i use my device constantly...and no games either.

stuill have to change a battery every 2-4 hours, so i carry 3-4 extra batteries in my pocket and have 1 extra n900 just to help charge my batteries.

if this works and can cut it down to 2-3 batteries per day....that will be great!

im testing now. yesterday was little use, and on days like that, i usually only change the battery every 6 hours. yesterday i got 9.5 hours out of one battery.
