It can be due to many reasons. Firstly, there can be many heavy ram consuming apps running in background. Try to close them. Keep the brightness of screen low. Keep Wifi and Other data connections off when not needed. You can also turn off auto-rotation. This will increase your battery backup to a considerable amount.
Incase, it doesn't makes much of a difference, you should buy a new battery !
