I do not doubt this has already been implemented, so I'm not
suggesting it is novel.
Why don't analogue battery level indicators show full until the
battery discharges to a certain point? Then they could (maybe) change
colors and then begin decreasing from full.
In other words...
.... start with a battery level indicator bar
.... have that bar remain the same color and appearance until the
battery level drops to 50% or whatever
.... at that point, change the color to red/whatever, and begin
indicating further discharge by decreasing the length of the bar
The problem is real estate and LED electricity usage. That way you can
use a shorter bar and change the bar's appearance only when the
battery level is important. Most people can remember that they have
recently charged the device. Before taking the device on a long trip
or whatever, it should be left in the charger anyway. In other words,
knowing that the device is full or nearly full is mostly useless, so
there is no need to waste the space and energy by indicating that. The
user mainly needs to know when to start looking for a charger.
Too many devices do not give enough warning before the battery needs
to be charged.
