Is it bad to let an iPhone 5 battery die out?

My iphone got sprayed with gasoline? - 2

So the pump sprayed onto me, but nonetheless I took a shower and I think i'm fine. But i was holding my phone and my phone got sprayed with gasoline. I put this question on before but i hadn't specified it was an iphone so I can't remove the battery from it. Luckily it has a case which I have taken off and a screen protector which I have thrown in the trash. I have heard it is bad to use, but i'm wondering what I should do!

Should I get an 8 GB iPhone 4S?

It has come down to this:

- I'm done with Android.
- I already have an 8 GB iPod Touch for music, so wouldn't need a 16 or 32 GB phone.
- I know iPhone 5 just came out, but there are supposed minimal differences. In fact, I like the physical aspect of iPhone 4 better. Shorter, yet stronger.
- I'm always on Wi-Fi (most of the time) because I'm a college student. Don't need 4G, really.
- It is free for Verizon, and my old contract just finished.
