Assuming you could transfer all of a battery's charge capacity in seconds, the notion that "energy = power x time" still applies. You may have already seen how hot AA batteries get in the 15-minute chargers. I wouldn't be eager to throw a phone in my pocket after that. You would also completely do away with the convenience of being able to charge the phone via USB and be back to every device having separate, bulky charging adaptors.

Seems like it would be easier to carry a spare USB cable and charge the phone more often or buy a second battery on the Internet.
