Query: battery lasts 8-10 hours

I am now going to be on my 4th phone today because the first defective ones touchpad didnt work and the next two phones wont hold a charge more than 8-10 hours. the up side is the camera works nice. my e-815 was over two years old and working fine until verizon kept calling me every day bouuing me to upgrade(what a mistake).make sure if you decide to go this route that there arent long lines at your local store because you will be going back many times.
