I can absolutely believe this. It just depends largely on what the screen is displaying and what you're doing with the phone - sucking down netflix for example is likely to eat battery more quickly than email, calendars, and texting.
I have been nothing but impressed with the battery life on my Note 3 - I generally unplug at 7:30 AM and am still in the 30-40 range around 11:30 when I'm about ready to plug back in - some days more, some less. It really depends on what I'm doing on a given day.
Also a factor - repeated signal switching. If you're phone is constantly searching for an LTE connection and/or switching into and out of one, that can chew up your battery.
So the OP needs to evaluate his/her activities and see if the battery usage seems high or not. It could be a bad battery, or it could be related to usage profile.
