Batteries do go bad, but not that often. Batteries though do take a bit of conditioning to maintain their health. In addition, if you are in a signal inhibited area, battery life will suffer. Have you noticed what the signal strength is showing and if 3g is routinely showing? No 3g also equals bad battery life. Look here before starting to play with a task manager. I get 6 hours maximum time of use with my Evo due to how I use it and it charges all night long.

As a side note, punctuation/syntax makes reading easier.
