iPhone battery life: I'm flying across the Pacific tomorrow with a 2 year old and a 5 year old. They are iPhone fiends (god help them), but I need to know if there is a huge difference in battery consumption between the education apps they usually play ("Find the sheep"..."Baaaa") and videos. I suspect that videos will use up battery life longer than these really simple apps, but I'm not sure. Anyone know?

Sometimes, my iPhone 3G usage statistics are totally out of line with my actual usage and the battery is drained accordingly. This doesn't seem like a settings issue but rather some application or service getting "stuck" and not turning off when the phone is locked. Any ideas what I can do to address this? [more inside]

How long does your iphone (3G) battery last? [more inside]

We've all been reading about the iPhone and its battery that's supposed to last 300-400 charges. How do they define "charge"? I usually charge mine every night, when the battery is at about 50%. Is that a "charge"? If I top my iPhone off when it's at 80%, is that a charge? What's the best way to preserve the life of my iPhone battery?
