iPhone4S Not Charging

My wife's iPhone4S quit charging. Now it will run all the way to dead, turn itself off, and connecting the charger will turn it back on but then it doesn't charge.

I was going to order the charging port and replace it, but since the port is causing the phone to turn on after it dies, it seems like it could be a software issue (it is/was completely up to date).

Not sure what I should do, I don't know much about troubleshooting things like this. Any help would be much appreciated! Thanks!

With the charger connected or not? Thanks for the quick reply!

Well I tried it and nothing happens but a screen that pops up flashing the battery with a connect to charger symbol. I held it for over a minute. I tried with the connector in and it finally made it to a screen telling me to connect the usb to iTunes. But I can because I think the port may be shot. At least iTunes isn't recognizing the phone.

The phone has no battery left to run a hard reset if a hard reset requires battery power - which I assume it does.

I don't think I made a hard reset happen. Anyway, do you think the port is bad (that I can replace) or a software problem (which would mean I'm screwed). Thanks!

Yeah, it hasn't recognized it since it stopped charging yesterday.

Yes. And held them for over a minute. The warning picture thing for the battery popped up then went away, then popped up again 5-10 seconds later, then never came back and the apple screen never started

Ok thanks for your help

Ok, here's what I know now:

My wife took it to the Apple Store and they hooked it up to something and said it was accepting 1/15 of the charge. They weren't sure why. My wife said they guy at the store told her it could be the connector or something else (she doesn't remember what that something else was).

I left it on the charger all night. Though it didn't show it as charging it charged. Almost like a trickle charge. It went from 0% to 86% in about 5 hours. I took it off and went into the settings and went to "reset" -> "erase all settings and content". After that it was at 83% but still didn't show it being charged when plugged in. About 3 hours later it was at 95% and this morning it was fully charged.

This is all I know. Could it be the port? The battery? Something else? I ordered a new connector port for $11 or something. I guess I'll try that.

Again, any help would be much appreciated!

Anyone?

It seems like it's working fine (normal), but it takes forever to charge. Like hours to get even 5-10% more battery.

I did take it to apple. They said they didn't know what it was and couldn't guarantee a fix.

Plus, it doesn't have the apple care plan so I'm sure it won't be a free fix. I'd rather just do it myself if possible. I'm just looking for input on which part may be faulty
