Bug Description
Please take a look at the attachment.
The percentage charge remaining on my battery appears to show my battery emptying fairly predictably (graph #1). However, the very important Time to Empty statistic fluctuates quite a lot (graph #2). Certainly more than the charge remaining graph suggests it should. I believe this is because of the rate of power consumption (graph #3).
I believe that the Time to Empty statistic should be refined to take into account a longer period of time previously. Clearly the statistic needs to change if more power demanding activities are being carried out. However, it shouldn't change so rapidly - brief fluctuates should effectively be ignored.
The Time to Empty number is incredibly important to users' use of portable devices.
Note: this may be something that needs addressing in one of gnome-power-
