i don't thing getting a new battery is gonna solve your problem. 14% loss in 1hr 33min is not average. Things to take in account...
#How many widgets if any do you use, when or how often do they sync?
#How many email accounts are you using, when and how often do they sync?
#Are you using WiFi? No Wifi more battery drain.
#Are you using 4G or just 3G. 4G sucks battery dry, and if your in a bad 4G area and consistently bouncing between 4G/3G your gonna kill your battery.
#Do you use apps that consistently check your location or update your location?
#Bluetooth always on?
#Their are alot of things that can run in the back ground even when the phone is in sleep? Is your phone even going into deep sleep (CPU Spy) you may have a rouge app not letting your phone go into deep sleep.
#How many things do you save or sync with cloud services?
#How Much screen on time are you using. Auto brightness is great but if your looking at your screen for 3hrs a day your still gonna use alot of battery. Screen on-time is what you really need to pay attention to.
Im sure there is a lot more but you get the gist.
