On the one hand, I generally favor allowing users/their apps to get more granular information out of their phone rather than somewhat arbitrarily deciding what they need to know (e.g. there's more GPS detail that iOS could provide but doesn't).

However, in this case, the phone has a battery meter and provides its own low battery warnings. I imagine you could have more sophisticated battery use tracking apps than Apple provides but, in general, not sure why you would legitimately need this info.
