How to fix not charging phone?

Hello,

i have some problem with my iPhone 3gs 16 gb. The problem occured a few months ago when phone randomly shuts down even when battery was charged at 50%. Somehow i manage this but recently phone has died completly. The battery drained out and connecting it to a charger haven't affect phone a bit. So i figure - this must be battery. I bought a new one, but after i have mounted it phone turn on for a few seconds and again - dead. I thought that maybe there is something wrong with a new battery. I charged new battery using two cables, + and - from usb cable which i connected to VCC and GND on battery. I have charged it almost to 80 %. The phone was jailbrokem so i restore a clean 6.1.3. Well this doesn't help at all. When i connect phone to a charger phone detect it, and charging icon appears. The problem is that battery is not charging, but draining very fast. So after few minutes phone is completly discharged, and i cannot turn it on again. Also iPhone is getting very hot when connected to charger. This trick with ring/vibrating button and power/home button doesn't help. Do you have any idea how to fix it? It is not a battery, charger or dock connector failure. It must be logic board issue, but i'm not quite sure how to fix it and why such problem occurs.

Answer this question I have this problem too

Is this a good question?

yeah...too old phone i guess. Some GSM service told me that if would cost me ~ 50$, and it is kind of pointless while i can buy used 3gs for 70-100 $ . I just sell it for parts. I just broke antena from it so now it is complet garbage :)

Do you know what can cause it? I have some 3th party charger, maybe it have dameged my phone?

this can be caused by a bad dock connector, a bad charging IC and/or a bad charging coil.

The same problem was my friend with iPhone 3gs 16 gb, the injury was a capacitor near the Power IC or the Power IC itself. Sorry, but his case was not repaired ever.

Update

It possible, but I think the problem is something that simply happens sometimes,

because, my friend never use a 3th party charger.
