first battery life depends on usage, signal , screen brightness, etc
i have one day or two of battery with aprox. 3.5 to 4 h screen time on.
if you use Bluetooth, gps, take a lot of pictures, use the screen reading and writing you will have a few hours of juice.
too if you have a lot of social applications that connect a lot to internet or make a lot of calls.
to test disable all radios ( WiFi, Bluetooth, GPS, DATA, NFC) too disable synchronization and try for couple hours.
view the results... I usually disable all on night and have 5 percent of drain in 6 or 7 hours.
you can do a master reset and test for couples days, with no app installation or less possible, and see.
