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!
