Does apple take back iphones with a swollen battery?

About a week ago my iPhone 4's battery started to swell. Right now it is swollen to the point where the back of the phone has almost come off. I was wondering if I can go the apple store and get it checked out. My question is is that will they take my phone and give me a new one/upgrade me to a iPhone 5, or will they just leave me hanging? I don't think I have any warranty on my phone anymore, will that change how they treat me? Please help!

Thank you in advance.

Is this normal for iPhone 4S?

The battery runs out pretty quickly, I unplugged it at about 9:30 and by 10:30 is was 88% I was in the phone to someone till 1 pm and it went down to 15% and then I was talking to him and I went on snapchat and it's down to 5% in 15 minutes, is this normal because I was on the phone?

Normally it lasts about 7 or 8 hours before needing to be charged and that's me using it loads, I literally text all day and I'm also using a lot of Internet apps, is that normal?
