useful for someone.
Unfortunately, concistent numbers are quite hard: longer/thinner
cables mean lower voltage and also lower currents :-(. I get quite
consistents 5V at power supply, but it goes down to 4.5..4.2V when it
reaches zaurus behind ampermeter. (Is zaurus even able to charge
battery properly from such low voltage?)
One big surprise was wlan CF card, eating +200mA when initialized.
I'm working on drivers/power/spitz_battery driver, and I'll need to
know conversion between ADC readings and milivolts; does someone have
Does someone have better/more reliable/other power consumption numbers?
