Decrease your display brightness manually and turn off extra features. Pretty simple really, if kept on auto the phone will adjust the screen brightness according to the ambient light conditions. Features like Bluetooth, AirView and GPS can really eat up your battery’s charge. Simplify. Use a simple wall paper, something that is colourful and animated will drain your power. Also, try and have as few home screen widgets as possible since they are a major source of battery drainage. Finally, use power saving mode! It has been specially designed to help save battery life and it actually works.
