My iPhone 4s won't charge and its dead

Honestly, no, not until you try to clean it out. I've seen many posts here from people who were surprised by what they got out, hunks of dust & debris they couldn't see by looking in. Give it a shot.

It may be possible that the phone will no longer charge because of the charger itself not functioning properly. I would recommend trying other chargers and other power sources. If that doesn't resolve the issue it definitely sounds like a battery or device hardware issue.

Considering the iPhone 4s is an older phone and judging by your upgrade date. It may actually still be under warranty. You phone comes with a 1 year limited hardware warranty with Apple and you may be able to get it repaired for no cost if it is no longer working.

I recommend starting here:

If you have anymore problems contact apple Support at the link after starting a service request. And advisor would be happy to check your eligibility and explain your options in depth.

What sort of help do you require, other than a suggestion to go and either have it repaired or replaced with a refurbished one for a cost. That is pretty much it if you are waiting for the next iPhone. You should be able to sell the repaired or replaced one.

Inspect the charging port area for dirt/debris/fluff build-up that may be preventing a good connection and use a wooden toothpick, soft clean toothbrush, or a can of compressed air to clean it. Also look for bent or broken pins. Try another cable and/or charger block (be sure to always use a genuine Apple certified brand) in a known good outlet. If you're using a USB port, try another port. If you're using a hub, try a direct connection. If you're using a USB port in the front of a desktop computer, try one in the back. If all these fail, make an appointment at your nearest Genius Bar to have the device evaluated.
