Use solid black static wallpaper
Samsung Galaxy S2 Super AMOLED Plus uses less power on solid black wallpaper because (almost) no backlight is output. And try not to use beautiful live wallpaper. Why? Lovely animation costs you ~ CPU power == battery life.

Fully close application that not use
SGS2 is a great multitasking machine. But by letting lot of applications running at background actually increase battery usage because they still require CPU processing. So fully close those applications that not needed.

Undervolt and underclock CPU
Besides display, SGS2 CPU is the second biggest battery life eater. If you don’t need 1.2GHz processing power, underclock and undervolt it with SetCPU for Root Users.

You can freeze Samsung bundle software like Social Hub, Email, Maps if you don’t need them with Bloat Freezer or Titanium Backup Pro. Why? They are running as service even you are not using them at all.
