>This should be accounted for in the initial design, so that there is sufficient battery life at the end of product life, not just at the beginning.

If this was the case, the title of this post would be "iPhones don't use all available battery power" instead of what it is. You can't please all the people all the time.

I'm really not sure how that follows at all. If the battery life of a new device is 3 days, and the battery life of a 2-year-old device is 1 day, at no point is there battery power that is unused.

People would be so upset that they didn't have to charge their phone so often and that the completely sealed in battery lasted longer before making their phone appear to become obsolete?

They might be upset when their phone was 3/4 inch / 2 cm thick and weighed 3/4 of a pound / 1/3 kg.
