A comment on Airplane Mode.

Very respectful, and awesome closing off of the world temporarily.

Another 'use' I find - in areas where you know you'll have no signal. With the cell radios screaming to contact a station, drains the battery worse than more or less any other part (unless you have the display on 100% brightness as well as on all the time)

Nice to see this hypothesis observed by others. I long suspected that "failing to handshake with a cell tower" incurred a significant drain on the battery.
