My iPhone 4S barely charges?

My iphone is like screwed up and now it barely charges to. I've tried many chargers in many outlets and it only charges when I have to replug it in about 6 or 7 times. Why is this happening? My upgrade for verizon isn't until June so I can't replace it and it barely works now.

I'm not 100% sure but maybe your battery is old and worn out? Possibly the connection in your phone is dodgy? Did you drop it? You might have broken a wire.

1-make sure there's no debris in the charging port
2-make sure you are updated to the newest version of ios7 because it has updates specifically for iphone 4/4s

It seems like the charging port of your iPhone screwed up.
If you've only had it for one year, take it to the Apple store.
They'll most likely replace it for you with no questions asked.
