I went to Disney's Magic Kingdom not long back, and my iPhone lost its charge in record time. My battery was drained before lunch, and I had no way to take photos or videos. I want to make sure this doesn't happen again tomorrow when I go to the Animal Kingdom. I want to shut down anything that pings out or wants to use my battery. I'm going to want to use my video function on my phone, and I don't know how much juice it sucks up, but I'm going to need all I can get. I wish there was one check box or something that would disable all unnecessary functions for situations like this.
