Battery dying very fast iPhone 4s

I love my Iphone 4s, but my battery dies so fast... I used to have and Lg vortex very simple, and my battery would last 2 days at least...

So I have been trying to turn off some stuff:

Go to SETTINGS;

(if you are not going to use it of course).

*turn off Wifi.

*Location Services, (you can Always turn it on Anytime, I use a lot the GPS)

*Bluetooth Off

* In Brightness I use it in Low.

Little things like that could help your battery.

Also to not have lots of apps running:

Push twice the home buttom.

Then a menu will pop below.

Select and Keep Press the apps, And you will see ➖

Press it, and you will stop from running the App.

I hope it helps you...
