I bought 2 extended batteries when they were first released and I switch them out on the first of every month. It cost me a little extra but I can go a whole day and then some with a full charge at the beginning of the day, and both batteries are still going strong.
However, I'm still waiting for additional info on Verizon next big phone, the Maxx HD. (if I live long enough) Haha!
The government can't give you anything until it first takes it from someone else!
