My phone battery last all day on a plane. That is because I turn the
phone off since calls are not allowed....

On a plane I listen to my iPod and sometime watch a movie on the iPod.
Never even came close to running out of battery power. Longest flight
was 5 hours. If I had an iPhone it would be in airplane mode and I
would guess it would have similar battery life to the iPod.

On trains where calls are allowed I often run down the battery on my
cell phone. But I don't carry a spare battery. I plug my charger into
the outlet Amtrak kindly provides. I would do the same with an iPhone.
