Iphone 4s battery dying fast?

I just got my iphone 4s 2 days ago after upgrading from the 4 and i don't know what the problem is but the battery dies way to fast. I just had to turn it off to save some power until i got off from work. I turned Wi-Fi off, turn the brightness on low and off auto, etc. If anyone else has any suggestions on what i should turn off or do ill take it. My windows phone was like this and i immediately took it back.i've been dealing with the iphone since the very first one that came out and never had this problem.

Make sure you close down the apps your not using and make sure you have your email setting to push setting on manual. That will save your battery life.

Its normal.
the 4s has the worst battery life of any iphone.

When you get a new phone, the battery much complete several cycles before it reaches full capacity. Allow the battery to drain entire, then charge it back up, several times, maybe up to 10 or more, before the battery will be at full capacity. The charge life should last longer each time. It is also very important to charge it up all the way on first use, this will give the battery more capacity.
