Some people are Power users (pun intended) other are not with the X, have you gone out and got a secondary charger or just the micro usb cable for hook up to your pc or wind up cell charger. Im think about carrying a usb cable in my backpack so I can charge it mid-day and make it home with a charged battery. Lately Ive been using Juice defender and most of the time I get home from 7:30am - 7:00pm with about 50% left on my battery with moderate to heavy usage.
