IPhone 4s battery help?

[Nicola]

Ok. So I have the iPhone 4s. I'm a very businessman who needs to use the 4s quite a bit throughout the day. The problem is the battery sucks! It can not last me a whole day. I have researched and so far I have limited push notifications to messages phone and Facebook. I always have off location services unless I need it on maps. My wifi is sometimes turned off when leaving the house. I did some changing on system services under location settings. I have a couple games. I dimmed my brightness to almost completely low and have it on auto adjust. I even bought an app to help but it is not quite that useful. The battery runs down to 0 almost every day so I have that once per month charge. How do I improve the battery life? So far nothing has worked! I loved the previouses iPhones but with this one I'm starting to dislike apple... So please any help or suggestions??? Thanks...
(I've already decided my next phone won't be an iPhone)
