i don't think there is going to be a single solution. * the early usb portable hard disks i got often had a triple ended usb cable; one end for hard disk, one end for data connection and an extra end to draw extra power for the hard disk. could this be done for charging phones? * offline maps would reduce the power required for navigation as sucking down data on 3g is power intensive. you can always turn off 3g and use slower 2g for lower power consumtion. perhaps even an option that if they are using voice to turn off the screen completely. * somehow convince the manufacturers that many don't want a superslim phone. if it's twice as thick with twice or more the battery life then i am really interested! even if it's only as an extra option then a certain amount of people will pay. * removable batteries. designing for removable batteries makes models bigger and bulkier but they are more useful when you can get and carry spare batteries. * some form of standard batteries that persisted between makes and models so that people could invest in extra batteries and know that they will work with the next generation? in 94 i could get a week from a psion pda with 2 aa batteries with no effort getting 40 hours of use. in 04 i could get 2-3 days from a symbian device pushing it to it's limits. in 09 i could drain an iphone 3g to zero in about 2 hours. it just seems we are going in the wrong direction.
