My first smartphone was a Motorola Droid. It was painfully slow and had horrendous battery life. Each successive phone I've owned since has steadily improved both usability and battery life. My current phone has twice the battery capacity of my original Droid but lasts much more than twice as long. A decade of efficiency improvements in both hardware and software has made a huge difference.
