I need to be honest about 5S battery life

That's nothing. I turned 4G on again and I get 7 full days of charge with average work use. There must be something wrong with yours.

Yeah there must be something wrong with OP's.

You get 2-3 days and call it bad. I get barely a day on my Note 3 and my iPhone 5 and that's what I expect (I would expect much more on the Note 3 though). That's smartphones. They have high resolution displays, advanced software, thin profile etc.
