Compared to my RAZR this thing is amazing. I have already rooted my phone and took off all the Verizon junk. My battery lasts most of my work day which is impressive since I am constantly on it for calls, text, emails (personal and work), using my scheduler, S notes, and checking my stocks. I usually have 40% or so left by end of my day. I dont know if that helps at all, but you could always root and get rid of the things you don't need or put a new ROM on.
