Odd iPhone Battery incident
Today while I was on my walk, the battery on my iPhone 5 ran out abruptly. When I left for the walk, I had 40% battery left. I was listening to music, which usually doesn't eat up a lot of battery. Anyways, at a point during my walk, about 45 minutes into it I had to turn my torch light on because I was on an unlit path. About 10 seconds later the phone turns itself off, claiming it was out of battery. When I get home and plug it in, the battery indicator reads 34%, which would be believable for the amount of time I was listening to music. The question is, if it had a third of the battery left, why couldn't I turn it back on again?
