My iphone 4 won't charge on wall charger only on USB

try changing your power adapter

Make sure you're using the new cable and wall adapter that came with the iPhone 4. I too had the same problem trying to use the old wall adapter with the new cable it wouldn't charge. But the old cable works on the computers usb, it's weird. I had to use the new cable and new wall adapter to get it to charge.

My iPhone 3G still charges with any combination of cable and wall adapter.

Chances are it has nothing to do with the wall adapter or cord, try doing a hard reset on the phone by holding down the power and home buttons until it turns off, it may turn back on immediately after, if not wait 15 seconds and power it back up. See if that helps.

A hard reset does not damage anything on your phone. It's just a way to make the phone shut down abruptly and then do a system check when rebooting. 🙂

Your charger is broken. You will have to get a new one. The are covered by the warranty, so it should not cost you anything.

Well simple Amanda. Take it back from where you go it from. If you bought it on line, call apple and they will over night you one. It is under warranty.

Hi amarbadiola!

i got mine last week, and today i m experiencing same issue ! i hope u ve changed your wall charger...i ll try it tomorrow ar vodafone store.

Please keep me updated

Hi Amanda, I have been having the exact same problem. I think the wall jack is bad. Sounds like apple put out a host of bad wall chargers. I need to now figure out how to get a new one.

Yes I am having the same problem the wall charger worked for about 2 weeks and now I can only charge my phone via the USB lead nothing happens when I plug it into the wall socket.

It looks like it was only the charger that was faulty it will be replaced with a new one.

How long is it under warranty?? And what # do I call to actually talk to a PERSON, so I can have them send me a new one?? I tried to call whatever # is listed on their site here and I just got the automated run-around and then it said I needed to purchase a $60 support something or other.

Just ran into the same dilemma. What makes this more helpful is the fact that I have 2 iPhones. There is nothing wrong with the wall charger. It works fine in one phone, but not the other. Like previous posts, I plug it into the USB and it works fine. Upon speaking with a technician today, he was even flustered. What it turns out is the one iPhone I have is not recognizing the wall charger. They are sending a new phone overnight free of charge, since the phones were purchased in February this year. They are covered by a one year warranty. So it seems it's a phone issue (in my case) that they havent encountered since these are the newest ones available. Hope this helps...

Mine has nearly the same issue..
yeas it only charged while on the computer,
and yes it does not charge with the wall charger. BUT
the Iphone has the battery logo like it is charging, but the charge indication light rapidly flashes red and green.
AND this only occurs if the phone battery % is < 80%.
I don't get it..
