Review: HTC Droid DNA for Verizon Wireless

Agreed there are portable charging devices that can be carried around to charge the built in non-removeable battery, but the smallest of them is not that small, and its annoying to have to equip your pockets with more lameware than your device and its carrying case.

For most people, that dead battery in a phone like the DNA must to be charged a few feet from that A/C outlet. This is confining and a limitation. The spare battery of a removable can be charged while your frollicking about. The two situations do not co-exist in attraction, plain and simple...It is more convenient to throw in a fresh battery in an instant than to deal with that wall outlet!
