...my battery lasted all the way through the day, in fact it was at 38% when I put it on the charger last night after 12 hours of use. Perhaps some of the reports were correct about giving it a week because there was an undeniable difference in the life of the phone today. I can't provide empirical evidence as to exact usage on days 1-5 but it was extremely similar on each. Haven't set the thing down since I bought it. Still looking forward to an extended battery but it's nice to make it through the day finally.
