Why Is my iphone battery bad on ios7?

So after ios 7, my battery has been horrible. I have turned off background refreshing, reduced motion and my brightness is very low. Where I go to school though, my service is terrible. I'm constantly searching. Could that be the reason? Or do I need to reset my phone? Note- I get about 4 hours of usage per charge.

Turn off background updates? Basically anything you run automatically hurts battery on phones.
