It certainly wouldn't hurt anything to have both the battery and the device tested. With optimum settings and a fair amount of usage, I am getting a few hours more than you are and would say most of the guys around here would agree.

Your area is very much a concern to your battery life. How is your roaming setting (In Settings->Phone->services tab). If its Automatic and you live in an area with good coverage, try changing it to Sprint Only. I got a lot better life out of my battery when I did that.

Also, make sure bluetooth is off. With bluetooth on for me, I bet I couldn't even make 8 hours, even w/standby!

At least the corp Sprint Service & Repair store can test your battery and test your antenna on your phone (It is common for a device getting very poor batt life to have a bad internal antenna - IE the phone isn't getting a good signal which causes the batt to work much harder. Very easy 3 minute isolation box test to rule this out that can be done at your sprint store)
