Battery life estimation considered impossible?

In the course of updating sugar/view/devices/battery.py to look like
Eben's new design, I wasn't able to come up with a satisfactory way
to calculate remaining battery life.
Can anyone opine as to whether it's possible/feasible right now to
estimate number of minutes of battery power remaining?
Can anyone do better than my naive algorithm?
3. minutes_left = battery_capacity_pct / 0.59. From . The magic
constant is about 1.2 pct of battery capacity = 2 minutes of power;
this is what I've observed and consistent with other reported
capacities I've seen; but of course the approach is fatally flawed.
