My HP G62-121EE laptop has libupower-glib1 and upower installed but it shows just "laptop battery (estimating)..." :-( But if I click the menu, the power statistics shows correct values for the Energy, charge, battery capacity, etc. Probably the developers could introduce a daemon which monitors the battery charge during discharge, compare the value with battery capacity, and compute the estimated time remaining from the 2nd minute, every minute :-) This would be a machine/driver independent code and also be intelligent enough to show correct statistics, even if the user changes his power-management schemes. An important note, though, is to have a timer ticking (restart the timer after *suspend*-resume/ *sleep-*resume/ power-on) for the daemon itself, instead of using system clock. This is necessary, else the computation would be wrong if a user resumes the session after a sleep or hibernate. Worse still, it would be inaccurate if the user has changed the battery after a hibernate!
