First, I turn my phone off before takeoff. This saves a lot of battery.

Man, you guys are really planning for a camp out. Now likely as not, when I=

iPhone 5 will also last at least three days on a single charge unless I am =
gabbing on the phone a LOT. How many 3 or 4 day retrieves have there been,=
recently?

I have been in places where the cell phone goes through the battery much faster
as it tries to maintain contact with a cell system. On one trip through northern
California / southern Oregon, it went from fairly close to full to shutting down
dead overnight. The same thing might happen in flight, depending on terrain and
distance to a cell system.

It doesn't take 3 or 4 days to flat a cellphone battery in some out of the way
places. Dan and Ramy have good suggestions.
