I remember my first Android phone, the Samsung Moment, had a single core 800 mhz processor, 500 megs ram, and a 3.2 inch screen and lasted a day. The fact that now the standard is quad core, quadruple the ram, more radios, 5+" full hd screen and still last a day is pretty awesome. These phones pack more power than supercomputers did back when I was a school boy. Can you imagine running a supercomputer cluster a decade ago off a battery the size of a playing card? I understand that our battery technology needs to advance, but I rather have only a day of power and a greatly capable device than a week of power on a 1.5" flip phone. Besides, I sleep almost every night, I have down times at work that I can plug in and I am in my car more than a few times a day so if i need power, it's pretty likely I can get some. I am sure that is true of most people. My Evo 3d is barely able to keep a charge for more than 4-5 hours of standby and maybe 2 hours of light use after 2 years, but I am still able to make that work for now until I get a new phone later with tri band support. You just have to know how to balance playtime/work time on your phone with reasonable understanding of your battery life.
