One of the major bottlenecks in the development of todays mobile phones, is the limitation of power technologies.

To have a conveniently portable handsets, the battery pack has to be rather small. But current Li-Ion batteries just can’t pack enough power to satisfy the power needs of all the chips, that fit into the latest smartphone.

Now Samsung has a neat idea, described in recent patent application, of how to remedy the problem at least a little bit.

Use the front surface for a bigger display and some navigation buttons. Then make a battery pack into removable keypad, move the keypad to the backside of the device and add small screen for calling functions.

And it’s a win all around. You have a space for a bigger display, a place for a bigger, keypad sized battery. And you also can have a multiple keypad battery packs with different layouts.

Don’t like the traditional 3×4 key layout? Just slap another keypad battery pack onto a phone, with smaller 5×4 keys, and you are done.
