IPhone 4s battery life is dying?

I've had my iPhone 4s for 2 years now, for the past 24 hours it's been bugging out, I've had to buy charger after charger as the wires seem to stop working. Today whenever I charge my phone and use it as the same time, instead of increasing the battery life, it decreases. This is very irritating as I don't know what's wrong with my iPhone.

If the chargers you buy online are cheap that could be the reason. Some chargers will only give it a trickle charge. I would go to AT&T or where ever you can get a real cord. If that's not the problem your battery is just going bad. And you will have to take it to a repair shop to replace it. I have had a 4s for 2 years and I noticed my battery life was not even half what it was when I bought it. I just upgraded to 5s.

A 2 year old battery is shot, replace it
