Battery Low!

Address book access...

It was a cold winter evening. I was stuck in the bus terminal with my baggage, cell phone and a few extra quarters. This story is set during those days when people did not know other peoples telephone numbers; just their names in their cell phone address book. My battery is dead and so I cannot use the pay phone even though I have the change because I can’t for the life of me recall any number. And that’s when it struck me. What if my cell phone had a feature where there was a reserve battery life which was restricted primarily to access the cell phone address book? It would not allow me to make a call, or for people to call me (ringer plus talking are power hoggers) but on the other hand if in case someone did call me it would flash his/her name and number and let me access my address book (which I hope uses seller batter life than talking). The good thing is that it’s after 9:00 PM so even if I don’t have the change I can scroll my address book...note a number… Walk up to a friendly stranger and ask if I can use his phone and call my friend to pick me up.

       i think its a good idea, but sooner or later all power to your mobile/cellular phone will die and you'll not even have access to the address book. I have an idea to fix this .... see link.

       haven't u already put up a post for an auxillary battery before?

       nomadic_wonderer: what you really need is the windup charger -- see link

       [theircompetitor] or maybe all I need is this feature without the addition of any cumbersome addition

       Build your cell phone into one of the lovely devices in the link. Replace spring with generator and charge as you exercise. -- "Must be a heavy talker, just look at those hands."   

       For the frustrated office worker a stress relief rubber ball could be used instead, but that may require some Piezo-electric magic.

       good idea except one point   

       most of the power is used by the cell phone signialing to the cell phone tower   

       you should make it start up with not "cell" features at all just the lcd and the phone book   

       that couldnt reqire much energy at all

       Why don't you just re-route auxiliary power though the secondary phase transducer of a phaser or tricorder?
