I continually break my iPhone 4 charger?

It seems like every charger i get for my iPhone 4s, i manage to break it. I'm not sure what I'm doing, but i've gone through maybe 5 or 6 already. Most of the time, they start charging it on and off while i have it plugged in, but my last one just completely stopped suddenly. (my last one was not from apple however, and it has what id call an adapter to go from the cord to my iPhone, which stopped working. With out the iPhone adapter, it still can charge other things) I'm getting very frustrated and was wondering if anyone can help?

Put springs on each end of the cord to prevent splitting wires and try not to bend them to much

Don't bend it as much, and if you have something like a life-proof case or a case that makes it hard to put the charger in consider taking the case off when charging. Also try looking into a "braided i phone charger" the wire is protected on a mesh that looks like rope, i have it having had a problem yet!

Apple phones usually do not like anything that isn't Apple as well (headphones, charges, docs etc) so that's probably why your most recent one isn't working. As for breaking the others, I'd put that down to carelessness as Apple charges are made exceptionally well. The charger you are given in the box when you purchase your phone should last you the amount of time you have that phone for. Just take care of it, leave it be and don't attempt to roll it around itself to often as that will bend the wire casing. If you think you could continuously be getting faulty charges (which is possible) talk to someone in an Apple store to help you out!

If you are continually breaking you iPhone charger then I think it will be good for you to buy the portable charger. You can take it anywhere you like and charge you iPhone whenever you like. It will have less probability of breaking.So, it will be good for you to use portable charger. I think you should check it.

Is the charge port of your iPhone 4 damager? It seems the charger works ok.
