That is pretty good battery life!  WiFi is a killer.   
 I charge my battery every night before I go to bed so I never have a dead phone.  I use my phone a lot, texting with audio alerts on, gtalk, gmail, browsing the web in a very low signal area, my screen is on max brightness, and bluetooth streaming pandora in my car.  4G LTE is always enabled with the exception of work because I only get 3G in the building.  When I go to bed at night battery is at 50%.  Couldn't ask for better life from an android device.
