One would think, of course, that since any particular company has control over and thus knows the discharge profile of the battery in the device, it would be fairly simple to take snapshots of the battery's voltage every few minutes or so (or with an e-ink device, every time a button is pressed), and just compare that to the battery's known voltage drop-off graph for the battery type to get a fairly accurate picture of where the battery charge is on that profile. That way the meter could display a charge level to the user in a more accurate, linear fashion that would make more sense to the average person instead of getting what HarryT described.
