What exactly is your concern? * That the power display includes a time remaining? * That the time remaining is wrong? * That the time remaining is right, but should be longer? * That an earlier software release lasted longer on battery? * or some combination of the above? I'm poking around to figure out where Sugar gets that number for the time remaining. Aha, it's in this code: /usr/share/sugar/shell/view/devices/battery.py #TODO: make this less of an wild/educated guess minutes_remaining = int(current_level / 0.59) remaining_hourpart = minutes_remaining / 60 remaining_minpart = minutes_remaining % 60 secondary_text = _('%(hour)d:%(min).2d remaining' % { 'hour': remaining_hourpart, 'min': remaining_minpart}) How, uh, unusual to slip this into a release at the last minute! The battery code has moved all around in the last two weeks (I think it's been in three different places in the Sugar tree), so I found it too hard to track who put this change in, and why. I recall some free code that tracks battery performance over time, and produces increasingly accurate predictions of when your battery will run out, after watching your particular battery and your particular system for a few full power cycles. But a bit of searching didn't turn it up for me today. John _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
