Mobile Battery

So what's the problem?

Is this something with castors underneath it to enable it to move over smooth surfaces?

How much energy can you pack into a few cubic centimeters? Would you want something approaching the makings of a bomb close to your ear anyway?

not the battery is the problem but the power requirement for the mobile. If there is lower power used the use time could be longer. Any way the batteries did progress a lot not so many years years ago you could not find so high energy densities as today

For the exact same reason we live only 60 to 80 years (Average). At the end of this time our batteries are flat, gone, kaput.

Wangito.

If a 2-3 day battery life is inconvenient, try the old fashion land line. Long phone cords are available and quite reasonably priced. If you want longer battery life simply turn your mobile off. My battery doesn't sometimes doesn't make it past a day. Be grateful that they are not powered by fossil fuels. Solar panels would also be an option. Please send some photos. I could use more examples in my "redneck invention" colection.

It is the advancment of Tech [Electronics & component] & Materials combined that the AH capacity of batteries has increased atleast 20 timesfrom the batteries of 1950s or even 1960s. You may remeber the Torch cell Type 'D' Cabon-Zinc have max 1/2 AH while the same type Ni-Cd has >4AH. Battery used in Mobile is the latest Li-Ion having much more than Ni-Cd not in capacty but also charging cycles.

Alot depends on how much the telephone is used. A telephone in the pocket uses much less power than a telephone in the ear... and a telephone on "OFF" uses virtually no power at all.
