On my original iPhone, a full battery provides enough call time, but any amount of internet usage quickly drains it. Whether I am trying to do email, web surfing or watching YouTube, within 10 minutes or so, the iPhone will crash, and when I turn it back on, the battery says it's at 10%. What's confusing about this is that at the moment before it crashes, the battery indicator has been up to 100%. I know that internet usage drains the battery faster than phone calls, but seriously?
