My iPhone 4's battery is starting to drain quicker?

I have an iPhone 4, iOS 6. My brightness is always on the lowest possible setting, I regularly shut down running apps, I don't use any push notifications.
I had a full charge this morning and within two hours it was down to 65%! And I had only even touched it a couple times to see what time it was! So I charged it in math class. Within four hours of again hardly using it, it died. My battery has never done this before! It's only ever died on me once before!
I've deleted some songs, a couple apps that I don't use, and a ton of pictures but my battery is still draining so quickly.
Arrrg! What's wrong with it? Will I have to get a new battery? Or is it something I can fix?

How to not get scammed on Craigslist?

I saw someone selling an iPhone 4 on Craigslist for $180, and it looks like it's in good condition. I really want to get it, but my dad brought up how he got scammed getting an iPod nano from Craigslist, because it wouldn't sync with his computer. I'm worried something like this is going to happen when I get the phone. How can I avoid experiencing problems like this? I'm thinking of just straight up asking the person if it gets detected, or asking if I could use their computer and make sure it works, but I'm worried I'll be too pushy.

IPhone messenger problems anybody?

I sent an iPhone message to a friend earlier this morning. It still says 'delivered' under the message although its said 'read' in some cases but this is the second time I've sent a message to somebody and not received anything back. Does this happen to anybody else or is it just my phone? I guess the other option is they are ignoring me haha but as I said it simply says "delivered"

Dented my iphone5 after a week, is there anything i can do about it?

So i got my iphone 5 last Wednesday and it was so much money after all the activation fees and taxes that i didn't have enough money for a case, i got screen protectors but no case, i was waiting till pay day this week.

well yesterday one of my friends bumped me and i dropped my phone no more than 2 feet onto a hardwood floor, now there's a very small defect in the back top of my phone.

its not really that big of a deal i just hate the fact that its there, like my phone is no longer in perfect condition, can i return it to verizon, or they're prob gonna charge me for another one huh?

i remember the verizon rep telling me i could return it for any reason within a month, and yes i do have insurance on it.

Alternatives to iTunes for Mac OS X?

My sister recently got an iPhone 4S, (I know, I know, Androids are where it's at, and I got an HTC One X) anyways, she got her iPhone and stupid enough, my version of Mac OS X (Tiger) isn't compatible with the newest iTunes, and the 4S isn't compatible with the old iTunes. So she's screwed for music unless she buys it directly from her phone. So does anyone know any alternative programs that would help get around this problem?
