Title:
Icon colour changes at inappropriate times (too early; red, yellow,
green)
Status in Gnome Powermanager:
Fix Released
Status in “gnome-power-manager” package in Ubuntu:
Triaged
Bug description:
I have an IBM X40 with an extended 8-cell battery. The total battery
life is between 5 and 6 hours. I run Edgy.
GPM changes the colour of the systray icon from green to yellow when I
hit 49% remaining - i.e., using today as an example, when I have 2
hours and 31 minutes of battery life left. This is more than most
laptops have at 100% charge. It changes the icon from yellow to red
when I have about an hour of battery life remaining. This is also
unnecessarily scare-inducing.
This is clearly ridiculous. The colour should be based on the time
remaining, not on the percentage remaining. I suggest:
> 45 minutes: green
45 - 15 minutes: yellow
< 15 minutes: red
This may, of course, require the icons to be dynamically generated or
coloured, rather than using a fixed icon set where colour is
inextricably linked to the "fullness" of the battery. But it would
make the indicator a heck of a lot more useful.
Another alternative would be to have an icon mode (either the default,
or an option) where the percentage left was overlaid on the icon
itself. Then I could ignore the colours and read the real situation.
Additionally, if you imagine the "fullness" of the icon as a series of
rows of pixels, then a particular row of pixels gets "un-coloured" as
soon as that row is reached, rather than half way through the range of
percentages it represents. In other words, when I go to 49.99%, the
indicator shows one row of pixels less than half full. This is a more
minor point, but still irritating.
These two factors together lead the icon to imply that I have less
percentage battery, and less actual battery time remaining than I
have. The result is that every time I want a sensible estimate, I have
to mouse over the icon and read the tooltip - defeating the point of
having an icon.
One last thing while I'm here: it took me weeks to work out that the
"AC charging" version of the icon had an overlaid electrical plug. I
really couldn't work out what it was. Take a tip from the mobile phone
industry and overlay a lightning bolt in the centre of the battery.
That's a fairly standard convention now.
