Comment 29 for bug 120258

I think the problem is that gnome-power-manager takes the value from the battery. For example LiOn batteries tend to report lower times if they were stressed by higher energy consumption for a short time. I think we will get more accurate values if gnome-power-manager calculates the remaining time from the remaining energy and the current consumption (or weighted average of consumption values for 5, 10, 15 minutes while lastest value has the highest weight).
