 0 with omhacks in debian. It uses /sys files that
depend on the kernel version you have, I do not remember them by
heart unfortunately since I use the shorter command.

Your figure is good. #1024 fix saves you about 4-8mA, a considerable
amount during suspend-to-ram, but you won't notice the difference if
you keep the device in idle but not suspended state.
Ok, make

I thought the #1024 fix is only helping while the freerunner is
suspended. For me this fix only changed the current which was consumed
while suspended and extended my standby time by a factor of nearly 2x.

Ok, make sense.
So I checked charge_now
I monitored power consumption all day long (from full battery to empty).
I observed that the average current consumption (from /sys/.../current_now)
is 78mA when idle. My battery, at full charge, is shown to store 1.1Ah
(according to /sys/.../charge_now), which leads to battery life of 14h which
