Stalone,

Your symptoms have me guessing 2 things.

1: Something is not connected or reassembled correctly, possibly causing a short and resulting in the discharging that you are describing.

2: It's possible that your charging fuse is blown (possibly caused by a short?)

Disassemble your phone again and reassemble, being especially mindful of any contacts that may touch the frame or case that shouldn't. While you're in there, check your fuses. See No Power, No Charging, No iTunes for fuse location.

Did you check your assembly too for any possible shorts like I mentioned? How is the phone still running if you can't charge it? Are you able to charge it when the phone is off?

I think i have the Same problem with ms 3GS 32GB. I wanted to charge my iPhone and when i connected it with the dock-cable it makes a short "beep" and the display gets dark. My repair-service has changed the battery 4 times and also the dock-connector. It don't charge. I tryed another service and they told me: the logicboard is broken. ( the fuses are o.k., i checked them )

And finally the said: there some non-origin Apple-Parts build in. We don't fix it. Because of the warrenty. Warrenty? For a 3,5 Year old iPhone? I'm not interested in a,I want a working phone.

But that's another story....

Tried to replace Battery and Dock connector - but didnt help.

Anyone know what on board can be the reason for this?

Thank you.!

I'm having the same problem! My s3 got water damaged but I'm not sure if thats anything to do with the problem but its charging really slowly and the battery pecentage go down even when charging and it stays on the same pecentage for ages . It only charges fully when I don't touch or use the phone. This same problem happened before a few months ago but I stopped charging it for a few days and used a universal charger and I even tried a new usb cable and battery they didn't work. But after Using the universal charger for about a week I used a decent charger my brother had for his Plus 1 phone and it started working again. But the problems came back and its not the cable or battery I've even cleaned the port. :( I can't return it back because I've had it for months and it has no warranty

I have this problem too. Maybe it's an issue with the dock because the iPhone charges when I plug into my computer.

Update (04/04/2016)

I changed the part that plugs into the wall -problem solved.

Hi Morriskinuthia,

I'm not a technician and am responding based on my experience. You could change your charger and see if that works. Perhaps something in the cable or port is not connecting as it should. Try someone else's charger before you get a new one for yourself.

To fix this issue - 1) change your port or entire charger 2) do not charge any other device in your phone charger. Other devices may cause your charger to overheat and burn the fuse in the port. That's when your phone starts discharging. N.B. I lost a couple of ports so I k

Maybe your cable is bad. Change it as well and make sure not to charge any other devices using your port in the future.
