Lithium ion batteries also can't reach a zero charge without causing permanent damage to the battery, so the electronics built into them will shut them down before they reach an absolute zero charge. I'd assume the meter would take this into account though. Have you tried recalibrating the battery? I haven't done this on my iPhone, but I did it recently on my netbook, which was automatically shutting down when the battery indicator was still saying I had about 30% charge left. After recalibrating, it's acting normally, although I haven't actually seen how far I can take the battery charge down before it shuts off, it is letting me know I have significant less charge in this old battery now than it did before I recalibrate. To recalibrate, just let the battery go down as far as it can and then plug it in and let it charge all the way up. I've seen people say you nay need to do this 2 or 3 times, but I've never done it more than once myself.
