So, what the spec says is:
> * The charge level should be visually supported through the different states
> of the battery indicator icon (i.e. 20%, 40%, 60%, 80%,100% & battery
> charged) in the status bar.
> * When the phone drops below 20% power, the battery indicator should turn red
> giving a nudge to recharge.
I-power currently picks the closest match of the -000, -020, -040, -060,
-080, and -100 icons; e.g. a charge of 51% will get the -060 icon, and a
charge of 49% will get the -040 icon. This is /usually/ The Right Thing
because it minimizes the difference between the icon level and the
actual battery level.
However this does mean 29% shows red. So we need a special case to treat
the 20-30% range as a special case that deviates from the "closest
match" approach, such as:
[0%..10%) battery-000
[10%..20%) battery-020
[20%...50%) battery-040
[50%..70%) battery-060
[70%..90%) battery-080
[90%..100%] battery-100
This works but isn't a great fix because the icon-to-label shear can be
up to 20%: if the battery is at 20%, the label will read 20% and the
icon will show 40%.
We also can't just change the 20% icon to black because we also want to
maintain compatibility with other in-house and third-party icon themes
on Desktop.
IMO we should do the closest match / special case approach listed above
but ALSO add new charging/discharging icons for battery-010, -030, -050,
-070, and -090. i-power would generally match to the nearest 10% icon,
add a special case for [20-25%], and use the existing GNOME icon names
as fallbacks.fallbacks.
This approach would:
(a) Fix this bug
(b) Not regress on icon-to-label shear. (Currently the max is 10%, under
this scheme the worst case would be a battery at 20% and an icon at
-030) and in the general case it would /reduce/ the shear since we'd be
matching to the closest 10% instead of closest 20%.
(c) Maintain compatibility with other desktop icon themes by using the
current names as fallbacks

Battery icon turns red at 30%

Bug description:
This seems a bit pessimistic since the phone still has a great deal of
capacity and time left, perhaps 15 or 20% is a better threshold
