I have a 5s.

Use it for just what you mentioned. Phone, email, web, text. I think I have like 3 apps.

I personally don't think it runs any better then my 4s did.

I hate the bigger size of the 5. It lives in my front pocket and even though it isn't much bigger, I still prefer the size of 4 to carry in the pocket. And they did the stupid charger change also....
