I have an iPhone 5 and noticed the following. My battery is showing 30% or more; I start taking photos (with flash) and all of a sudden (within minutes) the phone turns off as if it was completely discharged. I plut it in, and within 5 minutes the battery is showing 40%.  The fast charge time and the very unexpected turn-off make me think the battery wasn't really at 0. Am I wrong - could a few flash photos drain a 30% battery to 0, and could an empty battery charge up to 40% in a few minutes (being plugged into a car charger)? Or does my battery need to be recalibrated somehow?
