Cell Phone Feature: Power Reserve Mode

It's great that cell phones can do so many things, but for most of us, emergency/short-notice communications device is by far the most important one. It's nice to play MP3's from my phone, but I don't want to run the battery to nothing doing that, and have it fail me at a crucial moment. So I would like to have a "reserve mode" feature, in which a cell phone pauses non-critical features, to warn you that battery life has dropped below 20%.

Noted that this may be the kind of feature that sounds good on paper, but adds more complexity to the platform than the feature is worth, if it causes flaky or unreliable behavior (like Windows Power Management has been known to).
