Battery indicator when charging?

[influenza]

Hi,

I've got an European a780 (dutch) and I have the following strange thing: I charge my A780 completely using a normal power outlet. Agfter charging the battery is at 100%. If I for example conenct my phone to my pc with the usb cable. Both my phone and MPT show a 20% battery capacity and start charging. This is also the fact when I use the car charger. So for some reason the battery indicator isn't correct?

ok, it shows 20% and starts charging but in a minute phone discovers that battery is already charged and shows 100%.

Indeed. When the phone is charging, it's as if the charge indicator reflects the progress made since it started charging rather than the absolute charge level of the battery.
