Hi,

I was wondering why my n900 drains almost empty in 8-9 hours. Even during night time it consumed almost half of the battery.

My colleagues had about same settings (weather widget, 3G connection on, email checking, RSS, BT) with similar use and their devices lasted well over a day.

The only difference was that I have skype and the availability setting was "online" (green dot in status display). I changed that to offline and now the battery is almost full after night and seems to last very well the rest of the day and even the next night.

Does anyone know what is happening under the hood?. Top does not show any significant change in CPU load, but something must be eating the battery in online mode
