with Ni-Mh you can count charge cycles charged but not with Li-Ion. They can be topped off with no penalty in charges, unlike previous technology. The best way to count the life is to count how many full charges from empty they have had where topping off counts as a partial charge and you add together all of the partial charges and the % charge they accomplished to figure out the equivalent of a full charge. Even then it is only an estimate. And you wonder why there is no app for that.

The best policy is just to do what they do and measure the time to depletion. Typically that is about 1.5 to 2 years for most folks to hit a point where they begin to really notice the drop off in time. It is not linear though as it tends to taper off toward the end.
