I charged my iPhone overnight. Will this hurt my battery life?

I just got my iPhone 4s replaced because the battery couldn't hold a charge. Now on the second charge of my new phone, I accidently charged the phone overnight, and I think it's dying awfully quickly.

Can someone tell me if overnight charging hurts the phone?

iPhone 4S, iOS 6.1.3, Brand new iPhone 4s

Use iPhone Regularly

For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
