Sadly, my phone died last night making pictures. One of them should be shown above. Anyway, in the morning, which is right now, I kept on pressing the top on/off button (I have an iPhone 4, by the way) and guess what showed up? The Apple sign, meaning my phone was powering up. It gave me 10% left on my phone! So if you want to try this, go ahead. It may or may not work. But try it anyway!
