I guess you're talking specifically about smart phones, because my
ClearNav II is (subjectively) many times brighter than my Dell Streak 5
which itself is brighter than any smart phone I've seen to date.Â*
Admittedly I have neither seen them all nor tested any objectively.

That said, why worry about battery life when it's so simple to take a
USB panel mount cable, cut off the computer end, and make it into a
power jack for your phone (red and black wires connected to your DC
bus)?Â* Or simply purchase a portable 5v lithium battery

which will fit easily in the side pocket.
