Can I please have some ideas about why my iPhone battery is draining so quickly? I close my apps when I'm finished using them, I turn off my Bluetooth and wifi when not using them. I don't know what else i can try.
According to apples website I should get 8 hours of talk time, 3G, and lte use. I never even get this on stand by.

I wouldn't necessarily take Apple's word on how much of use you can get out of your iPhone given it's mostly marketing and reproduced in specific lab conditions. Here are some real world numbers from AnandTech's iPhone 5 review. The differences can be quite significant for instance, 4.55 hours on 3G and 8.19 on LTE.
Note that this is presumably for a brand new iPhone 5; if you have one that is more than a year old, it would probably be around 80-90% of it's maximum battery capacity.

From my own experience, I've noticed that apps that utilise background app refresh in concert with location services tend to be pretty expensive in terms of battery usage. Dropbox and Downcast use these to upload photos and download podcasts in the background respectively - location services appear to be turned on all the time when these Dropbox/Downcast features are turned on. I turned off background app refresh and location services for both of these apps and have noticed quite significant improved battery life.
