Well it doesn't mater how much it is real (=accurate) but whether there
is such circuit which simply stops charging and cuts also the input from
battery to not discharge it when you have AC adapter. This is IMHO done
in all modern laptops with li-pol batteries to extend life of battery.
Otherwice regular charging and discharging near the 100% and 99% level
would kill the battery in really short period. There is no such circuit
in n770?
Even if it were, it wouldn't make much sense to measure at the mains
plug if you can do at the battery.
...
To put things straight: If you measure "charger plus 770", you measure
exactly that, nothing else. All assumptions you draw from it about
the Nokia's power consumption alone are worthless without knowing the
charger's part.
Well I was not thinking about measuring at the mains plug. I was
thinking about measuring at the n770 side (5V?) because it is a bit
easier then opening the device and messing with battery pins.
